一、对比Axis2和CXF
jws的发布对java webservice框架产生了巨大的影响,经过大浪淘沙,目前java开发webservice的框架主要包括axis2和cxf。
axis2和cxf都是apache旗下的产品,但是其目的不同,导致webservice开发方法也不一样。两个框架都得到了开发者的支持。有必要对二者进行以下对比。
Axis2 | CXF | |
---|---|---|
目标 | WebService引擎 | 简易的SOA框架,可以作为ESB |
ws* 标准支持 | 不支持WS-Policy | WS-Addressing,WS-Policy, WS-RM, WS-Security,WS-I Basic PRofile |
数据绑定支持 | xmlBeans、JiBX、JaxMe 、JaxBRI、ADB | JAXB, Aegis, XMLBeans, SDO, JiBX |
spring集成 | 不支持 | 支持 |
应用集成 | 困难 | 简单 |
多语言 | 支持C/C++ | 不支持 |
部署 | web应用 | 嵌入式 |
服务监控和管理 | 支持 | 不支持 |
结论:
如果希望以一种一致的方式实现webservice,特别是有跨语言的需求时,应该使用Axis2如果需要在现有的java程序(包括web应用)中增加webservice支持,应该使用CXF从Java6开始,WebService API从Java EE复制到了Java SE。并遵循了一系列的标准,比如JSR181(Web Service 元数据),JSR224(JAX-WS,基于XML的WebService API),JSR67(SAAJ,SOAP附件标准)等。 并分别定义到javax.jws, javax.xml.ws 和 javax.xml.soap包中。
JSR181支持使用标注(annotation)来定义WebService。在javax.jws中主要的标注类包括:
标注 | 说明 |
---|---|
WebService | 将 Java 类标记为实现 Web Service,或者将 Java 接口标记为定义 Web Service 接口 |
WebMethod | 定制Web Service方法 |
WebParam | 定制Web Service方法的参数 |
WebResult | 定制Web Service方法的返回值 |
SOAPBinding | 指定WebService的SOAP映射样式 |
到目前为止,使用的都是标准Java SE中的东西。下面要开始依赖CXF实现一些功能。
首先是服务的发布。CXF不仅支持通过Web容器发布WebService,也可以在嵌入式代码中通过jetty发布WebService。
