问题

基于Apache HttpComponents构建的基于Java的服务器应如何组装并发送带有附件（SWA）响应的大型SOAP？

问题详情

Apache HttpClient Java API不支持分块多部分HttpEntity实例。当SWA响应中的附件很大（> 2 MiB）时，向模拟服务器发出SOAP请求的客户端（特别是基于Apache的Java客户端正在抛出org.apache.http.NoHttpResponseExceptions）失败。传输小附件时不会出现任何例外情况。 HTTP Content-Length标头是正确的。

用例

能够传输任意内容长度的SWA响应的多线程SOAP服务器

平台

Java 8 64b

必需的图书馆

HttpCore v4.4.6 + HttpMime v4.5.3

错误复制

使用HttpCore v4.4.6和HttpMime v4.5.3库构建示例源代码（HttpMime是HttpClient项目的一部分）。
以足够大（> 2 MiB）＆＃34; random.png.gz＆＃34;运行程序。二进制文件。
通过某个第三方客户端向服务器发送任意HTTP POST请求。由于它是具有精确日志记录的基于Apache的Java客户端，因此建议使用SoapUI。 NB：无法接收服务器生成的大型多部分结果。
