asp.net MVC 找不到Action 时的处理方法

实现序列化必须实现Serializable接口,可以在类中实现writeObject和readObject控制序列化过程,具体可以参考ArrayList的实现.

transient标识可以在序列化时忽略该字段

public class User implements Serializable{

private static final long serialVersionUID = 1L;
private transient String name;
private transient String password;
private transient Integer age;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = password;
}

public Integer getAge() {
return age;
}

public void setAge(Integer age) {
this.age = age;
}

@Override
public String toString() {
StringBuilder builder = new StringBuilder();
builder.append("User [name=").append(name).append(", password=")
.append(password).append(", age=").append(age).append("]");
return builder.toString();
}

private void writeObject(java.io.ObjectOutputStream s)
throws java.io.IOException{
s.writeUTF(name);
s.writeUTF(password);
s.writeInt(age);
}

private void readObject(java.io.ObjectInputStream s)
throws java.io.IOException, ClassNotFoundException {
name = s.readUTF();
password = s.readUTF();
age = s.readInt();
}
}

User user = new User();
user.setName("张三");
user.setPassword("12345678");
user.setAge(30);

ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(user);
oos.flush();
oos.close();

byte[] value = bos.toByteArray();

ByteArrayInputStream bis = new ByteArrayInputStream(value);
ObjectInputStream ois = new ObjectInputStream(bis);
user = (User) ois.readObject();
ois.close();

System.out.println(user);

结果为

User [name=张三, password=12345678, age=30]

其实在类里加writeObject和readObject方法和实现Externalizable没有什么区别
