      一、前言

      我们在企业级的开发中,必不可少的是对日志的记录,实现有很多种方式,常见的就是基于AOP+注解进行保存,同时考虑到程序的流畅和效率,我们可以使用异步进行保存!

      二、基础环境

      1. 导入依赖

      我这里的springboot版本是:2.7.4

      <?XML version="1.0" encoding="UTF-8"?>

      </project>
      

      2. 编写yml配置

      server:

        port: 8080

      spring:

        datasource:

          driver-class-name: com.mysql.cj.jdbc.Driver

          url: jdbc:mysql://localhost:3306/admin?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai

          username: root

          password: 123456

          druid:

            initial-size: 5

            max-active: 100

            min-idle: 5

            max-wait: 60000

            time-between-eviction-runs-millis: 60000

            min-evictable-idle-time-millis: 30000

            validation-query: SELECT 1 FROM DUAL

            test-while-idle: true

            test-on-borrow: true

            test-on-return: false

      三、数据库设计

      数据库保存日志表的设计,这里一切从简,一般日志多的后期会进行分库分表,或者搭配ELK进行分析,分库分表一般采用根据方法类型!

      DROP TABLE IF EX编程客栈ISTS `sys_log`;
      CREATE TABLE `sys_log`  (
        `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '日志主键',
        `title` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '模块标题',
        `business_type` int(2) NULL DEFAULT 0 COMMENT '业务类型(0其它 1新增 2修改 3删除)',
        `method` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '方法名称',
        `request_method` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '请求方式',
        `oper_name` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '操作人员',
        `oper_url` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '请求URL',
        `oper_ip` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '主机地址',
        `oper_time` datetime(0) NULL DEFAULT NULL COMMENT '操作时间',
        PRIMARY KEY (`id`) USING BTREE
      ) ENGINE = InnoDB AUTO_INCREMENT = 1585197503834284034 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '操作日志记录' ROW_FORMAT = Dynamic;
      SET FOREIGN_KEY_CHECKS = 1;
      

      实体类:

      package com.example.springbootlog.entity;
      import java.util.Date;
      import java.io.Serializable;
      import com.baomidou.mybatisplus.annotation.TableId;
      import com.baomidou.mybatisplus.annotation.TableName;
      import com.fasterxml.jackson.annotation.jsonFormat;
      import lombok.Data;
      import lombok.ToString;
      /**
       * 操作日志记录(SysLog)实体类
       *
       * @author qrxm
       * @since 2023-03-26 02:09:54
       */
      @Data
      @ToString
      @TableName("sys_log")
      public class SysLog implements Serializable {
          private static final long serialVersionUID = 811241510868515068L;
          /**
          * 日志主键
          */
          @TableId
          private Long id;
          /**
          * 模块标题
          */
          private String title;
          /**
          * 业务类型(0其它 1新增 2修改 3删除)
          */
          private Integer businessType;
          /**
          * 方法名称
          */
          private String method;
          /**
          * 请求方式
          */
          private String requestMethod;
          /**
          * 操作人员
          */
          private String operName;
          /**
          * 请求URL
          */
          private String operUrl;
          /**
          * 主机地址
          */
          private String operIp;
          /**
          * 操作时间
          */
          @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
          private Date operTime;
      }
      

      四、主要功能

      大体思路:

      • 先手写一个注解
      • 切面来进行获取要保存的数据
      • 一个发布者来发布要保存的数据
      • 一个监听者监听后保存(异步)

      完整项目架构图如下:

      SpringBoot通过自定义注解与异步来管理日志流程

      1. 编写注解

      package com.example.springbootlog.annotation;
      import com.example.springbootlog.constant.BusinessTypeEnum;
      import java.lang.annotation.*;
      /**
       * 自定义操作日志记录注解
       * @author qrxm
       */
      @Target(ElementType.METHOD) // 注解只能用于方法
      @Retention(RetentionPolicy.RUNTIME) // 修饰注解的生命周期
      @Documented
      public @interface Log {
          String value() default "";
          /**
           * 模块
           */
          String title() default "测试模块";
          /**
           * 方法名称
           */
          String method() default "测试方法";
          /**
           * 功能
           */
          BusinessTypeEnum businessType() default BusinessTypeEnum.OTHER;
      }
      

