.Source Code

****

If you'd like to get right to it, the https://github.com/mraible/jhipster6-demo[source code for this application is on GitHub]. To run the app, use `./mvnw`. To test it, run `./mvnw verify`. To run its end-to-end tests, run `./mvnw` in one terminal and `npm run e2e` in another.

== What is JHipster?

JHipster is one of those open-source projects you stumble upon and immediately think, "`Of course!`" It combines three very successful frameworks in web development: Bootstrap, Angular, and Spring Boot. Bootstrap was one of the first dominant web-component frameworks. Its most substantial appeal was that it only required a bit of HTML and it worked! All the efforts we made in the Java community to develop web components were shown a better path by Bootstrap. It leveled the playing field in HTML/CSS development, much like Apple's Human Interface Guidelines did for iOS apps.

https://www.julien-dubois.com/[Julien Dubois] started JHipster in October 2013 (Julien's first commit was on https://github.com/jhipster/generator-jhipster/commit/c8630ab7af7b6a99db880b3b0e2403806b7d2436[October 21, 2013]). The first public release (version 0.3.1) launched on December 7, 2013. Since then, the project has had over 194 releases! It is an open-source, Apache 2.0-licensed project on GitHub. It has a core team of 29 developers and over 500 contributors. You can find its homepage at https://www.jhipster.tech/[www.jhipster.tech]. If you look at https://github.com/jhipster/generator-jhipster[the project on GitHub], you can see it's mostly written in JavaScript (36%) and Java (28%).

JHipster 6 is the same JHipster many developers know and love, with a couple of bright and shiny new features: namely Java 11 and Spring Boot 2.1 support.

== Install JHipster 6

The http://www.jhipster.tech/installation/[Installing JHipster] instructions show you all the tools you'll need to use a released version of JHipster.

. Install Java 11 https://sdkman.io/[using SDKMAN!]

. Install Git from https://git-scm.com.

. Install Node.js from http://nodejs.org. JHipster recommends using a LTS release.

. Run the following command to install JHipster.

    npm i -g [email protected]

NOTE: If you're using Yarn, run `yarn global add [email protected]`.

== Create a Project

To create a project, open a terminal window and create a directory. For example, `mkdir blog`. Navigate into the directory and run `jhipster`. You'll be prompted to answer a number of questions about the type of application you want to create and what features you'd like to include. The screenshot below shows the choices I made to create a simple blog application with Angular.

.Generating the application

image::static/generating-blog.png[Generating the application, 800, scaledwidth=100%]

If you'd like to create the same application I did, you can place the following `.yo-rc.json` file in an empty directory and run `jhipster` in it. You won't be prompted to answer any questions because the answers are provided by this file.

TIP: **What about React?** If you'd like to see how to use JHipster to build a React app, see https://developer.okta.com/blog/2018/06/25/react-spring-boot-photo-gallery-pwa[Build a Photo Gallery PWA with React, Spring Boot, and JHipster].

The project creation process will take a couple of minutes to run, depending on your internet connection speed. When it's finished, you should see output like the following.

.Generation success

image::static/generation-success.png[Generation success, 800, scaledwidth=100%]

Run `./mvnw` to start the application and navigate to http://localhost:8080 in your favorite browser. The first thing you'll notice is a hipster explaining how you can sign in or register.

.Default homepage

image::static/default-homepage.png[Default homepage, 800, scaledwidth=100%]

Sign in with username `admin` and password `admin`, and you'll have access to navigate through the Administration section. This section offers nice looking UIs on top of some Spring Boot's many monitoring and configuration features. It also allows you to administer users:

.User management

image::static/user-management.png[User management, 800, scaledwidth=100%]

It gives you insights into Application and JVM metrics:

.Application metrics

image::static/app-metrics.png[Application and JVM Metrics, 800, scaledwidth=100%]

And it allows you to see the Swagger docs associated with its API.

