SpringBoot+SpringMvc+Mysql+Mybatis整合访问不到jsp页面

[待解决问题]

开发工具：IDEA

项目结构：

第一步：pom文件

            </plugin>
        </plugins>
    </build>


</project>

第二步：application.properties文件

server.port=8080
server.context-path=/zm/
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=root
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
#指定mybatis基础配置文件和实体类映射文件的地址
#mybatis.config-location=classpath:mybatis/mybatis-config.xml
#mybatis.mapper-locations=classpath:mybatis/mapper/*.xml
#设置页面跳转
spring.mvc.view.prefix=/jsp/
spring.mvc.view.suffix=.jsp

第三步：SpringmvcAplication.java

package com.zm.springmvc;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.zm.springmvc.dao")
public class SpringmvcApplication {

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

第四步：UserController.java

package com.zm.springmvc.controller;

import com.zm.springmvc.bean.User;
import com.zm.springmvc.service.UserService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.annotation.Resource;
import java.util.List;

@Controller
public class UserController {
        @Resource
        private UserService userService;

    @GetMapping("/")
    @ResponseBody
    public String index() {
        return "Hello  world!";
    }

    @GetMapping("/index")
    public String one() {
        return "welcome";
    }

        @RequestMapping("/mvc")
        public String welcome(Model model) {
            List<User> users = userService.getList();
            model.addAttribute("users", users);
            System.out.println("user"+users);
            return "welcome";
        }
}

第五步：Userservice.java

package com.zm.springmvc.service;

import com.zm.springmvc.bean.User;
import com.zm.springmvc.dao.UserMapper;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

@Service
public class UserService {
    @Resource
    private UserMapper userMapper;

    public List<User> getList() {
        return userMapper.selectUser();
    }
}

第六步：UserMapper.java

package com.zm.springmvc.dao;

import com.zm.springmvc.bean.User;
import org.apache.ibatis.annotations.Select;

import java.util.List;

public interface UserMapper {
    @Select("select * from user")
    List<User> selectUser();
}

第七步：User.java

package com.zm.springmvc.bean;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
@Entity
public class User {
    @Id
    @GeneratedValue
    private int id;
    private String name;
    private int age;

    public User() {
    }

    public User(int id, String name, int age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

第八步：welcom.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<head>
    <title>jsp</title>
</head>
<body>
<h3>welcome to jsp page....</h3>
<table border="1px">
    <tr>
        <td>序号</td>
        <td>姓名</td>
        <td>年齡</td>
    </tr>
    <c:forEach items="${users}" var="user">
        <tr>
            <td>${user.id}</td>
            <td>${user.name}</td>
            <td>${user.age}</td>
        </tr>
    </c:forEach>
</table>
</body>
</html>

然后启动，没有报错，访问页面时候访问不到
