这是我的 Spring boot 应用程序中的简单代码：

package com.maxxton.SpringBootHelloWorld;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringBootHelloWorldApplication {

  public static void main(String[] args) {
    SpringApplication.run(SpringBootHelloWorldApplication.class, args);
  }
}

还有一个 ApplicationListener 类来监听 ApplicationEvent：

package com.maxxton.SpringBootHelloWorld;

import org.springframework.context.ApplicationEvent;
import org.springframework.context.ApplicationListener;
import org.springframework.stereotype.Component;

@Component
public class Test implements ApplicationListener {

  @Override
  public void onApplicationEvent(ApplicationEvent event) {
    if (event.getClass().getSimpleName().equals("ApplicationReadyEvent")) {
      System.out.println("-------------------------------------");
      System.out.println(event.getClass().getSimpleName());
      System.out.println("-------------------------------------");
    }
  }
}

build.gradle 包含这些依赖项：

dependencies {

    compile("org.springframework.boot:spring-boot-starter-amqp")
    compile("org.springframework.cloud:spring-cloud-starter-bus-amqp")

    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter')
    compile("org.springframework.cloud:spring-cloud-starter")
    compile("org.springframework.cloud:spring-cloud-starter-security")
    compile("org.springframework.cloud:spring-cloud-starter-eureka")
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

现在，当我运行这个 Spring Boot 应用程序时，我看到这个日志打印了两次：

[main] c.m.S.SpringBootHelloWorldApplication : Started …
