Getting a JCR Node in .json form from OSGI bundle

I'm trying to get a JCR node as JSON within the context of a Java Class. I was curious if there was an internal API for JCR that will return the Node as a JSON w/ an array of it's child nodes.

A good example would be the output that you would get from making an request to mynode.infinity.json in the browser.

I took at look at JsonJcrNode class, and it does give me what I want, but it excludes the children of the target node.

I'm thinking that I will have to manually get a node and it's children and then iterate through properties and manually create my JSONObject. I was just curious if this has been done already or if there are any other interfaces I'm missing that could help me solve this issue.

thank you,

Brodie

Solution

  • JsonItemWriter class does exactly what you need:

    Node node = session.getNode("/content/geometrixx/en/toolbar/contacts");
StringWriter stringWriter = new StringWriter();
JsonItemWriter jsonWriter = new JsonItemWriter(null);
jsonWriter.dump(node, stringWriter, -1, true);
String json = stringWriter.toString();

    The dump() method allows to specify recursion level (-1 for infinity) and optionally produces nicely formatted output (pass true as the last parameter).
