java - 套接字异常 : Connection reset - Client Jersey 2. 0 Java 7

Question

我收到与此 link1 类似的错误. 当我通过 REST 发布(客户端到服务器)一个小的 xml 时，一切正常。不幸的是，当我发布一些更大的 xml 时，当连接持续时间超过 10/15 分钟时，我遇到了一个错误。 (我假设这是某种超时)

我更正了我的 SSL 证书，因为它在 link1 中提到 - configureClient() 方法在我的情况下与 link1 中的解决方案相同。

我还添加了 System.setProperty("java.net.preferIPv4Stack", "true"); - 有时它解决连接重置

基本信息:

错误:javax.ws.rs.ProcessingException:java.net.SocketException:连接重置

方法:REST POST

Java 版本:7

引擎: Jersey 2.x

方:客户

系统:Windows 7

我的客户:

   System.setProperty("java.net.preferIPv4Stack" , "true");

RestMethodes restMethodes = new RestMethodes();
ClientConfig config = new ClientConfig();
config = config.property(ClientProperties.CONNECT_TIMEOUT, 0);
config = config.property(ClientProperties.READ_TIMEOUT, 0);

config.property(ClientProperties.SUPPRESS_HTTP_COMPLIANCE_VALIDATION, true);

Client client = configureClient(config);
client.register(HttpAuthenticationFeature.basic(USER, PASS));

WebTarget target = client.target(SERVER_URL + "/bundles/assets");
Invocation.Builder responseInvocation = target.request(MediaType.APPLICATION_JSON);

// My exception is thrown there

Response response = responseInvocation.post(Entity.xml(assetsString)); 

String entity = response.readEntity(String.class);
//entity = jsonPrettyPrinter(entity);

if (entity.isEmpty() || entity.equals("")) {
    log.info("[POST ASSETS] Failed : Response is empty");
}
Response.StatusType codeName = response.getStatusInfo();
int code = response.getStatus();

if (code != 200) {
    log.error("[POST ASSETS] Failed : HTTP error code : " + response.getStatus() + "\n" + entity);
    response.close();
} else {
    log.info("[POST ASSETS] RESPONSE CODE ID : " + code + " CODE NAME : " + codeName);
    log.info("[POST ASSETS] RESPONSE : " + entity);
    response.close();
}
client.close();

我的错误

编辑:

我忘了说我设法通过 CURL 从 bash 发出了无限超时的请求并保持 Activity 状态，所以这不应该是服务器问题。 CURL REST 帖子用了 24 分钟。我的 Java 客户端在 15 分钟后抛出连接重置。在我看来，这可能是我的错。

尽管您的客户端似乎配置良好，但您正面临超时问题。此超时可能由任何防火墙、代理、负载平衡器或服务器本身引起，如果它在应用程序服务器前面运行 Web 服务器(如 Apache)。请检查您的客户端和应用程序服务器之间的内容，并在各处相应地设置超时。

这并不意味着您不能对客户端本身做任何事情，但解决那里要困难得多。 在 Windows 上，您需要启用 TCP keep-alives ， 第一的。 之后，根据Client Transport你正在使用，我们将尝试将 TCP keep-alives 添加到底层工厂构建的套接字中，这与我们在 Axis clients 上知道的类似。 .此解决方案对您而言更耗时。
