一、数据库与表结构

1、日志表信息描述sysLog

2、sql语句

CREATE TABLE sysLog(	id VARCHAR2(32) default SYS_GUID() PRIMARY KEY,	visitTime timestamp,	username VARCHAR2(50),	ip VARCHAR2(30),	url VARCHAR2(50),	executionTime int,	method VARCHAR2(200))

3、创建对应的实体类

package com.itzheng.ssm.domain;import java.util.Date;public class SysLog {
       private String id;    private Date visitTime;    private String visitTimeStr;    private String username;    private String ip;    private String url;    private Long executionTime;    private String method;    public SysLog() {
       }    public SysLog(String id, Date visitTime, String visitTimeStr, String username, String ip, String url, Long executionTime, String method) {
           this.id = id;        this.visitTime = visitTime;        this.visitTimeStr = visitTimeStr;        this.username = username;        this.ip = ip;        this.url = url;        this.executionTime = executionTime;        this.method = method;    }    public String getId() {
           return id;    }    public void setId(String id) {
           this.id = id;    }    public Date getVisitTime() {
           return visitTime;    }    public void setVisitTime(Date visitTime) {
           this.visitTime = visitTime;    }    public String getVisitTimeStr() {
           return visitTimeStr;    }    public void setVisitTimeStr(String visitTimeStr) {
           this.visitTimeStr = visitTimeStr;    }    public String getUsername() {
           return username;    }    public void setUsername(String username) {
           this.username = username;    }    public String getIp() {
           return ip;    }    public void setIp(String ip) {
           this.ip = ip;    }    public String getUrl() {
           return url;    }    public void setUrl(String url) {
           this.url = url;    }    public Long getExecutionTime() {
           return executionTime;    }    public void setExecutionTime(Long executionTime) {
           this.executionTime = executionTime;    }    public String getMethod() {
           return method;    }    public void setMethod(String method) {
           this.method = method;    }    @Override    public String toString() {
           return "SysLog{" +                "id='" + id + '\'' +                ", visitTime=" + visitTime +                ", visitTimeStr='" + visitTimeStr + '\'' +                ", username='" + username + '\'' +                ", ip='" + ip + '\'' +                ", url='" + url + '\'' +                ", executionTime=" + executionTime +                ", method='" + method + '\'' +                '}';    }}

二、基于AOP日志处理（记录日志信息）

1、在控制层创建LogAop类

        
    
     org.springframework.web.context.request.RequestContextListener
    
   

LogAop类

package com.itzheng.ssm.controller;import com.itzheng.ssm.domain.SysLog;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.security.core.context.SecurityContext;import org.springframework.security.core.context.SecurityContextHolder;import org.springframework.security.core.userdetails.User;import org.springframework.stereotype.Component;import org.springframework.web.bind.annotation.RequestMapping;import javax.servlet.http.HttpServletRequest;import java.lang.annotation.Annotation;import java.lang.reflect.Method;import java.util.Date;@Component@Aspectpublic class LogAop {
       @Autowired    private HttpServletRequest requset;    private Date visitTime;//开始的时间    private Class clazz;//访问的类    private Method method;//访问的方法    //前置通知   主要是获取我们的开始的时间，执行类的哪一个，执行的是哪一个方法    @Before("execution(* com.itzheng.ssm.controller.*.*(..))")//拦截controller类当中的所有的方法    public void doBefore(JoinPoint jp) throws NoSuchMethodException {
           visitTime = new Date();//当前时间就是开始访问的时间        clazz = jp.getTarget().getClass();//获取当前具体要访问的类        String methodName = jp.getSignature().getName();//获取当前访问具体方法的名称        Object[] args = jp.getArgs();//获取访问方法的参数        //以下代码获取到了具体执行的方法的method对象        if(args == null || args.length == 0){
               method = clazz.getMethod(methodName);//只能获取无参数的方法        }else {
               Class[] classArgs = new Class[args.length];            for (int i = 0; i < args.length;i++){
                   classArgs[i] = args[i].getClass();//获取每一个方法参数，放到classArgs数组当中            }            method = clazz.getMethod(methodName,classArgs);//只能获取无参数的方法        }    }    //后置通知    @After("execution(* com.itzheng.ssm.controller.*.*(..))")//拦截controller类当中的所有的方法    public void doAfter(JoinPoint jp){
           long time = new Date().getTime()-visitTime.getTime();//获取了访问的时长        String url = "";        //获取url        if( clazz != null && method != null && clazz != LogAop.class){
               //1.获取类上的这个注解@RequestMapping("/orders")的值            RequestMapping classAnnotation = (RequestMapping)clazz.getAnnotation(RequestMapping.class);            if(classAnnotation != null){
                   String[] classValue = classAnnotation.value();//获取到了/orders                //2、获取方法上的@RequestMapping(xxx)                RequestMapping methodAnnotation = method.getAnnotation(RequestMapping.class);                if(methodAnnotation != null){
                       String [] methodValue =  methodAnnotation.value();                    url = classValue[0] + methodValue[0];                }            }        }        //获取访问的IP地址        String ip = requset.getRemoteAddr();        //如何获取当前操作的用户        SecurityContext context = SecurityContextHolder.getContext();//从上下文当中获取当前登录的用户        User user = (User)context.getAuthentication().getPrincipal();        String username = user.getUsername();        //将日志相关信息分装到SysLog对象当中        SysLog sysLog = new SysLog();        sysLog.setExecutionTime(time);//执行时长        sysLog.setIp(ip);        sysLog.setMethod("[类名] "+clazz.getName()+"[方法名] " + method.getName());        sysLog.setUrl(url);        sysLog.setUsername(username);        sysLog.setVisitTime(visitTime);        //调用Service完成数据库的插入操作（即日志的记录操作）    }}

