java序列化框架码流、性能对比

本文对序列化框架：JDK、Kryo、Hession、FST、Fastjson、Gson进行对比，对比维度包括序列化后码流大小、10w次序列化反序列化性能耗时。

2、测试实体

package com.zhanghao.test.serialize;

import lombok.Getter;
import lombok.Setter;

import java.io.Serializable;

@Getter
@Setter
public class SerializeBO implements Serializable {
    private static final long serialVersionUID = -3109861179106944873L;
    private Integer a = 1;
    private Long b = 2L;
    private Byte c = 3;
    private Short d = 4;
    private Double e = 5.0;
    private Float f = 6.0F;
    private Boolean g  = true;
//    private Character h = 'h';
}
