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

the class RowBoundsTest method testWithRowboundsAndCountTrue.

/**
     * 使用Mapper接口调用时，使用PageHelper.startPage效果更好，不需要添加Mapper接口参数

    CountryMapper countryMapper = sqlSession.getMapper(CountryMapper.class);
    try {
        //limit=0,这时候相当于用分页插件求count,但是前提必须是配置rounbounds方式求count，否则都是-1
        //这里由于没有配置，应该都是-1
