springboot内部对jsp的支持并不是特别理想，而springboot推荐的视图是Thymeleaf，对于java开发人员来说还是大多数人员喜欢使用jsp

1、创建maven项目，添加pom依赖

<!--springboot项目依赖的父项目-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.0.RELEASE</version>
    </parent>

    <dependencies>
        <!--注入springboot启动器-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- jstl标签库 -->
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
        </dependency>
        <!-- jasper，tomcat对jsp的监听 -->
        <dependency>
            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>
    </dependencies>

2、创建springboot的全局配置文件application.porerties

#视图层位置前缀
spring.mvc.view.prefix=/WEB-INF/jsp/
#视图层后缀
spring.mvc.view.suffix=.jsp

3、创建controller

package com.bjsxt.controller;

import com.bjsxt.pojo.User;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by Administrator on 2019/2/6.
 */
@Controller
public class UserController {

    @RequestMapping("/toUserList")
    public String toUserList(Model model){
        List<User> userList=new ArrayList<User>();
        userList.add(new User(1L,"张三","男"));
        userList.add(new User(2L,"李四","女"));
        userList.add(new User(3L,"王五","男"));
        model.addAttribute("userList",userList);
        return "user_list";
    }
}

4、创建jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <title>用户列表</title>
</head>
<body>

    <table border="1px solid red">
        <tr>
            <th>id</th>
            <th>姓名</th>
            <th>性别</th>
        </tr>
        <c:forEach items="${userList}" var="user">
            <tr>
                <td>${user.id}</td>
                <td>${user.name}</td>
                <td>${user.sex}</td>
            </tr>
        </c:forEach>
    </table>
</body>
</html>

5、创建启动类

package com.bjsxt;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Created by Administrator on 2019/2/6.
 */
@SpringBootApplication
public class App {

    public static void main(String[] args){
        SpringApplication.run(App.class,args);
    }
}
