代码实现：MyBatis查询，返回值Map或List

一、返回值Map

1、mapper.xml

	<select id="selectUserMapLimitOne" resultType="java.util.HashMap">
		select id,name
		from
		user order by id desc limit 1
	</select>

2、接口定义

	/**
	 * 获取仅含一个的map（map的size=字段个数）
	 * @return
	 */
	Map<String,Object> selectUserMapLimitOne();

二、返回值List<Map>

1、mapper.xml

	<select id="selectUserMapList" resultType="java.util.HashMap">
		select id,name from
		user order by id desc limit 2
	</select>

2、接口定义

	/**
	 * 获取map list
	 * @return
	 */
	List<Map<String,Object>> selectUserMapList();
