java - 如何停止Spring的默认输出？

Question

我是 Spring 新手。当我运行 Spring 批处理应用程序时，我希望只看到“Hello World!”，但相反，我得到了以下附加详细信息 -

How to prevent this extra stuff from showing? Thanks.

Additional info- log4j.xml

您可以switch to Log4J logging和 set the log level to ERROR or FATAL 。 这样您就可以停用所有非错误日志记录。

但是戴夫·牛顿是对的:这听起来确实是个坏主意。
