在项目中集成CXF2.x框架的一点心得

    为了能够在项目中正常使用CXF2.x框架提供WebService功能，至少需要以下jar文件：

          asm-2.2.3.jar
          cglib-nodep-2.1_3.jar
          cxf-2.1.2.jar
          cxf-manifest.jar
          FastInfoset-1.2.2.jar
          geronimo-annotation_1.0_spec-1.1.1.jar
          geronimo-jaxws_2.1_spec-1.0.jar
          geronimo-stax-api_1.0_spec-1.0.1.jar
          geronimo-ws-metadata_2.0_spec-1.1.2.jar
          jaxb-api-2.1.jar
          jaxb-impl-2.1.7.jar
          neethi-2.0.4.jar
          saaj-api-1.3.jar
          wsdl4j-1.6.2.jar
          wstx-asl-3.2.4.jar
          xml-resolver-1.2.jar
          XmlSchema-1.4.2.jar

 

    作者的项目主要应用Spring-2.0.7、hibernate-3.2.5技术框架，在集成CXF时老是抛出以下异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cxfService': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.visit(IILjava/lang/String;Ljava/lang/String;Ljava/lang/String;[Ljava/lang/String;)V
Caused by: 
java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.visit(IILjava/lang/String;Ljava/lang/String;Ljava/lang/String;[Ljava/lang/String;)V
	at org.apache.cxf.jaxws.WrapperClassGenerator.generatePackageInfo(WrapperClassGenerator.java:227)
	at org.apache.cxf.jaxws.WrapperClassGenerator.createWrapperClass(WrapperClassGenerator.java:171)
	at org.apache.cxf.jaxws.WrapperClassGenerator.generate(WrapperClassGenerator.java:132)
。。。。。。

    在网上查找相关资料，经过反复尝试，终于发现问题的所在。原来

        hibernate-3.2.5需要asm-1.x.jar、cglib-2.1.3.jar版本的jar文件，

        Spring-2.0.7需要asm-2.2.3.jar，

        CXF-2.x需要asm-2.2.3.jar。

这样导致了asm jar文件发生了冲突。为了解决冲突的问题，需要将asm-1.x.jar、cglib-2.1.3.jar版本的jar文件去掉，用Spring提供的cglib-nodep-2.1_3.jar文件替代即可解决此问题。

 

下面是主要的配置信息：

    一、在web.xml文件中的配置

<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>
		/WEB-INF/config/applicationContext.xml,
		/WEB-INF/config/beans-cxf.xml
	</param-value>
</context-param>

<servlet>
	<servlet-name>cxf</servlet-name>
	<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
	<load-on-startup>2</load-on-startup>
</servlet>

<servlet-mapping>
	<servlet-name>cxf</servlet-name>
	<url-pattern>/cxf/*</url-pattern>
</servlet-mapping>

   二、java接口

 

@WebService
public interface CXFService {
	public String sayHello(String username);
}

 

   三、接口实现类

@WebService (endpointInterface="com.cjm.webservice.cxf.CXFService")
public class CXFServiceImpl implements CXFService {
	public String sayHello(String username) {
		if(username==null || username.length()==0){
			return "Hello Guest";
		}else{
			return "Hello " + username;
		}
	}
}

   四、服务端相关bean的配置

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
		http://cxf.apache.org/jaxws 
		http://cxf.apache.org/schemas/jaxws.xsd">

    <import resource="classpath:META-INF/cxf/cxf.xml" />
    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
    
    <bean id="cxfServiceImpl" class="com.cjm.webservice.cxf.CXFServiceImpl"/>
    
    <jaxws:endpoint id="cxfService" implementor="#cxfServiceImpl" address="/cxfService" />    
</beans>

   五、在客户端调用WebService业务方法的范例

        1、在spring环境下的调用

              生成cxf环境下的接口类的命令：wsdl2java -p com.travelsky.agentsky.ws.client http://localhost:8091/inner/ws/marketInfoWS?wsdl

 

              1）bean的配置

<bean id="client" class="com.cjm.webservice.cxf.CXFService"
        factory-bean="clientFactory" factory-method="create" />

<bean id="clientFactory"
        class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
        <property name="serviceClass" value="com.cjm.webservice.cxf.CXFService" />
        <property name="address"
            value="http://localhost:8888/spring2/cxf/cxfService" />
</bean>

             2）业务方法调用

CXFService cxf = (CXFService)SpringContextUtil.getBean("client");
String ret = cxf.sayHello("Raymond.Chen");

 

      2、在非spring环境下的调用

//客户端类生成命令：
//wsdl2java -p com.travelsky.monica.ws.client http://localhost:9081/monicaServices/ws/monicaServices?wsdl

List<String> passengerIds = new ArrayList<String>();
passengerIds.add("1n");
passengerIds.add("3n");

List<String> airCodes = new ArrayList<String>();
airCodes.add("cz");
airCodes.add("ca");

JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(MonicaServices.class); //服务接口类
factory.setAddress("http://localhost:9081/monicaServices/ws/monicaServices"); //服务地址
System.setProperty("org.apache.cxf.bus.factory", "org.apache.cxf.bus.CXFBusFactory");
MonicaServices client = (MonicaServices) factory.create();
String s = client.generatePnrContent("CAN001", "12345", passengerIds, airCodes, true);
