MappingJacksonJsonView.setRenderedAttributes [SPR-6165]

[spring-projects-issues]

Ken Egervari opened SPR-6165 and commented

Hi, the setRenderedAttributes() method is pretty much useless. In practice, we want to filter out elements that belong to the tree that are nested... not the top level elements. A common idiom is to a list of domain objects, and only wanting specific properties on each domain object to be marshalled. As appears that this is impossible right now, which makes this method useless.

I checked the test cases in your rc1 distribution... and they are really simple. the guy that tested it just made 1 map and a simple bean that wasn't nested at all. If that's all he tested, I'm going to assume nested properties won't work.

Can you please make this work as nested properties and fix the test cases?

If we have a list of Object X and X has a, b, c properties, we should just say a map of "a" and "c" and it should work. Currently, it does not, and it is a big problem.

And I hate to say it, but setting up a map of strings is kind of bloated. It would be nice to have a list of comma-separated strings as an input as well to cut down on the lines of code it takes to write this.

Thanks

Also, some logging wouldn't hurt early... so I know what the keys are and what I need to set. As it stands, I have no idea what is supposed to get into the setRenderedAttributes() map for nested elements.

For this need consider using the new JsonView mechanism support (#11815).
