我完全无能为力,第二条线来自哪里.
编辑：
很奇怪：我收到WARN消息,尽管事实上我只将所有可能的threasholds和东西设置为INFO ……？
最佳答案
因为您只声明了一个appender,并且重复日志的格式不同,所以很明显您有多个日志框架同时进行：
> log4j在您自己的代码中
>在Spring内部进行公共记录
你需要做的是：
>从类路径中删除commons-logging依赖项.如果您使用的是maven,则必须从每个Spring模块中排除commons-logging jar.
>将jcl-over-slf4j添加到类路径中
Maven示例(如何删除commons-logging)：注意：在每个Spring依赖项中都需要这种排除语法
Maven示例(如何添加slf4j,您可能已经这样做了)：
slf4j-api 如果您不使用Maven,请告诉我,我会尽力帮助您了解您的特定环境.
