SpringBoot使用AOP获取请求参数

　　最近试了下拦截controller方法查看请求参数，方式如下：

package com.*.aop;

import com.alibaba.fastjson.JSON;

import com.alibaba.fastjson.JSONArray;

import com.alibaba.fastjson.JSONObject;

import lombok.extern.slf4j.Slf4j;

import org.aspectj.lang.ProceedingJoinPoint;

import org.aspectj.lang.Signature;

import org.aspectj.lang.annotation.Around;

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.Pointcut;

import org.springframework.stereotype.Component;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.util.ArrayList;

import java.util.List;

/**

 * @Description //请求参数aop

 **/

@Component

@Aspect

@Slf4j

public class RequestParameterAop {

    /**

     * @Description: 定义需要拦截的切面

     * @Return: void

     **/

    @Pointcut("execution(* com.*.controller.*Controller.*(..))")

    public void methodArgs() {

    }

    @Around("methodArgs()")

    public Object invoke(ProceedingJoinPoint joinPoint) throws Throwable {

        Object result = null;

        Signature signature = joinPoint.getSignature();

        // 方法名

        String methodName = signature.getName();

        // 类名

        String serviceName = signature.getDeclaringTypeName();

        // 参数名数组

        String[] parameterNames = ((MethodSignature) signature).getParameterNames();

        // 构造参数组集合

        List<Object> argList = new ArrayList<>();

        for (Object arg : joinPoint.getArgs()) {

            // request/response无法使用toJSON

            if (arg instanceof HttpServletRequest) {

                argList.add("request");

            } else if (arg instanceof HttpServletResponse) {

                argList.add("response");

            } else {

                argList.add(JSON.toJSON(arg));

            }

        }

        try {

            log.info("{} -> 方法({}) -> 参数:{} - {}", serviceName, methodName, JSON.toJSON(parameterNames), JSON.toJSON(argList));

        } catch (Exception e) {

            log.error("参数获取失败: {}", e.getMessage());

        }

        result = joinPoint.proceed();

        return result;

    }

}