.Swagger docs

image::static/swagger-ui.png[Swagger UI, 800, scaledwidth=100%]

You can run the following command (in a separate terminal window) to run the Protractor tests and confirm everything is working correctly.

----

npm run e2e

----

== Generate Entities

For each entity you want to create, you will need:

* a database table;

* a Liquibase change set;

* a JPA entity class;

* a Spring Data `JpaRepository` interface;

* a Spring MVC `RestController` class;

* an Angular list component, edit component, service; and

* several HTML pages for each component.

Also, you should have integration tests to verify that everything works and performance tests to confirm that it runs fast. In an ideal world, you'd also have unit tests and integration tests for your Angular code.

The good news is JHipster can generate all of this code for you, including integration tests and performance tests. Also, if you have entities with relationships, it will create the necessary schema to support them (with foreign keys), and the TypeScript and HTML code to manage them. You can also set up validation to require certain fields as well as control their length.

JHipster supports several methods of code generation. The first uses its https://www.jhipster.tech/creating-an-entity/[entity sub-generator]. The entity sub-generator is a command-line tool that prompts you with questions which you answer.

https://start.jhipster.tech/jdl-studio/[JDL-Studio] is a browser-based tool for defining your domain model with JHipster Domain Language (JDL). I like the visual nature of JDL-Studio, so I'll use it for this project.

Below is the entity diagram and JDL code needed to generate a simple blog with blogs, entries, and tags.

.Blog entity diagram

image::static/jdl-studio.png[Blog entity diagram, 1171, scaledwidth=100%]

TIP: You can find a few other https://github.com/jhipster/jdl-samples[JDL samples on GitHub].

If you'd like to follow along, copy/paste the contents of the JDL below into a `blog.jdl` file.

.blog.jh

----

entity Blog {

  name String required minlength(3),

  handle String required minlength(2)

}

entity Entry {

  title String required,

  content TextBlob required,

  date Instant required

}

entity Tag {

  name String required minlength(2)

}

relationship ManyToOne {

  Blog{user(login)} to User,

  Entry{blog(name)} to Blog

}

relationship ManyToMany {

  Entry{tag(name)} to Tag{entry}

}

paginate Entry, Tag with infinite-scroll

----

Run the following command to import this file and generate entities, tests, and a UI.

----

jhipster import-jdl blog.jdl

----

You'll be prompted to overwrite `src/main/resources/config/liquibase/master.xml`. Type **a** to overwrite this file, as well as others.

Restart the application with `/.mvnw`.

You might notice that each entities list screen is pre-loaded with data. This is done by https://github.com/marak/Faker.js/[faker.js]. To turn it off, edit `src/main/resources/config/application-dev.yml`, search for `faker` and remove it from the `liquibase.contexts` configuration. I made this change in this example's code.

[source,yaml]

----

liquibase:

 # Add 'faker' if you want the sample data to be loaded automatically

 contexts: dev

----

TIP: If you still have data in your list screens after making this change, run `./mvnw clean` to delete the H2 database.

Create a couple of blogs for the existing `admin` and `user` users, as well as a few blog entries.

.Blogs

image::static/blogs.png[Blogs, 800, scaledwidth=100%]

.Entries

image::static/entries.png[Entries, 800, scaledwidth=100%]

From these screenshots, you can see that users can see each other's data, and modify it.

== Add Business Logic

TIP: To configure an IDE with your JHipster project, see https://www.jhipster.tech/configuring-ide/[Configuring your IDE]. Instructions exist for Eclipse, IntelliJ IDEA, Visual Studio Code, and NetBeans.

To add more security around blogs and entries, open `BlogResource.java` and find the `getAllBlogs()` method. Change the following line:

[source,java]

.src/main/java/org/jhipster/blog/web/rest/BlogResource.java

----

return blogRepository.findAll();

----

To:

[source,java]

.src/main/java/org/jhipster/blog/web/rest/BlogResource.java

----

return blogRepository.findByUserIsCurrentUser();

----

The `findByUserIsCurrentUser()` method is generated by JHipster in the `BlogRepository` class and allows limiting results by the current user.

