To access a property value from the properties component, invoke the resolve
method on the built-in properties
attribute, as follows:
.setHeader("myHeader").ruby("properties.resolve(PropKey)")
.setHeader("myHeader").ruby("properties.resolve(PropKey)")
Where PropKey is the key of the property you want to resolve, where the key value is of String
type.
For more details about the properties component, see Properties in the Apache Camel Component Reference Guide.
