java - 泽西客户端创建错误

Question

经过一个小时的交通后，我有以下异常，我必须检查什么？ 此代码可在一个小时内正常运行。我认为某些系统文件夹已满。

异常显示"Client client = Client.create(config);"代码语句无法执行。

private static boolean callFileDownloadDelete(User user, String fileUrl, boolean isDownloadCompleted) {
    ClientConfig config = new DefaultClientConfig();
    Client client = Client.create(config);
    client.addFilter(new HTTPBasicAuthFilter(user.getUserName(), user.getPassword()));

我正在模拟客户端-服务器交互，就像真实用户执行操作一样，我是否必须为每个用户创建一个客户端实例，或者是否应该在每次执行操作时创建客户端？

我在消息中遇到了类似的错误:

WARNING: Cannot create temporary files. Multipart attachments will be limited to 4096 bytes. java.io.IOException: No such file or directory

这是因为文件夹${APACHE_HOME}/temp不存在。

创建丢失的文件夹并重新启动 tomcat 后，错误消息停止显示。
