MAVEN项目使用log4j配置输出日志

SSM项目使用Log4j进行操作日志输出

项目环境：Spring+Mybatis+SpringMVC

1.在项目中pom.xml加入log4j包的依赖，更新Maven

<!-- log4j日志文件管理包版本 -->  <properties>    <slf4j.version>1.7.7</slf4j.version>      <log4j.version>1.2.17</log4j.version></properties><!-- 日志文件管理包 -->     <dependency>            <groupId>log4j</groupId>            <artifactId>log4j</artifactId>             <version>${log4j.version}</version>       </dependency>     <dependency>              <groupId>org.slf4j</groupId>              <artifactId>slf4j-api</artifactId>              <version>${slf4j.version}</version>        </dependency>        <dependency>              <groupId>org.slf4j</groupId>              <artifactId>slf4j-log4j12</artifactId>              <version>${slf4j.version}</version>     </dependency>

2.src同级创建并设置log4j.properties

    // 设置    log4j.rootLogger = debug,stdout,D,E    // 输出信息到控制抬     log4j.appender.stdout = org.apache.log4j.ConsoleAppender    log4j.appender.stdout.Target = System.out    log4j.appender.stdout.layout = org.apache.log4j.PatternLayout    log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n    // 输出DEBUG 级别以上的日志到=E://logs/error.log ###    log4j.appender.D = org.apache.log4j.DailyRollingFileAppender    log4j.appender.D.File = E://logs/log.log    log4j.appender.D.Append = true    log4j.appender.D.Threshold = DEBUG     log4j.appender.D.layout = org.apache.log4j.PatternLayout    log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n    // 输出ERROR 级别以上的日志到=E://logs/error.log ###    log4j.appender.E = org.apache.log4j.DailyRollingFileAppender    log4j.appender.E.File =E://logs/error.log     log4j.appender.E.Append = true    log4j.appender.E.Threshold = ERROR     log4j.appender.E.layout = org.apache.log4j.PatternLayout    log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

3.最后一步，在项目/WEB-INF下的web.xml文件中加入监听配置，顺序需注意，listener必须放在后面

<!-- 指定监听器加载的log4j配置文件 -->    <context-param>          <param-name>log4jConfigLocation</param-name>          <param-value>classpath:logback.properties</param-value>      </context-param>      <listener>          <listener-class>              org.springframework.web.util.Log4jConfigListener          </listener-class>      </listener>

4.设置日志内容

package com.mucfc;import org.apache.log4j.Logger;/** *@author linbingwen *@2015年5月18日9:14:21 */public class Test {    private static Logger logger = Logger.getLogger(Test.class);      /**      * @param args      */      public static void main(String[] args) {          // System.out.println("This is println message.");          // 记录debug级别的信息          logger.debug("This is debug message.");          // 记录info级别的信息          logger.info("This is info message.");          // 记录error级别的信息          logger.error("This is error message.");      }  }