[source,java]

.src/main/java/org/jhipster/blog/repository/BlogRepository.java

----

public interface BlogRepository extends JpaRepository {

    @Query("select blog from Blog blog where blog.user.login = ?#{principal.username}")

    List findByUserIsCurrentUser();

}

----

After making this change, re-compiling `BlogResource` should trigger a restart of the application thanks to http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html[Spring Boot's Developer tools]. If you navigate to http://localhost:8080/blog, you should only see the blog for the current user.

.Admin's blog

image::static/blogs-admin.png[Admin's blog, 800, scaledwidth=100%]

To add this same logic for entries, open `EntryResource.java` and find the `getAllEntries()` method. Change the following line:

[source,java]

.src/main/java/org/jhipster/blog/web/rest/EntryResource.java

----

Page page;

if (eagerload) {

    page = entryRepository.findAllWithEagerRelationships(pageable);

} else {

    page = entryRepository.findAll(pageable);

}

----

To:

[source,java]

.src/main/java/org/jhipster/blog/web/rest/EntryResource.java

----

page = entryRepository.findByBlogUserLoginOrderByDateDesc(SecurityUtils.getCurrentUserLogin().orElse(null), pageable);

----

Using your IDE, create this method in the `EntryRepository` class. It should look as follows:

[source,java]

.src/main/java/org/jhipster/blog/repository/EntryRepository.java

----

Page findByBlogUserLoginOrderByDateDesc(String currentUserLogin, Pageable pageable);

----

Recompile both changed classes and verify that the `user` user only sees the entries you created for them.

.User's entries

image::static/entries-user.png[User's entries, 800, scaledwidth=100%]

You might notice that this application doesn't look like a blog and it doesn't allow HTML in the content field.

== Make UI Enhancements

When doing UI development on a JHipster-generated application, it's nice to see your changes as soon as you save a file. JHipster uses https://www.browsersync.io/[Browsersync] and https://webpack.github.io/[webpack] to power this feature. You enable this feature by running the following command in the `blog` directory.

----

npm start

----

In this section, you'll change the following:

. Change the rendered content field to display HTML

. Change the list of entries to look like a blog

=== Allow HTML

If you enter HTML in the `content` field of a blog entry, you'll notice it's escaped on the list screen.

.Escaped HTML

image::static/entries-with-html-escaped.png[Escaped HTML, 800, scaledwidth=100%]

To change this behavior, open `entry.component.html` and change the following line:

[source,html]

.src/main/webapp/app/entities/entry/entry.component.html

----

{{entry.content}}

----

To:

[source,html]

.src/main/webapp/app/entities/entry/entry.component.html

----

----

After making this change, you'll see that the HTML is no longer escaped.

.HTML in entries

image::static/entries-with-html.png[Escaped HTML, 800, scaledwidth=100%]

=== Improve the layout

To make the list of entries look like a blog, replace `
` with HTML, so it uses a stacked layout in a single column.

[source,html]

.src/main/webapp/app/entities/entry/entry.component.html

----

 0">

    = links['last']" [infiniteScrollDistance]="0">

        

            

                {{entry.title}}

            

            Posted on {{entry.date | date: 'short'}} by {{entry.blog.user.firstName}}

            

            

                

                    

                    Edit

                

                

                    

                    Delete

                

            

        

    



----

Now it looks more like a regular blog!

.Blog entries

image::static/blog-entries.png[Blog entries, 800, scaledwidth=100%]

=== Lock It Down!

You can further enhanced the security of your API by only allowing users that own a blog (or entry) to edit it. Here's some sudo-code to show the logic:

[source,java]

----

Optional blog = blogRepository.findById(id);

if (blog.isPresent() && ) {

    return new ResponseEntity<>("error.http.403", HttpStatus.FORBIDDEN);

}

return ResponseUtil.wrapOrNotFound(blog);

----

Below is the refactored `BlogResource.java` with additional logic in each method to prevent data tampering.

