mybatis使用Hashmap传递参数

mapper

    <!--传递map的key -->
    <insert id="addUser2" parameterType="map">
        insert into mybatis.user (id , name ,password ) values(#{userid},#{username},#{password});
    </insert>

测试

    @Test
    public void addUser2(){
        SqlSession sqlSession = MybatisUtils.getSession();
        //sqlSession获取mapper
        UserMapper mapper= sqlSession.getMapper(UserMapper.class);
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("userid",5);
        map.put("username","hello");
        map.put("password","123456");
        mapper.addUser2(map);
        sqlSession.commit();
        sqlSession.close();
    }
