Spring中通过AOP如何实现操作日志记录功能？

1. 在pom.xml中添加所需依赖，创建一个Spring Boot项目，并引入必要的依赖： - `groupId`: org.springframework.boot - `artifactId`: spring-boot-starter-web - 持久化使用：mybatis

xml org.springframework.boot spring-boot-starter-web

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.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
