如何修复“org.springframework.web.HttpRequestMethodNotSupportedException : Request method 'POST' not supported?" [英] How to fix "org.springframework.web.HttpRequestMethodNotSupportedException : Request method 'POST' not supported ?"

问题描述

所以我收到警告

 WARN  [org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver] (default task-2) Resolved [org.springframework.web.HttpRequestMethodNotSupportedException: Request method 'POST' not supported] 

当我访问以下网址时 http://localhost:8080/ProjectFE/uregistration并且网站显示

when I go to the following URL http://localhost:8080/ProjectFE/uregistration and the website shows

不允许使用 HTTP 405 方法

HTTP 405 Method not allowed

这是我的控制器代码:

package controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import model.daoimpl.UserinfoDaoImpl;
import model.dao.IUserinfoDAO;
import model.entity.Userinfo;

@Controller
public class RegistrationController {
    @RequestMapping(value="/registration",method = RequestMethod.GET)
    public String addRegistrationPage() {
        return "registrationpage";
    }
    @RequestMapping(value="/uregistration",method = RequestMethod.POST)
    public String addURegistrationPage(@ModelAttribute("User")Userinfo u) {
        IUserinfoDAO iu = new UserinfoDaoImpl();
        boolean b = iu.insertInfo(u);
        if(b)
            return "success";
        else
            return "registrationpage";
    }

}

那我该怎么办?另外，如果需要任何其他代码，请评论我将编辑帖子，谢谢.

So what should I do ? Also if any other code is required please comment I'll edit the post, Thankyou.

推荐答案

对于那些我们有相关问题的人，当我使用带有空格的 @PathVariable 而不是 @RequestBody 发帖时遇到了这个问题

For those we have a related issue, I had this problem when I post using a @PathVariable with space in it rather than @RequestBody
