Spring AOP 中 JoinPoint 使用详解

Object[] args = joinPoint.getArgs();
System.out.println(JSON.toJSONString(args));

String className = joinPoint.getTarget().getClass().getName();
String methodName = joinPoint.getSignature().getName();

System.out.println(className + "." + methodName);

MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();

@PostMapping("/order/create")
@RepeatSubmit(interval = 5000)
public R createOrder(@RequestBody OrderDTO dto) {
    return R.ok();
}

RepeatSubmit repeatSubmit = method.getAnnotation(RepeatSubmit.class);
int interval = repeatSubmit.interval();

@Before("@annotation(repeatSubmit)")
public void before(JoinPoint joinPoint, RepeatSubmit repeatSubmit) {

    // 获取 URI
    HttpServletRequest request =
        ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
    String uri = request.getRequestURI();

    // 获取参数
    String params = JSON.toJSONString(joinPoint.getArgs());

    // 获取方法本体
    MethodSignature signature = (MethodSignature) joinPoint.getSignature();
    Method method = signature.getMethod();

    // 获取注解内容
    RepeatSubmit anno = method.getAnnotation(RepeatSubmit.class);
    long interval = anno.interval();

    System.out.println("访问接口：" + uri);
    System.out.println("参数：" + params);
    System.out.println("注解配置间隔：" + interval + " ms");
}
