我正在尝试提交一个简单的登录表单，但服务器一直以“不支持请求方法‘POST’”作为警告进行响应。问题不在于表单 acion 没有响应，事实上方法响应和执行特征但无法返回结果以及我收到此警告的地方。
我已经尝试通过“RequestMethod.POST”映射 Controller 方法，但没有任何区别
Controller
@Controller
@SessionAttributes("user")
public class HomeController {
@Autowired
Iuserservice userservice;
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
/**
* Simply selects the home view to render by returning its name.
*/
@RequestMapping(value = "/", method =RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate );
USER_PARAM user = new USER_PARAM();
model.addAttribute("user", user);
return "pages/login";
}
/**
*
* @param user
* @param result
* @param status
* @return
*/
@RequestMapping(value = "/login",method = {RequestMethod.GET, RequestMethod.POST})
public String login(@ModelAttribute("user") USER_PARAM user,
BindingResult result, SessionStatus status)
{
//Validation code start
boolean error = false;
System.out.println(user); //Verifying if information is same as input by user
//on verifie est ce que les champs sont pas vide
//user name
if(user.getUSER_NAME().isEmpty()){
result.rejectValue("USER NAME", "error.USER_NAME");
error = true;
}
// user password
if(user.getUSER_PASSWORD().isEmpty()){
result.rejectValue("USER PASSWORD", "error.USER_PASSWORD");
error = true;
}
// si error est true: on renvoie vers la page login avec des message d'erreur
if(error) return "pages/login";
// si un enregistrement identique est deja presen : on renvoie vers la page login avec des message d'erreur
if (userservice.login(user)==null) return "pages/login";
// si l'aithentification a marcher : on renvoie vers la page index
else {
System.out.println("------------154");
return "index";
}
}
}

我在导航器中得到的响应
最佳答案
在您的情况下，很明显您应该将 login 方法一分为二。其中一个应该使用 RequestMethod.POST，另一个使用 RequestMethod.GET。您的解决方案可能会导致意外行为，最好单独编写它
关于java - org.springframework.web.servlet.PageNotFound - 不支持请求方法 'POST'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57180734/
