String length (5046272) exceeds the maximum length (5000000)

mapper.readValue(s ,JSONObject.class);
When I converted the string again, the conversion failed because the string was too long。
Throw exception：String length (5046272) exceeds the maximum length (5000000)。
What should I do about it。

There is configuration in jackson-core called StreamReadConstraints (I think depends on the version).

Which version of Jackson are u using?

Sounds like this is the original 2.15.0 or such; default max length was raised to 20M in 2.15.1.

So @chenjianbo0705 first maybe try upgrading Jackson version.
