Apache CXF 整合Spring

本例是Apache CXF 整合Spring，并将工程服务发布到 Tomcat 的一个例子，主要是参考官方的实现方式。实现2个WebService方法，一个是返回String类型的，一个是返回List类型方式的。
一、创建一个 Java Web 工程，目录最终的结构如下图，下面我们将遂一说明：
二、把我们要用到的jar包全部放到lib目录下。
三、修改web.xml文件，整合CXF。
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>HelloSpringCXF</display-name> <servlet> <description>HelloSpringCXF</description> <display-name>cxf</display-name> <servlet-name>cxf</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>cxf</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <session-config> <session-timeout>60</session-timeout> </session-config> </web-app>
四、创建服务器端代码：
4.1 接口HelloWorld 会用到一个@WebService注释，说明是WebService接口：
package com.yao.spring.service; import java.util.List; import javax.jws.WebService; @WebService public interface HelloWorld { String sayHi(String text); List<String> getListString(); }
package com.yao.spring.service; import java.util.ArrayList; import java.util.List; import javax.jws.WebService; @WebService(endpointInterface = "com.yao.spring.service.HelloWorld") public class HelloWorldImpl implements HelloWorld { public String sayHi(String text) { System.out.println("sayHi called"); return "Hello " + text; } @Override public List<String> getListString() { List<String> lists = new ArrayList<String>(); lists.add("AA"); lists.add("BB"); lists.add("CC"); return lists; } } 3.3 在 WEB-INF 下 创建 cxf-servlet.xml 文件，整合Spring:
4.4 cxf-servlet.xml 文件的内容如下，jaxws:endpoint 填写要实现的类，address为地址这个要对应下面提到的4.6 里面 spring配置文件client-beans.xml的address地址，要填相对路径：
<?xml version="1.0" encoding="UTF-8"?> <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.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> <jaxws:endpoint id="helloWorld" implementor="com.yao.spring.service.HelloWorldImpl" address="/HelloWorld"/> </beans>
4.5 在根文件夹下创建client-beans.xml 文件，这个为spring的配置文件。本例中创建了一个源文件夹config，并把client-beans.xml 放进去：
4.6 client-beans.xml 文件如下，<property name="address" value="http://localhost:8080/HelloSpringCXF/services/HelloWorld"/>这个为设置部署到Tomcat后WebService的访问地址，最后的/HelloWorld 就是对应 4.4 cxf-servlet.xml 里jaxws:endpoint的address，这个client bean 就可以调用服务器里的HelloWorld接口了：
<?xml version="1.0" encoding="UTF-8"?> <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.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schema/jaxws.xsd"> <bean id="client" class="com.yao.spring.service.HelloWorld" factory-bean="clientFactory" factory-method="create"/> <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="com.yao.spring.service.HelloWorld"/> <property name="address" value="http://localhost:8080/HelloSpringCXF/services/HelloWorld"/> </bean> </beans>
package com.yao.spring.client; import java.util.List; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.yao.spring.service.HelloWorld; public final class Client { private Client() { } public static void main(String args[]) throws Exception { ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(new String[] { "client-beans.xml" }); HelloWorld client = (HelloWorld) context.getBean("client"); String response = client.sayHi("Joe"); System.out.println("Response: " + response); List<String> lists = client.getListString(); if (lists != null && lists.size() > 0) { for (String list : lists) { System.out.println(list); } } context.close(); System.exit(0); } }
七、运行Client 类并打印：
