Example 38 with UserMapper

use of com.github.pagehelper.mapper.UserMapper in project Mybatis-PageHelper by pagehelper.

the class PageHelperTest method testMapperWithRowBounds.

/**
 * 使用Mapper接口调用时，对接口增加RowBounds参数，不需要修改对应的xml配置（或注解配置）
 * <p/>
 * RowBounds方式不进行count查询，可以通过修改Page代码实现
 * <p/>
 * 这种情况下如果同时使用startPage方法，以startPage为准
