如何设置JAX-WS Web服务客户端的超时？ [英] How do I set the timeout for a JAX-WS webservice client?

问题描述

我已经使用JAXWS-RI 2.1基于WSDL为我的Web服务创建了一个接口。我可以与Web服务进行交互没有问题，但是无法指定向Web服务发送请求的超时。如果由于某种原因它没有响应客户似乎永远旋转它的轮子。

I've used JAXWS-RI 2.1 to create an interface for my web service, based on a WSDL. I can interact with the web service no problems, but haven't been able to specify a timeout for sending requests to the web service. If for some reason it does not respond the client just seems to spin it's wheels forever.

狩猎已经显示我应该尝试做这样的事情：

Hunting around has revealed that I should probably be trying to do something like this:

((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.ws.request.timeout", 10000);
((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.ws.connect.timeout", 10000);

我还发现，根据您拥有的JAXWS-RI版本，您可能需要设置这些属性改为：

I also discovered that, depending on which version of JAXWS-RI you have, you may need to set these properties instead:

((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 10000);
((BindingProvider)myInterface).getRequestContext().put("com.sun.xml.internal.ws.connect.timeout", 10000);

我遇到的问题是，无论上述哪一项是正确的，我都不知道 where 我可以这样做。我所拥有的只是 服务 子类，它实现了自动生成的webservice接口，并且实现了这一点，如果WSDL没有响应，那么设置它已经太晚了属性：

The problem I have is that, regardless of which of the above is correct, I don't know where I can do this. All I've got is a Service subclass that implements the auto-generated interface to the webservice and at the point that this is getting instanciated, if the WSDL is non-responsive then it's already too late to set the properties:

MyWebServiceSoap soap;
MyWebService service = new MyWebService("http://www.google.com");
soap = service.getMyWebServiceSoap();
soap.sendRequestToMyWebService();

有人能指出我正确的方向吗？！

Can anyone point me in the right direction?!

推荐答案

我知道这已经过时了，并在其他地方得到了解答，但希望这会让这个结束。我不确定你为什么要动态下载WSDL但系统属性：

I know this is old and answered elsewhere but hopefully this closes this down. I'm not sure why you would want to download the WSDL dynamically but the system properties:

sun.net.client.defaultConnectTimeout (default: -1 (forever))
sun.net.client.defaultReadTimeout (default: -1 (forever))

应该适用于所有读取并使用JAX-WS使用的HttpURLConnection进行连接。如果从远程位置获取WSDL，这应该可以解决您的问题 - 但本地磁盘上的文件可能更好！

should apply to all reads and connects using HttpURLConnection which JAX-WS uses. This should solve your problem if you are getting the WSDL from a remote location - but a file on your local disk is probably better!

接下来，如果要设置超时对于特定服务，一旦您创建了代理，您需要将其转换为BindingProvider（您已经知道），获取请求上下文并设置您的属性。在线JAX-WS文档是错误的，这些是正确的属性名称（好吧，它们适用于我）。

Next, if you want to set timeouts for specific services, once you've created your proxy you need to cast it to a BindingProvider (which you know already), get the request context and set your properties. The online JAX-WS documentation is wrong, these are the correct property names (well, they work for me).

MyInterface myInterface = new MyInterfaceService().getMyInterfaceSOAP();
Map<String, Object> requestContext = ((BindingProvider)myInterface).getRequestContext();
requestContext.put(BindingProviderProperties.REQUEST_TIMEOUT, 3000); // Timeout in millis
requestContext.put(BindingProviderProperties.CONNECT_TIMEOUT, 1000); // Timeout in millis
myInterface.callMyRemoteMethodWith(myParameter);

当然，这是一种可怕的做事方式，我会创建一个很好的工厂来生产这些绑定提供程序，可以注入所需的超时。

Of course, this is a horrible way to do things, I would create a nice factory for producing these binding providers that can be injected with the timeouts you want.
