本文根据一个简单的user表为例，展示 springboot集成mybatis，再到前端分页完整代码（新手自学，不足之处欢迎纠正）；

先看java部分

pom.xml 加入

application.properties文件

spring.datasource.platform=mysql
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root

spring.thymeleaf.suffix=.html

spring.thymeleaf.cache=false

启动类 Application.java

@SpringBootApplication
@MapperScan("com.boot.mapper")
public class Application { 
   //定义一个全局的记录器，通过LoggerFactory获取
  private final static Logger logger = LoggerFactory.getLogger(Application.class); 
   
  //----------------------------mybaits配置start-------------------------------------------
  //DataSource
  @Bean
  @ConfigurationProperties(prefix="spring.datasource")
  public DataSource dataSource() {
    return new org.apache.tomcat.jdbc.pool.DataSource();
  }
  //SqlSessionFactory
  @Bean
  public SqlSessionFactory sqlSessionFactoryBean() throws Exception {
 
    SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
    sqlSessionFactoryBean.setDataSource(dataSource());
 
    PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
 
    sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:mapper/*.xml"));
 
    return sqlSessionFactoryBean.getObject();
  }
  @Bean
  public PlatformTransactionManager transactionManager() {
    return new DataSourceTransactionManager(dataSource());
  }
  //------------------------------mybaits配置end---------------------------------
  public static void main(String[] args){ 
    System.out.println("Hello World!"); 
    SpringApplication.run(Application.class, args); 
  } 
}

以一个简单的user对象为例

private Integer id;
  private String name;
  private String password;

controller层

@RestController
public class UserController {
  @Autowired
  UserService uSer;
  @RequestMapping("userlist")
  public Object userlist(@RequestParam(value="pageon",defaultValue="1")int pageon
      ,ModelAndView mv){
    mv.addAllObjects(uSer.UserList(pageon));
    return mv;
  }
}

service层

public Map<String, Object> UserList(int pageon) {
    // TODO Auto-generated method stub
    Map<String,Object> map=new HashMap<String, Object>();
    Page page=new Page(pageon);
    page.setRowcountAndCompute(userMapper.selectPageListCount(null));
    map.put("page", page);
    map.put("list", userMapper.selectPageList(map));
    return map;
  }

UserMapper.xml

<select id="selectPageList" parameterType="java.util.Map" resultMap="BaseResultMap" >
  select id, name, password from user order by id limit #{page.start},#{page.row}
 </select>
 <select id="selectPageListCount" parameterType="java.util.Map" resultType="int" >
  select count(1) from user
 </select>

到此时后台代码结束

附加个page工具类

package com.boot.utils;
import java.io.Serializable;
public class Page implements Serializable {
  /**
   * 
   */
  private static final long serialVersionUID = 1L;
  public int getPageon() {
    return pageon;
  }
  public void setPageon(int pageon) {
    this.pageon = pageon;
  }
  public int getRowcount() {
    return rowcount;
  }
  public void setRowcount(int rowcount) {
    this.rowcount = rowcount;
  }
  public int getPagecount() {
    return pagecount;
  }
  public void setPagecount(int pagecount) {
    this.pagecount = pagecount;
  }
  public int getRow() {
    return row;
  }
  public void setRow(int row) {
    this.row = row;
  }
  public Page(int pageon, int row, int rowcount) {
    pageNumber = 11;
    this.pageon = pageon;
    this.row = row;
    this.rowcount = rowcount;
    compute();
  }
  public Page(int pageon, int row) {
    pageNumber = 11;
    this.pageon = pageon;
    this.row = row;
  }
  public Page(int pageon) {
    pageNumber = 11;
    this.pageon = pageon;
  }
  public Page() {
    pageNumber = 11;
  }
  public int getPageNumber() {
    return pageNumber;
  }
  public void setPageNumber(int pageNumber) {
    this.pageNumber = pageNumber;
  }
  public void compute() {
    if (rowcount <= 0)
      return;
    if (row <= 0)
      row = 10;
    pagecount = rowcount % row != 0 ? rowcount / row + 1 : rowcount / row;
    if (pageon > pagecount)
      pageon = pagecount;
    if (pageon < 1)
      pageon = 1;
    start = (pageon - 1) * row;
    end = pageon * row;
    if (end > rowcount)
      end = rowcount;
  }
  public int getStart() {
    return start;
  }
  public void setStart(int start) {
    this.start = start;
  }
  public int getEnd() {
    return end;
  }
  public void setEnd(int end) {
    this.end = end;
  }
  public void setRowcountAndCompute(int rowcount) {
    this.rowcount = rowcount;
    compute();
  }
  protected int pageon;
  protected int rowcount;
  protected int pagecount;
  protected int row;
  protected int start;
  protected int end;
  protected int pageNumber;
}

前端代码开始

statis目录下加入如下几个文件

在templates目录下建立一个前端分页工具页面 page.html,（虽然代码不多，封装这点东西花费我半天时间！！）

<!DOCTYPE html >
<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:th="http://www.thymeleaf.org">
<head th:fragment="page">
<link rel="stylesheet" th:href="@{/css/pagestyle.css}" rel="external nofollow" />
<script type="text/javascript" th:src="@{/js/jquery-3.1.1.min.js}"></script>
<script type="text/javascript" th:src="@{/js/jquery.paginate.js}"></script>
<script th:inline="javascript">
(function($) {
  /*<![CDATA[*/
  var count=[[${page.pagecount}]];
  var start=[[${page.pageon}]];
  /*]]>*/
  var url=$("#page").attr('url');
  var displaycnt=count>10?10:count;
  fenye(count,start,url,displaycnt);
})(jQuery);
  function fenye(count,start,url,displaycnt){
    /*<![CDATA[*/
    if(count<2) 
    return;
    /*]]>*/
    $("#page").paginate({
      count     : count,
      start     : start,
      display   : displaycnt,
      border          : true,
      border_color      : '#fff',
      text_color       : '#fff',
      background_color    : 'pink',  
      border_hover_color    : '#ccc',
      text_hover_color     : '#000',
      background_hover_color  : '#fff', 
      images          : true,
      mouse          : 'press',
      onChange: function(page_index) { 
        var tourl;
        /*<![CDATA[*/
        if(url.indexOf('?')>0)
          tourl=url+'&pageon='+page_index;
        else
          tourl=url+'?pageon='+page_index;
          window.location.href=tourl;
        /*]]>*/
      }
    });
  };
</script>
</head>
</html>

接下来就是引用分页插件了。

在templates目录下建立userlist.html.

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8"/>
<title>用户列表</title>
</head>
<body>
<div style="width: 1000px;" >
  <table style="border-width: 1px;border-style: dashed;">
    <tr>
      <td>ID</td>
      <td>姓名</td>
      <td>密码</td>
    </tr>
    <p th:each="user:${list}">
    <tr>
      <td th:text="${user.id}">ID</td>
      <td th:text="${user.name}">姓名</td>
      <td th:text="${user.password}">密码</td>
    </tr>
    </p>
  </table>
  <div id="page" url="/userlist" ></div>
  <div th:replace="page :: page"></div>
</div>
</body>
</html>

可以看到 引用分页的代码 只有两句，是不是很好用

<div id="page" url="/userlist" ></div>
<div th:replace="page :: page"></div>
