Java JAX-WS web-service client: how log request & response xml?
提问by EugeneP
I created an implementation of LoggingHandlerthat implements SOAPHandler<SOAPMessageContext>
我创建了一个LoggingHandler实现SOAPHandler<SOAPMessageContext>
It should log whenever handleMessagetriggers (and it is never called in my case)
它应该在handleMessage触发时记录（在我的情况下它永远不会被调用）
MyService service = new MyService();
MyServicePort port = service.getPortType();
now I try this:
现在我试试这个：
BindingProvider bindingProvider = (BindingProvider)port;
bindingProvider.getBinding().getHandlerChain().add(new LoggingHandler());
I do not see any request / response xml though.
虽然我没有看到任何请求/响应 xml。
Can you suggest any solution? Maybe there's another way to see output and request XML?
你能提出任何解决方案吗？也许还有另一种方式来查看输出和请求 XML？

It starts working if you use this method:
如果您使用此方法，它将开始工作：
binding.setHandlerChain(handlerList);
So, first initialize this list with
所以，首先初始化这个列表
binding.getHandlerChain();
then add your element to the list and after all
然后将您的元素添加到列表中，毕竟
setHandlerChain();

you can add a logger in you log4j.xml file :
您可以在 log4j.xml 文件中添加记录器：
<!-- Log WebService's inputs and outputs -->
<logger name="org.apache.cxf.interceptor">
<level value="INFO" />
<appender-ref ref="[YOUR_LOGGER]" />
</logger>

If anyone is wondering the 'why' of @EugeneP excellent answer.
如果有人想知道@EugeneP 优秀答案的“为什么”。
In the Interface javax.xml.ws.Binding, there is the following comment.
在接口 javax.xml.ws.Binding 中，有如下注释。
/**
* Gets a copy of the handler chain for a protocol binding instance.
* If the returned chain is modified a call to
<code>setHandlerChain</code>
* is required to configure the binding instance with the new chain.
*
* @return java.util.List<Handler> Handler chain
*/
public java.util.List<javax.xml.ws.handler.Handler> getHandlerChain();
So the getHandlerChain() method returns a copy of the List not the list itself. So you have to use setHandlerChain to update the actual List.
因此 getHandlerChain() 方法返回列表的副本而不是列表本身。所以你必须使用 setHandlerChain 来更新实际的 List。
