Mybatis中如何传入map参数呢?

实现思路:
    1.将参数类型设置为map
	2.在xml中直接使用map的键值获取参数即可

xml
  <insert id="addUser" parameterType="map">
        insert into user (id,name,pwd) values (#{userid},#{username},#{userpwd});
    </insert>

Mapper接口
      //Map的使用
    int addUser(Map<String,Object> map);

//测试代码
//Map测试
    @Test
    public void addUser2() {
        SqlSession sqlSession = MyBatisUtil.getSqlSession();
        UserMapper mapper = sqlSession.getMapper(UserMapper.class);
        HashMap<String, Object> map = new HashMap<>();
        map.put("userid",8888);
        map.put("username","java爱好者");
        map.put("userpwd","java265.com");
        int result = mapper.addUser(map);
        if (result > 0) {
            System.out.println("添加成功!");
        }
        //增删改一定要提交事务！
        sqlSession.commit();
        sqlSession.close();
    }
