我有2个spring-boot应用程序。每个应用程序都有嵌入式活动mq代理。
我需要在同一台PC上并行运行2个应用程序,但现在不起作用。第一个应用程序总是成功启动:
2018-02-02 11:48:20.095 INFO 7660 --- [ main] s.c.a.AnnotationConfigApplicationContext : Refreshing org.springframework.context.annotation.AnnotationConfigApplicationContext@53045c6c: startup date [Fri Feb 02 11:48:20 MSK 2018]; root of context hierarchy 2018-02-02 11:48:20.923 INFO 7660 --- [ JMX connector] o.a.a.broker.jmx.ManagementContext : JMX consoles can connect to service:jmx:rmi:///jndi/rmi://localhost:7777/jmxrmi 2018-02-02 11:48:20.923 INFO 7660 --- [ main] o.apache.activemq.broker.BrokerService : Using Persistence Adapter: KahaDBPersistenceAdapter[D:\work\arbitrage_robot\root\activemq-data\localhost\KahaDB] 2018-02-02 11:48:21.231 INFO 7660 --- [ main] o.a.a.store.kahadb.MessageDatabase : KahaDB is version 6 2018-02-02 11:48:21.260 INFO 7660 --- [ main] o.a.a.store.kahadb.plist.PListStoreImpl : PListStore:[D:\work\arbitrage_robot\root\activemq-data\localhost\tmp_storage] started 2018-02-02 11:48:21.395 INFO 7660 --- [ main] o.apache.activemq.broker.BrokerService : Apache ActiveMQ 5.15.2 (localhost, ID:ntkachev-60101-1517561301266-0:1) is starting 2018-02-02 11:48:21.441 INFO 7660 --- [ main] o.a.a.t.TransportServerThreadSupport : Listening for connections at: tcp://127.0.0.1:61617?broker.persistent=false 2018-02-02 11:48:21.442 INFO 7660 --- [ main] o.a.activemq.broker.TransportConnector : Connector tcp://127.0.0.1:61617?broker.persistent=false started 2018-02-02 11:48:21.442 INFO 7660 --- [ main] o.apache.activemq.broker.BrokerService : Apache ActiveMQ 5.15.2 (localhost, ID:ntkachev-60101-1517561301266-0:1) started 2018-02-02 11:48:21.442 INFO 7660 --- [ main] o.apache.activemq.broker.BrokerService : For help or more information please see: http://activemq.apache.org 2018-02-02 11:48:23.002 INFO 7660 --- [ main] o.s.j.e.a.AnnotationMBeanExporter : Registering beans for JMX exposure on startup 2018-02-02 11:48:23.021 INFO 7660 --- [ main] o.s.c.support.DefaultLifecycleProcessor : Starting beans in phase 2147483647 2018-02-02 11:48:23.024 INFO 7660 --- [ main] o.a.activemq.broker.TransportConnector : Connector vm://localhost started 2018-02-02 11:48:23.051 INFO 7660 --- [ main] pack.Application : Started Application in 3.337 seconds (JVM running for 3.922)
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 2018-02-02 11:48:31.296 INFO 17008 --- [ main] o.apache.activemq.broker.BrokerService : Using Persistence Adapter: KahaDBPersistenceAdapter[D:\work\app\root\activemq-data\localhost\KahaDB] 2018-02-02 11:48:31.297 INFO 17008 --- [ JMX connector] o.a.a.broker.jmx.ManagementContext : JMX consoles can connect to service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi 2018-02-02 11:48:31.300 INFO 17008 --- [ main] o.a.activemq.store.SharedFileLocker : Database activemq-data\localhost\KahaDB\lock is locked by another server. This broker is now in slave mode waiting a lock to be acquired
这两个应用程序的配置大致相同:
@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); }
以及以下依赖项:
<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(应用程序在启动时挂起)?
您的配置broker.addConnector("tcp://localhost:61616?broker.persistent=false");错误,仅当您使用ActiveMQConnectionFactory,http://activemq.apache.org/how- do-i-embed-a-broker-inside-a- connection.html#HowdoIembedaBrokerinsideaConnection-创建代理时,才能完成此操作使用ActiveMQConnectionFactory
broker.addConnector("tcp://localhost:61616?broker.persistent=false");
ActiveMQConnectionFactory
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; }
