运行oss的demo时遇到问题

[YuanZhangAly]

你好，我在运行oss 的 demo时遇到了一些问题，运行一段时间后会抛出一个异常，并且程序会终止运行。

根据异常能判断出是oss的endpoint配置的有问题，但是我以各种方式配置了很多次都没有解决，能否帮忙解决一下这个异常？我会将异常信息以及我的相关配置贴出来。

以下是我对endpoint做的配置：

    <property>
        <name>fs.oss.endpoint</name>
        <value>oss-endpoint-address</value>
        <description>oss-cn-beijing.aliyuncs.com</description>
<!--        <description>oss-cn-beijing</description>-->
<!--        <description>beijing</description>-->
    </property>

以下是异常信息：
