我正在尝试将OBJ保存在文件中,但是java.io.notserializable Exception错误不允许我这样做。这是我的代码:
import Estrategia.Gestor_nivel;
import Resources.Exceptions.DuplicateLevelsId;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import pp_epoca_normal.Gerir_jogo;
public class Teste {
public void guardar_ficheiro(Object obt) {
Gerir_jogo teste = (Gerir_jogo) obt;
System.out.println("sad---- " + teste);
Gestor_nivel sad;
try {
ObjectOutputStream objOut = new ObjectOutputStream(new FileOutputStream("teste.dat"));
ObjectOutputStream objOut1 = new ObjectOutputStream(new FileOutputStream("teste1.dat"));
objOut.writeObject(teste);
objOut1.writeObject(teste.getObjetos());
sad = (Gestor_nivel) teste.getLevel(0);
objOut.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public void ler_ficheiro() throws FileNotFoundException, IOException, ClassNotFoundException, DuplicateLevelsId {
Gerir_jogo asd;
ObjectInputStream mySecondStream = new ObjectInputStream(new FileInputStream("teste.dat"));
ObjectInputStream mySecondStream1 = new ObjectInputStream(new FileInputStream("teste1.dat"));
asd = (Gerir_jogo) mySecondStream.readObject();
asd.setObjetos((Object[]) mySecondStream1.readObject());
System.out.println("leu--");
mySecondStream.close();
mySecondStream1.close();
}
}

有人可以帮我吗?我真的需要放这个保存和读取文件,以及其中的内容
错误:
java.io.NotSerializableException: pp_epoca_normal.Gerir_jogo
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1184)
at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:348)

at pp_epoca_normal.PP_epoca_normal.main(PP_epoca_normal.java:77)
我真的不知道该怎么办
您的类Gerir_jogo
必须实现接口可序列化。请看一下本教程。
编辑1
您的班级不会实现它,因此,如果是:
进行更改import java.io.Serializable;
public class Gerir_jogo extends Contentor implements GameContainerContract, Serializable {
在gerir_jogo类上实现序列化。更改类声明为:
import java.io.Serializable;
public class Gerir_jogo extends Contentor implements GameContainerContract, Serializable {
序列化java对象意味着将字节信息作为对象的非静态状态流传输到外部文件。在这里,必须通过" serilizable"接口实现。
在这里,我回复了一个代码,该代码将状态复制为ID,NAME&班级"员工"的sal到目的地存在的外部文件" d: object states.txt"。这里是不可读的。
import java.io.FileOutputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;
public class Employee implements Serializable {
int id;
String name;
double sal;
public Employee(int id, String name, double sal) {
super();
this.id = id;
this.name = name;
this.sal = sal;
}
public String toString() {
return "Employee [id=" + id + ", name=" + name + ", sal=" + sal + "]";
}
public static void main(String[] args) throws Exception {
Employee e1 = new Employee(101, "Mr. S.V. Roshan", 45000.0D);
FileOutputStream fout = new FileOutputStream("D:/Object/State.txt");
ObjectOutputStream out = new ObjectOutputStream(fout);
out.writeObject(e1);
out.flush();
out.close();
fout.flush();
fout.close();
System.out.println("Object serialized successfully!");
}
}
我想,它可能会对您有所帮助..!
