org.apache.juli.logging.DirectJDKLog 175 日志 - 无法从 ObjectStreamClass$Caches 清除软引用

Question

我收到错误“org.apache.juli.logging.DirectJDKLog 175 日志 - 无法从 Web 应用程序 [ROOT] java.lang.ClassCastExcepti 的 ObjectStreamClass$Caches 中清除软引用 on：类 java.io.ObjectStreamClass$Caches$1 无法转换为类 java.util.Map（java.io.ObjectStreamClass$Caches$1 和 java.util.Map 位于加载程序“bootstrap”的模块 java.base 中）” 这是堆栈信息：

org.apache.juli.logging.DirectJDKLog 175 log - Failed to clear soft references from ObjectStreamClass$Caches for web application [ROOT] java.lang.ClassCastExcepti
on: class java.io.ObjectStreamClass$Caches$1 cannot be cast to class java.util.Map (java.io.ObjectStreamClass$Caches$1 and java.util.Map are in module java.base of loader 'bootstrap')

当我们想在产品环境中播放时，我们发现这个错误。但是当我们在测试环境中播放时，没有任何错误。我不知道为什么，所以有人可以帮助我吗？

Answer 1

我明白了，我的 application.yml 有一些错误。它没有配置，启动项目时，spring不打印调试日志，我们找不到真正的原因。所以这个错误实际上毫无价值。 为什么 spring 不打印真正的原因。因为 spring 默认 deug 是 false；
