基于Apache CXF的Web Service服务端/客户端

转自：https://www.aliyun.com/zixun/wenji/1263190.html

CXF服务端：

1. package com.sean.server;
2. import javax.jws.WebParam;
3. import javax.jws.WebService;
4. @WebService
5. public interface Plus {
6. public int add(@WebParam(name="x") int x, @WebParam(name="y") int y);
7. }

1. package com.sean.server;
2. public class PlusImpl implements Plus {
3. public int add(int x, int y){
4. return x + y;
5. }
6. }

1. package com.sean.server;
2. import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
3. import org.apache.cxf.frontend.ServerFactoryBean;
4. public class Server {
5. public static void main(String args[]) throws Exception {
6. PlusImpl plusImpl = new PlusImpl();
7. JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
8. //ServerFactoryBean factory = new ServerFactoryBean();
9. factory.setServiceClass(Plus.class);
10. factory.setAddress("http://127.0.0.1:8888/Plus");
11. factory.setServiceBean(plusImpl);
12. factory.create();
13. }
14. }

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

1. <?xml version="1.0" encoding="UTF-8"?>
2. <wsdl:definitions targetNamespace="http://server.sean.com/"

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

1. package com.sean.client;
2. import org.apache.cxf.frontend.ClientProxyFactoryBean;
3. import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
4. import com.sean.server.Plus;
5. public class Client {
6. public static void main(String[] args) {
7. //ClientProxyFactoryBean factory = new ClientProxyFactoryBean();
8. JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
9. factory.setAddress("http://127.0.0.1:8888/Plus");
10. Plus client = factory.create(Plus.class);
11. System.out.println(client.add(2, 2));
12. System.exit(0);
13. }
14. }

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

1. package com.sean.client;
2. import org.apache.cxf.endpoint.Client;
3. import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
4. public class Client2 {
5. public static void main(String[] args) throws Exception {
6. JaxWsDynamicClientFactory factory = JaxWsDynamicClientFactory.newInstance();
7. Client client = factory.createClient("http://127.0.0.1:8888/Plus?wsdl");
8. Object[] inputs = {1, 2};
9. Object[] result = client.invoke("add", inputs);
10. System.out.println(result[0]);
11. }
12. }
