How to COMBINE 4 JSON objects/files to create ONE JSON file - json

Question

OK, this is probably a REAL simple request.
But, I have 4 JSON files, well, I get JSON when doing a GET to a
//some IP address/some directory/some sub directory/name of folder
So I get back let's just say, NETWORKS, SITES, RESOURCES, COMPONENTS
Each one below NETWORKS is the CHILD...
Ok, next: I need to COMBINE these JSON files to populate JSTree (from jstree.com)
I have a basic JSON file like this and it WORKS beautifully:
(NOTE: the ID's below are irrelevant and DO NOT match in the REAL examples farther down here.)
The intent here is to JOIN all four JSON objects which I'm getting through a RESTful environment to JAVA API's that GET the data from the database.
[
{
"data": "Network 1",
"metadata": {"id" : "n1"},
"children": [ {
"data": "Site 1",
"metadata": {"id" : "s1"},
"children": [ {
"data": "Resource 1",
"metadata": {"id" : "r1"},
"children": [
{
"data": "Component 1",
"metadata": {"id" : "c1"}
},
{
"data": "Component 2",
"metadata": {"id" : "c2"}
},
{
"data": "Component 3",
"metadata": {"id" : "c3"}
} ] } ] },
"Site 2",
"Site 3",
"Site 4"]
}
]
Here's my dilemma:
I need to combine the following JSON files: SITES, RESOURCES, and COMPONENTS
Simple right? Not so much.
Here's a sample of each of the lower level JSON Objects:
NETWORKS:
[
{
"id": "23ef0d23-0d8d-4466-98da-81ef30791773",
"notes": "This is a network for network 1",
"name": "n1"
},
{
"id": "b4b46748-511a-49bf-9d22-8da014c76cc2",
"notes": "This is a network for network 2",
"name": "n2"
},
{
"id": "678b4a01-a6a6-449f-966d-c50c74964729",
"notes": "This is a network for network 3",
"name": "n3"
},
{
"id": "8e2822b1-49a8-498e-979b-2849cfa82148",
"notes": "This is a network for network 4",
"name": "n4"
}
]
SITES:
[
{
"id": "05683e7b-e471-4417-bead-317cfcbfaf30",
"name": "s1",
"networkId": "23ef0d23-0d8d-4466-98da-81ef30791773",
"notes": "This is site 1"
},
{
"id": "de8d654c-f9c4-4a4e-8742-32794b218b54",
"name": "s2",
"networkId": "23ef0d23-0d8d-4466-98da-81ef30791773",
"notes": "This is site 2"
},
{
"id": "16b2b1cf-2991-4717-ae65-2158700fa95d",
"name": "s3",
"networkId": "8e2822b1-49a8-498e-979b-2849cfa82148",
"notes": "This is site 3"
}
]
RESOURCES:
[
{
"id": "26db6a18-5099-4117-9adb-b8c808a3c478",
"networkId": "23ef0d23-0d8d-4466-98da-81ef30791773",
"siteId": "05683e7b-e471-4417-bead-317cfcbfaf30",
"name": "r1",
"notes": "This is Resource 1"
},
{
"id": "26ad2b53-f4b2-41c1-a618-d9e710452b7f",
"networkId": "23ef0d23-0d8d-4466-98da-81ef30791773",
"siteId": "05683e7b-e471-4417-bead-317cfcbfaf30",
"name": "r2",
"notes": "This is Resource 2"
}
]
And Finally, COMPONENTS:
[
{
"id": "6e8d13ad-9eb6-4213-bf84-a6e91d2e1460",
"resourceId": "26ad2b53-f4b2-41c1-a618-d9e710452b7f",
"siteId": "05683e7b-e471-4417-bead-317cfcbfaf30",
"networkId": "23ef0d23-0d8d-4466-98da-81ef30791773",
"name": "Component 1",
"notes": "This is my very first component - Yay!"
},
{
"id": "8f18cca3-378e-4f9b-8a39-eb2285fa61fd",
"resourceId": "26ad2b53-f4b2-41c1-a618-d9e710452b7f",
"siteId": "05683e7b-e471-4417-bead-317cfcbfaf30",
"networkId": "23ef0d23-0d8d-4466-98da-81ef30791773",
"name": "Component 2",
"notes": "This is my Second component - Yay!"
},
{
"id": "539370a6-577f-477d-a6ea-d45efd7e65aa",
"resourceId": "26ad2b53-f4b2-41c1-a618-d9e710452b7f",
"siteId": "05683e7b-e471-4417-bead-317cfcbfaf30",
"networkId": "23ef0d23-0d8d-4466-98da-81ef30791773",
"name": "Component 3",
"notes": "This is my Third component - Yay!"
}
]
Ultimately, when combined, it's GOT to look like the very first JSON example which WORKS for JSTree.
Thank you all for helping.
