SpringBoot通過自定義注解與異步來管理日志流程
一、前言
我們在企業(yè)級的開發(fā)中,必不可少的是對日志的記錄,實現有很多種方式,常見的就是基于AOP+注解進行保存,同時考慮到程序的流暢和效率,我們可以使用異步進行保存!
二、基礎環(huán)境
1. 導入依賴
我這里的springboot版本是:2.7.4

2. 編寫yml配置
server:
port: 8080spring:
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、數據庫設計
數據庫保存日志表的設計,這里一切從簡,一般日志多的后期會進行分庫分表,或者搭配ELK進行分析,分庫分表一般采用根據方法類型!
DROP TABLE IF EXISTS `sys_log`; CREATE TABLE `sys_log` ( `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '日志主鍵', `title` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '模塊標題', `business_type` int(2) NULL DEFAULT 0 COMMENT '業(yè)務類型(0其它 1新增 2修改 3刪除)', `method` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '方法名稱', `request_method` varchar(10) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '請求方式', `oper_name` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '操作人員', `oper_url` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '請求URL', `oper_ip` varchar(128) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT '' COMMENT '主機地址', `oper_time` datetime(0) NULL DEFAULT NULL COMMENT '操作時間', PRIMARY KEY (`id`) USING BTREE ) ENGINE = InnoDB AUTO_INCREMENT = 1585197503834284034 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '操作日志記錄' ROW_FORMAT = Dynamic; SET FOREIGN_KEY_CHECKS = 1;
實體類:
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;
/**
* 操作日志記錄(SysLog)實體類
*
* @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;
/**
* 日志主鍵
*/
@TableId
private Long id;
/**
* 模塊標題
*/
private String title;
/**
* 業(yè)務類型(0其它 1新增 2修改 3刪除)
*/
private Integer businessType;
/**
* 方法名稱
*/
private String method;
/**
* 請求方式
*/
private String requestMethod;
/**
* 操作人員
*/
private String operName;
/**
* 請求URL
*/
private String operUrl;
/**
* 主機地址
*/
private String operIp;
/**
* 操作時間
*/
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private Date operTime;
}
四、主要功能
大體思路:
- 先手寫一個注解
- 切面來進行獲取要保存的數據
- 一個發(fā)布者來發(fā)布要保存的數據
- 一個監(jiān)聽者監(jiān)聽后保存(異步)
完整項目架構圖如下:

1. 編寫注解
package com.example.springbootlog.annotation;
import com.example.springbootlog.constant.BusinessTypeEnum;
import java.lang.annotation.*;
/**
* 自定義操作日志記錄注解
* @author qrxm
*/
@Target(ElementType.METHOD) // 注解只能用于方法
@Retention(RetentionPolicy.RUNTIME) // 修飾注解的生命周期
@Documented
public @interface Log {
String value() default "";
/**
* 模塊
*/
String title() default "測試模塊";
/**
* 方法名稱
*/
String method() default "測試方法";
/**
* 功能
*/
BusinessTypeEnum businessType() default BusinessTypeEnum.OTHER;
}
2. 業(yè)務類型枚舉
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"),
/**
* 刪除
*/
DELETE(3,"刪除");
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. 編寫切片
這里是以切片后進行發(fā)起的,當然規(guī)范流程是要加異常后的切片,這里以最簡單的進行測試哈,大家按需進行添加??!
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;
/**
* 以注解所標注的方法作為切入點
*/
@Pointcut("@annotation(com.example.springbootlog.annotation.Log)")
public void sysLog() {}
/**
* 在切點之后織入
* @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);
// 從登錄中token獲取登錄人員信息即可
sysLog.setOperName("我是測試人員");
sysLog.setOperTime(new Date());
// 發(fā)布消息
eventPubListener.pushListener(sysLog);
logger.info("=======日志發(fā)送成功,內容:{}",sysLog);
}
}
4. ip工具類
package com.example.springbootlog.utils;
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
import javax.servlet.http.HttpServletRequest;
public class IpUtils {
/**
* 獲取客戶端IP
*
* @param request 請求對象
* @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);
}
/**
* 從多級反向代理中獲得第一個非unknown IP地址
*
* @param ip 獲得的IP地址
* @return 第一個非unknown IP地址
*/
public static String getMultistageReverseProxyIp(String ip) {
// 多級反向代理檢測
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;
}
/**
* 檢測給定字符串是否為未知,多用于檢測HTTP請求相關
*
* @param checkString 被檢測的字符串
* @return 是否未知
*/
public static boolean isUnknown(String checkString) {
return StringUtils.isBlank(checkString) || "unknown".equalsIgnoreCase(checkString);
}
}
5. 事件發(fā)布
事件發(fā)布是由ApplicationContext對象進行發(fā)布的,直接注入使用即可!
使用觀察者模式的目的:為了業(yè)務邏輯之間的解耦,提高可擴展性。
這種模式在spring和springboot底層是經常出現的,大家可以去看看。
發(fā)布者只需要關注發(fā)布消息,監(jiān)聽者只需要監(jiān)聽自己需要的,不管誰發(fā)的,符合自己監(jiān)聽條件即可。
package com.example.springbootlog.listener;
import com.example.springbootlog.entity.SysLog;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.stereotype.Component;
@Component
public class EventPubListener {
@Autowired
private ApplicationContext applicationContext;
/**
* 事件發(fā)布方法
* @param sysLogEvent
*/
public void pushListener(SysLog sysLogEvent) {
applicationContext.publishEvent(sysLogEvent);
}
}6. 監(jiān)聽者
@Async:單獨開啟一個新線程去保存,提高效率!
@EventListener:監(jiān)聽
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;
// 開啟異步
@Async
// 開啟監(jiān)聽
@EventListener(SysLog.class)
public void saveSysLog(SysLog event) {
log.info("=====即將異步保存到數據庫======");
sysLogService.saveLog(event);
}
}
五、測試
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.*;
/**
* 操作日志記錄(SysLog)表控制層
*
*/
@Slf4j
@RestController
@RequestMapping("sysLog")
public class SysLogController {
@Log(method = "測試添加方法", title = "測試呢", businessType = BusinessTypeEnum.INSERT)
@GetMapping("/saveLog")
public void saveLog() {
log.info("我就是來測試一下是否成功!");
}
}
2. service
package com.example.springbootlog.service;
import com.example.springbootlog.entity.SysLog;
import com.baomidou.mybatisplus.extension.service.IService;
/**
* 操作日志記錄(SysLog)表服務接口
*/
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;
/**
* 操作日志記錄(SysLog)表服務實現類
*/
@Service("sysLogService")
public class SysLogServiceImpl extends ServiceImpl<SysLogDao, SysLog> implements SysLogService {
@Autowired
private SysLogDao sysLogDao;
@Override
public Integer saveLog(SysLog sysLog) {
return sysLogDao.insert(sysLog);
}
}
3. dao
這里使用mybatis-plus進行保存
package com.example.springbootlog.dao;
import com.example.springbootlog.entity.SysLog;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;
/**
* 操作日志記錄(SysLog)表數據庫訪問層
*/
public interface SysLogDao extends BaseMapper<SysLog> {
}
4. 測試
訪問地址:http://localhost:8080/sysLog/saveLog

5. 數據庫

六、總結
這個實戰(zhàn)在企業(yè)級必不可少的,每個項目搭建人不同,但是結果都是一樣的,保存日志到數據,這樣可以進行按鈕的點擊進行統(tǒng)計,分析那個功能是否經常使用,那些東西需要優(yōu)化。只要是有數據的東西,分析一下總會有收獲的!后面日志多了就行分庫分表,ELK搭建。
