Json

Json is the serialized json framework implemented by java.

Characteristics

8 basic types support

Basic types / object arrays / collections / enumerations / object support

Follow-up features of minimalist API

Support for @ Field annotations

Deserialization object integrity support, currently only supports basic deserialization. Why to create to solve the deficiency in fastJson

FastJSON has some limitations on serialization itself. When there is a collection in the object and the collection is still an object, the result is not satisfactory.

Lightweight and efficient

Json tools such as FastJson are rich in features, but they are too thoughtful and compatible.

It is hoped that by strictly controlling serialization and deserialization, the code will become efficient and lightweight and more suitable for its own usage scenarios.

Follow-up expansion

Follow-up serialization related, will use this tool to facilitate self-expansion of learning.
