我正在向外部SOAP服务发送一条消息,该服务应该使用包含图像等功能的soap消息进行回复。这是我编写的用于发送消息的代码:
@Bean
Jaxb2Marshaller jaxb2Marshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPath("myContextPath");
return jaxb2Marshaller;
}
@Bean
public WebServiceTemplate webServiceTemplate() {
WebServiceTemplate webServiceTemplate = new WebServiceTemplate();
webServiceTemplate.setMessageSender(webServiceMessageSender());
webServiceTemplate.setMarshaller(jaxb2Marshaller());
webServiceTemplate.setUnmarshaller(jaxb2Marshaller());
webServiceTemplate.setDefaultUri(defaultUri);
return webServiceTemplate;
}
public ProcessDocumentResponse sendRequest(MyRequest myRequest) {
MyResponse response = (MyResponse) webServiceTemplate.marshalSendAndReceive(
myRequest,
message -> ((SoapMessage) message).setSoapAction(theAction));
return response;
}
这是从日志中获得的响应:

如您所见,有两个多部分内容。在第一个多部分内容中,ImageData包含:
<OutputImages><ImageData><xop:Include href="cid:http://tempuri.org/1/636433219150087850" xmlns:xop="http://www.w3.org/2004/08/xop/include"/></ImageData><Metadata i:nil="true"/></OutputImages>
链接cid:http://tempuri.org/1/636433219150087850是第二个多部分内容的ID。
问题是在解组消息之后,我的响应包含一个byte [] imageData,它是空的,但应该包含第二个多部分内容中的字节。所以我不知道如何面对这个问题,我应该将一些配置更改为unmarshaller吗? (怎么样?)我应该访问HttpResponse(如何?),但是如何填充响应中的byte []值?
经过一番挣扎,我找到了解决方案。关键是要了解这个机制是如何调用的,我忽略了它,对我感到羞耻。
它被称为MTOM,我的问题的解决方案只是在marshaller创建中的一行:
@Bean
Jaxb2Marshaller jaxb2Marshaller() {
Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
jaxb2Marshaller.setContextPath("myContextPath");
jaxb2Marshaller.setMtomEnabled(true); //that's it!!
return jaxb2Marshaller;
}
当我碰到this帖子,然后寻找MTOM的含义,最后在Spring WS Documentation解决方案时,我找到了解决方案
