IDEA 2016.1 Maven SpringMVC学习教程_log日志的生成（三）

本文主要是介绍IDEA 2016.1 Maven SpringMVC学习教程_log日志的生成（三），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1、log4j.properties配置

### 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 级别以上的日志到文件F://logs/debug.log ###
log4j.appender.D = org.apache.log4j.FileAppender
log4j.appender.D.File = F://IDEA//debug.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 级别以上的日志到文件F://logs/error.log ###
log4j.appender.E = org.apache.log4j.FileAppender
log4j.appender.E.File = F://IDEA//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

2、web.xml配置

<!-- Log4j配置 -->
<context-param><param-name>webAppRootKey</param-name><param-value>webapp.root</param-value>
</context-param>
<!--设置环境变量，指定log4j的配置文件-->
<context-param><param-name>log4jConfigLocation</param-name><param-value>classpath:log4j/log4j.properties</param-value>
</context-param>
<listener><listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

3、HomeController.java

// 注解标注此类为springmvc的controller，url映射为"/home"
@Controller
@RequestMapping("/home")
public class HomeController {//添加一个日志器
    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);//映射一个action
    @RequestMapping("/index")public  String index(){//输出日志文件
        logger.info("the first jsp pages");logger.debug("第一个springMVC应用程序！");//返回一个index.jsp这个视图
        return "index";}
}
