接上例：http://blog.csdn.net/kunshan_shenbin/archive/2009/01/07/3726803.aspx

这里我们对Spring Web Service技术做一下强化，例子仍然来自他自带的Demo。

如下图所示建立工程：

代码如下：

HolidayClient.java

package com.mycompany.hr.client.sws;

    private Resource request;
    public void setRequest(Resource request) {
        this.request = request;
    }
    public void holiday() throws IOException {
        
        Source requestSource = new ResourceSource(request);
        getWebServiceTemplate().sendSourceAndReceiveToResult(requestSource, null);
    }
    public static void main(String[] args) throws IOException {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml", HolidayClient.class);
        HolidayClient holidayClient = (HolidayClient) applicationContext.getBean("holidayClient");
        holidayClient.holiday();
    }
}
