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。
