• 导入依赖的jar包

　　

     
      1.2.16
      
     
         
      
       org.slf4j
          
      
       slf4j-log4j12
          
      
       ${slf4j.version}
      
     

• web.xml中配置Log4j

　　

      
          
      
       org.springframework.web.util.Log4jConfigListener
       
     
     
         
      
       log4jConfigLocation
          
      
       classpath:log4j.xml
      
     
     
         
      
       errorLevel
          
      
       ERROR
      
     
         
      
       infoLevel
          
      
       INFO
      
     
         
      
       debugLevel
          
      
       DEBUG
      
     
         
      
       rootLevel
          
      
       ALL
      
     

• mybatis-config.xml

 

 

 

 

• 引入Log4j.xml配置文件

 

 

注意：动态配置<level value="${infoLevel}" />这样的方式level读取不到web.xml中的值，都是debug，具体原因不清楚

• 调用

 

public class UserController {    private static Logger logger = LoggerFactory.getLogger(UserController.class);    private static Logger debugLogger = LoggerFactory.getLogger("DebugLogger");    private static Logger errorLogger = LoggerFactory.getLogger("ErrorLogger");    　　@ResponseBody    @RequestMapping(value="/login")    public Map
     
       login(HttpServletRequest req, HttpServletResponse res){        Map
      
        response = new HashMap
       
        ();        response.put("state", "0");                String username = req.getParameter("username");        String password = req.getParameter("password");        logger.debug("登录，用户名{},密码{}", username, password);        debugLogger.debug("登录，用户名{},密码{}", username, password);        errorLogger.debug("登录，用户名{},密码{}", username, password);        if(StringUtils.isNotBlank(username)){            User user = userService.findOne(username);            if(user != null){                if(user.getPassword().equals(password)){                    response.put("state", "1");                    response.put("data", user);                }else {                    response.put("message", "账户或密码错误！");                    logger.error("账户或密码错误！");                    debugLogger.error("账户或密码错误！");                    errorLogger.error("账户或密码错误！");                }            }else {                response.put("message", "此账户不存在！");                logger.error("此账户不存在！");                errorLogger.error("此账户不存在！");            }        }else {            response.put("message", "输入有误！");            logger.error("登录出错！");            errorLogger.error("登录出错！");        }        return response;    }}
       
      
     

 

完成。
