Tomcat 8.5：所需的字符串参数“ ...”不存在

从Tomcat 7.0.50升级到Tomcat 8.5.15的过程中，它停止识别我的方法之一的POST参数之一：我得到的不是正常响应，而是此消息

HTTP状态[400] – [错误请求]

类型状态报告

消息必需的字符串参数“密码”不存在

描述由于某些东西被认为是客户端错误（例如，格式不正确的请求语法，无效的请求消息框架或欺骗性的请求路由），服务器无法或不会处理请求。

Apache Tomcat / 8.5.15

方法签名为：

@RequestMapping(value = "/login", method = RequestMethod.POST)
@ResponseBody
public Map<String, Object> login(
    @RequestParam("password") String passwordHash,
    @RequestParam("username") String loginName,
    @RequestParam(value = "clientId", required = false) String clientId,
    HttpServletRequest request,
    HttpServletResponse response)
    throws NoSuchAlgorithmException {//...

我已经从请求中捕获了流量，并且您可以看到，passwordPOST参数包含在POSTx-www-form-urlencoded参数中：

奇怪的是，它在Tomcat 7下完美运行

如何提供帮助？
