Fastjson Deserialization: Key Features

Here are some features of fastjson deserialization:

1. Support for complex data types: fastjson is able to deserialize various complex data types, including objects, arrays, collections, and enums.
2. High performance: fastjson offers a high-performance deserialization method, allowing for quick parsing of JSON data and converting it into corresponding Java objects.
3. Flexibility: fastjson can automatically match the corresponding Java object properties based on the field names in the JSON data, or manually map them using annotations, etc.
4. Support for custom deserialization rules: fastjson allows for custom deserialization rules by implementing specific interfaces or annotations to specify the deserialization method for fields.
5. Security: fastjson has taken certain considerations for security during the deserialization process, effectively preventing some common deserialization vulnerabilities.
6. Cross language support: Fastjson supports cross-language serialization and deserialization, allowing Java objects to be serialized into JSON data and then deserialized in other languages.

It is important to note that there are security risks in the deserialization process of fastjson, such as the potential for deserialization attacks. Therefore, when using fastjson for deserialization, it is necessary to carefully consider the reliability of the data source and take appropriate security measures.
