WebService的实现——cxf

一、所需的jar包(http://download.csdn.net/detail/huangzebiao007/6380241)

二、实例

1、创建对外发布的接口和实现类

package com.hzb;
import javax.jws.WebService;
@WebService
public interface HelloWorld {
	public String sayHello(String name);
}

package com.hzb;
import javax.jws.WebService;
public class HelloWorldImpl implements HelloWorld {
	public String sayHello(String name) {
		return name+":hello world!";
	}
}

package com.hzb;
import javax.xml.ws.Endpoint;
public class WebServiceApp {
?? ?? public static void main(String[] args) {
????????? System.out.println("web service starting");
????????? HelloWorldImpl implementor= new HelloWorldImpl();
????????? String address="http://localhost:8080/helloWorld";
????????? Endpoint.publish(address,implementor);
????????? System.out.println("web service started");
?? ?? }
}

package com.hzb;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
public class HelloWorldClient {
	public static void main(String[] args) {
          JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean();
          svr.setServiceClass(HelloWorld.class);
          svr.setAddress("http://localhost:8080/helloWorld");
          HelloWorld hw = (HelloWorld) svr.create();
          System.out.println(hw.sayHello("hzb"));
	}
}

先启动发布类，然后在启动客户端，输出：hzb:hello world!

三、Spring集成cxf

1、创建一个WebServiceCXF项目用于发布webservice，引入上面的jar包

（1）创建接口
package com.cxf;
import javax.jws.WebService;
@WebService 
public interface HelloWorld {
	public String sayHello(String name);
}
（2）创建接口实现类
package com.cxf;
import javax.jws.WebService;
public class HelloWorldImpl implements HelloWorld {
?? ?public String sayHello(String name) {
?? ??? ?return name+":hello world!";
?? ?}
}
（3）配置applicationContext.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" />
?? ?
?? ?<!-- implementorClass指向该接口的实现类，
?? ?address指定该接口暴露的地址（前面是http://ip:port/project/web.xml中配置的访问前缀） -->
?? ?<jaxws:endpoint id="helloWorld"
?? ??? ?implementorClass="com.cxf.HelloWorldImpl"
?? ??? ?address="/HelloWorld" />
?? ??? ?
</beans>
（4）在web.xml文件中配置cxf和spring
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
?? ?xmlns="http://java.sun.com/xml/ns/javaee" 
?? ?xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
?? ?xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
?? ?http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
? <welcome-file-list>
?? ?<welcome-file>index.jsp</welcome-file>
? </welcome-file-list>
?? ?<context-param>
?? ??? ?<param-name>contextConfigLocation</param-name>
?? ??? ?<param-value> classpath:/applicationContext.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>
?? ??? ?<load-on-startup>2</load-on-startup>
?? ?</servlet>
?? ?<servlet-mapping>
?? ??? ?<servlet-name>CXFServlet</servlet-name>
?? ??? ?<url-pattern>/webservice/*</url-pattern>
?? ?</servlet-mapping>? ?
</web-app>

项目部署到web服务器后，就可以通过http://localhost:8080/WebServiceCXF/webservice访问到发布的所有接口了

（1）配置applicationContext.xml文件
<?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"> 
    ?<!-- serviceClass是所要访问的webService接口,而address是要访问的接口地址 -->
	<jaxws:client id="helloClient" serviceClass="com.cxf.HelloWorld"  
        address="http://localhost:8080/WebServiceCXF/webservice/HelloWorld" />  
        
</beans>

（2）创建client访问类
package com.hzb;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.cxf.HelloWorld;

public class Client {
?? ?public static void main(String[] args) { ???? ? ?
??????? ApplicationContext context = new ClassPathXmlApplicationContext( ?
??????????????? "applicationContext.xml"); ?
??????? HelloWorld client = (HelloWorld) context.getBean("helloClient"); ?
??????? String message = client.sayHello("hzb"); ?
??????? System.out.println(message); ?
??? } ?
}
运行该类，得到结果：hzb:hello world!

注意：上面是假设webservice发布是能拿到整个项目，所以客户端访问才能直接导入该包，如果不是的话，那就要通过访问wsdl文件，然后根据该文件得到接口。
