Camel-csv with List<Map> has arbitrary column order
---------------------------------------------------
Key: CAMEL-4350
URL: https://issues.apache.org/jira/browse/CAMEL-4350
Project: Camel
Issue Type: Improvement
Affects Versions: 2.7.1
Environment: java 1.6
Reporter: Julian Cable
The following route works but the order of the columns is dependent on the
natural ordering of the hashmap. Target systems will have an expectation of the
order of the data.
<route>
<from uri="jetty:http://0.0.0.0:16081/css/mes"/>
<setBody>
<constant>SELECT id, value1, value2 FROM mytable</constant>
</setBody>
<to uri="jdbc:mydb"/>
<marshal>
<csv/>
</marshal>
</route>
Either there needs to be a property for csv that allows hash key ordering to be
specified, or an option to sort the keys, e.g.
<route>
<from uri="jetty:http://0.0.0.0:16081/css/mes"/>
<setBody>
<constant>SELECT id as col1, value1 as col2, value2 as col3 FROM
mytable</constant>
</setBody>
<to uri="jdbc:mydb"/>
<marshal>
<csv sortFields="true" />
</marshal>
</route>
