操作日志详解
实体类
package com.cmfz.entity;
import lombok.Data;
import java.io.Serializable;
import java.util.Date;
@Data
public class AdminLog implements Serializable {
/* `log_id` int(11) NOT NULL AUTO_INCREMENT,
`log_date` datetime NULL DEFAULT NULL,
`admin_id` int(11) NULL DEFAULT NULL,
`log_content` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`log_type` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`log_ip` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
*/
private Integer logId;
private Date logDate;
private Integer adminId;
private String logContent;
private String logType;
private String logIp;
}
DAO中的方法
添加 批量删除 查询
package com.cmfz.dao;
import com.cmfz.entity.AdminLog;
import java.util.List;
public interface AdminLogDAO {
void insertAdminLog(AdminLog adminLog);
void deleteAdminLogAll(Integer[] ids);
List selectAdminLog();
}
Mapper.xml文件中的方法
insert into cmfz_admin_log values(default,#{logDate},#{adminId},#{logContent},#{logType},#{logIp})
delete from cmfz_admin_log where log_id in
#{logId}
select * from cmfz_admin_log
service接口
package com.cmfz.service;
import com.cmfz.entity.AdminLog;
import com.github.pagehelper.PageInfo;
public interface AdminLogService {
void deleteAdminLogAll(Integer[] ids);
PageInfo selectAdminLog(Integer page, Integer limit);
}
serviceImpl 实现类
package com.cmfz.service.impl;
import com.cmfz.dao.AdminLogDAO;
import com.cmfz.entity.AdminLog;
import com.cmfz.service.AdminLogService;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service
@Transactional
public class AdminLogServiceImpl implements AdminLogService {
@Autowired
private AdminLogDAO adminLogDAO;
@Override
public void deleteAdminLogAll(Integer[] ids) {
adminLogDAO.deleteAdminLogAll(ids);
}
@Override
@Transactional(readOnly = true)
public PageInfo selectAdminLog(Integer page, Integer limit) {
PageHelper.startPage(page, limit);
return new PageInfo<>(adminLogDAO.selectAdminLog());
}
}
Controller 控制器
package com.cmfz.controller;
import com.cmfz.entity.AdminLog;
import com.cmfz.service.AdminLogService;
import com.github.pagehelper.PageInfo;
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.ResponseBody;
import java.util.HashMap;
import java.util.Map;
@Controller
@RequestMapping("adminLog")
public class AdminLogController {
@Autowired
private AdminLogService adminLogService;
@ResponseBody
@RequestMapping("showAdminLog")
public Map showAdminLog(Integer page,Integer limit){
Map map = new HashMap();
PageInfo adminPageInfo = adminLogService.selectAdminLog(page, limit);
map.put("code", 0);
map.put("msg", "");
map.put("count", adminPageInfo.getTotal());
map.put("data", adminPageInfo.getList());
return map;
}
@ResponseBody
@RequestMapping("deleteAdminLog")
public Map deleteAdminLog(Integer[] ids){
Map map = new HashMap();
try{
map.put("isDelAll", true);
adminLogService.deleteAdminLogAll(ids);
}catch (Exception e){
e.printStackTrace();
map.put("isDelAll", false);
}
return map;
}
}
重点来了
操作日志实现重点
自定义注解类
package com.cmfz.annotation;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface LogAnnotation {
String content() default "";
String type() default "select";
}
增强类(额外功能类) 中含 日志添加到数据库功能
package com.cmfz.aspect;
import com.cmfz.annotation.LogAnnotation;
import com.cmfz.dao.AdminLogDAO;
import com.cmfz.entity.Admin;
import com.cmfz.entity.AdminLog;
import com.cmfz.util.IPKit;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.After;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.lang.reflect.Method;
import java.util.Date;
@Configuration //声明当前类为配置类,相当于xml文件
@Aspect
public class LogAop {
@Autowired
private AdminLogDAO adminLogDAO;
/*
* 创建切入点
* 创建增强
*
* 织入
* */
//切入点
@Pointcut("@annotation(com.cmfz.annotation.LogAnnotation)")
public void PointCut(){}
// 日志 后置增强
//参数为切入点的名字
//ProceedingJoinPoint 连接点对象,切点对象,(包含切点附近所有的内容) 目标方法
@After("PointCut()")
public void logAfter(JoinPoint joinPoint){
//获取日志数据
//创建对象
AdminLog adminLog = new AdminLog();
//-----------------------------------------------------------获取时间-------------
//获取时间
adminLog.setLogDate(new Date());
//-----------------------------------------------------------获取Id----------------
//获取Id
ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
//获取Request
HttpServletRequest request = requestAttributes.getRequest();
//获取Session
HttpSession session = request.getSession();
//从session中获取数据
Admin admin = (Admin) session.getAttribute("admin");
if(admin != null){
adminLog.setAdminId(admin.getId());
//---------------------------------------------------------------获取ip-------------
//获取ip
adminLog.setLogIp(IPKit.getIpAddrByRequest(request));
//---------------------------------------------------------------获取方法上注解的内容-------------
//获取方法的签名对象
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
//获取方法对象
Method method = signature.getMethod();
//获取方法上的注解
LogAnnotation annotation = method.getAnnotation(LogAnnotation.class);
//把注解上的值存入日志表中
adminLog.setLogType(annotation.type());
adminLog.setLogContent(annotation.content());
//---------------------------------------------------------------添加到数据库-------------
//添加到数据库
adminLogDAO.insertAdminLog(adminLog);
}else {
System.out.println("admin为空");
}
}
}
在登陆方法上添加注解
@LogAnnotation(content = "管理员登陆",type = "login")
例:
@Controller
@RequestMapping("/admin")
public class AdminController {
@Autowired
private AdminService adminService;
@RequestMapping("/login")
@LogAnnotation(content = "管理员登陆",type = "login")
public String loginAdmin(String code, String username, String password){
Session session = SecurityUtils.getSubject().getSession();
ICaptcha iCaptcha = (ICaptcha) session.getAttribute("iCaptcha");
if(!iCaptcha.verify(code)){
return "login";
}else {
try{
// 1.将页面输入的账号密码封装到令牌中
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
// 2.获取主体 调用主体的login方法
Subject subject = SecurityUtils.getSubject();
subject.login(token);
return "main";
}catch (Exception e){
return "login";
}
}
}
