springboot用thymeleaf模板的paginate分頁(相似博客園分頁)

本文根據一個簡單的user表爲例，展現 springboot集成mybatis，再到前端分頁完整代碼；

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&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driverClassName=com.mysql.jdbc.Driver
# Advanced configuration...
spring.datasource.max-active=50
spring.datasource.max-idle=6

spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html 
spring.thymeleaf.cache=false

啓動類 Application.java

@SpringBootApplication
@MapperScan("com.boot.mapper")
public class Application { 
     //定義一個全局的記錄器，經過LoggerFactory獲取
    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);  
    }  
}  

以一個簡單的user對象爲例

 private Integer id;

    private String name;

    private String password;

controller層

@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));
　　　　　mv.setViewName("userlist");
        return mv;
    }
}

service層

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>

到此時後臺代碼結束

附加個page工具類

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;
}

前端代碼開始

statis目錄下加入以下幾個文件

 

在templates目錄下創建一個前端分頁工具頁面 page.html,（雖然代碼很少，封裝這點東西花費我半天時間！！）

 

<!DOCTYPE html >
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:th="http://www.thymeleaf.org">
<div th:fragment="page">
    <div id="page"></div>
<link rel="stylesheet" th:href="@{/css/style.css}"  />
<script type="text/javascript" th:src="@{/js/page.js}"></script>
<script th:inline="javascript">/*<![CDATA[*/
    var size=[[${page.pagecount}]];
    if(size>1)
     Pagination.Init(document.getElementById('page'), {
            size: size, // pages size
            page: [[${page.pageon}]],  // selected page
            step: 3   // pages before and after current
        });
     /*]]>*/
function back(page_index){
    /*<![CDATA[*/
    if([[${page.pageon}]]==page_index) 
        return;
    var url=document.getElementById('page').parentNode.getAttribute('url');var tourl;
    if(url.indexOf('?')>0)
        tourl=url+'&pageon='+page_index;
    else
        tourl=url+'?pageon='+page_index;
        window.location.href=tourl;
    /*]]>*/
}
</script>
</div>
</html>

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>用戶列表</title>

</head>
<body>
<div style="width: 1000px;" >
    <table style="border-width: 1px;border-style: dashed;">
        <tr>
            <td>ID</td>
            <td>姓名</td>
            <td>密碼</td>
        </tr>
        <tr th:each="user:${list}">
            <td th:text="${user.id}">ID</td>
            <td th:text="${user.name}">姓名</td>
            <td th:text="${user.password}">密碼</td>
        </tr>
    </table>
    <div th:include="page :: page"  url="/userlist"></div>
</div>
    
</body>
</html>

 

能夠看到 引用分頁的代碼 只有一句，是否是很好用

<div th:include="page :: page"  url="/userlist"></div>

分頁效果圖
