SpringAOP如何修改请求参数列表

private final String execution = "execution(* com.zxy.test.degitaltool.tree.controller.TestController.*(..))";
 
    /**
     * @param pjp
     * @return
     * @throws Throwable
     */
    @Around(execution)
    public Object before(ProceedingJoinPoint pjp) throws Throwable {
        Method method = ((MethodSignature) pjp.getSignature()).getMethod();
        Parameter[] parameters = method.getParameters();
        int keyIndex = getKeyIndex2(parameters, "treeId");
        Object[] args = pjp.getArgs();
        if (keyIndex != -1) {
            String value = args[keyIndex];//找到对应的值
            ...
        }
        return pjp.proceed(args);//修改参数值
    }
 
    private int getKeyIndex2(Parameter[] parameters, String key) {
        for (int i = 0; i < parameters.length; i++) {
            if (Objects.equals(parameters[i].getName(), key)) {
                return i;
            }
        }
        return -1;
    }
