从aop中获取被拦截方法中的参数

@Aspect
public class CacheManager {

}

@Before("execution(* com.aliexpress.social.game.cointree.cointree.gateway.application.*.*(..))")
public void migrateCheck(JoinPoint joinPoint) {
  String userId = getUserIdFromAop(jointPoint)；
}

//从拦截的参数中获取用户id
private String getUserIdFromAop(JoinPoint joinPoint){
    //https://www.cnblogs.com/yln20170705/p/10511743.html

    //类名
    String clazzName = joinPoint.getTarget().getClass().getName();
    MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
    //方法名
    String methodName = methodSignature.getName();
    //参数名数组
    String[] parameters =  methodSignature.getParameterNames();
    //参数值
    Object[] args = joinPoint.getArgs();

    //获取参数名对应数组下标
    RequestInfoDTO infoDTO = null;
    String userId = null;

    //infoDTO是被拦截的发方法的参数名，例如：plant(RequestInfoDTO infoDTO,Long cropId)
    int paramIndex = ArrayUtils.indexOf(parameters,"infoDTO"); 
    if (paramIndex != -1){
        //参数info在方法列表中，位于第一个位置
        infoDTO = (RequestInfoDTO)args[0];
        userId = infoDTO.getUserId();

    }
    log.info("getUserIdFromAop clazzName = {} methodName = {} parameters = {} args = {} userId = {} ",
        new Object[] {clazzName, methodName, JSON.toJSONString(parameters), JSON.toJSONString(args), userId});

    return userId;
