Mybatis图文并茂讲解分页插件

<!-- 注意：分页助手的插件  配置在通用mapper之前 -->
<plugin interceptor="com.GitHub.pagehelper.PageHelper">
    <!-- 指定方言 -->
    <property name="dialect" value="Mysql"/>
</plugin>

@Test
public void testPageHelper(){
    //设置分页参数
    PageHelper.startPage(1,2);
    List<User> select = userMapper2.select(null);
    for(User user : select){
        System.out.println(user);
    }
}

//其他分页的数据
PageInfo<User> pageInfo = new PageInfo<User>(select);
System.out.println("总条数："+pageInfo.getTotal());
System.out.println("总页数："+pageInfo.getPages());
System.out.println("当前页："+pageInfo.getPageNum());
System.out.println("每页显示长度："+pageInfo.getPageSize());
System.out.println("是否第一页："+pageInfo.isIsFirstPage());
System.out.println("是否最后一页："+pageInfo.isIsLastPage());
