我正在使用分布式 OSGi 和 Zookeeper 构建分布式应用程序。该应用程序应该在 Felix 和 Equinox 上运行。我将我的服务注册为 JAX-WS Web 服务，BundleContext.registerService(...)并使用ServiceTracker<S,T>. 所以所有的服务处理都是由 OSGi 框架完成的。每个服务调用都会进行一些计算，因此在响应调用者之前需要一些时间。

问题是java.net.SocketTimeoutException: Read timed out当服务调用花费超过 60 秒时我会遇到异常。因此，似乎默认超时为 60 秒。有人知道我可以如何配置 OSGi 框架使用的超时吗？

这是完整的堆栈跟踪：

我解决了这个问题。我正在使用 cxf-dosgi-ri-singlebundle-distribution-1.2.jar 打开文件 /META-INF/cxf/cxf.xml 并添加一些内容：

xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
xsi:schemaLocation="......
http://cxf.apache.org/transports/http/configuration
http://cxf.apache.org/schemas/configuration/http-conf.xsd"

<http-conf:conduit name="*.conduit">   
    <http-conf:client ConnectionTimeout="10000" ReceiveTimeout="20000"/>  
</http-conf:conduit>

That's ok now!
