cxf + spring 集成开发webservice

1. 用cxf + spring 开发webservice

/**
 * @author liuqing
 * 
 */
package demo.hw.server;

import javax.jws.WebService;


/**
 * webservice 接口
 * @author liuqing
 *
 */
@WebService
public interface HelloWorld {
    
    String sayHello(String text);
}

2. cxf 接口实现类

 

package demo.hw.server;


/**
 * 
 * @author liuqing
 * webservice 实现类
 */
public class HelloWorldImpl implements HelloWorld {

    public String sayHello(String text) {
        System.out.println("sayHi called");
        return "Hello " + text;
    }
}

  3. 配置web.xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>cxfspring</display-name>
  <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>WEB-INF/beans.xml</param-value>
    </context-param>
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
     <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>/services/*</url-pattern>
     </servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

 

4. spring beans.xml

<?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">

	<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" />

	<jaxws:endpoint 
	  id="helloWorld" 
	  implementor="demo.hw.server.HelloWorldImpl" 
	  address="/HelloWorld" />
	
</beans>
<!-- END SNIPPET: beans -->

5. 启动tomcat

2011-6-2 17:06:31 org.apache.cxf.transport.servlet.CXFServlet updateContext
信息: Load the bus with application context
2011-6-2 17:06:31 org.springframework.context.support.AbstractApplicationContext prepareRefresh
信息: Refreshing org.apache.cxf.bus.spring.BusApplicationContext@1971eb3: startup date [Thu Jun 02 17:06:31 CST 2011]; parent: Root WebApplicationContext

6. 生成wsdl 文件

  <?xml version="1.0" encoding="UTF-8" ?> 
- <wsdl:definitions name="HelloWorldImplService" targetNamespace="http://server.hw.demo/" xmlns:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://server.hw.demo/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
