從aop中獲取被攔截方法中的參數

@Aspect
public class CacheManager {

}

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

//從攔截的參數中獲取用戶id
private String getUserIdFromAop(JoinPoint joinPoint){
    //https://www.cnblogs.com/yln20170705/p/10511743.html

    //類名
    String clazzName = joinPoint.getTarget().getClass().getName();
    MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
    //方法名
    String methodName = methodSignature.getName();
    //參數名數組
    String[] parameters =  methodSignature.getParameterNames();
    //參數值
    Object[] args = joinPoint.getArgs();

    //獲取參數名對應數組下標
    RequestInfoDTO infoDTO = null;
    String userId = null;

    //infoDTO是被攔截的發方法的參數名，例如：plant(RequestInfoDTO infoDTO,Long cropId)
    int paramIndex = ArrayUtils.indexOf(parameters,"infoDTO"); 
    if (paramIndex != -1){
        //參數info在方法列表中，位於第一個位置
        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;
