利用SpringAop实现日志功能
下面将实现日志的查看，通知的记录工能。
使用技术：SM+SERVLET
1.创建日志实体类
import java.util.Date;
public class Log {
private Date oprTime; //操作时间
private String type;//系统日志，登录日志，操作日志
private String operator;//操作人员
private String moudle;//在那个部分
private String operation;//进行了什么操作
private String result;//结果
省略get（），set（）...
}
2.dao接口
import java.util.List;
@Repository("logDao")
public interface LogDao {
void insert(Log log);//插入日志
List<Log> selectByType(String type);//根据日志类型获取日志
}
3.logDao.xml
<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.4//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.mgy.dao.LogDao">
<resultMap id="resultMap" type="Log">
<result property="oprTime" column="opr_time" javaType="java.util.Date"/>
<result property="type" column="type" javaType="String"/>
<result property="operator" column="operator" javaType="String"/>
<result property="moudle" column="moudle" javaType="String"/>
<result property="operation" column="operation" javaType="String"/>
<result property="result" column="result" javaType="String"/>
</resultMap>
<insert id="insert" parameterType="Log">
insert into log values (#{oprTime},#{type},#{operator},#{moudle},#{operation},#{result})
</insert>
<select id="selectByType" parameterType="String" resultMap="resultMap">
select * from log where type = #{type} order by opr_time desc
</select>
</mapper>
4.实现logService
import com.mgy.entity.Log;
import java.util.List;
public interface LogService {
void addSystemLog(Log log);//插入系统日志
void addLoginLog(Log log);//插入登录日志
void addOperationLog(Log log);//插入操作日志
List<Log> getSystemLog();//得到系统日志
List<Log> getLoginLog();//得到登录日志
List<Log> getOperationLog();//得到操作日志
}
5.logServiceImpl
@Service("logService")
public class LogServiceImpl implements LogService {
@Resource
private LogDao logDao;
/*
*在这里将必备的时间，日志类型提前做好插入和准备。
**/
public void addSystemLog(Log log) {
log.setOprTime(new Date());
log.setType("system");
logDao.insert(log);
}
public void addLoginLog(Log log) {
log.setOprTime(new Date());
log.setType("login");
logDao.insert(log);
}
public void addOperationLog(Log log) {
log.setOprTime(new Date());
log.setType("operation");
logDao.insert(log);
}
public List<Log> getSystemLog() {
return logDao.selectByType("system");
}
public List<Log> getLoginLog() {
return logDao.selectByType("login");
}
public List<Log> getOperationLog() {
return logDao.selectByType("operation");
}
}
6.LogAdvice 切面类，用于增强方法截取用户操作过程
@Component
@Aspect
public class LogAdvice {
@Resource
private LogService logService;
/*
* 操作日志
* */
//后置增强，对controller下所有*.controller进行方法增强，排除selefcontroller与to开头的方法（使用的框架为sm+servlet）
@After("execution(* com.mgy.controller.*.*(..)) && !execution(* com.mgy.controller.SelfController.*(..)) && execution(* com.mgy.controller.*.to*(..))")
public void operationLog(JoinPoint joinPoint){//需要通过joinpoint来获取
Log log = new Log();
log.setMoudle(joinPoint.getTarget().getClass().getSimpleName());//获取类名
log.setOperation(joinPoint.getSignature().getName());//获取方法名
HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];//获取参数列表
HttpSession session = request.getSession();//将拿到的参数列表的第一个参数获取到sessiong
Object o = session.getAttribute("USER");//从session中拿出用户session
Staff staff = (Staff)o;
log.setOperator(staff.getAccount());//将session中的用户记录
log.setResult("成功");//未发生异常set成功
logService.addOperationLog(log);
}
/*
* 系统异常日志
* */
@AfterThrowing(throwing = "e",pointcut = "execution(* com.mgy.controller.*.*(..)) && !execution(* com.mgy.controller.SelfController.*(..))")
