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>

2017-05-17 11:25:34,859 [main] DEBUG [Message.queryMessageList] - ==>  Preparing: select ID,COMMAND,DESCRIPTION,CONTENT from MESSAGE 
2017-05-17 11:25:34,892 [main] DEBUG [Message.queryMessageList] - ==> Parameters: 
2017-05-17 11:25:34,917 [main] DEBUG [Message.queryMessageList] - <==      Total: 5
Message [id=1, command=查看, description=精彩内容, content=精彩内容]
Message [id=2, command=段子, description=精彩段子, content=如果你的月薪是3000块钱，请记得分成五份，一份用来买书，一份给家人，一份给女朋友买化妆品和衣服，一份请朋友们吃饭，一份作为同事的各种婚丧嫁娶的份子钱。剩下的2999块钱藏起来，不要告诉任何人]
Message [id=3, command=新闻, description=今日头条, content=7月17日，马来西亚一架载有298人的777客机在乌克兰靠近俄罗斯边界坠毁。另据国际文传电讯社消息，坠毁机型为一架波音777客机，机载约280名乘客和15个机组人员。
乌克兰空管部门随后证实马航MH17航班坠毁。乌克兰内政部幕僚表示，这一航班在顿涅茨克地区上空被击落。马来西亚航空公司确认，该公司从阿姆斯特丹飞往吉隆坡的MH17航班失联，并称最后与该客机取得联系的地点在乌克兰上空。图为马航客机坠毁现场。]
Message [id=4, command=娱乐, description=娱乐新闻, content=昨日，邓超在微博分享了自己和孙俪的书法。夫妻同样写幸福，但差距很大。邓超自己都忍不住感慨字丑：左边媳妇写的。右边是我写的。看完我再也不幸福了。]
Message [id=6, command=彩票, description=中奖号码, content=查啥呀查，你不会中奖的！]

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="DESCRIPTION" jdbcType="VARCHAR" property="description"/>
    <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
           e.printStackTrace();
       } finally{
           if(session != null){
               session.close();
           }
       }
       if (messageList == null) System.out.println("message is null");
       return messageList;

   }

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