spring 的AOP是通过cglib动态代理和jdk的动态代理实现的。

先把我的打印日志代码贴出来

	}

	public void methodBefore(JoinPoint joinPoint, String uuid) {

测试

请求参数类型1

	@RequestMapping(value = "/test0", method = RequestMethod.GET, produces = { MediaType.APPLICATION_JSON_VALUE })
	public Result test0(@RequestParam String name, @RequestParam String password) {
		System.out.println("test0 OK");
		return new Result("1", "mock a Result");

	}

打印日志：

参数:{"password":"123","name":"zhang"}

请求参数类型2

	@RequestMapping(value = "/test1", method = RequestMethod.GET, produces = { MediaType.APPLICATION_JSON_VALUE })
	public Result test1(PayDTO payDTO) {
		System.out.println("test1 OK");
		return new Result("1", "mock a Result");

	}

请求参数类型3

	@RequestMapping(value = "/test2", method = RequestMethod.POST, produces = { MediaType.APPLICATION_JSON_VALUE })
	public Result test2(@RequestBody PayDTO payDTO) {
		System.out.println("test2 OK");
		return new Result("2", "mock a Result");

	}
