Foreword

This article is for SpringBoot2.0.2 version, integrate mybatis, pagination plug-ins, druid and other components, to achieve a complete web service, providing restful style interface.

SpringBoot integrated MyBatis has two ways, one simple way is to use MyBatis official offer:
a, mybatis-spring-boot-starter ( article explain)
Second, I recommend another way is the way of integration:
        that is still used a similar configuration mybatis-spring, this approach need to write some code, but you can easily control the configuration of MyBatis, and add components. Reference: https://my.oschina.net/bianxin/blog/1602958

Basic framework

①: In http://start.spring.io/, configure your project information and download I was "2.0.2.RELEASE", I figure below:

Add the integration of related packages:

<!-- 2.0后包含spring-boot-starter的web服务包 -->
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
	<groupId>mysql</groupId>
	<artifactId>mysql-connector-java</artifactId>
	<scope>runtime</scope>
</dependency>
<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter</artifactId>
	<version>1.3.2</version>
</dependency>
<dependency>
	<groupId>com.alibaba</groupId>
	<artifactId>druid-spring-boot-starter</artifactId>
	<version>1.1.10</version>
</dependency>
<dependency>
	<groupId>com.github.pagehelper</groupId>
	<artifactId>pagehelper-spring-boot-starter</artifactId>
	<version>1.2.5</version>
</dependency>

The only attribute configuration file

Application.properties project does not use file and use a more concise application.yml file (directly change the suffix): 

server:
  port: 8080
spring:
    application:
        name: user-center
    datasource:
        name: test
        url: jdbc:mysql://127.0.0.1:3306/xin
        username: root
        password: root
        # 使用druid数据源
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.jdbc.Driver
        filters: stat
        maxActive: 20
        initialSize: 1
        maxWait: 60000
        minIdle: 1
        timeBetweenEvictionRunsMillis: 60000
        minEvictableIdleTimeMillis: 300000
        validationQuery: select 'x'
        testWhileIdle: true
        testOnBorrow: false
        testOnReturn: false
        poolPreparedStatements: true
        maxOpenPreparedStatements: 20
mybatis:
  mapper-locations: classpath:mapping/*.xml
  type-aliases-package: com.winter.model
#pagehelper分页插件
pagehelper:
  helperDialect: mysql
  reasonable: true
  supportMethodsArguments: true
  params: count=countSql
#日志级别
logging:
  level:
    com.xin.usercenter.dao: debug

Something else and the same as before, so the integration is over.

Paging implementation code:

public PageInfo<User> getUserBySearch(AppPage<User> page) {
	// TODO Auto-generated method stub
	PageHelper.startPage(page.getPageNum(),page.getPageSize());
	List<User> list=userDao.queryUserList(page.getParam());
	PageInfo<User> pageInfo = new PageInfo<User>(list);
	return pageInfo;
}

PageInfo returned data structure is as follows:

{
  "total": 5,
  "list": [
    {
      "id": 1,
      "loginName": "admin",
      "password": "123123",
      "nickname": "ADMIN",
      "type": 1,
      "state": 1,
      "note": "超级管理员",
      "createTime": "2018-04-28 15:15:46",
      "updateTime": "2018-04-28 15:16:37",
      "updateUid": 1,
      "loginIp": null,
      "loginAddr": null
    },
    {
      "id": 2,
      "loginName": "bian",
      "password": "123456",
      "nickname": "Bian",
      "type": 1,
      "state": 1,
      "note": "普通用户",
      "createTime": "2018-06-21 11:25:31",
      "updateTime": "2018-06-21 11:40:52",
      "updateUid": 0,
      "loginIp": null,
      "loginAddr": null
    }
  ],
  "pageNum": 1,
  "pageSize": 2,
  "size": 2,
  "startRow": 1,
  "endRow": 2,
  "pages": 3,
  "prePage": 0,
  "nextPage": 2,
  "isFirstPage": true,
  "isLastPage": false,
  "hasPreviousPage": false,
  "hasNextPage": true,
  "navigatePages": 8,
  "navigatepageNums": [
    1,
    2,
    3
  ],
  "navigateFirstPage": 1,
  "navigateLastPage": 3,
  "firstPage": 1,
  "lastPage": 3
}

Personal feeling is the official return of this data structure is perfect, so the direct use of the PageInfo.
