java - Spring boot devtools 无法重新启动应用程序

Question

我正在使用带有 devtools 支持的 Spring Boot 1.5.6。但是当我更改时，开发工具将尝试重新启动代码。这是抛出Failed to unregister LiveBeansView MBean;嵌套异常是 javax.management.InstanceNotFoundException 错误。

堆栈跟踪:

我可以解决这个问题:发生这种情况是因为 spring.jmx 已启用。即使您将应用程序属性设置为 spring.jmx.enabled=false ，它也不起作用。因为如果您将应用程序作为 Spring Boot App 运行。它由 STS 自动启用。

解决方案从启动仪表板关闭 apring.jmx.enabled。通过选择项目>单击铅笔(编辑)>取消选中启用JMX。
