好的。这里的故障线路是：

STWLogger.getLogger（）.debug（“未找到“+businessUnit+”\n为businessUnit设置默认值的参数配置”）；

我找不到要通过直接分析确认的

STWLogger

类的源代码，但从stacktrace中可以看出，它试图通过Log4j显式实例化日志系统，而不是依赖于标准日志API SLF4J，后者将在运行时选择适当的日志系统

这里的问题是，您应用的Spring Boot的标准配置中没有Log4j。实际上，Spring Boot将导入并使用Logback作为类路径中的默认日志解决方案，由starter

Spring Boot starter logging

提供，它是您在

pom.xml

中使用的starter

Spring Boot starter web

的依赖项

我认为你有两种解决办法

通过调用SLF4J API来替换故障线路，该API将自动使用Logback。可能是这样的：

package org.mypackage；
导入org.slf4j.Logger；
导入org.slf4j.LoggerFactory；
公共类测试日志{
私有静态最终记录器Logger=LoggerFactory.getLogger（TestLog.class）；
公开无效测试（）{
LOGGER.info（“您的日志”）；
}
}

在Spring引导应用程序中用Log4j替换Logback。您可以按照以下指南进行操作：

您可以发布应用程序使用的建筑配置（

pom.xml

或

build.gradle

build.gradle.kts

）吗？我已经添加了pom.xml文件。我尝试了选项2，但不幸的是，我没有成功。请你一步一步地告诉我，对于选项1，我应该做什么？我使用了第二种方法，使用了你共享的链接，但错误仍然存在。另外，我在pom.xml文件中做了一些更改。你能帮我看看吗？谢谢您可以尝试第一种方法。只需使用我在示例中在文件顶部设置的导入，在该文件的类下创建

LOGGER

类成员，并将调用

STWLogger.getLogger（）.debug（…

替换为

LOGGER.debug（…

）。
