Thymeleaf：无法传递隐藏的th：field的预定义值

Question

有一个带有隐藏值字段的表单：

<input type = "hidden" th:field="*{key}" value="keyapp" />
<input type = "hidden" th:field="*{secret}" value="supersecret" />

问题是这些字段在控制器中作为空传递。有没有办法通过预定义的HTML值传递百万美元字段？

谢谢和亲切的问候， Deniss

更新

th:object定义：

<form th:action="@{..//do-login}" method="POST" modelAttribute="authEntity" th:object="${authEntity}">

AuthEntity类

public class AuthEntity {

    private String key;
    private String secret;
    private String scope;
    private String grantType;
    private String username;
    private String password;
    // getters & setters omitted //
}

控制器类

@RequestMapping(value = "/do-login", method = RequestMethod.POST, produces = "application/json")
public void doLogin(@ModelAttribute("authEntity") final AuthEntity authEntity,
                    final Model model, HttpServletResponse servletResponse,
                    HttpSession httpSession) throws IOException {
    log.info("Application Key: {}, Secret: {}", authEntity.getKey(), authEntity.getSecret());
}

我遇到了与隐藏输入相同的问题并找不到解决方案但是，不是使用th：field，而是手动设置字段的'id'和'name'属性并省略th：field。
