## 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;
        }
    }
