1. 在pom中添加所需依賴

創(chuàng)建一個springboot工程，添加所需要的依賴，持久化用的是mybatis

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><!--springboot aop依賴--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency><!--mybatis--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.1.3</version></dependency><!--mysql連接--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.19</version><scope>runtime</scope></dependency><!--lombok--><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency>

2. 創(chuàng)建日志實體類

import lombok.Data;import java.io.Serializable;@Datapublic class AdminLog implements Serializable { private static final long serialVersionUID = -291495801959706565L; private Integer id; //日志記錄id private Integer userId;//操作人id private String userName;//操作人name private String loginip;//登錄ip private int type; private String url; private String operation; private String createtime; private String remark;}

3. 自定義log注解

import java.lang.annotation.*;/** * 自定義日志注解 */@Target(ElementType.METHOD) //注解防止位置@Retention(RetentionPolicy.RUNTIME)//運行時可見@Documented //生成文檔public @interface MyLog { String operation() default ''; int type();}

4. 創(chuàng)建aop切面處理類

import cn.***.springaopdemo.anno.MyLog;import cn.***.springaopdemo.dao.MyLogMapper;import cn.***.springaopdemo.pojo.Admin;import cn.***.springaopdemo.pojo.AdminLog;import org.apache.logging.log4j.LogManager;import org.apache.logging.log4j.Logger;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.aspectj.lang.reflect.MethodSignature;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes;import javax.servlet.http.HttpServletRequest;import java.lang.reflect.Method;/** * 切面處理類 */@Aspect@Componentpublic class SysLogAspect { /** * 使用log4j2把一些信息打印在控制臺上面 */ private static final Logger log = LogManager.getLogger(SysLogAspect.class); @Autowired private MyLogMapper myLogMapper; //定義切點 @Pointcut //在注解的位置切入代碼 @Pointcut('@annotation(cn.***.springaopdemo.anno.MyLog)') public void logPointCut() { } //切面 配置為前置通知 @Before('logPointCut()') public void saveOperation(JoinPoint joinPoint) { log.info('---------------接口日志記錄---------------'); //創(chuàng)建一個日志對象 AdminLog adminLog = new AdminLog(); //獲取切面織處入點的方法 MethodSignature signature = (MethodSignature) joinPoint.getSignature(); //獲取切入點所在的方法 Method method = signature.getMethod(); //獲取操作日志的屬性值 MyLog myLog = method.getAnnotation(MyLog.class); if (myLog != null) { //操作事件 String operation = myLog.operation(); adminLog.setOperation(operation); //日志類型 int type = myLog.type(); adminLog.setType(type); log.info('operation=' + operation + ',type=' + type); } //獲取url HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest(); String requestURL = request.getRequestURI().toString(); adminLog.setUrl(requestURL); //獲取客戶端ip String ip = request.getRemoteAddr(); adminLog.setLoginip(ip); //獲取操作人賬號、姓名(需要提前將用戶信息保存到Session) Admin admin = (Admin) request.getSession().getAttribute('admin'); if (admin != null) { Integer id = admin.getId(); String name = admin.getName(); adminLog.setUserId(id); adminLog.setUserName(name); } log.info('url=' + requestURL + ',ip=' + ip); //調用service保存Operation實體類到數(shù)據(jù)庫 //可以在這設置id，因為是測試，這里就使用的是數(shù)據(jù)庫的自增id myLogMapper.insertLog(adminLog); }}

5. mapper層把日志數(shù)據(jù)存儲到mysql數(shù)據(jù)庫中

mapper接口

import cn.***.springaopdemo.pojo.AdminLog;import java.util.List;public interface MyLogMapper { void insertLog(AdminLog adminLog);}

mapper.xml文件

<?xml version='1.0' encoding='UTF-8' ?><!DOCTYPE mapper PUBLIC '-//mybatis.org//DTD Mapper 3.0//EN' 'http://mybatis.org/dtd/mybatis-3-mapper.dtd'><mapper namespace='cn.***.springaopdemo.dao.MyLogMapper'> <insert parameterType='cn.***.springaopdemo.pojo.AdminLog'> INSERT INTO admin_log (user_id,user_name,loginip,type,url,operation,createtime,remark) VALUES (#{userId},#{userName},#{loginip},#{type},#{url},#{operation},now(),#{remark}) </insert></mapper>

6. 測試

先直接登錄用戶，因為是測試，直接從數(shù)據(jù)庫中獲取后登錄，把admin存儲到session中

import cn.***.springaopdemo.pojo.Admin;import cn.***.springaopdemo.service.IAdminService;import org.apache.logging.log4j.LogManager;import org.apache.logging.log4j.Logger;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import javax.servlet.http.HttpServletRequest;import java.util.List;@RestController@RequestMapping('/admin')public class AdminController { private static final Logger log = LogManager.getLogger(AdminController.class); //中間service層可以省略，直接通過mapper接口操作數(shù)據(jù)即可 @Autowired private IAdminService adminService; @RequestMapping('/login') public Admin login(HttpServletRequest request) { List<Admin> adminList = adminService.findAllAdmin(); Admin admin = adminList.get(0); request.getSession().setAttribute('admin',admin ); return admin; }}

在瀏覽器中輸入localhost:8080/admin/login，可以看到登錄的admin

進行插入和查詢操作,插入數(shù)據(jù)直接通過后臺提供

import cn.***.springaopdemo.anno.MyLog;import cn.***.springaopdemo.pojo.Type;import cn.***.springaopdemo.service.ITypeService;import org.apache.logging.log4j.LogManager;import org.apache.logging.log4j.Logger;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import java.util.ArrayList;import java.util.List;@RestController@RequestMapping('/type')public class TypeController { private static final Logger log = LogManager.getLogger(TypeController.class); @Autowired private ITypeService typeService; @MyLog(operation = '增加書籍類型', type = 2) @RequestMapping('/add') public void insertType() { List<Type> typeList = new ArrayList<>(); Type type = new Type(); type.setName('自然科學'); typeList.add(type); typeService.addTypeList(typeList); log.info('添加書籍類型' + type.getName()); } @MyLog(operation = '查詢所有書籍類型', type = 1) @RequestMapping('/findAll') public List<Type> findAllType() { List<Type> typeList = typeService.findAllType(); log.info('查詢所有書籍類型'); return typeList; }}

在瀏覽器中輸入localhost:8080/type/add，后臺日志打印記錄

再輸入查詢請求localhost:8080/type/findAll，獲得查詢出的分類

查看數(shù)據(jù)庫是否添加成功
