ViewResolver不会自动创建Spring MVC .jsp

时间：2016-07-18 11:31:24

标签： java jsp spring-mvc servlets

我是Spring MVC的新手。当我运行项目welcome.jsp打开时。然后我填写表格并按登录。直到现在它应该是全部，但是如果userID是didem并且passqord是123321，那么我想要success.jsp打开然后welcome.jsp应该重新打开..但实际得到的是404未找到 因为在网络浏览器中，网址链接如下所示：http://localhost:8080/CrunchifySpringMVCTutorial/welcome Idk为什么viewResolver没有把.jsp放在最后..任何帮助将不胜感激..

CrunchifyHelloWorld.java文件：

     package com.crunchify.controller;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.servlet.ModelAndView;

@Controller
public class CrunchifyHelloWorld {


    @RequestMapping(value = "/welcome", method = RequestMethod.GET)
    public String showLoginForm() {

        return "welcome";
    }

    @RequestMapping(value = "/welcome", method = RequestMethod.POST)
    public String verifyLogin(@RequestParam String userID,  @RequestParam String password){

        ModelAndView model = new ModelAndView();
        model.addObject("loginError", "Invalid Id AND/OR password");
        if(userID == "didem" && password == "123321")
        {
            return "success";
        }
        return "redirect:/";



    }
}

在web.xml中标记下面的chaneg并尝试一次。

<servlet>
        <servlet-name>crunchify</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
    <init-param> 
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/crunchify-servlet.xml </param-value> 
    </init-param>   
        <load-on-startup>1</load-on-startup>
    </servlet>

答案 2 :(得分：0)

返回“redirect：/ {welcome}”怎么样;如下所示。 

@RequestMapping(value = "/welcome", method = RequestMethod.POST)
    public String verifyLogin(@RequestParam String userID,  @RequestParam String password){

        ModelAndView model = new ModelAndView();
        model.addObject("loginError", "Invalid Id AND/OR password");
        if(userID == "didem" && password == "123321")
        {
            return "success";
        }
        return "redirect:/{welcome}";



    }
}
