How to parse JSON in Java
(36 answers)
Closed 3 years ago.
I receive this string in json format from my frontend:
{"hosts":[{"name":"localhost"},{"name":"localhost"},{"name":"localhost"}]}
What I want to do is to iterate each one of the hosts and print their name.
How do I map my string to do that using java?
You can convert String to JsonObject with Gson
Other option: use Jackson lib to convert Json string to Java Object

I got the following response from the server using Java
{"success":true,"errors":[],"requestId":"blah blah","warnings":[],"result":[{"id":1023,"name":"Email","description":"", subject":{"type":"Text","value":"Some value"}}]
I want to access the id and subject's -> value. Thanks in advance.
You can use this library
JacksonXML
To parse this JSON response to Java object, and next validate it, in your custom conditions.
There are also similar libraries like gson from Google or Xpath. I recommend Jackson because Spring framework use this and it's very easy to use in production grade.

Converting JSON data to Java object

I have one map file
Map<String,Object> personData = procReadData.execute(in);
The data is coming from this is
{CUR_GENERIC=[{PROPOSAL_NUMBER=1, TITLE=test proposal, LEAD_UNIT_NAME=University, FULL_NAME=test, STSTUS_CODE=Pending, DOCUMENT_TAKEN_BY=user1 qa, UPDATE_TIMESTAMP=2015-12-28 00:00:00.0, UPDATE_USER=test}]}
How to get PROPOSAL_NUMBER from that result.
You should check what type the result of
personData.get("CUR_GENERIC");
is (use a debugger for this if you have no documentation available). It's probably a list or an array of Map<String, Object> depending on what tool was used to convert the JSON data to a Java map. Get the first entry of this list or array and then use get("PROPOSAL_NUMBER") to retrieve the entry you want.
