Question

我一直在从this website构建一个Spring webapp。当我运行教程代码时，应用程序运行完美。但是，当我运行我的改编版代码时，我收到以下错误：

我不知道为什么会这样;我已经有效地复制并粘贴了整个代码库，只是将数据更改为Campaign而不是Strategy。

这是我的配置类：

package com.bridge.campaignspring.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import com.bridge.campaignspring.model.Campaign;
import com.bridge.campaignspring.service.CampaignService;

@Controller
@RequestMapping(value="/campaign")
public class CampaignController {

    @Autowired
    private CampaignService campaignService;

    @RequestMapping(value="/add", method=RequestMethod.GET)
    public ModelAndView addCampaignPage() {
        ModelAndView modelAndView = new ModelAndView("campaign-add");
        modelAndView.addObject("campaign", new Campaign());
        return modelAndView;
    }

    @RequestMapping(value="/add", method=RequestMethod.POST)
    public ModelAndView addingCampaign(@ModelAttribute Campaign campaign) {
        ModelAndView modelAndView = new ModelAndView("home");
        campaignService.addCampaign(campaign);
        String message = "Campaign was added sucessfully";
        modelAndView.addObject("message", message);
        return modelAndView;
    }

    @RequestMapping(value="/list")
    public ModelAndView listOfCampaigns() {
        ModelAndView modelAndView = new ModelAndView("campaign-list");
        List<Campaign> campaigns = campaignService.getCampaigns();
        modelAndView.addObject("campaigns", campaigns);
        return modelAndView;
    }

    @RequestMapping(value="/edit/{id}", method=RequestMethod.GET)
    public ModelAndView editCampaignPage(@PathVariable Integer id) {
        ModelAndView modelAndView = new ModelAndView("campaign-edit");
        Campaign campaign = campaignService.getCampaign(id);
        modelAndView.addObject("campaign", campaign);
        return modelAndView;
    }

    @RequestMapping(value="/edit/{id}", method=RequestMethod.POST)
    public ModelAndView editingCampaign(@ModelAttribute Campaign campaign, @PathVariable Integer id) {
        ModelAndView modelAndView = new ModelAndView("home");
        campaignService.updateCampaign(campaign);
        String message = "Campaign edited successfully";
        modelAndView.addObject("message", message);
        return modelAndView;
    }

    @RequestMapping(value="/delete/{id}", method=RequestMethod.GET)
    public ModelAndView deleteCampaign(@PathVariable Integer id) {
        ModelAndView modelAndView = new ModelAndView("home");
        campaignService.deleteCampaign(id);
        String message = "Campaign deleted successfully";
        modelAndView.addObject("message", message);
        return modelAndView;        
    }
}

我无法访问我创建的任何已创建的.jsp。我只看到404错误。如果需要更多代码来解决此问题，请询问;我可以发布任何必要的东西。

编辑：这是我的CampaignController类：

onbeforeunload

Answer 1

您的网址应包含class Program { static void Main(string[] args) { Test a = Test.A; } } enum Test { A = 1, B = 1, }，...

网址由/campaign/add

中的注记属性定义

@RequestMapping

Answer 2

不完全确定发生了什么，但它可能是我的Tomcat配置中的内容。我删除了服务器然后重新添加它并且它有效。

Tomcat在Spring中出现404错误？
