Java Metro Framework - MTOM 返回始终附件 Witi 内容类型 = "image/png"

Question

在我的soap客户机优化示例中，我已经实现了Tomcat 7 metro (glassfish)上的一个项目，其中我得到了:

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>

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;
    }
}

我的项目包括下载JPEG图像根据要求。在Soapui中，我得到以下原始响应:

问题是内容类型"image/png"是错误的，因为我期望"image/jpeg"

Answer 1

因为我刚刚遇到了类似的问题，所以我认为这个代码片段不会生成DataHandler:

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

我还在试图找出原因，但同时你可以像我一样做，我想这也会对你有帮助。只需直接使用元素retrievePictureResponse而不是使用xs:simpleType，因此您可以使用以下代码:

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