Generate JSON using groovy - json

Question

I am trying to produce the following JSON structure in Groovy but not getting the output I desire.
{
"settings": [
{
"location": "remote",
"stance": "cold"
},
{
"spareParts": {
"id": "123" {
"info": "In stock"
}
}
}
]
}

Answer 1

First of all, the JSON which is in the question at the moment is invalid. :) Second, since Groovy has great support for this, it doesn't need to be ugly. :)
You can go with closures, maps or combined, see this example: https://github.com/jonatan-ivanov/groovy-training/blob/master/examples/050_JsonBuilder.groovy
Here is an example for your (I think) JSON using maps:
builder = new groovy.json.JsonBuilder(
settings: [
[
location: 'remote',
stance: 'cold'
],
[
spareparts: [
id: '123',
info: 'In stock'
]
]
]
)
println builder.toPrettyString()
And here is its output:
{
"settings": [
{
"location": "remote",
"stance": "cold"
},
{
"spareparts": {
"id": "123",
"info": "In stock"
}
}
]
}

I would use a combination of maps and lists for this. Consider the easier case:
import groovy.json.JsonBuilder
def map = [:]
def map1 = [:]
map1['location'] = 'remote'
def list = []
list << ['id' : '123', 'info' : 'In stock']
map1['spareParts'] = list
map['settings'] = [map1]
def jsonBuilder = new JsonBuilder(map)
println jsonBuilder.toPrettyString()
and then the more complex case (this should be refactored):
import groovy.json.JsonBuilder
def map = [:]
def map1 = [:]
map1['location'] = 'remote'
def list1 = []
list1 << ['id' : '123', 'info' : 'In stock']
map1['spareParts'] = list1
map['settings'] = map1
def map2 = [:]
map2['location'] = 'local'
def list2 = []
list2 << ['id' : '505', 'info' : 'none']
map2['spareParts'] = list2
map['settings'] = [map1, map2]
def jsonBuilder = new JsonBuilder(map)
println jsonBuilder.toPrettyString()
