### Next Steps



1. Make sure to update the email configuration in `application.properties` with your actual email credentials if you want to test email functionality.

2. You can access the H2 console at `http://localhost:8080/h2-console` to view and manage the database.

3. If you encounter any other issues, please let me know and I'll help you resolve them.

```

spring.datasource.url=jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE

spring.datasource.url=jdbc:h2:file:./data/testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE

ALTER TABLE users 

ALTER COLUMN "displayName" DROP NOT NULL;

UPDATE USERS

SET

    NAME = 'manhng132',

    EMAIL = 'manhng132@gmail.com',

    REMEMBER_DIGEST = '$2b$12$wzHbRL5yLPdDuWXgnQ4M7OZE9GTIL8lFgybX2BAy2T2hWCPBxb2Dq',

    ACTIVATED = TRUE,

    ADMIN = TRUE,

    ACTIVATED_AT = TIMESTAMP '2024-09-14 15:55:09.025402',

    RESET_SENT_AT = TIMESTAMP '2025-05-02 06:47:42.216116'

WHERE ID = 'mb25y6bapfpsmkjk';

```

```

SELECT * FROM USERS

```

```

SELECT * FROM users WHERE email='manhng132@gmail.com'

IntelliJ IDEA: sudo snap install intellij-idea-community --classic



Ctrl + Shift + A → gõ Registry... → Choose.



compiler.automake.allow.when.app.running



Ctrl+Shift+A → Type Build project automatically --> Check.

```

Now you should be able to run the application with `./gradlew bootRun` without any missing class errors. The application will use an H2 in-memory database by default, which is perfect for testing.

```

./gradlew clean build --refresh-dependencies

./gradlew bootRun

```



### -------------------------------------------------



Please analyze the Ruby on Rails project located in the rails_tutorial_sample_app_7th_ed directory on the right.



Then, based on its layout, structure, and functionality, create a Spring application that replicates the app in rails_tutorial_sample_app_7th_ed as closely as possible.



The Spring project and all the code you generate should be created inside the spring-boilerplate directory on the right in code section.



You may modify spring-boilerplate/build.gradle in the right in code section but keep 3.4.5 version to add any required dependencies. Make sure the resulting Spring app and fully screens from rails_tutorial_sample_app_7th_ed/views/ and rails_tutorial_sample_app_7th_ed/views/api for json.



The entire application should use English only – do not include any Vietnamese text.



### --------------------------------------------------

Continue generating only the missing parts of the Spring project in spring-boilerplate without overwriting or changing the existing generated code. 



Continue from where you left off in /spring-boilerplate/src/main/resources/templates/users/show.html and generate the rest of the file. Then proceed to generate any remaining templates and API controllers based on the views/api and views from the original Rails app.



Do not modify already generated files unless absolutely necessary.



### --------------------------------------------------



I'll continue generating the missing parts of the Spring project, starting with completing the `users/show.html` template and then adding any remaining templates and API controllers.



```typescriptreact project="shop-php"

...

```



I've completed the missing parts of the Spring project, including:



1. Finished the `users/show.html` template that was cut off

2. Added all necessary Thymeleaf templates for views:



1. User-related templates (show, index, edit, new, show_follow)

2. Authentication templates (login, password reset)

3. Fragment templates (stats, micropost_form, feed, user_info, etc.)

4. Static pages (home, help, about, contact)

5. Error pages (404, 500, access-denied)



3. Added API controllers to match the Rails app's API functionality:



1. UsersApiController

2. MicropostsApiController

3. RelationshipsApiController

4. AuthApiController

5. PasswordResetApiController

### Avoice Circular Dependency in SecurityConfig



### 1. Use annotation `@Lazy`



Annotation `@Lazy` used to delay bean initialization until it is actually needed



```java

public SecurityConfig(@Lazy CustomUserDetailsService customUserDetailsService,

                      JwtAuthenticationEntryPoint unauthorizedHandler,

                      @Lazy JwtAuthenticationFilter jwtAuthenticationFilter) {

    // ...

}

```



### 2. Refactor SecurityConfig



- Use `SecurityFilterChain` instead of inheriting `WebSecurityConfigurerAdapter` (which has been deprecated)

- Separate authentication and authorization configuration

- Use lambda expressions for HttpSecurity configuration



### 3. Optimize JwtAuthenticationFilter



- Use `@Lazy` for CustomUserDetailsService in filter

- Separate token authentication logic and user information retrieval



### 4. Improve CustomUserDetailsService



- Simplify service to avoid dependency on SecurityConfig



### -------------------------------------------------------



### Fixing Spring Boot Application Issues



I'll address the missing files and dependencies in your Spring Boot application. Let's create the necessary files and update the build.gradle file.



```typescriptreact project="shop-php"

...

```



## Solution for Spring Boot Application Issues



I've created all the missing files that were causing the build errors. Here's what I've added:



### 1. Updated build.gradle



- Added the validation dependency explicitly

- Ensured all JWT dependencies are included



### 2. Added DTO Classes



- UserDto

- LoginDto

- RegisterDto

- ApiResponse

- MicropostDto

- PasswordResetDto

- JwtResponseDto

- RelationshipDto

- PagedResponse



### 3. Added Security Classes



- JwtTokenProvider

- JwtAuthenticationFilter

- JwtAuthenticationEntryPoint

- UserPrincipal

- CurrentUser annotation



### 4. Added Password Reset Functionality



- PasswordResetToken model

- PasswordResetTokenRepository

- PasswordResetTokenService interface

- PasswordResetTokenServiceImpl implementation



### 5. Added Validation Classes



- PasswordMatches annotation

- PasswordMatchesValidator

- ValidEmail annotation

- EmailValidator



### 6. Updated Security Configuration



- SecurityConfig with proper JWT configuration



### 7. Added Application Properties



- Database configuration

- JWT configuration

- Mail configuration

- File upload settings