      2. 业务类型枚举

      package com.example.springbootlog.constant;
      public enum BusinessTypeEnum {
          /**
           * 其它
           */
          OTHER(0,"其它"),
          /**
           * 新增
           */
          INSERT(1,"新增"),
          /**
           * 修改
           */
          UPDATE(2,"修改"),
          /**
           * 删除
           */
          DELETE(3,"删除");
          private Integer code;
          private String message;
          BusinessTypeEnum(Integer code, String message) {
              this.code = code;
              this.message = message;
          }
          public Integer getCode() {
              return code;
          }
          public String getMessage() {
              return message;
          }
      }
      

      3. 编写切片

      这里是以切片后进行发起的,当然规范流程是要加异常后的切片,这里以最简单的进行测试哈,大家按需进行添加!!

      package com.example.springbootlog.ASPect;
      import com.example.springbootlog.annotation.Log;
      import com.example.springbootlog.entity.SysLog;
      import com.example.springbootlog.listener.EventPubListener;
      import com.example.springbootlog.utils.IpUtils;
      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.slf4j.Logger;
      import org.slf4j.LoggerFactory;
      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.util.Date;
      @Aspect
      @Component
      public class SysLogAspect {
          private final Logger logger = LoggerFactory.getLogger(SysLogAspect.class);
          @Autowired
          private EventPubListener eventPubListener;
          /**
           * 以注解所标注的方法作为切入点
           */
          @Pointcut("@annotation(com.example.springbootlog.annotation.Log)")
          public void sysLog() {}
          /**
           * 在切点之后织入
           * @throws Throwable
           */
          @After("sysLog()")
          public void doAfter(JoinPoint joinPoint) {
              Log log = ((MethodSignature) joinPoint.getSignature()).getMethod()
                      .getAnnotation(Log.class);
              ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder
                      .getRequestAttributes();
              HttpServletRequest request = attributes.getRequest();
              String method = request.getMethod();
              String url = request.getRequestURL().toString();
              String ip = IpUtils.getIpAddr(request);
              SysLog sysLog = new SysLog();
              sysLog.setBusinessType(log.businessType().getCode());
              sysLog.setTitle(log.title());
              sysLog.setMethod(log.method());
              sysLog.setRequestMethod(method);
              sysLog.setOperIp(ip);
              sysLog.setOperUrl(url);
              // 从登录中token获取登录人员信息即可
              sysLog.setOperName("我是测试人员");
              sysLog.setOperTime(new Date());
              // 发布消息
              eventPubListener.pushListener(sysLog);
              logger.info("=======日志发送成功,内容:{}",sysLog);
          }
      }
      

      4. ip工具类

      package com.example.springbootlog.utils;
      import com.baomidou.mybatisplus.core.toolkit.StringUtils;
      import javax.servlet.http.HttpServletRequest;
      public class IpUtils {
          /**
           * 获取客户端IP
           *
           * @param request 请求对象
           * @return IP地址
           */
          public static String getIpAddr(HttpServletRequest request) {
              if (request == null) {
                  return "unknown";
              }
              String ip = request.getHeader("x-forwarded-for");
              if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                  ip = request.getHeader("Proxy-Client-IP");
              }
              if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                  ip = request.getHeader("X-Forwarded-For");
              }
              if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                  ip = request.getHeader("WL-Proxy-Client-IP");
              }
              if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                  ip = request.getHeader("X-Real-IP");
              }
              if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                  ip = request.getRemoteAddr();
              }
              return "0:0:0:0:0:0:0:1".equals(ip) ? "127.0.0.1" : getMultistageReverseProxyIp(ip);
          }
      编程    /**
           * 从多级反向代理中获得第一个非unknown IP地址
           *
           * @param ip 获得的IP地址
           * @return 第一个非unknown IP地址
           */
          public static String getMultistageReverseProxyIp(String ip) {
              // 多级反向代理检测
              if (ip != null && ip.indexOf(",") > 0) {
                  final String[] ips = ip.trim().split(",");
                  for (String subIp : ips) {
                      if (false == isUnknown(subIp)) {
                          ip = subIp;
                          break;
                      }
                  }
              }
              return ip;
          }
          /**
           * 检测给定字符串是否为未知,多用于检测HTTP请求相关
           *
           * @param checkString 被检测的字符串
           * @return 是否未知
           */
          public static boolean isUnknown(String checkString) {
              return StringUtils.isBlank(checkString) || "unknown".equalsIgnoreCase(checkString);
          }
      }
      

      5. 事件发布

      事件发布是由ApplicationContext对象进行发布的,直接注入使用即可!

