我有2个spring-boot应用程序.每个应用程序都嵌入了活动的mq代理.

我需要在同一台PC上同时运行2个应用程序,但它现在不起作用.第一个应用始终成功启动：

但第二次冻结并打印：

2018-02-02 11:48:30.450  INFO 17008 --- [           main] s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@53045c6c: startup date [Fri Feb 02 11:48:30 MSK 2018]; root of context hierarchy

两个应用程序具有大致相同的配置：

@SpringBootApplication
public class Application {

  @Bean
  public BrokerService broker() throws Exception {
    BrokerService broker = new BrokerService();
    broker.addConnector("tcp://localhost:61616?broker.persistent=false");
    return broker;
  }

  @JmsListener(destination = "robotCommand")
  public void listen(String in) {
      System.out.println(in);
  }

以及依赖关系：

   <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-kahadb-store</artifactId>
        <version>5.15.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-broker</artifactId>
        <version>5.15.2</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-activemq</artifactId>
        <version>1.5.10.RELEASE</version>
    </dependency>

我该如何解决这个问题(启动时挂起的应用程序)？

解决方法:

你的config broker.addConnector(“tcp：// localhost：61616？broker.persistent = false”);如果使用ActiveMQConnectionFactory,http://activemq.apache.org/how-do-i-embed-a-broker-inside-a-connection.html#HowdoIembedaBrokerinsideaConnection-UsingActiveMQConnectionFactory创建代理,则可以执行此操作

Using ActiveMQConnectionFactory
An embedded broker can also be created using an ActiveMQConnectionFactory and using a vm connector as a uri. e.g.
ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory("vm://localhost?broker.persistent=false");

尝试

 @Bean
  public BrokerService broker() throws Exception {
    BrokerService broker = new BrokerService();
    broker.addConnector("tcp://localhost:61616");
    broker.setPersistent(false);
    return broker;
  }
