Mybatis框架模糊查询+多条件查询

一、ISmbmsUserDao层

 //根据姓名模糊查询
    public List<Smbms> getUser(); //多条件查询
    public List<Smbms> getLikeUser(@Param("userName") String userName , @Param("userCode") String userCode );

二、小配置文件 ISmbmsUserDao.xml

<!--根据姓名模糊查询-->
    <select id="getUser" resultType="com.smbms.entity.Smbms">
        <!--select * from smbms_user where userName like CONCAT('%',#{userName},'%')--> select * from smbms_user where userName like '%' #{userName} '%'
    </select>

<!--多条件查询-->
    <select id="getLikeUser" resultType="com.smbms.entity.Smbms">
        <!--select * from smbms_user where userName like CONCAT('%',#{userName},'%')--> select * from smbms_user where userName like '%' #{userName} '%' and userCode like '%' #{userCode} '%'
    </select>

三、测试类

//根据姓名模糊查询
        /*List<Smbms> getUser=sqlSession.selectList("getUser","马"); for (Smbms users:getUser) { System.out.println(users.getUserName()); }*/

        //多条件查询
        ISmbmsUserDao mapper=sqlSession.getMapper(ISmbmsUserDao.class); List<Smbms> getUser=mapper.getLikeUser("马","yuan"); for (Smbms users:getUser) { System.out.println(users.getUserName()+"================="+users.getUserpwd()); }
