序列化和反序列化实现

使用事例

  • 定义pojo 如果使用JDK方式，还需要实现Serializable接口
@Data
@Builder
public class model.User implements Serializable {

    private  String  name;
    private  int age;
}
model.User user = model.User.builder().name("用户"+i).age(i).build();
private AbstractSerialize  serialize = new ProtostuffSerializeUtil();
byte[] body = serialize.serialize(msg);
model.User user1 = serialize.deserialize(body,model.User.class);

测试

测试类

综合来看,hessian 的效率是比较高的。fastjson效率相对偏低。
