注解切面保存日志

1.创建自定义注解

@Target(ElementType.METHOD) 
@Retention(RetentionPolicy.RUNTIME) 
@Documented 
public @interface SysLog { 
 
	String value() default ""; 
} 

2.切面处理类(落库日志)

/** 
 * 系统日志，切面处理类 
 * 
 */ 
@Aspect 
@Component 
public class SysLogAspect { 
	@Autowired 
	private SupLogService supLogService; 
 
	@Pointcut("@annotation(bw.yth.svc.common.annotation.SysLog)") 
	public void logPointCut() { 
 
	} 
 
	@Around("logPointCut()") 
	public Object around(ProceedingJoinPoint point) throws Throwable { 
		long beginTime = System.currentTimeMillis(); 
		// 执行方法 
		Object result = point.proceed(); 
		// 执行时长(毫秒) 
		long time = System.currentTimeMillis() - beginTime; 
 
		// 保存日志 
		saveSysLog(point, time); 
 
		return result; 
	} 
 
	private void saveSysLog(ProceedingJoinPoint joinPoint, long time) { 
		ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes(); 
		HttpServletRequest request = attributes.getRequest(); 
		// 获取用户信息 
		String token = request.getHeader(AppConst.HEADER_TOKEN); 
		SessionData session = AppBuffer.bufSession.getSession(token); 
 
		MethodSignature signature = (MethodSignature) joinPoint.getSignature(); 
		Method method = signature.getMethod(); 
		SupLogPO supLog = new SupLogPO(); 
		SysLog syslog = method.getAnnotation(SysLog.class); 
		if (syslog != null) { 
			// 注解上的描述 
			supLog.setOperation(syslog.value()); 
		} 
 
		// 请求的方法名 
		String className = joinPoint.getTarget().getClass().getName(); 
		String methodName = signature.getName(); 
		supLog.setMethod(className + "." + methodName + "()"); 
 
		// 请求的参数 
		Object[] args = joinPoint.getArgs(); 
		try { 
			String params = JSONObject.toJSONString(args); 
			supLog.setParam(params); 
		} catch (Exception e) { 
 
		} 
		long userId = 0; 
		if (session != null) { 
			SysUserPO user = session.getUser(); 
			userId = user.getUserId(); 
			// 设置IP地址 
			supLog.setIp(session.getClientIp()); 
			// 客户端系统 
			EnClientSystem clientSystem = session.getClientSystem(); 
			supLog.setClientType(clientSystem.id()); 
			// 业务系统 
			EnSvcSystem svcSystem = session.getSvcSystem(); 
			supLog.setSysId(svcSystem.id()); 
		} 
		// 用户id 
		supLog.setUserId(userId); 
		// 保存系统日志 
		supLogService.save(supLog); 
	} 
} 

3.controller方法加注解

	@SysLog("测试时间格式化") 
	@PostMapping("/testDate") 
	@ApiOperation(value="测试时间格式化", notes="") 
	public TestResVo login2(@RequestBody TestReqVo req) 
	{ 
		System.out.println(JSONObject.toJSONString(req)); 
		LocalDateTime date = req.getDate(); 
		LocalDateTime plusHours = date.plusHours(2); 
		TestResVo resVo = new TestResVo(); 
		resVo.setDate(plusHours); 
		resVo.setId(18); 
		return resVo; 
	}
