mybatis-paginator分页工具的使用简述

1、引入依赖包

com.github.miemiedev mybatis-paginator 1.2.17

2、Mybatis配置文件添加分页插件

3、applicationContext.xml文件中增加属性配置

4、创建一个查询，mybatis映射文件

SELECT p.id FROM test1 b join test2 p on b.usr_no = p.usr_no where p.transfer_sts = '2' and b.tm_smp >= #{tmSmpStart} and b.tm_smp <= #{tmSmpEnd} and b.CUR_AC_BAL > 0

5、创建一个接口

package com.test.repository; import com.github.miemiedev.mybatis.paginator.domain.PageBounds; import org.apache.ibatis.annotations.Param; import java.util.List; public interface TestRepository { List selectdUserListPage(@Param("tmSmpStart") String tmSmpStart, @Param("tmSmpEnd") String tmSmpEnd,@Param("pageBounds") PageBounds pageBounds); }

6、具体的调用和使用

package com.test; import com.github.miemiedev.mybatis.paginator.domain.PageBounds; import com.github.miemiedev.mybatis.paginator.domain.PageList; import com.test.repository; import org.joda.time.DateTime; import org.junit.Test; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.junit.BeforeClass; import org.junit.FixMethodOrder; import org.junit.Test; import org.junit.runner.RunWith; import org.junit.runners.MethodSorters; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.TestExecutionListeners; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import org.springframework.test.context.support.DependencyInjectionTestExecutionListener; import org.springframework.test.context.transaction.TransactionalTestExecutionListener;import java.util.ArrayList; import java.util.List; @RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {"classpath:META-INF/service-conf/service.xml"})@TestExecutionListeners(value = {DependencyInjectionTestExecutionListener.class, TransactionalTestExecutionListener.class})@FixMethodOrder(MethodSorters.NAME_ASCENDING) public class BalTransferServiceTest{ private static Logger log = LoggerFactory.getLogger(BalTransferServiceTest.class); @Autowired private TestRepository testRepository; @Test public void testSelectPage() { List userIdList = new ArrayList<>(); String tmSmpStart = DateTime.now().minusDays(Integer.valueOf(30)).toString("yyyyMMddHHmmss"); String tmSmpEnd = DateTime.now().toString("yyyyMMddHHmmss"); int page = 1; int pageSize = 20; PageBounds pageBounds = new PageBounds(page, pageSize, Boolean.TRUE); List tempList = testRepository.selectdVipUserListPage(tmSmpStart, tmSmpEnd, pageBounds); PageList pageList = (PageList) tempList; userIdList.addAll(tempList); log.info("tempList={},Page={},totalCount={},TotalPages={}", tempList.size(), pageList.getPaginator().getPage(), pageList.getPaginator().getTotalCount(), pageList.getPaginator().getTotalPages()); Integer totalPages = pageList.getPaginator().getTotalPages(); //如果还有大于1页的数据，需要继续翻页进行查询，这个时候可以控制不查询totalcount的查询 for (int i = 2; i <= totalPages; i++) { pageBounds = new PageBounds(i, pageSize, Boolean.FALSE); tempList = testRepository.selectdUserListPage(tmSmpStart, tmSmpEnd, pageBounds); userIdList.addAll(tempList); } log.info("userIdList={}", userIdList.size()); for (String temp : userIdList) { log.info("id={}", temp); } } }

7、使用PageBounds这个对象来控制结果的输出，常用的使用方式一般都可以通过构造函数来配置。

//默认构造函数不提供分页，返回ArrayList new PageBounds();   //取TOPN操作，返回ArrayList new PageBounds(int limit);   //只排序不分页，返回ArrayList new PageBounds(Order... order);   //默认分页，返回PageList new PageBounds(int page, int limit);   //分页加排序，返回PageList new PageBounds(int page, int limit, Order... order);   //使用containsTotalCount来决定查不查询totalCount,即返回ArrayList还是PageList new PageBounds(int page, int limit, List orders, boolean containsTotalCount);
