Question

我正在尝试将hello.jsp页面作为输出，但它始终进入index.jsp页面。我尝试搜索其他各种东西但失败了，所以最后决定在这里发帖，所以你们中的任何一个都可以提供帮助。下面我附上了我的项目结构和所有文件......以及我在tomcat服务器上运行时看到的输出。

HelloController.java

package com.gami.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {

    @RequestMapping(value ="greeting")
    public String sayHello (Model model) {

        model.addAttribute("greeting", "Hello World");

        return "hello";
    }

hello.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1>${greeting}</h1>
</body>
</html>

的index.jsp

<html>
<body>
<h2>This is index - Hello World!</h2>
</body>
</html>

This is the output I get when I run the project on server

These are logs, server was started properly

Answer 1

healthTracker是您的根背景。

您可以在/greeting

访问您的控制器路径

@RequestMapping(value ="greeting")

因此，如果您想访问hello页面，您的网址应为：

http://localhost:1615/healthTracker/greeting

Answer 2

更新部署描述符（web.xml）中的servlet-mapping

<servlet-mapping>
        <servlet-name>healthTrackerServlet</servlet-name>
        <url-pattern>/*</url-pattern>

</servlet-mapping>

首先，检查您的服务器是否在1615上运行

如果是，那么

访问资源的基本URL具有以下形式

https://<IP>:<Listener-PORT>/<ROOT-CONTEXT-NAME>/<URL-SPECIFIED-FOR-RESOURCE>

所以请使用：http://localhost:1615/healthTracker/greeting

另外，建议您在@RequestMapping中指定请求方法，默认为GET

@RequestMapping(value ="greeting" , method = RequestMethod.POST)
    public String sayHello (Model model) {

        model.addAttribute("greeting", "Hello World");

        return "hello";
    }

如果您想将页面设为应用程序的默认页面。还有另一种方法可以在web.xml

中指定页面

<web-app>  
 ....  

  <welcome-file-list>  
   <welcome-file>hello.html</welcome-file>  
  </welcome-file-list>  
</web-app>

Answer 3

如果您希望hello.jsp作为默认值，则必须在index.jsp中保留一些代码段保持<jsp:forword page="greeting">

并在web.xml中更改为

<servlet-mapping>
        <servlet-name>healthTrackerServlet</servlet-name>
        <url-pattern>/*</url-pattern>

</servlet-mapping>
