通過攔截器記錄操作日誌，將操作日誌儲存到資料庫中，實現這個功能需要我們將curd操作的URL規範化，比如：新增是以add或者insert開始，修改是update開頭，刪除則是delete開頭。

第一步：編寫攔截器類，程式碼如下：

package com.siweisoft.interceptor;


import com.siweisoft.dao.OperationRecordMapper;
import com.siweisoft.model.OperationRecord;
import com.siweisoft.model.User;
import org.slf4j.Logger;
import
 
 org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import
 
 java.util.Date;

/**
 * 操作日誌的攔截器
 * Created by Robin on 2017-08-08.
 */
public class OperationRecordInterceptor implements HandlerInterceptor{
    protected static final Logger log = LoggerFactory.getLogger(OperationRecordInterceptor.class);

    @Autowired
    private OperationRecordMapper operationRecordMapper;

    @Override
 

    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        return true;
    }


    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {

    }
    /**
     * 方法執行後攔截
     * 用來記錄所有請求中的操作日誌
     * @param request
     * @param response
     * @param handler
     * @return
     * @throws Exception
     */
    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
        //相對路徑 /tongche/metadata/all
        String url = request.getRequestURI();
        //請求方式 POST
        String method = request.getMethod();
        String[] urlArray = url.split("/");
        if(urlArray.length>3){
            //判斷是否是增加操作
            if("add".equalsIgnoreCase(urlArray[3].substring(0,3))||("ins".equalsIgnoreCase(urlArray[3].substring(0,3)))&&("POST".equalsIgnoreCase(method))){
                addOperation(request,"ADD",urlArray[2],0);
            }
            //判斷是否是刪除操作
            if("del".equalsIgnoreCase(urlArray[3].substring(0,3))&&("POST".equalsIgnoreCase(method))){
                //當前操作的物件的ID
                int id = (int)request.getAttribute("id");
                addOperation(request,"DELETE",urlArray[2],id);
            }
            //判斷是否是修改操作
            if("upd".equalsIgnoreCase(urlArray[3].substring(0,3))&&("POST".equalsIgnoreCase(method))){
                addOperation(request,"UPDATE",urlArray[2],0);
            }
        }else{
            log.info("不合法的URL："+url);
        }
    }

    /**
     * 向操作日誌中增加資料的方法
     * @param request
     * @param operate  操作
     * @param operateObject  操作物件
     */
    public void addOperation(HttpServletRequest request, String operate, String operateObject,int id){
        //構造操作日誌物件
        OperationRecord operationRecord = new OperationRecord();
        User user = (User) request.getSession().getAttribute("user");
        operationRecord.setOperateObject(operateObject);
        operationRecord.setOperate(operate);
        operationRecord.setUserId(user.getId());
        operationRecord.setOperateTime(new Date());
        operationRecord.setOperateState(1);
        if(id>0){
            operationRecord.setOperateObjectKey(id);
        }
        operationRecordMapper.insertSelective(operationRecord);
        log.info("新增操作日誌成功！");
    }
}

第二步：配置攔截器，程式碼如下：

    <!--日誌攔截器-->
    <mvc:interceptor>
        <mvc:mapping path="/**" />
        <!-- 需排除攔截的地址 -->
        <mvc:exclude-mapping path="/login.jsp"/>
        <!--<mvc:exclude-mapping path="/user/getUserInfo"/>-->
        <mvc:exclude-mapping path="/user/pcLogin"/>
        <bean class="com.siweisoft.interceptor.OperationRecordInterceptor"></bean>
    </mvc:interceptor>

這樣就可以把簡單的curd的操作記錄到資料庫中。
