如何写一个webservice 和消费webservice

@WebService(serviceName = "TestWsService",
        targetNamespace = "http://xxxxxx.com/",
        endpointInterface = "xxxxxxx")
public class TestWsServiceImpl implements TestWsService {
    @Override
    @DbLog(code = "test", name = "测试ws接口")
    public String test(String param) {

        System.out.println("入参："+param);
        return  param;
    }
}

 

@WebService(name = "TestWsService",
        targetNamespace = "http:xxxx.com")
public interface TestWsService {
    /**
     * 保存物料信息
     * @return
     */
    @WebMethod
    String test(String param);

}
消费webservice 

// 创建客户端
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient("http://localhost:8080/except/webService/test?wsdl");
// 需要密码的情况需要加上用户名和密码
// client.getOutInterceptors().add(new ClientLoginInterceptor(USER_NAME,
// PASS_WORD));
Object[] objects = new Object[0];
try {
  // invoke("方法名",参数1,参数2,参数3....);
  objects = client.invoke("test", "hahhha");
  return "返回数据:" + objects[0];
} catch (java.lang.Exception e) {
  e.printStackTrace();
  return "异常:" + e.getMessage();
}
