spring-vertx-ext

changes in 2.4

• update spring to 5.1.6.RELEASE
• update aspectj to 1.9.2
• update Vert.x to 3.7.0

regular dependency is for Java >=9 (<artifactId>vertx-spring-ext</artifactId>) and a new artifact for Java8 was published with 2.4 (<artifactId>vertx-spring-ext-8</artifactId>)

changes in 2.3

• migrated to Java 9, spring-vertx-ext will be available as Java 9 module in maven central as Java 9 only (java 8 Version will follow, you can still compile it with Java 8)
• the module name is jacpfx.vertx.spring (be aware to include spring dependencies, like "requires spring.context;" )
• Update Vert.x to version 3.5.1
• Update Spring to version 5.0.5.RELEASE

Usage

Add the spring-vertx-ext dependency to your project, in case of maven like this:

        <dependency>
            <groupId>org.jacpfx.vertx.spring</groupId>
            <artifactId>vertx-spring-ext</artifactId>
            <version>2.3</version>
        </dependency>

module vxms.spring.demo {
  requires vxms.core;
  requires spring.context;
  requires jacpfx.vertx.spring;
  requires java.logging;
  requires java.management;
  requires java.ws.rs;
  requires javax.inject;
  requires io.netty.codec.http;

}

changes in 2.2

• Update Vert.x to version 3.5.0
• Update Spring to version 5.0.0.RELEASE
• Update AspectJ to version 1.8.10
• New: Static initializer to create a Spring-aware Verticle without using the Vert.x Factory mechanism. This means you can skip the maven-shade configuration or adding the "java-spring" prefix while deploying a verticle. This change will not affect the existing mechanism.
  • Usage:

  @Component
  @SpringVerticle(springConfig = TestConfiguration.class)
  public class SpringInjectionComponentScanTestVerticle extends AbstractVerticle {
  
      @Autowired
      private SayHelloBean bean;
  
      @Override
      public void start() {
          SpringVerticleFactory.initSpring(this);
          assertNotNull(bean);
         
      }
  }
  

changes in 2.1

You can now inject the Vertx instance to your beans

What it is

A spring-vertx extension which creates spring aware verticles. This extension creates for each spring aware Verticle an own spring context. Spring Verticles can deploy "normal" Verticles and vice versa.

You should use Spring-Verticles in „worker mode“ or use vertx.executeBlocking when calling blocking methods. Avoid blocking the event loop!

Usage

Add the spring-vertx-ext dependency to your project, in case of maven like this:

        <dependency>
            <groupId>org.jacpfx.vertx.spring</groupId>
            <artifactId>vertx-spring-ext</artifactId>
            <version>2.2</version>
        </dependency>

Version 2.1 uses Vert.X 3.3.3 and Spring 4.3.5.RELEASE

To make a Verticle spring aware you first need a (Java) Spring configuration class like this:

@Configuration
@ComponentScan
public class TestConfiguration {
…
}

xml configuration is not supported! (you can import your xml in your java configuration)

Next you create a verticle class and annotate it with @SpringVerticle.

@Component
@SpringVerticle(springConfig=TestConfiguration.class)
public class SpringVerticle extends AbstractVerticle {
    @Inject
    private SayHelloBean bean;

    @Override
    public void start() {
       ...
    }

    @Override
    public void stop() {
       ...
    }
}

To access the Vertx instance in your spring beans, you can inject it by using autowiring :

@Component
public class MyService {
  @Autowired 
  private Vertx vertx;
  ...
}

deployment

In case of using a spring-verticle as the initial verticle of your project, add the prefix "java-spring" to your vertex class.
