使用java中的jackson将json数组作为值添加到json键中

Question

I'm getting a result from mongo db as

 [{"k1":"v1"},{"k2":"v2"}]. 

How to convert this result into

{"key" : [{"k1":"v1"},{"k2":"v2"}] } 

using jackson.

Answer 1

Make a separate class 'Key' with those members and in your main class have an array of Keys like

Key keys[];

then use the ObjectMapper to parse the values from mongo and write them back again to get the output.
