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;
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

spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-
spring.thymeleaf.content-type=text/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="")int pageon
,ModelAndView mv){
mv.addAllObjects(uSer.UserList(pageon));
mv.setViewName("userlist");
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() 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 = ;
this.pageon = pageon;
this.row = row;
this.rowcount = rowcount;
compute();
} public Page(int pageon, int row) {
pageNumber = ;
this.pageon = pageon;
this.row = row;
}
public Page(int pageon) {
pageNumber = ;
this.pageon = pageon;
} public Page() {
pageNumber = ;
} public int getPageNumber() {
return pageNumber;
} public void setPageNumber(int pageNumber) {
this.pageNumber = pageNumber;
} public void compute() {
if (rowcount <= )
return;
if (row <= )
row = ;
pagecount = rowcount % row != ? rowcount / row + : rowcount / row;
if (pageon > pagecount)
pageon = pagecount;
if (pageon < )
pageon = ;
start = (pageon - ) * 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">
<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=[[${page.pagecount}]];
if(size>)
Pagination.Init(document.getElementById('page'), {
size: size, // pages size
page: [[${page.pageon}]], // selected page
step: // pages before and after current
});
/*]]>*/
function back(page_index){
/*<![CDATA[*/
if([[${page.pageon}]]==page_index)
return;
var url=document.getElementById('page').parentNode.getAttribute('url');var tourl;
if(url.indexOf('?')>)
tourl=url+'&pageon='+page_index;
else
tourl=url+'?pageon='+page_index;
window.location.href=tourl;
/*]]>*/
}
</script>
</div>
</html>
创建userlist.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8"/>
<title>用户列表</title> </head>
<body>
<div style="width: 1000px;" >
<table style="border-width: 1px;border-style: dashed;">
<tr>
<td>ID</td>
<td>姓名</td>
<td>密码</td>
</tr>
<tr th:each="user:${list}">
<td th:text="${user.id}">ID</td>
<td th:text="${user.name}">姓名</td>
<td th:text="${user.password}">密码</td>
</tr>
</table>
<div th:include="page :: page" url="/userlist"></div>
</div> </body>
</html>
可以看到 引用分页的代码 只有一句,是不是很好用
<div th:include="page :: page" url="/userlist"></div>
分页效果图
谢谢观看
下载插件连接 (有两个插件 一个是滚动显示,一个类似 博客园分页)