public void systemLog(JoinPoint joinPoint,Throwable e){//需要通过joinpoint来获取
Log log = new Log();
log.setMoudle(joinPoint.getTarget().getClass().getSimpleName());//获取类名
log.setOperation(joinPoint.getSignature().getName());//获取方法名
HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];//获取参数列表
HttpSession session = request.getSession();//将拿到的参数列表的第一个参数获取到sessiong
Object o = session.getAttribute("USER");//从session中拿出用户session
Staff staff = (Staff)o;
log.setOperator(staff.getAccount());//将session中的用户记录
log.setResult(e.getClass().getSimpleName());//获取发生异常的类
logService.addSystemLog(log);
}
/*
* 登陆日志
* */
@After("execution(* com.mgy.controller.SelfController.login(..))")
public void loginLog(JoinPoint joinPoint){//需要通过joinpoint来获取
Log log = new Log();
log.setMoudle(joinPoint.getTarget().getClass().getSimpleName());//获取类名
log.setOperation(joinPoint.getSignature().getName());//获取方法名
HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];//获取参数列表
HttpSession session = request.getSession();//将拿到的参数列表的第一个参数获取到sessiong
Object o = session.getAttribute("USER");//从session中拿出用户session
if (o==null){
log.setOperation(request.getParameter("account"));//如果获取不到session证明未登陆成功，此时将用户输入的用户名记录
log.setResult("失败");
}else {
// 如果session中有值代表登陆成功
Staff staff = (Staff)o;
log.setOperator(staff.getAccount());//将session中的用户记录
log.setResult("成功");
}
logService.addLoginLog(log);
}
/*
* 登出日志
* */
@Before("execution(* com.mgy.controller.SelfController.logout(..))")
public void logoutLog(JoinPoint joinPoint){//需要通过joinpoint来获取
Log log = new Log();
log.setMoudle(joinPoint.getTarget().getClass().getSimpleName());//获取类名
log.setOperation(joinPoint.getSignature().getName());//获取方法名
HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];
HttpSession session = request.getSession();
Object o = session.getAttribute("USER");
if (o==null){
log.setOperation(request.getParameter("account"));
}else {
Staff staff = (Staff)o;
log.setOperator(staff.getAccount());
log.setResult("成功");
}
logService.addLoginLog(log);
}
}
7.LogController
@Controller
public class LogController {
@Resource
private LogService logService;
public void operationLog(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
List<Log> operationLog = logService.getOperationLog();
request.setAttribute("LIST",operationLog);
request.setAttribute("TYPE","操作");//设置前台展示的日志title方便区分
request.getRequestDispatcher("/WEB-INF/page/log_list.jsp").forward(request,response);
}
public void loginLog(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
List<Log> loginLog = logService.getLoginLog();
request.setAttribute("LIST",loginLog);
request.setAttribute("TYPE","登陆");
request.getRequestDispatcher("/WEB-INF/page/log_list.jsp").forward(request,response);
}
public void systemLog(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
List<Log> systemLog = logService.getSystemLog();
request.setAttribute("LIST",systemLog);
request.setAttribute("TYPE","系统");
request.getRequestDispatcher("/WEB-INF/page/log_list.jsp").forward(request,response);
}
}
前端实现：

<div class="nav_m">
<span><a>日志信息</a></span>
<i> </i>

<div class="space_hx"> </div>
<!--列表-->
<table cellpadding="0" cellspacing="0" class="list_hy">
<tr>
<th scope="col">操作时间</th>
<th scope="col">操作人员</th>
<th scope="col">模块</th>
<th scope="col">操作</th>
<th scope="col">结果</th>
</tr>
<c:forEach items="${LIST}" var="log">
<tr>
<td><fmt:formatDate value="${log.oprTime}" pattern="yyyy-MM-dd HH:mm:ss"/></td>
<td>${log.operator}</td>
<td>${log.moudle}</td>
<td>${log.operation}</td>
<td>${log.result}</td>
