ActiveMQ 在大约 10 000 条消息后给出：“无法连接到代理 URL：tcp://localhost:61616”

Question

ActiveMQ 给出：“javax.jms.JMSException：无法连接到代理 URL：tcp://localhost:61616。原因：java.net.BindException：地址已经在使用：连接”大约 10 000 条消息后

然后一段时间后（大约 1-5 秒）开始接收消息，没有问题。

我正在使用具有非常基本配置的 Spring Boot 2.0.4： spring.activemq.broker-url=tcp://localhost:61616 spring.activemq.user=admin spring.activemq.password=admin spring.activemq.packages.trust-all=true

我使用了 JmsTemplate，现在使用 spring 集成，遗憾的是错误是一样的。

org.springframework.jms.UncategorizedJmsException: Uncategorized exception occurred during JMS processing; nested exception is javax.jms.JMSException: Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.BindException: Address already in use: connect

什么会导致这种类型的错误，我在 activemq 日志中看不到任何内容，但错误是持久的。

Answer 1

解决方案是添加 org.apache.activemq:activemq-pool 并配置 PooledConnectionFactory：

spring.activemq.pool.enabled=true spring.activemq.pool.max-connections=50

在 Spring Boot 中启用池是不够的，因为自动配置会检查依赖关系。
