Camel - Using property in Spring DSL

I'm trying to set some properties in my process method but I'm not able to figure out that how to use those properties in xml, like I can use header values in xml easily by using syntax : ${in.header.myKey}

Here's my code :

    <route>
        <from uri="activemq:queue:start.queue" />
            <to uri="stream:out" />
            <process ref="jsonProcessor"></process>
             <to uri="bean:validateInputIdentifiers?method=validation(${in.property.SourceMap}, ${in.property.DestinationMap})" />
    </route>

Here in.property.SourceMap is Unknown function. What is the correct way? Would be great if it is something similar to header. Also I want to use property only and not header since values of header may not persists later in my routes.

Here's process method code:

@Override
public void process(Exchange exchange) throws Exception {
    List<Map<String, String>> body = exchange.getIn().getBody(List.class);
    Map<String, String> sourceMap = body.get(0);
    Map<String, String> destinationMap = body.get(1);
    exchange.setProperty("SourceMap", sourceMap);
    exchange.setProperty("DestinationMap", destinationMap);

}

Kindly provide the solution.

There could be multiple solution combinations for your problem.

Sample Property Key and Value.

<cm:property name="app.user" value="PROD008"/>

In Route if u want to set header with property value. Use below code snippet.

<setHeader headerName="password">
    <simple>${properties:app.user}</simple>
</setHeader>

If you want to use property, you can use below snippet.

<to uri="{{some.endpoint}}"/>

For your example: if Properties are SourceMap and DestinationMap you can use any of below.

1. <to uri="bean:validateInputIdentifiers?method=validation(${property.SourceMap}, ${property.DestinationMap})" />

2. <to uri="bean:validateInputIdentifiers?method=validation({{SourceMap}},{{DestinationMap}})" />

If you want to use header instead of property then use below code snippet.

<to uri="bean:validateInputIdentifiers?method=validation(${header.SourceMap}, ${header.DestinationMap})" />

After hit and trial I got the working solution:

<route>
        <from uri="activemq:queue:start.queue" />
            <to uri="stream:out" />
            <process ref="jsonProcessor"></process>
             <to uri="bean:validateInputIdentifiers?method=validation(${property.SourceMap}, ${property.DestinationMap})" />
    </route>
