1、pom.xml中配置log4j2所使用的jar包
<!-- log4j2 --> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-core</artifactId> <version>${log4j}</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-api</artifactId> <version>${log4j}</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-slf4j-impl</artifactId> <version>${log4j}</version> </dependency> <dependency> <groupId>org.apache.logging.log4j</groupId> <artifactId>log4j-web</artifactId> <version>${log4j}</version> </dependency>
2、在classpath目录中创建log4j2.xml文件
<?xml version="1.0" encoding="UTF-8"?> <Configuration status="INFO" monitorInterval="600"> <!--先定义所有的appender --> <appenders> <!--输出控制台 --> <Console name="Console" target="SYSTEM_OUT"> <ThresholdFilter level="debug" /> <PatternLayout charset="GBK" pattern="%d{HH:mm:ss.SSS} %-5level %class{36} %L %M - %msg%xEx%n" /> </Console> <!--输出到文件--> <File name="LogFile" fileName="${web:rootDir}/logs/app.log" advertise="true"> <PatternLayout pattern="%d %p %C{1.} [%t] %m%n" /> </File> </appenders> <loggers> <!--建立一个默认的root的logger --> <root level="info"> <appender-ref ref="LogFile" /> <appender-ref ref="Console" /> </root> </loggers> </Configuration>
3、web.xml中添加如下信息
<context-param> <param-name>webAppRootKey</param-name> <param-value>webApp.root</param-value> </context-param> <listener> <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class> </listener>
