1、数据库连接字符串后添加参数（若是oracle不需要）：

&allowMultiQueries=true

<update id="updateUserOrder" parameterType="map">
		<foreach collection="entitys" item="entity" separator=";">
			update p_order pr
			<set>
				pr.if_sall = pr.id,
				pr.if_use = pr.id,
				<if test="entity.users_telphone != null and entity.users_telphone != ''">
					pr.users_telphone = #{entity.users_telphone},
				</if>
				pr.updatetime = #{entity.updatetime}
			</set>
			where pr.id = #{entity.id}
		</foreach>
	</update>
