ClassNotFoundException: org/springframework/context/support/LiveBeansView 异常在 STS 中重复抛出
ClassNotFoundException: org/springframework/context/support/LiveBeansView exception is thrown repeatedly in STS
我正在使用 STS 开发一个 jhipster 项目。当我在 STS 中将应用程序作为 spring 启动应用程序启动时，我收到以下异常日志。

但如果我在命令提示符下启动应用程序，则没有例外。这让我想知道这是否是 STS 中的问题。有人可以帮忙吗？
这些是 DEBUG 日志语句并与 JMX 相关，因此您可以通过在 logback-spring.xml[=11= 中的“javax.management”上将日志级别设置为 WARN 或 INFO 来在开发中安全地忽略它们]
<logger name="javax.management" level="WARN"/>
只是 MBean 服务器尝试实例化一些 classes 以查看它是否必须通过 JMX 公开它们，如果缺少 class 则不是问题。
为什么它在 STS 中有所不同？我不知道，但可能是 STS 配置日志记录的方式不同。不幸的是，STS 或纯 Eclipse 并未在 JHipster 社区中广泛使用。
