How Java uses FST serialization and deserialization

FST (Fast Serialization) is an efficient Java serialization/deserialization framework. Compared to Java's built-in Serializable interface and other serialization frameworks, FST has faster speed and smaller serialization volume. It uses displacement based algorithms to optimize serialization and deserialization operations, which can provide advantages in performance and resource utilization. Introduction to FST serialization and deserialization methods: 1. FSTConfiguration. createDefaultConfiguration (): Create an instance of FSTConfiguration. The FSTConfiguration class is the core class of the FST framework, which provides a way to configure FST behavior. Example code: import org.nustaq.serialization.FSTConfiguration; FSTConfiguration conf = FSTConfiguration.createDefaultConfiguration(); 2. conf. asByteArray (obj): Serializes the given object into a byte array. Example code: byte[] serializedData = conf.asByteArray(obj); 3. conf. asObject (serializedData): Deserializes a byte array into the original object. Example code: Object obj = conf.asObject(serializedData); For the Maven project, the following dependencies can be added to the pom.xml file: <dependency> <groupId>de.ruedigermoeller</groupId> <artifactId>fst</artifactId> <version>2.59</version> </dependency> The version number in the above code may need to be changed according to the actual situation. Note: When using FST for serialization and deserialization, the serialized class needs to implement the Serializable interface and ensure that all its Member variable are also serializable.
