我有一个在Jetty上运行的REST Web服务.我想编写一个
Java客户端,它使用相同的Web连接将大量文档分块到该休息服务.
我能够在这里建立一个基于Iterator的流媒体方法：
Sending a stream of documents to a Jersey @POST endpoint
除非您设置clientConfig.property(ClientProperties.REQUEST_ENTITY_PROCESSING,RequestEntityProcessing.CHUNKED),否则这不起作用;因为内容长度未知.
虽然有些工作,但分块转移似乎丢失了一些文件.例如：
num_docs 500000 numFound 499249
也许它发送的块像：
{some：doc},{some：doc},{some：do
所以我每次都在输掉一些？更新：我错了.
我该怎么做呢？还有什么想法可能会发生什么？
ClientConfig clientConfig = new ClientConfig();
clientConfig.property(ClientProperties.CONNECT_TIMEOUT,(int)TimeUnit.SECONDS.toMillis(60));
clientConfig.property(ClientProperties.REQUEST_ENTITY_PROCESSING,RequestEntityProcessing.CHUNKED);
clientConfig.property(ClientProperties.ASYNC_THREADPOOL_SIZE,100);
clientConfig.property(ApacheClientProperties.CONNECTION_MANAGER,HttpClientFactory.createConnectionManager(name,metricRegistry,configuration));
ApacheConnectorProvider connector = new ApacheConnectorProvider();
clientConfig.connectorProvider(connector);
clientConfig.register(new ClientRequestFilter() {
@Override
public void filter(ClientRequestContext requestContext) throws IOException {
List<Object> orig = requestContext.getHeaders().remove(HttpHeaders.CONTENT_LENGTH);
if (orig != null && !orig.isEmpty()) {
requestContext.getHeaders().addAll("Length",orig);
}
}
});
clientConfig.register(new ClientRequestFilter() {
@Override
public void filter(ClientRequestContext requestContext) throws IOException {
if (requestContext.getMediaType() != null &&
requestContext.getMediaType().getType() != null &&
requestContext.getMediaType().getType().equalsIgnoreCase("multipart")) {
final MediaType boundaryMediaType = Boundary.addBoundary(requestContext.getMediaType());
if (boundaryMediaType != requestContext.getMediaType()) {
requestContext.getHeaders().putSingle(HttpHeaders.CONTENT_TYPE,boundaryMediaType.toString());
}
if (!requestContext.getHeaders().containsKey("MIME-Version")) {
requestContext.getHeaders().putSingle("MIME-Version","1.0");
}
}
}
});
