Error during execution of processor 'org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor' (template: "index" - line 93, col 69)
问题
以下是您提供的内容的翻译：
我在主页上有一个注册表单，但当我试图加载主页时出现错误。
在处理器 'org.thymeleaf.spring5.processor.SpringInputGeneralFieldTagProcessor' (模板："index" - 第93行，第69列) 执行期间发生错误。
以下是我的表单。
<form method="post" th:action="@{/register}" th:object="${registerRequestModel}">
<div class="md-form">
<i class="fas fa-user prefix white-text active"></i>
<input type="text" id="form3" name="name" th:field="*{name}" class="white-text form-control">
<label for="form3" class="active">Your name</label>
</div>
<div class="md-form">
<i class="fas fa-envelope prefix white-text active"></i>
<input type="email" id="form2" name="email" th:field="*{email}" class="white-text form-control">
<label for="form2" class="active">Your email</label>
</div>
<div class="md-form">
<i class="fas fa-lock prefix white-text active"></i>
<input type="password" id="form4" name="password" th:field="*{password}" class="white-text form-control">
<label for="form4">Your password</label>
</div>
<div class="text-center mt-4">
<button type="submit" class="btn btn-indigo">Sign up</button>
</div>
</form>
我的控制器。
@RestController
public class RequestHandler {
private AbstractRepository service;
@Autowired
public RequestHandler(AbstractRepository service) {
this.service=service;
}
@GetMapping("/")
public ModelAndView home(ModelAndView mv) {
mv.addObject("registerRequestModel", new RegisterRequestModel());
mv.setViewName("index");
return mv;
}
@PostMapping("/register")
public String registerUser(RegisterRequestModel registerRequestModel) {
service.registerCollaborators(registerRequestModel);
return "User Registered";
}
}
当我在 localhost:8080 上运行此应用程序时，会出现上述错误。当我移除 th:field="*{name}" 后，它正常工作。
以下是我的模型类。我几乎尝试了所有方法，但它不起作用。
public class RegisterRequestModel {
private String name;
private String email;
private String password;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Override
public String toString() {
return "RegisterRequestModel [name=" + name + ", email=" + email + ", password=" + password + "]";
}
}
以下是所请求的完整堆栈跟踪。

I have a register form on homepage and when I am trying to load up the home page I get the error.

Here is my form.

My Controller.

}
}
When I run this application on localhost:8080 Then it gives the above error. When I remove th:field="*{name}" then it works perfectly
Here is my model class. I have almost tried everything but it doesn't work
public class RegisterRequestModel {
private String name;
private String email;
private String password;
public String getName() {
return name;

public void setName(String name) {

}
@Override

你忘记了@ModelAttribute注解。将你的@PostMapping方法修改为以下形式：
@PostMapping("/register")
public String registerUser(@ModelAttribute RegisterRequestModel registerRequestModel) {
// service.registerCollaborators(registerRequestModel); 这段代码是做什么的？
return view; // 在这里你应该返回一个模板的名称。
}
英文:
You forgot the @ModelAttribute annotation. Make your @PostMapping method read like this:
@PostMapping("/register")
public String registerUser(@ModelAttribute RegisterRequestModel registerRequestModel) {
// service.registerCollaborators(registerRequestModel); what does this do?
return view; // you should return the name of a template here.
}

从您的代码中的这一行开始：
<input type="text" id="form3" name="name" th:field="*{name}" class="white-text form-control">
特别是 th:field="*{name}" 部分是导致错误的原因。我曾遇到类似的问题，将其中的 th 删除后问题得到解决。
英文:
From this line of your code:
<input type="text" id="form3" name="name" th:field="*{name}" class="white-text form-control">
specifically the th:field="*{name}"is what is causing the error. I had a similar problem and i remove the thfrom it and it worked.
