解决：resultMap="userlists">和 resultMap id="userlist"> 对应不上。

原：

<mapper namespace="com.smbms.pojo.UserMapper">
  <!-- 下面定义的映射语句是用于Mybatis/Spring整合练习。 -->
  <resultMap type="com.smbms.pojo.User" id="userlist">
    <result property="userRoleName" column="roleName"/>
  </resultMap>
  <select id="getUserList" parameterType="com.smbms.pojo.User" resultMap="userlists">
    select u.* ,r.roleName from smbms_user,u smbms_role r
    where u.userName like CONCAT('%',#{uesrName},'%')
    and u.userRole = #{userRole} and u.userRole = r.id
  </select>  
 </mapper>

改：userlist 或者 userlists。
