I'm a new RESTlet user and I was wondering if it's possible to route
dynamically based on templates retrieved from a database in order to allow new
templates to be added without changing any code? My plan is to have a table of
URL templates together with their mappings, per request type, to stored
procedure calls. The resource would then construct the stored procedure call
based on which template was matched and map the parameters in the template to
the procedure parameters.
For example:
URL Request Stored Procedure
/customers GET CustomersGet()
POST CustomerCreate(name...)
/customers/{cus} GET CustomersGetById(cus)
/invoices GET InvoicesGet()
/invoices/{inv} GET InvoicesGetById(inv)
I wanted to have a single resource class that would be called for all templates
that could, based on the template that matched and the request, look-up the
stored procedure and construct the call to it dynamically by taking the
parameters extracted by the framework and any supplied in the request body and
matching them to the stored procedure parameters. Unfortunately I couldn't find
a way to get the template that was matched.
The background behind this is that I am trying to create a system whereby new
web applications can be developed without changing any Java code, simply by
implementing the relevant stored procedures in the database and changing the
configuration (it's not a problem if a server restart is required). All
resources, such as HTML pages, JPEGs, Freemarker templates etc. are stored in
the backend database as BLOBs are are served from there so that they can be
easily modified and new ones uploaded.
Thanks in advance,
Tim.
