myBatis外部的resultMap高级应用

  <resultMap id="BaseResultMap" type="com.lamsey.survey.entities.guest.User" >
    <id column="user_id" property="userId" jdbcType="INTEGER" />
    <result column="user_name" property="userName" jdbcType="CHAR" />
    <result column="user_pwd" property="userPwd" jdbcType="CHAR" />
    <result column="company" property="company" jdbcType="BIT" />
  </resultMap>
<!-- 根据用户名查询用户信息 -->
  <select id="selectUser" resultMap="BaseResultMap">
      select user_id, user_name, user_pwd, company
    from guest_user where user_name = #{userName,jdbcType=CHAR}
  </select>
