AOP实现类

@Aspect
@Configuration
@Slf4j
public class Aop {
    // 定义切点Pointcut
//    @Pointcut("execution(* com.nike.mpp.controller..*.*(..))")
    @Pointcut("@annotation(com.nike.mpp.timer.LogInfo)")
    public void executeService() {
    }

    @Around("executeService()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        RequestAttributes ra = RequestContextHolder.getRequestAttributes();
        ServletRequestAttributes sra = (ServletRequestAttributes) ra;
        HttpServletRequest request = sra.getRequest();

        String url = request.getRequestURL().toString();
        String method = request.getMethod();
        //String uri = request.getRequestURI();
        String queryString = request.getQueryString();
        Object[] args = pjp.getArgs();
        String params = "";
        //获取请求参数集合并进行遍历拼接
        if(args.length>0){
            if("POST".equals(method)){
                Object object = args[0];
                Map map = getKeyAndValue(object);
                params = JSON.toJSONString(map);
            }else if("GET".equals(method)){
                params = URLDecoder.decode(queryString,"UTF-8");
            }
        }

        log.info("————————————————————————————————————————————————————");
        log.info(getLogValue(pjp));
        log.info("请求开始===地址:"+url);
        log.info("请求开始===类型:"+method);
        log.info("请求开始===参数:"+params);

        // result的值就是被拦截方法的返回值
        Object result = pjp.proceed();
        log.info("请求结束===返回值:" + JSON.toJSON(result));
        log.info("————————————————————————————————————————————————————");
        return result;
    }

    public static Map<String, Object> getKeyAndValue(Object obj) {
        Map<String, Object> map = new HashMap<>();
        // 得到类对象
        Class userCla = obj.getClass();
        /* 得到类中的所有属性集合 */
        Field[] fs = userCla.getDeclaredFields();
        for (Field f : fs) {
            f.setAccessible(true); // 设置些属性是可以访问的
            Object val;
            try {
                val = f.get(obj);
                // 得到此属性的值
                map.put(f.getName(), val);// 设置键值
            } catch (IllegalArgumentException | IllegalAccessException e) {
                e.printStackTrace();
            }

        }
        return map;
    }

    private String getLogValue(JoinPoint joinPoint) {
        MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
        Method method = methodSignature.getMethod();

        LogInfo logInfo = method.getAnnotation(LogInfo.class);

        return logInfo.value();
    }
}

使用方式（在Controller使用该注解）

@LogInfo(value = "测试测试，查询版本")
