Java Web服務框架：Apache CXF
Apache CXF一個開源的Service框架，它實現了JCP與Web Service中一些重要標準。CXF簡化了構造，集成，面 向服務架構(SOA)業務組件與技術的靈活復用。在CXF中，Service使用WSDL標準定義并能夠使用各種不同的消息 格式(或binding)和網絡協議(transports)包括SOAP、XML（通過HTTP或JMS）進行訪問。CXF同樣支持多種model 如：JAX-WS，JBI，SCA和CORBA service。CXF設計成可靈活部署到各種容器中包括Spring-based，JBI，SCA， Servlet和J2EE容器。
CXF includes a broad feature set, but it is primarily focused on the following areas:
- Web Services Standards Support: CXF supports a variety of web service standards including SOAP, the WS-I Basic Profile, WSDL, WS-Addressing, WS-Policy, WS-ReliableMessaging, WS-Security, WS-SecurityPolicy, WS-SecureConverstation, and WS-Trust (partial).
- Frontends: CXF supports a variety of "frontend" programming models.
CXF implements the JAX-WS APIs. CXF JAX-WS support includes some extensions to the standard that make it significantly easier to use, compared to the reference implementation: It will automatically generate code for request and response bean classes, and does not require a WSDL for simple cases.
It also includes a "simple frontend" which allows creation of clients and endpoints without annotations. CXF supports both contract first development with WSDL and code first development starting from Java.
For REST, CXF also supports a JAX-RS frontend.
- Ease of use: CXF is designed to be intuitive and easy to use. There are simple APIs to quickly build code-first services, Maven plug-ins to make tooling integration easy, JAX-WS API support, Spring 2.x XML support to make configuration a snap, and much more.
- Binary and Legacy Protocol Support: CXF has been designed to provide a pluggable architecture that supports not only XML but also non-XML type bindings, such as JSON and CORBA, in combination with any type of transport.
