• Java中的关键字---transient


        

    transient关键字的作用是在对象的序列化中体现的,如果一个类的变量被transient修饰,那么这个对象在序列化的过程中,不会序列化这个变量。在反序列的过程中,也不会反序列这个变量。
     1 @Data
     2 public class User implements Serializable{
     3     private transient String name;
     4     private String desc;
     5 }
     6  
     7 @Test
     8 public void fun1() {
     9     User user = new User();
    10     user.setDesc("sss");
    11     user.setName("zhangsan");
    12     System.out.println("序列化之前 "+user.toString());
    13  
    14     String path = "D:/test.txt";
    15     try {
    16         ObjectOutputStream outputStream = new ObjectOutputStream(new FileOutputStream(path));
    17         outputStream.writeObject(user);
    18  
    19         ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream(path));
    20         user = (User) objectInputStream.readObject();
    21         System.out.println("序列化之后 "+user.toString());
    22     } catch (IOException e) {
    23         e.printStackTrace();
    24     } catch (ClassNotFoundException e) {
    25         e.printStackTrace();
    26     }
    27 }
    输出结果:
    序列化之前  User(name=zhangsan, desc=sss)
    序列化之后  User(name=null, desc=sss)
