CSVThe CSV Data Format uses Apache Commons CSV Marshalling a Map to CSVThe component allows you to marshal a Java Map (or any other message type that can be converted in a Map) into a CSV payload. An example: if you send a message with this map... Map body = new HashMap(); body.put("foo", "abc"); body.put("bar", 123); ... through this route ... from("direct:start"). marshal().csv(). to("mock:result"); ... you will end up with a String containing this CSV message abc,123 Sending the Map below through this route will result in a CSV message that looks like foo,bar Unmarshalling a CSV message into a Java ListUnmarshalling will transform a CSV messsage into a Java List with CSV file lines (containing another List with all the field values). An example: we have a CSV file with names of persons, their IQ and their current activity. Jack Dalton, 115, mad at Averell
Joe Dalton, 105, calming Joe
William Dalton, 105, keeping Joe from killing Averell
Averell Dalton, 80, playing with Rantanplan
Lucky Luke, 120, capturing the Daltons
We can now use the CSV component to unmarshal this file: from("file:src/test/resources/daltons.csv?noop=true"). unmarshal().csv(). to("mock:daltons"); The resulting message will contain a List<List<String>> like... List<List<String>> data = (List<List<String>>) exchange.getIn().getBody(); for (List<String> line : data) { LOG.debug(String.format("%s has an IQ of %s and is currently %s", line.get(0), line.get(1), line.get(2))); } |