2、创建对应的Service接口和对应的实现类

（1）ISysLogService接口

package com.itzheng.ssm.service;import com.itzheng.ssm.domain.SysLog;public interface ISysLogService {
       public void save(SysLog sysLog) throws Exception;}

（2）SysLogServiceImpl

package com.itzheng.ssm.service.impl;import com.itzheng.ssm.domain.SysLog;import com.itzheng.ssm.service.ISysLogService;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;@Service@Transactionalpublic class SysLogServiceImpl implements ISysLogService {
       @Override    public void save(SysLog sysLog) throws Exception {
       }}

3、创建对应的DAO

package com.itzheng.ssm.dao;import com.itzheng.ssm.domain.SysLog;import org.apache.ibatis.annotations.Insert;public interface ISysLogDao {
       @Insert("")    public void save(SysLog sysLog) throws Exception ;}

4、完善上述所有的业务以及dao

（1）SysLogServiceImpl

package com.itzheng.ssm.service.impl;import com.itzheng.ssm.dao.ISysLogDao;import com.itzheng.ssm.domain.SysLog;import com.itzheng.ssm.service.ISysLogService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Transactional;@Service@Transactionalpublic class SysLogServiceImpl implements ISysLogService {
       @Autowired    private ISysLogDao sysLogDao;    @Override    public void save(SysLog sysLog) throws Exception {
           sysLogDao.save(sysLog);    }}

（2）LogAop

@Autowired    private ISysLogService sysLogService;

//调用Service完成数据库的插入操作（即日志的记录操作）        sysLogService.save(sysLog);

（3）ISysLogDao

package com.itzheng.ssm.dao;import com.itzheng.ssm.domain.SysLog;import org.apache.ibatis.annotations.Insert;public interface ISysLogDao {
       @Insert("insert into syslog(visitTime,username,ip,url,executionTime,method) values(#{visitTime},#{username},#{ip},#{url},#{executionTime},#{method})")    public void save(SysLog sysLog) throws Exception ;}

