使用cxf3.0.4搭建webservice服务需要的最精简jar包

2024-11-11 来源:个人技术集锦

        网上看了百度了好长时间,头都大了,还是没有把想要的最简jar包找到,不是jar仍然很多,就是jar包少了,导致报错。无奈之下,自己花了一个下午,采用用逆推法,总结了下cxf3.0.4结合spring搭建webservice服务端的框架必需的最少jar包。

      方法很笨,但是很有效:直接先加载cxf3.0.4中lib下的所有jar包,结合spring搭建一个最简单的webservice服务框架。然后逐个删除项目下的cxf相关的jar包。

     下面是测试结果,只列出报错了的测试:

1、org.apache.catalina.LifecycleException: A child container failed during start
缺少:cxf-core-3.0.4.jar(最核心的包,不多说)


2、java.lang.ClassNotFoundException: org.apache.cxf.binding.soap.SoapBindingConfiguration
缺少:cxf-rt-bindings-soap-3.0.4.jar       (soap协议)

3、org.apache.cxf.jaxb.JAXBDataBinding:
缺少:cxf-rt-databinding-jaxb-3.0.4.jar      


4、加载Application文件时出现Unable to locate Spring NamespaceHandler for XML schema namespace
     [http://cxf.apache.org/jaxws]

缺少:cxf-rt-frontend-jaxws-3.0.4.jar    (frontend 前置的意思,你懂的)

5、org/apache/cxf/frontend/spring/ClientProxyFactoryBeanDefinitionParser错误:
缺少:cxf-rt-frontend-simple-3.0.4.jar


6、class path resource [META-INF/cxf/cxf-servlet.xml] cannot be opened because it does not exist
缺少:cxf-rt-transports-http-3.0.4.jar


7、org.apache.cxf.BusException: No DestinationFactory was found for the namespace http://cxf.apache.org/transports/udp.
缺少:cxf-rt-transports-udp-3.0.4.jar


8、org.apache.cxf.ws.discovery.internal.WSDiscoveryServiceImpl startup
警告: Could not start WS-Discovery Service.
javax.xml.ws.WebServiceException: java.lang.NullPointerException
不能初始化配置的bean服务,也就是运行到<jaxws:server>时出错

缺少:cxf-rt-ws-addr-3.0.4.jar

9、java.lang.ClassNotFoundException: org.apache.cxf.ws.policy.AssertionInfoMap
缺少:cxf-rt-ws-policy-3.0.4.jar        


10、java.lang.ClassNotFoundException: org.apache.cxf.wsdl.service.factory.ReflectionServiceFactoryBean
缺少:cxf-rt-wsdl-3.0.4.jar

11、java.lang.ClassNotFoundException: org.apache.neethi.AssertionBuilderFactory
缺少:neethi-3.0.3.jar

12、java.lang.ClassNotFoundException: org.slf4j.LoggerFactory
缺少:slf4j-api-1.7.9.jar

13、java.lang.ClassNotFoundException: org.apache.ws.commons.schema.resolver.URIResolver
缺少:xmlschema-core-2.2.1.jar


所以,总结cxf3.0.4框架必需的包为:
cxf-core-3.0.4.jar
cxf-rt-bindings-soap-3.0.4.jar
cxf-rt-databinding-jaxb-3.0.4.jar
cxf-rt-frontend-jaxws-3.0.4.jar
cxf-rt-frontend-simple-3.0.4.jar
cxf-rt-transports-http-3.0.4.jar
cxf-rt-transports-udp-3.0.4.jar
cxf-rt-ws-addr-3.0.4.jar
cxf-rt-wsdl-3.0.4.jar
cxf-rt-ws-policy-3.0.4.jar
cxf-rt-wsdl-3.0.4.jar
neethi-3.0.3.jar
slf4j-api-1.7.9.jar
xmlschema-core-2.2.1.jar

注意:这里不包括spring依赖包和commoms下的jar包


引入CXF Bean定义如下,早期的版本中使用,如果是servlet引入的话则下面三句不用了,因为框架引入了 
配置文件中不需要:
 <import resource="classpath:META-INF/cxf/cxf.xml"/>
 <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
 <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />

 <!-- scope="singleton"单例 -->
   <bean id="userServiceBean" class="com.winit.webservice.UserWebService">
   </bean>
    <!-- 注意下面的address,这里的address的名称就是访问的WebService的name --> 
    <jaxws:server id="userService" serviceClass="com.winit.webservice.IUserWebService" address="/Users">    
	    <jaxws:serviceBean>         
	        <!-- 要暴露的 bean 的引用 -->        
	        <ref bean="userServiceBean"/>     
	    </jaxws:serviceBean>     
   </jaxws:server>

web.xml中添加cxf的servlet

  <servlet>  
      <servlet-name>CXFService</servlet-name>  
      <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>  
  </servlet>          
  <servlet-mapping>  
      <servlet-name>CXFService</servlet-name>  
      <url-pattern>/webservice/*</url-pattern>  
  </servlet-mapping> 


项目名是 WebAdvanced,服务启动后,访问链接:
http://localhost:8080/WebAdvanced/webservice/Users?wsdl。说明发布的webservice服务成功。

最后,“尽信书则不如无书”,当你无路可走,没有好的思路时,最笨的方法,往往是最直接有效的方法。
