Spring MVC的空模型

我有一个小thymeleaf形式访问的StdUser 某些领域这是怎样的形式创建：Spring MVC的空模型

@GetMapping("UserForm") 
public String getForm(Model model) { 
    // TODO secure 
    Authentication auth = SecurityContextHolder.getContext().getAuthentication(); 
    StdUser user = userService.getUserByMailAdress(auth.getName()); 
    model.addAttribute("user", user); 
    return "userForm"; 
}

能正常工作。下一步：用户编辑FORMDATA并将其发布

@PostMapping("foundation/UserForm") 
public String submit(@ModelAttribute @Validated(UIValidation.class) StdUser user, BindingResult bindingResult) { 
    if (bindingResult.hasErrors()) { 
     return "userForm"; 
    } 
    // TODO save 
    return "result"; 
}

这不。如果存在BeanValidationError，我想再次显示StdUser的对象以使用户有机会再次更改它。那就是return "userForm";一行。

但此时会有一个例外

我明白thymeleaf用来建立HTML的模型不包含已通过相应的postrequest发送到应用程序的StdUser对象。但为什么？？

我会很高兴的任何帮助。

编辑1 我试过同样没有弹簧安全，它的工作。这似乎是再次安慰与安全困境。

这是我SecurityConfig

@Configuration 
@EnableWebSecurity 
public class WebSecurityConfig extends WebSecurityConfigurerAdapter { 

@Autowired 
private CustomAuthenticationProvider customAuthenticationProvider; 


@Override 
protected void configure(HttpSecurity http) throws Exception { 
    http.authorizeRequests() 
    .antMatchers("/", "/index","/foundation/CompanyForm").permitAll(); 
    http.authorizeRequests().anyRequest().authenticated().and().formLogin().loginPage("/login").permitAll().and().logout().permitAll(); 
} 

@SuppressWarnings("javadoc") 
@Autowired 
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 
    auth.authenticationProvider(this.customAuthenticationProvider); 
} 
}

希望你能帮助我改变我的配置，使其重新工作。

在哪里配置XML？注释配置？ – developer

@javaguy添加它，希望这就是你一直在问 –

你从哪里获得的StdUser对象GET方法时，你不？使用Spring Security在这种情况下，你不能从'SecurityContextHolder' – jlumietu

解决它在我自己做的。问题是。 @ModelAttribute @Validated(UIValidation.class) StdUser user包含在响应的Model中，但它不使用我在GET-Methode中使用的相同名称。（"user“) it uses the Standardname which is the decapitalized Classname stdUser`。

我想你应该通过模型的StdUser对象返回到视图，完全按照你的get方法

@PostMapping("foundation/UserForm") 
public String submit(@ModelAttribute @Validated(UIValidation.class) StdUser user, BindingResult bindingResult, ModelMap model) { 
    if (bindingResult.hasErrors()) { 
     model.addAttribute("user", user); 
     return "userForm"; 
    } 
    // TODO save 
    return "result"; 
}

我不这么认为，因为我的方式没有弹簧安全性，所以必须有更简洁的方式来做到这一点 –

这可能不是唯一的方法，但我用这种方式，即使使用弹簧安全也没问题。 – jlumietu
