如何将 FastInfoset 与 JAXWS 结合使用？

Question

根据我能找到的内容，我的代码看起来应该是正确的，但喷出的输出并不表明它正在使用 FastInfoset。我的理解是 Accept 应该表明它可以接受 Fastinfoset 并且响应实际上会使用它，这意味着它不是 text/xml 作为响应类型。知道我做错了什么吗？我用 Google 搜索过，但很难找到有关如何使用 FastInfoset 的详细信息。

    JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
    factory.getInInterceptors().add(new LoggingInInterceptor());
    factory.getOutInterceptors().add(new LoggingOutInterceptor());
    factory.setServiceClass( C360Server.class);
    factory.setAddress("http://localhost:8501/cxfcontroller/cl_v5");
    C360Server client = (C360Server)factory.create();
    ((BindingProvider)client).getRequestContext().put(
        "com.sun.xml.ws.client.ContentNegotiation", "optimistic");

    C360Request requestTrans = new C360Request();
    ... code to fill in the request ...
    C360Response response = client.findContacts( requestTrans );

日志记录似乎并没有表明 FastInfoset 甚至被尝试过：

你知道我做错了什么吗？即使服务器不支持 FastInfoset，我仍然应该在请求中看到尝试的协商，对吗？

Answer 1

答案是我所掌握的有关如何启用它的信息已经过时了。以下内容适用于客户端（大概也适用于服务器端，但我已经启用了 Spring 配置来处理它）。

           JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
           // This enables FastInfoset as the communication protocol
           factory.getInInterceptors().add( new FIStaxInInterceptor() );
           factory.getOutInterceptors().add( new FIStaxOutInterceptor() );
           ... other code to set username, location, etc. goes here.
           client = (C360Server) factory.create();

Answer 2

//Enabling FastInfoset by configuring proxy 
// Enabling FI in pessimistic mode
Map<String, Object> ctxt = ((BindingProvider)proxy).getRequestContext();
ctxt.put(JAXWSProperties.CONTENT_NEGOTIATION_PROPERTY, "pessimistic");

或者

使用系统属性启用 FastInfoset

-Dcom.sun.xml.ws.client.ContentNegotiation=pessimistic
