Convert plist format text to json format

Question

Application uses Apache Cayenne.

I receive a string in the following format. This string is available for me in HashMap format as well.

{And=[(effectiveDate >= Tue Sep 01 00:00:00 EDT 2015), {And=[(loanType = 2), {Or=[{And=[{Not=[(specialFeaturesString like "*003* ")]}, {Not=[(specialFeaturesString like "*007*")]}]}, (specialFeaturesString like "*007*")]}, (specialFeaturesString like "*808*")]}]}

I would like to covert the above string to json format like below

{ "condition": "AND", "rules": [ { "id": "eDate", "field": "eDate", "type": "date", "input": "text", "operator": "greater_or_equal", "value": "2015/09/01" }, { "condition": "AND", "rules": [ { "id": "loanType", "field": "loanType", "type": "string", "input": "text", "operator": "equal", "value": "2" }, { "condition": "OR", "rules": [ { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "equal", "value": "*707*" }, { "condition": "AND", "rules": [ { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "not_equal", "value": "*003*" }, { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "not_equal", "value": "*007*" } ] } ] }, { "id": "specialFeatureText", "field": "specialFeatureText", "type": "string", "input": "text", "operator": "equal", "value": "*808*" } ] } ] }

I may have to create POJOs and loop through the Map to to achieve this. Perhaps some recursion is involved.

I eventually feed the above json to jquery querybuilder.

Thank you for your help.

You can use Jackson JSON serializer to convert your HashMap or POJO to JSON in appropriate format. E.g.:

Map<String, Object> mapMatchingJsonStructure = ...
OutputStream out = // where you want to write the output
new ObjectMapper().writeValue(out, mapMatchingJsonStructure);

Also Cayenne has a plist parser in cayenne-wocompat. This is less relevant to you, as you already have your plist parsed. But I thought I'd mention.
