java序列化与ObjectOutputStream和ObjectInputStream的实例详解

java序列化与objectoutputstream和objectinputstream的实例详解

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; 
  } 
 
}
