Mabatis_配置中出现的error

1. 不区分大小写

<mapper namespace="Message">

<resultMap type="com.imooc.bean.Message" id="MessageResult">
    <id column="id" jdbcType="INTEGER" property="id"/>
    <result column="COMMAND" jdbcType="VARCHAR" property="command"/>
    <result column="DESCRIPTION" jdbcType="VARCHAR" property="description"/>
    <result column="CONTENT" jdbcType="VARCHAR" property="content"/>
  </resultMap>

<select id="queryMessageList" parameterType="com.imooc.bean.Message" resultMap="MessageResult">
    select ID,COMMAND,DESCRIPTION,CONTENT from MESSAGE
  </select>
</mapper>

2. jdbcType打错了

<mapper namespace="Message">

<resultMap type="com.imooc.bean.Message" id="MessageResult">
    <id column="id" jdbcType="INTEGER" property="id"/>
    <result column="COMMAND" jdbcType="VARCHAR" property="command"/>

    <result column="CONTENT" jdbcType="VARCHER" property="content"/>
  </resultMap>

<select id="queryMessageList" parameterType="com.imooc.bean.Message" resultMap="MessageResult">
    select ID,COMMAND,DESCRIPTION,CONTENT from MESSAGE
  </select>
</mapper>

3.mapper的SQL ID写错了

public static  List<Message> query() {
        DBAccess dbaccess = new DBAccess();
        List<Message> messageList = new ArrayList<Message>();
        SqlSession session =null;
        try {
            Message m =new Message();
            session = dbaccess.getSqlSession();
            messageList = session.selectList("Message.queryMessageList",m);
        } catch (IOException e) {
            // TODO Auto-generated catch block
