protobuf 序列化和反序列化

        Student.Builder builder = Student.newBuilder();
        builder.setId(1);
        builder.setName("段小秋");
        builder.setEmail("31346337@qq.com");
        //序列化
        Student stu = builder.build();
        System.out.println(stu);
        byte[] data = stu.toByteArray();
        Student student = Student.parseFrom(data);
        System.out.println(student);
