Property Expression Language
The Property Expression Language allows you to extract values of named exchange properties.
Example usage
The recipientList element of the Spring DSL can utilize a property expression like:
Error formatting macro: snippet: java.lang.NullPointerException
In this case, the list of recipients are contained in the property 'myProperty'.
And the same example in Java DSL:
Error formatting macro: snippet: java.lang.NullPointerException
And with a slightly different syntax where you use the builder to the fullest (i.e. avoid using parameters but using stacked operations, notice that property is not a parameter but a stacked method call)
from("direct:a").recipientList().property("myProperty");
Dependencies
The Property language is part of camel-core.
