spring - javax.management.InstanceNotFoundException : org. springframework.boot :type=Admin, name=SpringApplication

Question

我开发了一个 Spring boot 应用程序，该应用程序的功能运行良好。但是，在启动时，我多次看到以下异常。

当我几周前运行相同的应用程序时，我没有看到任何此类异常。此后代码库没有改变。我想知道它是否与环境有关。

我发帖的原因是我想更多地了解异常的原因以及如何修复它。当我用谷歌搜索时，我找不到太多帮助。这个here没有工作。

Spring批处理从Oracle DB中提取数据，经过一些处理后将其写入JSON文件。我已经发布了 pom.xml。

Answer 1

我在使用 IDEA IntelliJ 时遇到了同样的问题。问题出在 IntelliJ 的默认服务器配置上。您只需删除“启用启动优化”和“启用 JMX 代理”复选框即可，然后就可以了!

步骤:

• 编辑配置
• 选择您的项目
• 删除“启用启动优化”和“启用 JMX 代理”复选框
