CXF是支持对附件上传的协议MTOM。
MTOM（SOAP Message Transmission Optimization Mechanism）SOAP 消息传输优化机制，可以在SOAP 消息中发送二进制数据，与SAAJ 传输附件不同，MTOM需要XOP（XML-binary Optimized Packing）来传输二进制数据。MTOM 允许将消息中包含的大型数据元素外部化，并将其作为无任何特殊编码的二进制数据随消息一起传送。MTOM 消息会打包为多部分相关 MIME 序列，放在SOAP 消息中一起传送。因此你可以看出MTOM 并不是将附件转为Base64 编码，这样可以大大的提高性能，因为二进制文件转Base64 编码会非常庞大。
MTOM 方式中要传输的附件必须使用javax.activation.DataHandler 类，然后对象类型还要使用@javax.xml.binding.annotation.XmlMimeType 进行注解，标注这是一个附件类型的数据。
这里拿上传及下载用户的图像为例子，大致的说下CXF的MTOM协议对附件的支持
