如何使用Apache Camel获取已有Exchange对象的邮件附件信息?
答案 0 :(得分:4)
如果您有maven项目,则可以使用此依赖项:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-mail</artifactId>
<version>x.y.z</version>
</dependency>
然后如果您已有Exchange对象,可以尝试:
Message message = exchange.getIn();
if (message.getAttachments().size() > 0) {
for (Map.Entry<String, DataHandler> entry : messageCopy.getAttachments().entrySet()) {
DataHandler dataHandler = entry.getValue();
//get the document filename
String attchmentFilename = dataHandler.getName();
String decodedFilename = MimeUtility.decodeText(attchmentFilename);
//get inputstream of attachment file
InputStream is = dataHandler.getInputStream();
//generic function for extracting attachment content
extractor(is);
}
}
我建议在提取器功能中使用Apache Tika来获取附件内容和其他信息
