1.创建pojo类，实现对象的封装

package com.ws.domain;
    
    public class User {
    	private Integer userid;
    	private String username;
    	private Integer userage;
    	public Integer getUserid() {
    		return userid;
    	}
    	public void setUserid(Integer userid) {
    		this.userid = userid;
    	}
    	public String getUsername() {
    		return username;
    	}
    	public void setUsername(String username) {
    		this.username = username;
    	}
    	public Integer getUserage() {
    		return userage;
    	}
    	public void setUserage(Integer userage) {
    		this.userage = userage;
    	}
    	public User(Integer userid, String username, Integer userage) {
    		super();
    		this.userid = userid;
    		this.username = username;
    		this.userage = userage;
    	}
    	public User() {
    		super();
    		// TODO Auto-generated constructor stub
    	}
    	
    }

2.pom引入starter和freemarker坐标

<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.ws</groupId>
      <artifactId>springboot-freemarker</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>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>
      </dependencies>
    </project>

3.创建controller，将list放入到model中；

package com.ws.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.ws.domain.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";
    	}
    }

4.在resources目录下创建templates文件夹，创建userList.ftl文件，然后遍历循环

<html>
    	<head>
    		<title>展示用户数据</title>
    		<meta charset="utf-8"></meta>
    	</head>
    	
    	<body>
    		
    		<table border="1" align="center" width="50%">
    			
    			<tr>
    				
    				<th>ID</th>
    				<th>Name</th>
    				<th>Age</th>
    			</tr>
    			
    			<#list list as user >
    				<tr>
    					<td>${user.userid}</td>
    					<td>${user.username}</td>
    					<td>${user.userage}</td>
    				</tr>
    			</#list>	
    		</table>
    	</body>
    </html>

5.添加启动类，实现项目的启动

package com.ws;
    
    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);
    	}
    }