.src/main/java/org/jhipster/blog/web/rest/BlogResource.java

[source,java]

----

@PostMapping("/blogs")

public ResponseEntity> createBlog(@Valid @RequestBody Blog blog) throws URISyntaxException {

    log.debug("REST request to save Blog : {}", blog);

    if (blog.getId() != null) {

        throw new BadRequestAlertException("A new blog cannot already have an ID", ENTITY_NAME, "idexists");

    }

    if (!blog.getUser().getLogin().equals(SecurityUtils.getCurrentUserLogin().orElse(""))) {

        return new ResponseEntity<>("error.http.403", HttpStatus.FORBIDDEN);

    }

    Blog result = blogRepository.save(blog);

    return ResponseEntity.created(new URI("/api/blogs/" + result.getId()))

        .headers(HeaderUtil.createEntityCreationAlert(applicationName, true, ENTITY_NAME, result.getId().toString()))

        .body(result);

}

@PutMapping("/blogs")

public ResponseEntity> updateBlog(@Valid @RequestBody Blog blog) throws URISyntaxException {

    log.debug("REST request to update Blog : {}", blog);

    if (blog.getId() == null) {

        throw new BadRequestAlertException("Invalid id", ENTITY_NAME, "idnull");

    }

    if (blog.getUser() != null &&

        !blog.getUser().getLogin().equals(SecurityUtils.getCurrentUserLogin().orElse(""))) {

        return new ResponseEntity<>("error.http.403", HttpStatus.FORBIDDEN);

    }

    Blog result = blogRepository.save(blog);

    return ResponseEntity.ok()

        .headers(HeaderUtil.createEntityUpdateAlert(applicationName, true, ENTITY_NAME, blog.getId().toString()))

        .body(result);

}

@GetMapping("/blogs/{id}")

public ResponseEntity> getBlog(@PathVariable Long id) {

    log.debug("REST request to get Blog : {}", id);

    Optional blog = blogRepository.findById(id);

    if (blog.isPresent() && blog.get().getUser() != null &&

        !blog.get().getUser().getLogin().equals(SecurityUtils.getCurrentUserLogin().orElse(""))) {

        return new ResponseEntity<>("error.http.403", HttpStatus.FORBIDDEN);

    }

    return ResponseUtil.wrapOrNotFound(blog);

}

@DeleteMapping("/blogs/{id}")

public ResponseEntity> deleteBlog(@PathVariable Long id) {

    log.debug("REST request to delete Blog : {}", id);

    Optional blog = blogRepository.findById(id);

    if (blog.isPresent() && blog.get().getUser() != null &&

        !blog.get().getUser().getLogin().equals(SecurityUtils.getCurrentUserLogin().orElse(""))) {

        return new ResponseEntity<>("error.http.403", HttpStatus.FORBIDDEN);

    }

    blogRepository.deleteById(id);

    return ResponseEntity.noContent().headers(HeaderUtil.createEntityDeletionAlert(applicationName, true, ENTITY_NAME, id.toString())).build();

}

----

You'll need to make similar changes in `EntryResource.java`. See https://github.com/mraible/jhipster6-demo/commit/73bd82f87274dc013a72839eda5925b5e22f4907[this commit] for all the changes that you'll need in these two classes, as well as their integration tests.

== Deploy to the Cloud

A JHipster application can be deployed anywhere a Spring Boot application can be deployed.

JHipster ships with support for deploying to https://www.jhipster.tech/cloudfoundry/[Cloud Foundry], https://www.jhipster.tech/heroku/[Heroku], https://www.jhipster.tech/kubernetes/[Kubernetes], https://www.jhipster.tech/aws/[AWS], and https://www.jhipster.tech/boxfuse/[AWS with Boxfuse]. I'm using Heroku in this example because it doesn't cost me anything to host it.

