今天我们来讲下如何用Spring来整合CXF,来发布WebService服务;
给下官方文档地址:http://cxf.apache.org/docs/writing-a-service-with-spring.html
根据官方文档。我们把前面的实例用Spring整合CXF来处理下。会简化很多;
首先我们来建一个Maven项目 WebService_CXF
建好项目第一步,我们打开pom.xml
我们来添加下Spring支持:

<!-- 添加cxf支持 --> < dependency > < groupId >org.apache.cxf</ groupId > < artifactId >cxf-core</ artifactId > < version >3.1.5</ version > </ dependency > < dependency > < groupId >org.apache.cxf</ groupId > < artifactId >cxf-rt-frontend-jaxws</ artifactId > < version >3.1.5</ version > </ dependency > < dependency > < groupId >org.apache.cxf</ groupId > < artifactId >cxf-rt-transports-http</ artifactId > < version >3.1.5</ version > </ dependency > |
我们在项目里添加下 applicationContext.xml spring配置文件 我们要额外添加下命名路径,因为我们要用新的标签;

这里的我是参考官方文档上,添加了 jaxws支持。。大家直接贴下即可;
然后我们再导入下cxf里的一些bean配置,参考官方文档:
1
2
|
< import resource = "classpath:META-INF/cxf/cxf.xml" /> < import resource = "classpath:META-INF/cxf/cxf-servlet.xml" /> |
(我看了cxf核心包,其实质疑偶cxf.xml,没有cxf-servlet.xml 估计是兼容前面版本)
我们把前面的类贴到我们这个项目了;
这里的HelloWorldImpl类上,我们加一个 @Component("helloWorld")
Spring配置文件里,我加下扫描:
1
2
|
<!-- 自动扫描 --> < context:component-scan base-package = "com.java1234.webservice" /> |
前面搞完后,我们在处理下web.xml文件 首先启动的时候,必须加载Spring:

<!-- Spring配置文件 --> < context-param > < param-name >contextConfigLocation</ param-name > < param-value >classpath:applicationContext.xml</ param-value > </ context-param > <!-- Spring监听器 --> < listener > < listener-class >org.springframework.web.context.ContextLoaderListener</ listener-class > </ listener > |
然后我们要定义一个Servlet,主要是处理WebService请求:
1

|
< servlet > < servlet-name >CXFServlet</ servlet-name > < servlet-class >org.apache.cxf.transport.servlet.CXFServlet</ servlet-class > </ servlet > < servlet-mapping > < servlet-name >CXFServlet</ servlet-name > < url-pattern >/webservice/*</ url-pattern > </ servlet-mapping > |
这里的话,我们所有的 /webservice请求,都交给CXFServlet类处理;
最后一步,我们在Spring配置文件里,定义下webservice接口发布:
1
2
3
4
5
|
<!-- 定义服务提供者 --> < jaxws:endpoint implementor = "#helloWorld" address = "/HelloWorld" ></ jaxws:endpoint > |
这里implementor指定webservice接口实现类
address是具体的接口路径
最终完整的applicationContext.xml配置文件如下:

我们来启动下项目,然后访问 http://localhost:8080/WebService_CXF/webservice/
效果如下:
说明已经webservice接口已经发布成功了;
我们可以访问具体的接口: http://localhost:8080/WebService_CXF/webservice/HelloWorld?wsdl
效果如下:
