Mini框架使用演示

代码Gitee路径:Mini

这里已将源码中的com包放入了maven本地仓库的根路径下。

    @Select("select * from user where id = #{testId} and username = #{name}")
    User selectOne(@Param("testId") int id, @Param("name") String name);

        SqlSession sqlSession = build.openSession();
        UserMapper mapper = sqlSession.getMapper(UserMapper.class);
        User user = mapper.selectOne(41, "小刘");
        System.out.println("user = " + user);
    }
}

Mini架构参考Mybatis，代码自己diy，可以看作是个小型Mybatis。目前初步阶段，仍有许多限制不足。博主创作它也是想验证自己是否真的学会了Mybatis，因为我觉得学会一个东西，不仅局限于如何使用它，更应该扩展到如何制造它，整个过程就像是把电视机拆开之后，自己还能否重新拼凑出一个电视，这是一个有趣的过程。
