logBack的配置

新建logback.xml配置文件

驗證配置

com.imooc.o2o.web.superadmin路徑下的AreaController.java修改

package com.imooc.o2o.web.superadmin;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.imooc.o2o.entity.Area;
import com.imooc.o2o.service.AreaService;

@Controller
@RequestMapping("/superadmin")
public class AreaController {

    Logger logger = LoggerFactory.getLogger(AreaController.class);
    @Autowired
    private AreaService areaService;
    @RequestMapping(value = "/listarea",method = RequestMethod.GET)
    @ResponseBody
    private Map<String,Object> listArea(){
        logger.info("===start===");
        long startTime = System.currentTimeMillis();
        Map<String, Object> modelMap = new HashMap<String,Object>();
        List<Area> list = new ArrayList<Area>();
        try {
            list = areaService.getAreaList();
            modelMap.put("rows", list);
            modelMap.put("total", list.size());
        }catch(Exception e){
            e.printStackTrace();
            modelMap.put("success", false);
            modelMap.put("errMsg", e.toString());
        }

        logger.error("test error!");
        long endTime = System.currentTimeMillis();
        logger.debug("costTime:[{}ms]",endTime-startTime);
        logger.info("===end===");
        return modelMap;
    }

}

運行tomcat服務器

把路徑複製下來，打開文件，前往文件夾進行查看

打開鏈接http://localhost:8080/o2o/superadmin/listarea，再查看Console
