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!";
}
}

2、创建服务发布类

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");
}
}

3、创建客户端

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
[code]<?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

2、创建一个WebServiceClient客户端项目用于访问webservice，引入上面的jar包和引入上面的整个项目

（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。
