### 一 创建一个springboot项目 ###

pom.xml文件如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
      <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
      </parent>
      <groupId>com.bjsxt</groupId>
      <artifactId>08-spring-boot-view-jsp</artifactId>
      <version>0.0.1-SNAPSHOT</version>
      
      
      <properties>
      	<java.version>1.7</java.version>
      </properties>
      
      <dependencies>
      
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    	    
    	<dependency>
    		<groupId>javax.servlet</groupId>
    		<artifactId>jstl</artifactId>
    	</dependency>
    	
    	<dependency>
    		<groupId>org.apache.tomcat.embed</groupId>
    		<artifactId>tomcat-embed-jasper</artifactId>
    		<scope>provided</scope>
    	</dependency>
    </dependencies>
    </project>

### 二 创建Controller ###

package com.bjsxt.controller;
    
    import java.util.ArrayList;
    import java.util.List;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.bjsxt.model.Users;
    
    /**
     * SpringBoot整合jsp
     *
     *
     */
    @Controller
    public class UserController {
    	/*
    	 * 处理请求，产生数据
    	 */
    	@RequestMapping("/showUser")
    	public String showUser(Model model){
    		List<Users> list = new ArrayList<>();
    		list.add(new Users(1,"张三",20));
    		list.add(new Users(2,"李四",22));
    		list.add(new Users(3,"王五",24));
    		
    		//需要一个Model对象
    		model.addAttribute("list", list);
    		//跳转视图
    		return "userList";
    	}
    }

### 三 创建application.properties ###

spring.mvc.view.prefix=/WEB-INF/jsp/
    spring.mvc.view.suffix=.jsp
    server.port=8070

对应的创建文件：

### 四 前端jsp ###

<%@ page language="java" contentType="text/html; charset=UTF-8"
        pageEncoding="UTF-8"%>
    <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    	<table border="1" align="center" width="50%">
    		<tr>
    			<th>ID</th>
    			<th>Name</th>
    			<th>Age</th>
    		</tr>
    		<c:forEach items="${list }" var="user">
    			<tr>
    				<td>${user.userid }</td>
    				<td>${user.username }</td>
    				<td>${user.userage }</td>	
    			</tr>
    		</c:forEach>
    	</table>
    </body>
    </html>

### 五 创建启动类启动 ###

package com.bjsxt;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * SpringBoot启动类
     *
     *
     */
    @SpringBootApplication
    public class App {
    
    	public static void main(String[] args) {
    		SpringApplication.run(App.class, args);
    	}
    }

启动测试：
