基于Apache CXF的Web Service服务端/客户端

CXF服务端：

package com.sean.server;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface Plus {
	public int add(@WebParam(name="x") int x, @WebParam(name="y") int y);
}

package com.sean.server;

public class PlusImpl implements Plus {
	public int add(int x, int y){
		return x + y;
	}
}

package com.sean.server;

import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
import org.apache.cxf.frontend.ServerFactoryBean;

public class Server {
    public static void main(String args[]) throws Exception {
    	PlusImpl plusImpl = new PlusImpl();
    	
        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
    	//ServerFactoryBean factory = new ServerFactoryBean();
        factory.setServiceClass(Plus.class);
        factory.setAddress("http://127.0.0.1:8888/Plus");
        factory.setServiceBean(plusImpl);
        factory.create();
    }
}

程序启动后，访问http://127.0.0.1:8888/Plus?wsdl即可查看自动生成的WSDL文件

	</wsdl:service> 
</wsdl:definitions>

如果服务端使用ServerFactoryBean类，则最终生成的WSDL文件略有不同
 

CXF客户端：

如果服务端使用ServerFactoryBean类，则客户端需要使用JaxWsServerFactoryBean类

如果服务端使用JaxWsServerFactoryBean类，则客户端需要使用JaxWsProxyFactoryBean类

package com.sean.client;

import org.apache.cxf.frontend.ClientProxyFactoryBean;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

import com.sean.server.Plus;

public class Client {
	public static void main(String[] args) {
		//ClientProxyFactoryBean factory = new ClientProxyFactoryBean();
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setAddress("http://127.0.0.1:8888/Plus");
        Plus client = factory.create(Plus.class);
        System.out.println(client.add(2, 2));
        System.exit(0);
	}
}

无论服务端使用ServerFactoryBean类还是JaxWsServerFactoryBean类，都可在客户端使用JaxWsDynamicClientFactory类，并通过反射的方式调用WebService服务端

package com.sean.client;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

public class Client2 {
	public static void main(String[] args) throws Exception {
        JaxWsDynamicClientFactory factory = JaxWsDynamicClientFactory.newInstance();
        Client client = factory.createClient("http://127.0.0.1:8888/Plus?wsdl");
        Object[] inputs = {1, 2};
        Object[] result = client.invoke("add", inputs);
        System.out.println(result[0]);
	}
}
