在doc, png, csv 我试了，都没有问题
但是xml 就不行了。

nested exception is:
java.io.IOException: "text/xml" DataContentHandler requires String object, was given object of type class [B

------最佳解决方案--------------------------------------------------------
java.io.IOException: "text/xml" DataContentHandler requires String object, was given object of type class [B
粗一看，DataContentHandler接收的处理对象是不是需要一个类型转换的过程，当前是class [B类型，需要的是String型
可能的话，可以看下这个类SMTPTransport.java:566
