工厂模式实现webservice远程调用

1.建立xml报文转换接口；

public interface XmlBeanConverter {

//xml转对象

T fromXml(String xml, Class targetClass, String encoding);

//对象转xml

 StringtoXml(Object xmlObject, String encoding);

}

2.建立公共的抽象类，2个方法，1个方法调用远程调用返回结果，一个方法报文解析返回对象：

public abstract class NbSmWebServiceInvoctionBuildimplements XmlBeanConverter {

@Autowired

  private NbWebServiceInvocationServiceNbWebServiceInvocationService;

  //远程调用返回xml报文

  public StringdoInvoke(String requestXml, String sjblx) {

long timeStart = System.currentTimeMillis();

      String responseXml =NbWebServiceInvocationService.innerInvoke(sjblx, requestXml);

      long timecost = System.currentTimeMillis() - timeStart;

      return responseXml;

  }

//解析xml报文转对象

  @Override

  public T fromXml(String xml, Class targetClass, String encoding) {

JaxbXmlBeanConverter jaxbXmlBeanConverter =new JaxbXmlBeanConverter();

      return jaxbXmlBeanConverter.fromXml(xml, targetClass, "utf-8");

  }

}

3.建立工厂类，工厂类只有一个方法，生产返回对象

public class Factory {

public Objectfactory(NbSmWebServiceInvoctionBuild builder,Object request,String sjblx,Class responseClass){

String toXml = builder.toXml(request, "utf-8");

      String fromXml = builder.doInvoke(toXml, sjblx);

      return builder.fromXml(fromXml,responseClass,"utf-8");

  }

}

4.每次使用只需要新建一个类继承NbSmWebServiceInvoctionBuild抽象类，实现toXml方法，：

public class NbSmWebServiceInvoctionJtBuild extends NbSmWebServiceInvoctionBuild {

@Override

  public StringtoXml(Object xmlObject, String encoding) {

return "xml";

  }

}

5.使用：

public class Test {

public static void main(String[] args) {

Factory factory=new Factory();

      NbSmWebServiceInvoctionBuild jtBuild=new NbSmWebServiceInvoctionJtBuild();

      Object request=new Object();

      Object respsonse = factory.factory(jtBuild, request, "sjlx", null);

      System.out.println(respsonse.toString());

  }

}

总结：封装了内部的调用细节，每次根据不同的请求参数，返回相应的处理结果；
