Question

我正在使用CXF 2.3.9创建上传Web服务。这是我的服务器bean的一小部分

@XmlType
public class FileUploader
{  
  @XmlMimeType("application/octet-stream")
  private DataHandler Dfile;
}

我的cxf.xml

 <jaxws:endpoint id="uploadfile"
                  implementor="com.ibm.uploadservice.UploadServiceImpl"
                  address="/UploadWS">
                  <jaxws:properties>
      <entry key="mtom-enabled" value="true"/>
    </jaxws:properties>

当wsdl2java.bat生成文件时，我看到我的DataHandle类型被转换为byte []。我将它们更改回DataHandle并导入必要的库。

当我运行我的客户端时，我得到了以下堆栈跟踪

我该如何解决？谢谢你和最好的问候

如果您关注this tutorial

，则此选项有效

您需要删除以下行：

factory.getInInterceptors().add(new LoggingInInterceptor());
factory.getOutInterceptors().add(new LoggingOutInterceptor());

将以下代码添加到客户端

Map<String,Object> props = new HashMap<String, Object>();
props.put("mtom-enabled", Boolean.TRUE);
JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();

factory.setServiceClass(UploadSEI.class);
factory.setAddress("http://localhost:8080/CxfService/UploadWS");
factory.setProperties(props); 

UploadSEI client = (UploadSEI) factory.create();

如果您正在使用Eclipse，请尝试将jaxb-api.jar和jaxws-api放在jre库上方的类路径中，并且认可对我不起作用。
