1、pom.xml

        </plugins>
    </build>

</project>

2、配置文件

（1）application.yml (切换环境)

spring:
  profiles:
    active: dev

（2）application-dev.yml（开发环境）

#开发环境
server:
  port: 8081

spring:
  datasource:
    username: root
    password:
    url: jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
    driver-class-name: com.mysql.jdbc.Driver

mybatis:
  type-aliases-package: com.example.demo.entity
  mapper-locations: classpath:mapper/*.xml

  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update

  thymeleaf:
    cache: false #开发时关闭缓存,不然没法看到实时页面
    prefix: classpath:/templates/
    check-template-location: true  #check-tempate-location: 检查模板路径是否存在
    suffix: .html
    encoding: UTF-8
    mode: HTML5
    servlet:
      content-type: text/html

（3）application-prod.yml（生产环境）

#生产环境
server:
  port: 80

spring:
  datasource:
    username: root
    password:
    url: jdbc:mysql://localhost:3306/springboot?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
    driver-class-name: com.mysql.jdbc.Driver
mybatis:
  type-aliases-package: com.example.demo.entity
  mapper-locations: classpath:mapper/*.xml

  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update

  thymeleaf:
    cache: false #开发时关闭缓存,不然没法看到实时页面
    prefix: classpath:/templates/
    check-template-location: true  #check-tempate-location: 检查模板路径是否存在
    suffix: .html
    encoding: UTF-8
    mode: HTML5
    servlet:
      content-type: text/html

3、后台功能代码

（1）实体类

package com.example.entity;

import java.io.Serializable;

public class TUser implements Serializable {

	private Integer id;
	private String name;
	private Integer age;

	public Integer getId() {
		return id;
	}

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

	public String getName() {
		return name;
	}

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

	public Integer getAge() {
		return age;
	}

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

（2）dao层

package com.example.mapper;

import com.example.entity.TUser;
import org.apache.ibatis.annotations.*;
import org.apache.ibatis.type.JdbcType;

import java.util.List;

public interface TUserMapper {

	@Select("select * from user")
	@Results({
			@Result(property = "username", column = "username", jdbcType = JdbcType.VARCHAR),
			@Result(property = "password", column = "password")
	})
	List<TUser> findAll();
}

（3）业务层（service）

package com.example.service.impl;

import com.example.entity.TUser;
import com.example.mapper.TUserMapper;
import com.example.service.TUserService;
import org.springframework.stereotype.Service;

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

@Service
public class TUserServiceImpl implements TUserService {

	@Resource
	private TUserMapper tUserMapper;

	@Override
	public List<TUser> findAll() {
		return tUserMapper.findAll();
	}
}

package com.example.service;

import com.example.entity.TUser;

import java.util.List;

public interface TUserService {

	List<TUser> findAll();
}

Controller层：

package com.example.demo.controller;

import com.example.demo.entity.TUser;
import com.example.demo.service.TUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
public class TUserController {

	@Autowired
	TUserService tUserService;

	@RequestMapping("/")
	public String listUI(){
		return "redirect:/list";
	}

	@RequestMapping("/list")
	public String hello(Model model){
		List<TUser> all = tUserService.findAll();
		model.addAttribute("all",all);
		return "index";
	}
}

2、前端页面

页面一般存在在 templates 目录下

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>yyshop</title>
    <link rel="stylesheet" th:href="@{/css/bootstrap.css}">
    <link rel="stylesheet" th:src="@{/js/jquery-3.1.1.min.js}">
</head>
<body class="container">
<!--<img th:src="@{/img/bg.jpg}">-->
    <br>
    <h1>Information  <small>Student List</small></h1>
    <br>
    <div class="alert alert-danger  alert-dismissible" role="alert">
        <span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span>
        <span class="sr-only">Error:</span>
        Paging function to be developed...
    </div>
    <br>
    <div class="panel panel-default">
        <div class="panel-heading">Student</div>
        <table class="table table-striped">
            <THEAD>
                <tr>
                    <th>ID</th>
                    <th>Name</th>
                    <th>Password</th>
                    <th>Phone</th>
                    <th>Edit</th>
                    <th>Delete</th>
                </tr>
            </THEAD>
            <TBODY>
                <tr th:each = "user:${all}">
                    <td th:text="${user.id}" ></td>
                    <td th:text="${user.name}" ></td>
                   <!-- <td th:text="${user.password}" ></td>
                    <td th:text="${user.phone}" ></td>
                    <td ><a th:href="${'/edit/'+user.userId}">edit</a></td>
                    <td><a th:href="${'/del/'+user.userId}" >delete</a></td>-->
                </tr>
            </TBODY>
        </table>
    </div>
    <a class="btn btn-info" href="/toAdd" role="button">Add</a>
    &nbsp;&nbsp;&nbsp;
    <a class="btn btn-info" href="/seach" role="button">Seach</a>

</body>
</html>
