The best way to initialize a bean in Camel - apache-camel

Question

What would be the best (both human readable and fastest in runtime (say, compiled)) way to initialize a bean in Camel?
I need a bean to send it to JPA endpoint. The input is a Map created out of CSV. Looks like a trivial task, but I have just started with Camel, please help.
Currently I have managed to transform a Map into a more complicate Map that has the same strucure as my beans. I could write my own code that would traverse it, instantiate the lists and the lists members, employing Apache Beanutils, but I think there should be a faster way to initialize a bean right from the original Map, without creating an intermediate Map.
Here is what I currently have:
<route id="AgencyCsvInput" errorHandlerRef="agencyDeadLetters">
<from uri="direct:agencyCsvInput"/>
<split streaming="true">
<method ref="csvSplitter" method="tokenizeReader"/> <!-- prepends the first line of file for every subsequent line -->
<log message="splitted: ${body}" loggingLevel="DEBUG"/>
<setHeader headerName="inputRegistryLines">
<simple>${body}</simple>
</setHeader>
<unmarshal>
<csv delimiter=";" useMaps="true" />
</unmarshal>
<log message="unmarshalled: size: ${body.size()}, ${body}" loggingLevel="DEBUG"/>
<filter>
<simple>${body.size()} == 1</simple><!-- be sure to have spaces around an operator -->
<log message="filtered: listItem: ${body[0]['PATRONYMIC']}, list: ${body}" loggingLevel="DEBUG"/>
<setProperty propertyName="parser">
<simple>ref:patternParser</simple>
</setProperty>
<transform>
<spel><![CDATA[#{

See how easy it is to transform a Map in a legible way, with just a couple of custom dates and number parser functions and SpEL inline Map/List instantiate syntax. It workedlike a charm when I had Hibernate "dynamic maps", so that my persistent objects were really the java.util.Maps. I'd wish to have the same easy way to instantiate a bean. It has some fields of List type, the type of listed objects is known, and they in turn may have other lists as their fields - all of them are based on beans with getters and setters.
Probably, the BeanShell has an inline bean initializing syntax? Or Camel has a way to invoke getters/setters and read the Map?
I want to avoid of scripting like this:
result = new myBean();
result.dateOpen = properties['parser'].date(body[0]['ACTIVATION_DATE'], 'dd.MM.yyyy H:mm');
balances = new Balances();
result.balances = balances;
balance = new List<Balance>();
reallyBalance = new Balance();
balance.add(balance);
reallyBalance.typeCd="loanAmount";
....
I find it ilegible.
It's a pure Camel question, but I'll mark it as Beanshell as well, hoping for hints of inline bean init syntax like:
bean = new MyBean(){dateOpen= properties['parser'].date(body[0]['ACTIVATION_DATE'], 'dd.MM.yyyy H:mm')....};
