在CXF中啓用了MTOM，但無法上傳大文件

Question

我正在使用CXF 2.3.9創建上載Web服務。這裏是我的服務器bean的一小部分

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

我cxf.xml

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

當wsdl2java.bat的生成文件時，我看到我的DataHandle類型轉換爲byte []。我將它們改回到DataHandle並導入必要的庫。

當我跑我的客戶，我得到了下面的堆棧跟蹤

我怎樣才能解決呢？謝謝你和問候

Answer 1

這是有效的，如果你是以下this tutorial

您需要刪除下面幾行：

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

下面的代碼添加到客戶端

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(); 

如果您使用的是Eclipse，請嘗試將jaxb-api.jar和jaxws-api放入您的jre庫之上的classpath中，否則認可對我無效。
