高手救急!!服务器未能识别 HTTP 头 SOAPAction 的值: 。

  刚开始接触 spring webservice 听说是contact-first  想尝尝鲜 不料出错了. 以下是我的代码 
public class WebServiceClient extends WebServiceGatewaySupport {
    
   //private static String soapActionPrefix = "http://tempuri.org/";
    private Resource request;    public void setRequest(Resource request) {
        this.request = request;
    }
 
public void getWeather()throws IOException{
       //replaceCityName(city);
       Source requestSource = new ResourceSource(request);
       StringResult result = new StringResult();
       System.out.println(requestSource);
       System.out.println(getWebServiceTemplate().getDefaultUri());
       getWebServiceTemplate().sendSourceAndReceiveToResult(requestSource, result);
       System.out.println(result);
   }
    public static void main(String[] args){
       // new WebServiceClient().newMethod("成都");
        ApplicationContext applicationContext =
            new ClassPathXmlApplicationContext("applicationContext.xml", WebServiceClient.class);
        WebServiceClient webServiceClient = (WebServiceClient) applicationContext.getBean("webServiceClient");
    try {
        webServiceClient.getWeather();
    } catch (IOException ex) {
        ex.printStackTrace();
    }
    }
这个是applicationContext.xml 代码
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <bean id="webServiceClient"
class="com.mathew.gwt.springws.WebServiceClient">
<property name="request" value="classpath:com/mathew/gwt/springws/weather.xml"/>
<property name="defaultUri" value="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx" />
</bean>
</beans>
 
以下是XML代码<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<getWeatherbyCityName xmlns="http://WebXml.com.cn/">
<theCityName>成都</theCityName>
</getWeatherbyCityName>
</soap:Body>
</soap:Envelope>大家帮帮忙! 谢谢了
