spring - 如何从控制器传递视图？

问题描述

我是 Spring MVC 的新手。我正在尝试使用多个视图。当我使用单个视图和单个控制器时，它可以完美运行。但是当我尝试从另一个视图打开一个视图时，我收到 HTTP 404 错误（未找到请求的资源）

项目目录结构

如图所示，我将 index.jsp 作为我的主页视图。从这个页面，我需要浏览另一个页面（viewpage1.jsp），它位于 WEB-INF/jsp 目录中。当我这样做时，我得到 HTTP 404 not found 错误。

HelloController.java

package com.springwebproject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloController
{
    @RequestMapping("/")
    public String home()
    {
        return "index";
    }
    @RequestMapping("/hello")
    public String display()
    {
       return "viewpage1";
    }
}

index.jsp

<h1>First View Page after Home page</h1>
</f:view>

</html>

标签： spring

解决方案

由于您已将映射指定为“/hello”以查看 viewpage1，因此您必须像这样更改您的 href：

<a href="/hello">Go to Next View</a>

让我知道，如果这有帮助。
