Spring for Apache Pulsar provides a basic Spring-friendly API for developing https://pulsar.apache.org/[Apache Pulsar] applications.



**#TIP#**: Most of the ideas in this project are borrowed from the Spring for Apache Kafka project, thus a familiarity with it would help.



== Getting Started

The {docs}[reference documentation] includes a {docs}/reference/pulsar.html#quick-tour[quick tour] section.



== Getting Help

Are you having trouble with Spring for Apache Pulsar? We want to help!



* Check the {docs}[reference documentation]

* Learn the Spring basics -- Spring for Apache Pulsar builds on many other Spring projects; check the https://spring.io[spring.io] website for a wealth of reference documentation.

If you are new to Spring, try one of the https://spring.io/guides[guides].

// TODO (NYI): * If you are upgrading, read the {github}/wiki[release notes] for upgrade instructions and "new and noteworthy" features.

* Ask a question -- we monitor https://stackoverflow.com[stackoverflow.com] for questions tagged with https://stackoverflow.com/tags/spring-pulsar[`spring-pulsar`].

* Report bugs with Spring for Apache Pulsar at {github}/issues[github.com/spring-projects/spring-pulsar/issues].



== Reporting Issues

Spring for Apache Pulsar uses GitHub's integrated issue tracking system to record bugs and feature requests.

If you want to raise an issue, please follow the recommendations below:



* Before you log a bug, please search the {github}/issues[issue tracker] to see if someone has already reported the problem.

* If the issue doesn't already exist, {github}/issues/new[create a new issue].

* Please provide as much information as possible with the issue report.

We like to know the Spring for Apache Pulsar version, operating system, and JVM version you're using.

* If you need to paste code or include a stack trace, use Markdown +++```+++ escapes before and after your text.

* If possible, try to create a test case or project that replicates the problem and attach it to the issue.



== Building from Source

You don't need to build from source to use Spring for Apache Pulsar (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring for Apache Pulsar can be built and published to your local Maven cache using the https://docs.gradle.org/current/userguide/gradle_wrapper.html[Gradle wrapper].

You also need JDK 17.



[source,shell]

----

./gradlew publishToMavenLocal

----



This will build all jars and documentation and publish them to your local Maven cache.

It won't run any of the tests.

If you want to build everything and run tests, use the `build` task:



[source,shell]

----

./gradlew build

----



NOTE: Some tests rely on a Docker daemon to test against live services using https://www.testcontainers.org/[Testcontainers].

These tests will be skipped if a local Docker daemon is not available.



The above command will build everything and run all unit tests and integration tests except the `PulsarFunctionAdministrationIntegrationTests` which requires the _Pulsar RabbitMQ Connector_ to be downloaded prior to running.

To download the connector (one time only) and run the integration test, add a system property to the task as follows:



[source,shell]

----

./gradlew build -DdownloadRabbitConnector=true

----



By default, the `build` command will run unit tests followed by integration tests.

If you want skip tests, use the `-x test` and/or `-x integrationTest` options:



[source,shell]

----

./gradlew build -x test -x integrationTest

----



== Modules

There are several modules in Spring for Apache Pulsar. Here is a quick overview:



=== spring-pulsar

The main library that provides the API to access Apache Pulsar.



=== spring-pulsar-bom

Provides a Maven BOM (https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#bill-of-materials-bom-poms[Bill of Materials]) that recommends a consistent version for all Spring for Apache Pulsar published modules.



=== spring-pulsar-cache-provider

Provides the interfaces for the cache provider used by the main library to cache producers.



=== spring-pulsar-cache-provider-caffeine

Provides the implementation of the cache provider using a shaded version of Caffeine.



=== spring-pulsar-dependencies

Provides a Gradle https://docs.gradle.org/current/userguide/java_platform_plugin.html[java-platform] that recommends dependency versions.



=== spring-pulsar-docs

Provides reference docs and handles aggregating javadocs.



=== spring-pulsar-reactive

Provides the API to access Apache Pulsar using a Reactive client.



=== spring-pulsar-sample-apps

Provides sample applications to illustrate Spring for Apache Pulsar functionality as well as provide ability for quick manual verification during development.



=== spring-pulsar-test

Provides utilities to help with testing Spring for Apache Pulsar applications.
