1 protostuff简介

protostuff是一个基于protobuf实现的序列化方法。

优点：不用写.proto文件。

2 springboot protobuf集成开发

第1步：pom文件引入：

       <dependency>
			<groupId>io.protostuff</groupId>
			<artifactId>protostuff-core</artifactId>
			<version>1.4.0</version>
		</dependency>
		<dependency>
			<groupId>io.protostuff</groupId>
			<artifactId>protostuff-runtime</artifactId>
			<version>1.4.0</version>
		</dependency>

第2步：序列化工具类：serializeUtil：

public class serializeUtil {
    public static byte[] serializeObjToByte(Heroic heroic) {
        if (heroic == null) {
            return null;
        }
        Schema<Heroic> schema = RuntimeSchema.getSchema(Heroic.class);
        LinkedBuffer buffer = LinkedBuffer.allocate(4096);
        byte[] protostuff = null;
        try {
            protostuff = ProtostuffIOUtil.toByteArray(heroic, schema, buffer);
        } finally {
            buffer.clear();
        }
        return protostuff;
    }

    public static List<byte[]> serializeListToByte(List<Heroic> list) {
        if (list == null || list.size() <= 0) {
            return null;
        }
        List<byte[]> bytes = new ArrayList<>();
        Schema<Heroic> schema = RuntimeSchema.getSchema(Heroic.class);
        LinkedBuffer buffer = LinkedBuffer.allocate(4096);
        byte[] protostuff = null;
        for (Heroic heroic : list) {
            try {
                protostuff = ProtostuffIOUtil.toByteArray(heroic, schema, buffer);
                bytes.add(protostuff);
            } finally {
                buffer.clear();
            }
        }
        return bytes;
    }

    public static Heroic deserializeByteToObj(byte[] bytes) {
        if (bytes == null) {
            return null;
        }
        Schema<Heroic> schema = RuntimeSchema.getSchema(Heroic.class);
        List<Heroic> list = new ArrayList<Heroic>();

        Heroic heroic = new Heroic();
        ProtostuffIOUtil.mergeFrom(bytes, heroic, schema);
        return heroic;
    }

    public static List<Heroic> deserializeByteToList(
            List<byte[]> bytesList) {
        if (bytesList == null || bytesList.size() <= 0) {
            return null;
        }
        Schema<Heroic> schema = RuntimeSchema.getSchema(Heroic.class);
        List<Heroic> list = new ArrayList<Heroic>();
        for (byte[] bs : bytesList) {
            Heroic product = new Heroic();
            ProtostuffIOUtil.mergeFrom(bs, product, schema);
            list.add(product);
        }
        return list;
    }
}
