org.springframework.web.servlet.PageNotFound-请求方法'POST'不支持

时间：2019-07-24 10:27:11

标签： java spring-mvc jsp tomcat

我正在尝试提交一个简单的登录表单，但服务器始终以“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，实际上方法是响应并做特征，但不能返回结果，而我得到此警告。

我已经尝试通过“ RequestMethod.POST”映射控制器方法，但没有任何区别

控制器 

@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";
                }


        }



}

1 个答案:

答案 0 :(得分：0)

对于您来说，很显然您应该将login方法一分为二。其中一个应该与RequestMethod.POST一起使用，另一个应该与RequestMethod.GET一起使用。您的解决方案可能会导致意外行为，因此，最好单独编写
