使用JAXRPC-RI Web服务客户端时如何设置连接超时？

问题描述

我正在使用一些遗留组件，我们使用JAXRPC-RI（参考实现）库构建的一些客户端代码与SOAP Web服务（我绝对，非常厌恶的技术）进行交互。 / p>

我有兴趣能够使用存根设置超时，以便万一Web服务器在X秒内没有回复，应用程序不会在那里设置永远等待回复。

我正在使用Apache Axis生成的客户端/存根，您只需使用 org。 apache.axis.client.Stub.setTimeout（）设置超时。

对于我的生活，我无法弄清楚如何使用使用JAXRPC-RI创建的存根时设置超时：

• 我实例化的端口类扩展 com。 sun.xml.rpc.client.StubBase 并实现 javax.xml.rpc.Stub 和 com.sun.xml .rpc.spi.runtime.StubBase 。


• The Ja没有这些类的vaDocs提到任何类型的超时或方法来执行此操作。


• 尝试代码如 stub._setProperty（axis.connection.timeout，1000 ）; 在运行时导致异常： javax.xml.rpc.JAXRPCException：Stub无法识别属性：axis.connection.timeout

有没有人对使用JAXRPC-RI客户端时如何设置/强制执行超时有任何想法？甚至可能吗？

解决方案

您可能有运气设置属性，例如 sun.net.client。 defaultConnectTimeout 或 sun.net.client.defaultReadTimeout ，但这会引入系统范围的超时。

在代码中，使用字符串设置属性值：

  System.setProperty（sun.net.client .defaultConnectTimeout，1000）; 
 System.setProperty（sun.net.client.defaultReadTimeout，1000）; 
  

对于快速测试，设置环境变量可能更容易 JAVA_OPTS 或使用命令行：

  java -Dsun.net.client.defaultConnectTimeout =1000 ... 
  

I'm working with a bit of a legacy component in which we interact with a SOAP web service (a technology which I absolutely, positively abhor) using some client code built using the JAXRPC-RI (reference implementation) library.

I'm interested in being able to set a timeout with the stubs so that in case the web services server does not reply within X seconds, the application isn't setting there forever waiting for a response.

I'm using to working with clients/stubs generated by Apache Axis, in which you can simply use org.apache.axis.client.Stub.setTimeout() to set a timeout.

For the life of me I can't figure out how to set a timeout when using Stubs created with JAXRPC-RI:

• The port class I am instantiating extends com.sun.xml.rpc.client.StubBase and implements javax.xml.rpc.Stub and com.sun.xml.rpc.spi.runtime.StubBase.
• The JavaDocs for none of these classes mention any sort of timeout or method to do this.
• Trying code like stub._setProperty("axis.connection.timeout", 1000); results in an exception at runtime: javax.xml.rpc.JAXRPCException: Stub does not recognize property: axis.connection.timeout

Does anyone have any ideas on how to set/enforce a timeout when using a JAXRPC-RI client? Is it even possible?

解决方案

You may have luck setting properties such as sun.net.client.defaultConnectTimeout or sun.net.client.defaultReadTimeout, though that would then introduce a system-wide timeout.

In code the properties values are set using Strings:

System.setProperty("sun.net.client.defaultConnectTimeout", "1000");
System.setProperty("sun.net.client.defaultReadTimeout", "1000");

For a quick test, it might be easier to set the environment variable JAVA_OPTS or use the command line:

java -Dsun.net.client.defaultConnectTimeout="1000" ...
