JAX-WS interceptors (also called handlers) are used to weave in aspects of the request in a transparent way. Example of this are logging or requests/responses, adding security headers to the message, encryption, compression, etc. A single interceptor can manipulate either the logical payload (content) of the message or the protocol of the message, but cannot do both.
JAX-WS 拦截器（也称为处理程序）用于以透明的方式编织请求的各个方面。这方面的示例是日志记录或请求/响应、向消息添加安全标头、加密、压缩等。单个拦截器可以操作消息的逻辑负载（内容）或消息的协议，但不能同时操作。
See herefor the introductory documentation on them.

in addition to a Handler in JAX-WS, the RI also provides the Tube concept. It is pretty close to the Filter concept in a Servlet API, as such you can access and manipulate entire in/out packet for a service and a client alike.
除了 JAX-WS 中的 Handler 之外，RI 还提供了 Tube 概念。它非常接近 Servlet API 中的过滤器概念，因此您可以访问和操作服务和客户端的整个输入/输出数据包。
I find it more handy for general purposes, like logging of messages and prevalidation of soap headers, etc just because I dont have to attach a @HandlerChain on every web-service. See link.
我发现它对于一般用途更方便，例如记录消息和预验证soap标头等，因为我不必在每个网络服务上附加@HandlerChain。见链接。
