用log4j管理tomcat的catalina日志

r3421555

下载以下jar包

log4j-1.2.17.jar (http://www.apache.org/dist/logging/log4j/1.2.17/ )

tomcat-juli.jar (http://www.apache.org/dist/tomcat) 找到对应版本下载

tomcat-juli-adapters.jar (http://www.apache.org/dist/tomcat) 同上

1、将以上三个jar都放入tomcat/lib目录下。

2、将tomcat-juli.jar 替换tomcat/bin目录下的对应jar包(建议将原来的jar重命名)

3、将tomcat/conf/contxt.xml文件中<context>标签修改为：<Context swallowOutput="true">（swallowOutput="true" 的属性配置，主要用于将tomcat的stdout给接管过来）

4、重命名或者删除tomcat/conf/logging.properties 文件

5、在tomcat/lib目录下新建 log4j.properties 文件并添加以下内容

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43
