spring aop自定义切面打印入参和出参,以及切面获取注解的字段值.

controller代码

    @ApiOperation(value = "检查是否有兑换次数", response = Boolean.class)
    @ApiImplicitParam(name = "userId", value = "用户id", required = true)
    @GetMapping("/checkExchange")
    public R checkExchange(Long userId) {
        return emptyBottleOrderService.checkExchange(userId);
    }

切面代码 @annotation(apiOperation)的apiOperation对应的是方法的参数

package com.ruoyi.framework.aspectj;

import cn.hutool.json.JSONUtil;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;

import java.lang.reflect.Method;


@Slf4j
@Aspect
@Component
public class ApiLogAspect {

    
    @Pointcut("@annotation(io.swagger.annotations.ApiOperation)")
    public void api() {
    }

    
    @Around("api()&& @annotation(apiOperation)")
    public Object doAround(ProceedingJoinPoint joinPoint, ApiOperation apiOperation) throws Throwable {
        long startTime = System.currentTimeMillis();
        Object proceed = joinPoint.proceed();
        log.info(apiOperation.value() + "：结束：耗时{}毫秒：返回值：{}。", System.currentTimeMillis() - startTime, JSONUtil.toJsonStr(proceed));
        return proceed;
    }

    
    @Before("api()&& @annotation(apiOperation)")
    public void doBefore(JoinPoint joinPoint, ApiOperation apiOperation) throws Throwable {
//        如果你想获取其他注解可以使用一下方法获取,例如我的controller有@ApiImplicitParam

        log.info(apiOperation.value() + "：开始：参数：{}。", JSONUtil.toJsonStr(joinPoint.getArgs()));
    }

    
    @After("api()")
    public void doAfter() {
    }
}
