fast-serialization
简介
FST is fast java serialization drop in-replacement。
特性
up to 10 times faster 100% JDK Serialization compatible drop-in replacement (Ok, might be 99% ..). As an example: Lambda Serialization which came with 1.8 worked instantly.
Android compatible since version >= 2.17 (use FSTConfiguration.createAndroidDefaultConfiguration() both on server and client side. The configuration object has to be passed into FSTObjectIn/Output constructors)
OffHeap Maps, Persistent OffHeap maps
FSTStructs is very similar to IBM’s packed objects.
Difference is: You can run it with Oracle JDK today.
optionally en/decode any Serializable object graph to JSON (incl. shared references) (since 2.29) for interop Apache 2.0 license since 2.17
使用案例

简单使用
As I constantly see people tinkering with ByteArrayOutputStreams and stuff (very inefficent), so here is the simplest way of using fast serialization (threadsafe)
static FSTConfiguration conf = FSTConfiguration.createDefaultConfiguration();
// maybe register most frequently used classes on conf
[...]
// write
byte barray[] = conf.asByteArray(mySerializableObject);
[...]
// read
MyObject object = (MyObject)conf.asObject(barray);
