包含自定义 logback-spring.xml 时，Spring 引导应用程序部署失败并出现 JNDI 警告

Question

当包含自定义 logback 设置文件 (logback-spring.xml) 时，Spring 引导应用程序部署失败并显示 JNDI 调试消息。这只发生在 linux 环境中，并且在 windows 环境中应用程序运行没有任何问题，即使显示了相同的调试消息。

一长串调试消息中的少数

我应该怎么做才能克服这个问题？

Answer 1

尝试将logback-spring.xml 更改为logback.xml。

在这种情况下，Spring Boot 不会使用其模板 (like mentioned here) 配置 logback。

所有关于 JNDI 名称的消息都应该消失了——比如 Spring Boot 中的 logback 自动配置功能。

Answer 2

我遇到了同样的问题，如果您将 logback-spring.xml 更改为 logback.xml，此跟踪将从控制台消失，但它们将写入“.log”文件中。 我不知道如何从控制台和日志文件中删除它们，但至少你可以选择
