How to parse a JSON string into JsonNode in Jackson?

Question

It should be so simple, but I just cannot find it after being trying for an hour #embarrasing.

I need to get a JSON string, for example, {\"k1\":v1,\"k2\":v2}<

Richard's answer is correct. Alternatively you can also create a MappingJsonFactory (in org.codehaus.jackson.map) which knows where to find ObjectMapper. The error you got was because the regular JsonFactory (from core package) has no dependency to ObjectMapper (which is in the mapper package).

But usually you just use ObjectMapper and do not worry about JsonParser or other low level components -- they will just be needed if you want to data-bind parts of stream, or do low-level handling.