（4）完善LogAop类

package com.itzheng.ssm.controller;import com.itzheng.ssm.domain.SysLog;import com.itzheng.ssm.service.ISysLogService;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.http.HttpRequest;import org.springframework.http.server.ServletServerHttpRequest;import org.springframework.security.core.context.SecurityContext;import org.springframework.security.core.context.SecurityContextHolder;import org.springframework.security.core.userdetails.User;import org.springframework.stereotype.Component;import org.springframework.web.bind.annotation.RequestMapping;import javax.servlet.http.HttpServletRequest;import java.lang.annotation.Annotation;import java.lang.reflect.Method;import java.util.Date;@Component@Aspectpublic class LogAop {
       @Autowired    private HttpServletRequest request;    @Autowired    private ISysLogService sysLogService;    private Date visitTime; //开始时间    private Class clazz; //访问的类    private Method method;//访问的方法    //前置通知  主要是获取开始时间，执行的类是哪一个，执行的是哪一个方法    @Before("execution(* com.itzheng.ssm.controller.*.*(..))")    public void doBefore(JoinPoint jp) throws NoSuchMethodException {
           visitTime = new Date();//当前时间就是开始访问的时间        clazz = jp.getTarget().getClass(); //具体要访问的类        String methodName = jp.getSignature().getName(); //获取访问的方法的名称        Object[] args = jp.getArgs();//获取访问的方法的参数        //获取具体执行的方法的Method对象        if (args == null || args.length == 0) {
               method = clazz.getMethod(methodName); //只能获取无参数的方法        } else {
               Class[] classArgs = new Class[args.length];            for (int i = 0; i < args.length; i++) {
                   classArgs[i] = args[i].getClass();            }            clazz.getMethod(methodName, classArgs);        }    }    //后置通知    @After("execution(* com.itzheng.ssm.controller.*.*(..))")    public void doAfter(JoinPoint jp) throws Exception {
           long time = new Date().getTime() - visitTime.getTime(); //获取访问的时长        String url = "";        //获取url        if (clazz != null && method != null && clazz != LogAop.class) {
               //1.获取类上的@RequestMapping("/orders")            RequestMapping classAnnotation = (RequestMapping) clazz.getAnnotation(RequestMapping.class);            if (classAnnotation != null) {
                   String[] classValue = classAnnotation.value();                //2.获取方法上的@RequestMapping(xxx)                RequestMapping methodAnnotation = method.getAnnotation(RequestMapping.class);                if (methodAnnotation != null) {
                       String[] methodValue = methodAnnotation.value();                    url = classValue[0] + methodValue[0];                    //获取访问的ip                    String ip = request.getRemoteAddr();                    //String ip = "192.168.153.2012";                    //获取当前操作的用户                    SecurityContext context = SecurityContextHolder.getContext();//从上下文中获了当前登录的用户                    User user = (User) context.getAuthentication().getPrincipal();                    String username = user.getUsername();                    //将日志相关信息封装到SysLog对象                    SysLog sysLog = new SysLog();                    sysLog.setExecutionTime(time); //执行时长                    sysLog.setIp(ip);                    sysLog.setMethod("[类名] " + clazz.getName() + "[方法名] " + method.getName());                    sysLog.setUrl(url);                    sysLog.setUsername(username);                    sysLog.setVisitTime(visitTime);                    //调用Service完成操作                    sysLogService.save(sysLog);                }            }        }    }}

（5）修改OrdersController当中findAll方法参数

@RequestMapping("/findAll.do")    @Secured("ROLE_ADMIN")    public ModelAndView findAll(@RequestParam(name = "page", required = true, defaultValue = "1") Integer page,                                @RequestParam(name = "size", required = true, defaultValue = "4") Integer size) throws Exception {

（6）运行测试

三、基于AOP日志的查询

（1）创建syslog-list.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"	pageEncoding="UTF-8"%><%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

（2）创建SysLogController

package com.itzheng.ssm.controller;import com.itzheng.ssm.domain.SysLog;import com.itzheng.ssm.service.ISysLogService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import java.util.List;@Controller@RequestMapping("/sysLog")public class SysLogController {
       @Autowired    private ISysLogService sysLogService;    @RequestMapping("/findAll.do")    public ModelAndView findAll() throws Exception{
           ModelAndView mv = new ModelAndView();        List
   
     sysLogList = sysLogService.findAll();        return mv;    }}
   

（3）ISysLogService以及SysLogServiceImpl当中

List
   
     findAll()throws Exception;
   

@Override    public List
   
     findAll() throws Exception {
           return sysLogDao.findAll();    }
   

（4）ISysLogDao当中

@Select("select * from sysLog")    List
   
     findAll() throws Exception ;
   

（5）完善SysLogController

package com.itzheng.ssm.controller;import com.itzheng.ssm.domain.SysLog;import com.itzheng.ssm.service.ISysLogService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import java.util.List;@Controller@RequestMapping("/sysLog")public class SysLogController {
       @Autowired    private ISysLogService sysLogService;    @RequestMapping("/findAll.do")    public ModelAndView findAll() throws Exception{
           ModelAndView mv = new ModelAndView();        List
   
     sysLogList = sysLogService.findAll();        mv.addObject("sysLogs",sysLogList);        mv.setViewName("syslog-list");        return mv;    }}
   

（6）运行测试项目
