springboot使用spring的aop功能实现操作日志功能

1. 在pom中添加所需依赖
创建一个springboot工程，添加所需要的依赖，持久化用的是mybatis

                <dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<!--springboot aop依赖-->
		<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连接-->
		<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. 创建日志实体类

import lombok.Data;

import java.io.Serializable;

@Data
public class AdminLog implements Serializable {

    private static final long serialVersionUID = -291495801959706565L;

    private Integer id; //日志记录id
    private Integer userId;//操作人id
    private String userName;//操作人name
    private String loginip;//登录ip
    private int type;
    private String url;
    private String operation;
    private String createtime;
    private String remark;

}

3. 自定义log注解

import java.lang.annotation.*;

/**
 * 自定义日志注解
 */
@Target(ElementType.METHOD) //注解防止位置
@Retention(RetentionPolicy.RUNTIME)//运行时可见
@Documented //生成文档
public @interface MyLog {
    String operation() default "";

    int type();
}

4. 创建aop切面处理类

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;

/**
 * 切面处理类
 */
@Aspect
@Component
public class SysLogAspect {
    /**
     * 使用log4j2把一些信息打印在控制台上面
     */
    private static final Logger log = LogManager.getLogger(SysLogAspect.class);

    @Autowired
    private MyLogMapper myLogMapper;

    //定义切点 @Pointcut
    //在注解的位置切入代码
    @Pointcut("@annotation(cn.***.springaopdemo.anno.MyLog)")
    public void logPointCut() {

    }

    //切面 配置为前置通知
    @Before("logPointCut()")
    public void saveOperation(JoinPoint joinPoint) {
        log.info("---------------接口日志记录---------------");
        //创建一个日志对象
        AdminLog adminLog = new AdminLog();
        //获取切面织处入点的方法
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        //获取切入点所在的方法
        Method method = signature.getMethod();

        //获取操作日志的属性值
        MyLog myLog = method.getAnnotation(MyLog.class);

        if (myLog != null) {

            //操作事件
            String operation = myLog.operation();
            adminLog.setOperation(operation);

            //日志类型
            int type = myLog.type();
            adminLog.setType(type);

            log.info("operation=" + operation + ",type=" + type);
        }
        //获取url
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        String requestURL = request.getRequestURI().toString();
        adminLog.setUrl(requestURL);

        //获取客户端ip
        String ip = request.getRemoteAddr();
        adminLog.setLoginip(ip);

        //获取操作人账号、姓名(需要提前将用户信息保存到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);

        //调用service保存Operation实体类到数据库
        //可以在这设置id，因为是测试，这里就使用的是数据库的自增id
        myLogMapper.insertLog(adminLog);

    }

}

5. mapper层把日志数据存储到mysql数据库中
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 id="insertLog" 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. 测试
先直接登录用户，因为是测试，直接从数据库中获取后登录，把admin存储到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);
     //中间service层可以省略，直接通过mapper接口操作数据即可
    @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;
    }

}

在浏览器中输入localhost:8080/admin/login，可以看到登录的admin

进行插入和查询操作,插入数据直接通过后台提供

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 = "增加书籍类型", type = 2)
    @RequestMapping("/add")
    public void insertType() {
        List<Type> typeList = new ArrayList<>();
        Type type = new Type();
        type.setName("自然科学");
        typeList.add(type);
        typeService.addTypeList(typeList);
        log.info("添加书籍类型" + type.getName());
    }

    @MyLog(operation = "查询所有书籍类型", type = 1)
    @RequestMapping("/findAll")
    public List<Type> findAllType() {
        List<Type> typeList = typeService.findAllType();
        log.info("查询所有书籍类型");
        return typeList;
    }
}

在浏览器中输入localhost:8080/type/add，后台日志打印记录

再输入查询请求localhost:8080/type/findAll，获得查询出的分类

查看数据库是否添加成功
