【struts2】配置log4j，设置日志文件保存路径

1. 到pom.xml添加log4j dependency

   1         <groupId>log4j</groupId>
   2             <artifactId>log4j</artifactId>
   3             <version>${log4j.version}</version>
   4         </dependency>

    

2. 到classpath下，如src/main/resources下添加log4j.properties

    1 log4j.projectName=log4j-test-webapp
    2 log4j.rootLogger=DEBUG, FILE
    3 
    4 # define the appender
    5 log4j.appender.FILE=org.apache.log4j.FileAppender
    6 log4j.appender.FILE.File=${catalina.home}/logs/${log4j.projectName}.log
    7 
    8 # define the layout
    9 log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
   10 log4j.appender.FILE.layout.conversionPattern=%d %5p (%c:%L) - %m%n

   其中用于保存log的日志文件位于tomcat下的logs目录。命名为项目名称.log
