一个测试的实体类：
public class Param implements Serializable {
private static final long serialVersionUID = 5187074869820982336L;
private Integer param1;
private String param2;
public Integer getParam1() {
return param1;
}
public void setParam1(Integer param1) {
this.param1 = param1;
}
public String getParam2() {
return param2;
}
public void setParam2(String param2) {
this.param2 = param2;
}
}
测试：
public class Main {
public static void main(String[] args) throws Exception {
SerializeParam();
Param param = DeserializeParam();
System.out.println(MessageFormat.format("param1={0},param2={1}", param.getParam1(), param.getParam2()));
}
/**
* 将实体类序列化到本地
* @throws FileNotFoundException
* @throws IOException
*/
private static void SerializeParam() throws FileNotFoundException, IOException {
Param param = new Param();
param.setParam1(123);
param.setParam2("asdf");
ObjectOutputStream oo = new ObjectOutputStream(new FileOutputStream( new File("E:/param.txt") ));
oo.writeObject(param);
System.out.println("Person对象序列化成功！");
oo.close();
}
/**
* 反序列化
* @return
* @throws Exception
* @throws IOException
*/
private static Param DeserializeParam() throws Exception, IOException {
ObjectInputStream ois = new ObjectInputStream(new FileInputStream( new File("E:/param.txt")));
Param param = (Param) ois.readObject();
System.out.println("Person对象反序列化成功！");
ois.close();
return param;
}
}
