Java 为什么这个春豆没有初始化？它总是空的。

我配置了一个消息工厂bean，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <bean id="soapMessageFactory" class="javax.xml.soap.MessageFactory" factory-method="newInstance" />
    <bean id="saajMessageFactory" class="org.springframework.ws.soap.saaj.SaajSoapMessageFactory">
            <constructor-arg ref="soapMessageFactory" />
    </bean>

    <bean id="myService" class="com.mypackage.TestEndPoint">
        <property name="saajMessageFactory" ref="saajMessageFactory" />
    </bean> 



</beans>

TestEndpoint类如下所示

@Endpoint
public class TestEndPoint {


    ObjectFactory objectFactory = new ObjectFactory();
    SaajSoapMessageFactory saajMessageFactory;


    @PayloadRoot(namespace="http://ws.mypackage.com", localPart="downloadSaajMessageRequest")
    @ResponsePayload
    public JAXBElement<DownloadResponseSaajType> invoke(@RequestPayload DownloadSaajMessageRequest req, MessageContext context ) throws Exception  {

        DownloadResponseSaajType response = new DownloadResponseSaajType();
        //DownloadResponseSaajType.PayLoad payload = new DownloadResponseSaajType.PayLoad();    

        DataHandler handler = new javax.activation.DataHandler(new FileDataSource("c:\\temp\\maven-feather.png"));

            SaajSoapMessage message = saajMessageFactory.createWebServiceMessage();
            message.addAttachment("picture", handler);
            message.addAttachment("picture", handler);

           //payload.setMessagePayLoad(handler);
            //response.setPayLoad(payload);

            response.setRequestName("NAMEOF");
            context.setResponse(message);
            return objectFactory.createDownloadSaajMessageResponse(response); 

    }

    public void setSaajMessageFactory(SaajSoapMessageFactory saajMessageFactory){
        this.saajMessageFactory = saajMessageFactory;
        }

        public SaajSoapMessageFactory getSaajMessageFactory(){
            return saajMessageFactory;
        }
}

@Endpoint
公共类测试点{

}
}

我在尝试让端点工作时遇到了一些问题，当我尝试调试代码时，我发现saajMessageFactory从未初始化，它总是空的。配置有问题吗？

您必须将PayloadRootAnnotationMethodEndpointMappingbean添加到配置xml中

<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"/>

我不是。“myService”只是我给com.mypackage.TestEndPoint类的id，这样我就可以初始化TestEndPoint类中的属性。我这样做不对吗？从ApplicationContext获取MyServicebean，看看saajMessageFactory是否正确初始化。如何初始化？我需要将其添加到配置中吗？我不需要。“myService”只是我给com.mypackage.TestEndPoint类的id，这样我就可以初始化TestEndPoint类中的属性。我这样做不对吗？从ApplicationContext获取MyServicebean，看看saajMessageFactory是否正确初始化。如何初始化？是否需要将其添加到配置中？
