fst是完全兼容JDK序列化协议的系列化框架，序列化速度大概是JDK的4-10倍，大小是JDK大小的1/3左右。
首先引入pom
de.ruedigermoeller
fst
2.04
测试代码
package zookeeper.seria;
import java.io.Serializable;
public class FSTSeriazle { public static void main(String[] args) {
User bean = new User();
bean.setUsername("xxxxx");
bean.setPassword("123456");
bean.setAge(1000000);
System.out.println("序列化 ， 反序列化 对比测试：");
long size = 0;
long time1 = System.currentTimeMillis();
for (int i = 0;
i < 10000;
i++) {
byte[] jdkserialize = JRedisSerializationUtils.jdkserialize(bean);
size += jdkserialize.length;
JRedisSerializationUtils.jdkdeserialize(jdkserialize);
}
System.out.println("原生序列化方案[序列化10000次]耗时："
+ (System.currentTimeMillis() - time1) + "ms size:=" + size);
size = 0;
long time2 = System.currentTimeMillis();
for (int i = 0;
i < 10000;
i++) {
byte[] serialize = JRedisSerializationUtils.serialize(bean);
size += serialize.length;
User u = (User) JRedisSerializationUtils.unserialize(serialize);
}
System.out.println("fst序列化方案[序列化10000次]耗时："
+ (System.currentTimeMillis() - time2) + "ms size:=" + size);
size = 0;
long time3 = System.currentTimeMillis();
for (int i = 0;
i < 10000;
i++) {
byte[] serialize = JRedisSerializationUtils.kryoSerizlize(bean);
size += serialize.length;
User u = (User) JRedisSerializationUtils.kryoUnSerizlize(serialize);
}
System.out.println("kryo序列化方案[序列化10000次]耗时："
+ (System.currentTimeMillis() - time3) + "ms size:=" + size);
}}class User implements Serializable{ private String username;
private int age;
private String password;
public String getUsername() {
return username;
} public void setUsername(String username) {
this.username = username;
} public int getAge() {
return age;
} public void setAge(int age) {
this.age = age;
} public String getPassword() {
return password;
} public void setPassword(String password) {
this.password = password;
}}
结果
序列化 ， 反序列化 对比测试：
原生序列化方案[序列化10000次]耗时：458ms size:=1160000
fst序列化方案[序列化10000次]耗时：184ms size:=550000
kryo序列化方案[序列化10000次]耗时：462ms size:=390000
