Hi Michael, Since Sling itself is a framework for building web applications with it’s own persistence and services layer it’s a bit unusual to get questions on integration with Spring here (I think). But I don’t know enough about your application and its use cases to question why you are doing this. ButI think you you can use JCR API to persist your DTOs. Look up JCR API and Apache Jackrabbit and OAK projects.
Technically you could do away with Sling entirelly and use Apache Jackrabbit or OAK directly if all you are using Sling for is as document/content store. But again don’t know enough about your application. And I don’t really want to discourage you from using Sling since I am a big fan. :) Henry > On Jul 22, 2015, at 1:36 PM, Haefele, Michael <[email protected]> > wrote: > > We have a Sling application that we're using basically as a database/file > manager for portions of a java Spring application. > > In java we have a bunch of DTOs that we import by converting to json using > Jackson and persisting to Sling using the import option on the Sling post > servlet. > We then read them using .tidy.infinity.json and convert back to DTOs using > Jackson again. > This is working really well. > > But we've reached point where we need to modify some of the data in Sling and > it seems like I've hit a bit of a conceptual wall. > I was thinking we'd keep the DTO pattern going. > Load the DTO, modify some value, push the updated DTO back to Sling. > > But it seems the POST servlet doesn't support json when doing a modify > operation. > I basically took that as a hint that I might be barking up the wrong tree > here. > > We could also do the updates by posting specific properties, but it seems > like that's opening the door to writing a lot of custom update code. > > > Does anyone have any suggestions for best practices for this sort of thing? > Am I trying too hard to apply RDBMS/hibernate style patterns? > > > Thanks for taking to the time to read a somewhat open ended question.
