请求参数中的特殊字符

Question

在我的基于REST的API（spring boot＆amp; REST）中，我的GET调用有以下参数

@RequestParam(required = false ) String name, @RequestParam(required = false, defaultValue = "1") Long page,
            @RequestParam(required = false, defaultValue = "20") Long pageSize.

当用户使用某些特殊字符调用我的GET方法时，发生错误。

请求格式如下：

http://localhost:8015/accounts/1/things/?name=%23%$25%2$3%5e

在我的控制器中，有时名称为空，有时我会收到以下错误
