How to parse Json in Java?

Question

Java

I am using jackson databind object.
I get the following Json:

{mode=, hdfsPath=, firstRowAsHeader=false, columns=[], totalRows=null}

I'm trying to parse it using the objectMapper.readTree(json) method, but due to the fact that json is not standard, an Exception is thrown:

Unexpected character ('=' (code 61)): was expecting a colon to separate field name and value
 at [Source: (String)"..."]

The following configurations are currently applied to the object: ALLOW_UNQUOTED_FIELD_NAMES (true); (FAIL_ON_UNKNOWN_PROPERTIES (false).
What other configuration needs to be added to make it work?

Answer 1

It's not json at all. So I doubt that the json parser will be able to parse this with any settings.

Answer 2

As noted above, this is not JSON; if memory serves me, this is the result of map.toString().
To get JSON, you need to use ObjectMapper:

String json = objectMapper.writeValueAsString(map);
