java序列化与ObjectOutputStream和ObjectInputStream的实例详解

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;   }  } 

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;   }  }
