篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CXF 中自定义SOAPHeader相关的知识，希望对你有一定的参考价值。

Interceptor是CXF架构中一个很有特色的模式。你可以在不对核心模块进行修改的情况下，动态添加很多功能。这对于CXF这个以处理消息为中心的服务框架来说是非常有用的，CXF通过在Interceptor中对消息进行特殊处理，实现了很多重要功能模块，例如：日志记录，Soap消息处理，消息的压缩处。简单的说，可以在收到请求后，还未进行业务处理前，进行处理。或者在请求包发送前，进行报文的处理。

Interceptor

定义两个方法，一个处理消息 handleMessage，一个是处理错误 handleFault。

InterceptorChain

单个的Interceptor功能有限，CXF要实现一个SOAP消息处理，需要将许许多多的Interceptor组合在一起使用。因此设计了 InterceptorChain，在我看了InterceptorChain就像是一个Interceptor的小队长。小队长有调配安置Interceptor的权力（add，remove），也有控制消息处理的权力（doInterceptor，pause，resume，reset，abort），同时也有交付错误处理的权力（ {get|set}FaultObserver）。更有意思的是为灵活控制Interceptor的处理消息顺序（doInterceptStartingAt，doInterceptorStartingAfter），这也是InterceptorChain比较难理解的地方。

Fault

定义了CXF中的错误消息。

InterceptorProvider

　　这里定义了Interceptor的后备保障部队。我们可以在InterceptorProvider中设置In，Out，InFault，OutFault 后备小分队，添加我们所希望添加的Interceptor。而InterceptorChain会根据这些后备小分队，组建自己的小分队实例，完成具体的作战功能任务。

AbstractAttributedInterceptorProvider

InterceptorProvider实现的抽象类，由于这个类来继承了HashMap，我们可以像这个类中存储一些属性信息。

AbrstractBasicInterceptorProvider

与AbstractAttributedInterceptorProvider不同，这个Interceptor只是简单实现了InterceptorProvider的功能，并不提供对其属性存储的扩展。

Message

由于Interceptor是针对Message来进行处理的，当你打开Message这个类文件时，你会发现在Message中定义了很多常量，同时你还可以从Message中获取到很多与Message操作相关的信息。可以获取设置的对象有InterceptorChain Exchange Destination，还有获取设置Content的泛型接口，是不是感觉Message和Bus差不多，都成了大杂货铺，一切与消息处理相关的信息都可以放在Message中。
