动态调用WEBSERVICE,可以通过制定接口来调用

package com.dmwsinvoke;

import java.lang.reflect.Method;

import net.sf.cglib.proxy.Enhancer;
import net.sf.cglib.proxy.MethodInterceptor;
import net.sf.cglib.proxy.MethodProxy;

public abstract class WebServiceProxyFactory
{
	private static Enhancer enhancer = new Enhancer();
	private static String wsdld;
	
	private static void initial(String wsdl, Class clazz)
	{
		enhancer.setSuperclass(clazz);
		enhancer.setCallback(new MethodInterceptorImpl());
		wsdld = wsdl;
	}
	
	public static Object getInstance(String wsdl, Class clazz)
	{
		initial(wsdl, clazz);
		return enhancer.create();
	}
	
	private static class MethodInterceptorImpl implements MethodInterceptor
	{
		public Object intercept(Object obj, Method method, Object[] args,
				MethodProxy proxy) throws Throwable
		{
			if(wsdld == null)
			{
				throw new Exception("WSDL为空");
			}
			String methodName = method.getName();
			Class exceptReturnType = method.getReturnType();
			Object o = DynamicWebServiceInvoker.invokeService(wsdld, methodName,
							args, exceptReturnType);
			return o;
		}
	}
