Camel route to filter out the auto response emails

阅读更多关于 Camel route to filter out the auto response emails

I am using camel rout to consume the emails from my inbox folder. But I want to filter out the auto responded emails like out of offices etc. I see there is a option for to process only unread messages by using option unseen=true . The URI that I am using to consume the emails looks like: pop3://username@host?password=password;delete=true&unseen=true&consumer.delay=60000 I think what you're looking for is the searchTerm property to add to your endpoint URI. If you want to filter out e-mails with the term Out Of Office in them, your endpoint URI might look like this: pop3://username@host.com

Alternative to deprecated XmlJsonDataFormat in Apache Camel

阅读更多关于 Alternative to deprecated XmlJsonDataFormat in Apache Camel

问题 In Apache Camel, I was trying to use XmlJsonDataFormat to do a quick conversion from XML to JSON. However the XMLJSON (http://camel.apache.org/xmljson.html) has deprecated so I am not sure what is the best way to do that conversion aside from creating a processor. Does anyone know of an alternative to XmlJsonDataFormat? 回答1: After some tries, I have managed to get what I need by combining Jaxb and Jackson for unmarshal XML to POJO and then POJO to JSON. As noMad pointed out, I could have

阅读更多关于 Apache Camel/ActiveMQ priority route

问题 I have two AMQ queues that have the same consumers. The first queue (Q1) handles 97% of the messages and the other (Q2) only 3%. Problem is that messages in Q2 need to process messages as soon as they are queued. So my problem is that when a message is available in Q2 I need somehow to suspend the first route to take it's consumers. The apache camel routing looks like this: <route id="q1"> <from uri="jms:recordAnalysisRequests" /> <to uri="bean:analysisService" /> </route> <route id="q2">
