【问题描述】：

我正在使用支持 devtools 的 Spring Boot 1.5.6。但是当我更改时，devtools 将尝试重新启动代码。这是抛出Failed to unregister LiveBeansView MBean; nested exception is javax.management.InstanceNotFoundException 错误。

堆栈跟踪：

标签： java spring spring-boot spring-jmx

【解决方案1】：

我可以解决这个问题：这是因为启用了spring.jmx。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 Boot Dashboard 关闭 apring.jmx.enabled。通过选择项目>单击铅笔（编辑）>取消选中启用JMX。
