4.com.springtest.controllers.HelloWorldController.java
package com.springtest.controllers;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import static org.springframework.web.bind.annotation.RequestMethod.*;
@Controller
@RequestMapping("/hello")
public class HelloWorldController {
@RequestMapping(value="/show",method=GET)
public String helloWorld(@RequestParam("param1") String param1,Model model) {
model.addAttribute("param1", param1);
return "helloWorld";
}
}
1.js静态文件放在webapp/resources文件夹下
2.webapp/WEB-INF/views/helloWorld.jsp内容
<%@ 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>
<link rel="stylesheet" type="text/css" href="../resources/bootstrap/css/bootstrap.min.css"/>

</head>
<body>
param1:
<c:out value="${param1}"/>
</body>
</html>
另外，如果期望访问项目根目录，即能够看到页面（类似欢迎页面效果）。则controller可以这样写：
@Controller
@RequestMapping(value={" ","/"})
public class HomeController {
@RequestMapping(value={"index","index.html","/"})
public String index(Model model) {
return "index";
}
}
