[jira] [Commented] (GROOVY-7780) JSONBuilder/JSONSlurper: Option to Only Include NonNull values

["John Wagenleitner (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-7780?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15605799#comment-15605799 ] 

John Wagenleitner commented on GROOVY-7780:
-------------------------------------------

This will be possible in 2.5 with the new {{JsonGenerator}}.  It doesn't cover the case for {{JsonSlurper}} (mentioned in the summary).  Since the original pointer for this was a Stackoverflow question about {{JsonBuilder}}, I wonder if this can be resolved and a separate ticket opened for the {{JsonSlurper}} is that is something desired/needed?

{code}
import groovy.json.*

def content = [foo:'bar', baz:null]

def generator = new JsonGenerator.Options()
                    .excludeNulls()
                    .build()

assert generator.toJson(content) == '{"foo":"bar"}'
assert new JsonBuilder(content, generator).toString() == '{"foo":"bar"}'
{code}

> Apparently, it's a native feature of Jackson, which makes me think it's probably available in lots of JSON API's. 
> Any chance this feature could get on the roadmap for JSON Builder (and slurper for that matter)?{quote}
