Protostuf序列化

工具对比

JdkSerialize: java内置的序列化能将实现了Serilazable接口的对象进行序列化和反序列化，ObjectOutputStream的writeObject0方法可序列化对象生成字节数组

Protostuf:google开源的protostuf采用更为紧凑的二进制数组，表现更加优异，然后使用protostuff的编译工具生成pojo类

代码实现

导入依赖

    io.protostuff
    protostuff-core
    1.6.0



    io.protostuff
    protostuff-runtime
    1.6.0

创建工具类

import io.protostuff.LinkedBuffer;
import io.protostuff.ProtostuffIOUtil;
import io.protostuff.Schema;
import io.protostuff.runtime.RuntimeSchema;

public class ProtostuffUtil {

    /**
     * 序列化
     * @param t
     * @param 
     * @return
     */
    public static  byte[] serialize(T t){
        Schema schema = RuntimeSchema.getSchema(t.getClass());
        return ProtostuffIOUtil.toByteArray(t,schema,
                LinkedBuffer.allocate(LinkedBuffer.DEFAULT_BUFFER_SIZE));

    }

    /**
     * 反序列化
     * @param bytes
     * @param c
     * @param 
     * @return
     */
    public static  T deserialize(byte []bytes,Class c) {
        T t = null;
        try {
            t = c.newInstance();
            Schema schema = RuntimeSchema.getSchema(t.getClass());
            ProtostuffIOUtil.mergeFrom(bytes,t,schema);
        } catch (InstantiationException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }
        return t;
    }

}
