mybatis pagehelper实现分页

jar包的版本一定要对应,不然会出现一系列的问题

下载jar包

<properties>
<!-- spring版本号 -->
<spring.version>4.0.2.RELEASE</spring.version>
<!-- mybatis版本号 -->
<mybatis.version>3.3.0</mybatis.version>
<!-- log4j日志文件管理包版本 -->
<slf4j.version>1.7.7</slf4j.version>
<log4j.version>1.2.17</log4j.version>
</properties>

配置分页过滤器

SqlMapConfig.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<!-- 配置管理器 -->
<configuration>

<plugins>
<plugin interceptor="com.github.pagehelper.PageHelper">
<!-- 4.0.0以后版本可以不设置该参数 -->
<property name="dialect" value="mysql"/>
<!-- 该参数默认为false -->
<!-- 设置为true时，会将RowBounds第一个参数offset当成pageNum页码使用 -->
<!-- 和startPage中的pageNum效果一样-->
<property name="offsetAsPageNum" value="true"/>
<!-- 该参数默认为false -->
<!-- 设置为true时，使用RowBounds分页会进行count查询 -->
<property name="rowBoundsWithCount" value="true"/>
<!-- 设置为true时，如果pageSize=0或者RowBounds.limit = 0就会查询出全部的结果 -->
<!-- （相当于没有执行分页查询，但是返回结果仍然是Page类型）-->
<property name="pageSizeZero" value="true"/>
<!-- 3.3.0版本可用 - 分页参数合理化，默认false禁用 -->
<!-- 启用合理化时，如果pageNum<1会查询第一页，如果pageNum>pages会查询最后一页 -->
<!-- 禁用合理化时，如果pageNum<1或pageNum>pages会返回空数据 -->
<property name="reasonable" value="true"/>
<!-- 3.5.0版本可用 - 为了支持startPage(Object params)方法 -->
<!-- 增加了一个`params`参数来配置参数映射，用于从Map或ServletRequest中取值 -->
<!-- 可以配置pageNum,pageSize,count,pageSizeZero,reasonable,orderBy,不配置映射的用默认值 -->
<!-- 不理解该含义的前提下，不要随便复制该配置 -->
<property name="params" value="pageNum=start;pageSize=limit;"/>
<!-- 支持通过Mapper接口参数来传递分页参数 -->
<property name="supportMethodsArguments" value="true"/>
<!-- always总是返回PageInfo类型,check检查返回类型是否为PageInfo,none返回Page -->
<property name="returnPageInfo" value="check"/>
</plugin>
</plugins>
</configuration>
=================================================================

将SqlMapConfig.xml分页过滤器配置在sqlSessionFactory模板中

<!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/cjt/mapping/*.xml"></property>
<property name="configLocation" value="classpath:SqlMapConfig.xml"></property>
</bean>

=================================================================

list列表查询此处省略(常用的查询list方式)

=================================================================

controller中的代码如下：

@SuppressWarnings("unchecked")
@RequestMapping(value="/queryProxy", method = {RequestMethod.POST,RequestMethod.GET })
public ModelAndView queryAllProxy(Model m,ProxyBusiness proxyBusiness,HttpServletRequest request,HttpServletResponse response){
String pageNum = request.getParameter("pageNum");
String pageSize =request.getParameter("pageSize");
int num = 1;
int size = 10;
if (pageNum != null && !"".equals(pageNum)) {
num = Integer.parseInt(pageNum);
}
if (pageSize != null && !"".equals(pageSize)) {
size = Integer.parseInt(pageSize);
}
PageHelper.startPage(num, size);
List<ProxyBusiness> ProxyBusinessList = proxyBusinessService.queryAllproxy(proxyBusiness);//list方法调用
PageInfo<ProxyBusiness> pagehelper = new PageInfo<ProxyBusiness>(ProxyBusinessList);
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("pagehelper", pagehelper);
modelAndView.setViewName("backend/proxyBusinessList");
return modelAndView;
}

使用modelAndView返回页面
