使用CXF编写WebService

CXF下载地址：http://cxf.apache.org/download.html

解压后可以看到lib、bin、docs等目录。在lib有我们需要的jar包。

在eclipse中创建一个java项目，并引入lib下面的包

创建创建一个接口ICaculateService

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

@WebService
public interface ICaculateService {
public String getName(@WebParam(name="name")String name);
}

在创建CaculateService类来实现ICaculateService接口

import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

@WebService
@SOAPBinding(style=Style.RPC)
public class CaculateService implements ICaculateService {
public String getName(@WebParam(name="name")String name) {
return "chenbin";
}
}

接下来部署WebService

public class DeployWebService {
public static void deployService() {
System.out.println("server start ...");
ICaculateService service = new CaculateService();
String addresString = "http://localhost:9000/caculate";
Endpoint.publish(addresString, service);
}

public static void main(String[] args) throws InterruptedException {
deployService();
System.out.println("server ready ...");
Thread.sleep(1000*60);
System.out.println("server exiting");
System.exit(0);
}
}

WebService发布好之后，就创建一个客户端来调用这个服务。在同一个项目中，创建Client类

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

public class Client {
public static void main(String[] args) {
JaxWsProxyFactoryBean factory1 = new JaxWsProxyFactoryBean();
factory1.setServiceClass(ICaculateService.class);
factory1.setAddress("http://localhost:9000/caculate");
ICaculateService service = (ICaculateService) factory1.create();
System.out.println(service.getName(""));
}
}

我们也可以新建一个项目来调用刚刚发布的WebService。需要把ICaculateService重写一遍，并且命名空间也要相同。代码和Client类是一样的。
