資源簡介
CXF是支持對附件上傳的協議MTOM。
MTOM（SOAP Message Transmission Optimization Mechanism）SOAP 消息傳輸優化機制，可以在SOAP 消息中發送二進制數據，與SAAJ 傳輸附件不同，MTOM需要XOP（XML-binary Optimized Packing）來傳輸二進制數據。MTOM 允許將消息中包含的大型數據元素外部化，并將其作為無任何特殊編碼的二進制數據隨消息一起傳送。MTOM 消息會打包為多部分相關 MIME 序列，放在SOAP 消息中一起傳送。因此你可以看出MTOM 并不是將附件轉為Base64 編碼，這樣可以大大的提高性能，因為二進制文件轉Base64 編碼會非常龐大。
MTOM 方式中要傳輸的附件必須使用javax.activation.DataHandler 類，然后對象類型還要使用@javax.xml.binding.annotation.XmlMimeType 進行注解，標注這是一個附件類型的數據。
這里拿上傳及下載用戶的圖像為例子，大致的說下CXF的MTOM協議對附件的支持
