/**  * Created by zhangzh on 2017/2/20.  */
public class ProtoBufUtilTest {
    public static void main(String[] args) {
        Student student = new Student();      
        student.setName("lance");       
        student.setAge(28);       
        student.setStudentNo("2011070122");      
        student.setSchoolName("BJUT");
        byte[] serializerResult = ProtoBufUtil.serializer(student);
        System.out.println("serializer result:" + Arrays.toString(serializerResult));
        Student deSerializerResult = ProtoBufUtil.deserializer(serializerResult,Student.class);
        System.out.println("deSerializerResult:" + deSerializerResult.toString());     }
}
  

4.测试输出结果: 

serializer result:[10, 5, 108, 97, 110, 99, 101, 18, 10, 50, 48, 49, 49, 48, 55, 48, 49, 50, 50, 24, 28, 34, 4, 66, 74, 85, 84]

deSerializerResult:Student{name='lance', studentNo='2011070122', age=28, schoolName='BJUT'}
