Question

在我的soap mtom优化示例中，我已经实现了Tomcat 7上的一个项目，地铁（玻璃鱼）我已经获得了：

XSD

<xs:element name="retrievePicture" type="tns:retrievePicture"/>
<xs:complexType name="retrievePicture">
  <xs:sequence>
    <xs:element name="inImageNumber" type="xs:int"/>
  </xs:sequence>
</xs:complexType>

<xs:element name="retrievePictureResponse" type="tns:JPEGPictureType"/>
<xs:simpleType name="JPEGPictureType"
    xmime:expectedContentTypes="image/jpeg">
    <xs:restriction base="xs:base64Binary" />
</xs:simpleType>

WSDL

        </operation>
    </binding>
    <service name="PictureManagerService">
        ...
    </service>
</definitions>

SEI

@WebService(wsdlLocation="WEB-INF/wsdl/PictureManagerService.wsdl")
@MTOM
public class PictureManager {
    ....
    @WebMethod(operationName = "retrievePicture")
    public Image retrievePicture(
            @WebParam(name = "inImageNumber") final int inImageNumber) {
        java.awt.Image theImage = null;
        //logic for return Image according request
        return theImage;
    }
}

我的项目包括根据要求下载JPEG图像。在Soapui，我得到以下原始回复：

问题是内容类型＆＃34; image / png＆＃34;是错误的，因为我预期＆＃34; image / jpeg＆＃34;

Answer 1

由于我遇到了类似的问题，我不认为此代码段会生成DataHandler：

<xs:simpleType name="JPEGPictureType"
    xmime:expectedContentTypes="image/jpeg">
    <xs:restriction base="xs:base64Binary" />
</xs:simpleType>

我仍在努力找出原因，但与此同时你也可以像我一样，我认为这对你也有帮助。只需直接使用元素retrievePictureResponse而不是使用xs:simpleType，即可使用此代码：

<xs:element name="retrievePictureResponse" type="xs:base64Binary" 
    xmime:expectedContentTypes="image/jpeg" />

mtom返回总是附件witi content-type =＆＃34; image / png＆＃34;
