耗时:

protoBuf: 93 毫秒

单行数据大小

JDK: 

 

protoBuf: 

 

 

JSON:

 

JDK使用ProtoBuf 生成的 java 文件类生产,看起来有很多垃圾数据

这次用 普通JAVA 类,写一个差不多结构的再试一次

    @Getter
    @Setter
    public static class Message implements Serializable {

        private static final long serialVersionUID = -7270500345236168152L;

        //消息类型
        private Byte type;

        //消息长度
        private Integer length;

        private Long id;

        //消息体
        private String msgBody;

        public Message(Byte type, Integer length, Long id, String msgBody) {
            this.type = type;
            this.length = length;
            this.id = id;
            this.msgBody = msgBody;
        }

        @Getter
        public enum Type {
            ACTIVE((byte) 0x00, "激活"), MESSAGE((byte) 0x01, "消息");

            //状态代码
            private Byte code;
            //状态名称
            private String name;


            //构造方法
            Type(Byte code, String name) {
                this.code = code;
                this.name = name;
            }

            //根据code获取状态名称
            public static String getNameByCode(Byte code) {
                for (Type item : Type.values())
                    if (item.getCode().equals(code))
                        return item.getName();
                return "";
            }
        }

    }

 

    //JDK
    @Test
    public void add() {
        BoundSetOperations<String, MessageProtoTest.Message> operations = redisTemplate.boundSetOps("message4");
        long begin = System.nanoTime();
        for (int i = 0; i < 100; i++)
            operations.add(new MessageProtoTest.Message(Message.Type.ACTIVE.getCode(),10,(long)i,"你好啊"));

        System.out.println((System.nanoTime() - begin) / 1000000);

    }

结果: 耗时  137毫秒

单行数据大小: 

看起来更糟糕

Message.proto

syntax = "proto3";
option java_package = "com.lzw.protobuf";
option java_outer_classname = "MessageProto";
message Message {

    int32 type = 1;

    int32 length = 2;

    int32 id = 3;

    string msgBody = 4;

    enum Type {
        ACTIVE = 0;
        MESSAGE = 1;
    }

}
