jpa


how to pass namedQuery parameters in Apache Camel JPA by header?


I have this camel route:
from("direct:getUser")
.pollEnrich("jpa://User?namedQuery=User.findById&consumeDelete=false");
This is my user Entity:
#Entity
#NamedQueries({
#NamedQuery(name="User.findAll", query="SELECT u FROM User u"),
#NamedQuery(name="User.findById", query="SELECT u FROM User u WHERE u.id = :id")
})
public class User{
#Id
private String id;
}
I have tried this route by setting the header:
from("direct:getUser")
.setHeader("id", simple("myid"))
.pollEnrich("jpa://User?namedQuery=User.findById&consumeDelete=false");
But it is not working
Is there any method to set jpa properties by the headers? The camel documentation quote this in parameters option but i don't found the examples
Options: parameters
This option is Registry based which requires the # notation. This
key/value mapping is used for building the query parameters. It is
expected to be of the generic type java.util.Map where
the keys are the named parameters of a given JPA query and the values
are their corresponding effective values you want to select for. Camel
2.19: it can be used for producer as well. When it's used for producer, Simple expression can be used as a parameter value. It
allows you to retrieve parameter values from the message body header
and etc.