When you prepare a JHipster application for production, it's recommended to use the pre-configured "`production`" profile. With Maven, you can package your application by specifying the `prod` profile when building.

----

./mvnw -Pprod verify

----

The production profile is used to build an optimized JavaScript client. You can invoke this using webpack by running `yarn run webpack:prod`.

The production profile also configures gzip compression with a servlet filter, cache headers, and monitoring via

https://micrometer.io/[Micrometer]. If you have a http://graphite.wikidot.com/[Graphite] server configured in

your `application-prod.yml` file, your application will automatically send metrics data to it.

When you run this command, you'll likely get a test failure.

----

[ERROR] Failures:

[ERROR]   BlogResourceIT.createBlog:115 Status expected:<201> but was:<500>

[ERROR]   BlogResourceIT.getAllBlogs:189 Status expected:<200> but was:<500>

[INFO]

[ERROR] Tests run: 144, Failures: 2, Errors: 0, Skipped: 0

----

The reason this happens is in a stack trace in your terminal.

----

org.springframework.dao.InvalidDataAccessApiUsageException: Authentication object cannot be null

----

To fix this, you can use Spring Security Test's http://docs.spring.io/spring-security/site/docs/current/reference/html/test-method.html#test-method-withmockuser[`@WithMockUser`]. Open `BlogResourceIT.java` and inject  `UserRepository` as a dependency.

[source,java]

.src/test/java/org/jhipster/blog/web/rest/BlogResourceIT.java

----

@Autowired

private UserRepository userRepository;

----

Change the `createEntity()` method so it's not `static` and uses the `userRepository` to set a user on the blog entity.

[source,java]

----

public Blog createEntity(EntityManager em) {

    Blog blog = new Blog()

            .name(DEFAULT_NAME)

            .handle(DEFAULT_HANDLE)

            .user(userRepository.findOneByLogin("user").get());

    return blog;

}

----

Add `@WithMockUser` to the `createBlog()`, `getAllBlogs()`, `getBlog()`, `updateBlog()` and `deleteBlog()` methods. Below is an example of how each method should look.

[source,java]

----

@Test

@Transactional

@WithMockUser

public void createBlog() throws Exception {

    // method body

}

----

After fixing this test, you should be able to run `./mvnw -Pprod verify` without any failures.

To deploy this application to Heroku, I logged in to my account using `heroku login` from the command line. I already had the https://devcenter.heroku.com/articles/heroku-command-line[Heroku CLI] installed.

----

$ heroku login

== JHipster: Accelerating Spring Boot + Angular Development

I hope you've enjoyed learning how JHipster can help you develop modern web applications! It's a nifty project, with an easy-to-use entity generator, a pretty UI, and many Spring Boot best-practice patterns. The project team follows five simple https://www.jhipster.tech/policies/[policies], paraphrased here:

1. The development team votes on policies.

2. JHipster uses technologies with their default configurations as much as possible.

3. Only add options when there is sufficient added value in the generated code.

4. For the Java code, follow the default IntelliJ IDEA formatting and coding guidelines.

5. Use strict versions for third-party libraries.

These policies help the project maintain its sharp edge and streamline its development process. If you have features you'd like to add or if you'd like to refine existing features, you can https://github.com/jhipster/generator-jhipster[watch the project on GitHub] and https://github.com/jhipster/generator-jhipster/blob/master/CONTRIBUTING.md[help with its development] and support. We're always looking for help!

Now that you've learned how to use Angular, Bootstrap 4, and Spring Boot with JHipster, go forth and develop great applications!

TIP: Developing microservices with JHipster is possible too! See https://developer.okta.com/blog/2019/05/23/java-microservices-spring-cloud-config[Java Microservices with Spring Cloud Config and JHipster] to learn how.
