Question

我正在尝试在我的机器中运行mvc示例代码。我已经注释了所有Log4j导入并在代码中注释了所有的logger语句。但是仍然在控制台中收到警告。我删除了包含log4j.properties的资源文件夹。

如果您不想要任何日志记录，您可以安全地忽略该WARN消息，它只表示没有完成log4j配置。

如果您的问题只是以下警告，

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.

添加log4j.properties并添加以下单行，它不会显示警告并关闭所有日志记录。

log4j.rootLogger=OFF

删除log4j相关文件后Log4j警告