      使用观察者模式的目的:为了业务逻辑之间的解耦,提高可扩展性。

      这种模式在spring和springboot底层是经常出现的,大家可以去看看。

      发布者只需要关注发布消息,监听者只需要监听自己需要的,不管谁发的,符合自己监听条件即可。

      package com.example.springbootlog.listener;
      import com.example.springbootlog.entity.SysLog;
      import org.springframework.beans.factophpry.annotation.Autowired;
      import org.springframework.context.ApplicationContext;
      import org.springframework.stereotype.Component;
      @Component
      public class EventPubListener {
          @Autowired
          private ApplicationContext applicationContext;
          /**
           * 事件发布方法
           * @param sysLogEvent
           */
          public void pushListener(SysLog sysLogEvent) {
              applicationContext.publishEvent(sysLogEvent);
          }
      }

      6. 监听者

      @Async:单独开启一个新线程去保存,提高效率!

      @EventListener:监听

      package com.example.springbootlog.listener;
      import com.example.springbootlog.entity.SysLog;
      import com.example.springbootlog.service.SysLogService;
      import lombok.extern.slf4j.Slf4j;
      import org.springframework.beans.factory.annotation.Autowired;
      import org.springframework.context.event.EventListener;
      import org.springframework.scheduling.annotation.Async;
      import org.springframework.stereotype.Component;
      @Slf4j
      @Component
      public class MyEventListener {
          @Autowired
          private SysLogService sysLogService;
          // 开启异步
          @Async
          // 开启监听
          @EventListener(SysLog.class)
          public void saveSysLog(SysLog event) {
              log.info("=====即将异步保存到数据库======");
              sysLogService.saveLog(event);
          }
      }
      

      五、测试

      1. controller

      package com.example.springbootlog.controller;
      import com.example.springbootlog.annotation.Log;
      import com.example.springbootlog.constant.BusinessTypeEnum;
      import lombok.extern.slf4j.Slf4j;
      import org.springframework.web.bind.annotation.*;
      /**
       * 操作日志记录(SysLog)表控制层
       *
       */
      @Slf4j
      @RestController
      @RequestMapping("sysLog")
      public class SysLogController {
          @Log(method = "测试添加方法", title = "测试呢", businessType = BusinessTypeEnum.INSERT)
          @GetMapping("/saveLog")
          public void saveLog() {
              log.info("我就是来测试一下是否成功!");
          }
      }
      

      2. service

      package com.example.springbootlog.service;
      import com.example.springbootlog.entity.SysLog;
      import com.baomidou.mybatisplus.extension.service.IService;
      /**
       * 操作日志记录(SysLog)表服务接口
       */
      public interface SysLogService  extends IService<SysLog> {
          Integer saveLog(SysLog sysLog);
      }
      
      package com.example.springbootlog.service.impl;
      import com.example.springbootlog.entity.SysLog;
      import com.example.springbootlog.service.SysLogService;
      import com.example.springbootlog.dao.SysLogDao;
      import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
      import org.springframework.beans.factory.annotation.Autowired;
      import org.springframework.stereotype.Service;
      /**
       * 操作日志记录(SysLog)表服务实现类
       */
      @Service("sysLogService")
      public class SysLogServiceImpl  extends ServiceImpl<SysLogDao, SysLog>  implements SysLogService {
          @Autowired
          private SysLogDao sysLogDao;
          @Override
          public Integer saveLog(SysLog sysLog) {
            编程客栈  return sysLogDao.insert(sysLog);
          }
      }
      

      3. dao

      这里使用mybatis-plus进行保存

      package com.example.springbootlog.dao;
      import com.example.springbootlog.entity.SysLog;
      import com.baomidou.mybatisplus.core.mapper.BaseMapper;
      /**
       * 操作日志记录(SysLog)表数据库访问层
       */
      public interface SysLogDao extends BaseMapper<SysLog> {
      }
      

      4. 测试

      访问地址:http://localhost:8080/sysLog/saveLog

      六、总结

      这个实战在企业级必不可少的,每个项目搭建人不同,但是结果都是一样的,保存日志到数据,这样可以进行按钮的点击进行统计,分析那个功能是否经常使用,那些东西需要优化。只要是有数据的东西,分析一下总会有收获的!后面日志多了就行分库分表,ELK搭建。
