从包中读取对象 - java

Question

如何从包中读取对象？ 我把我的对象放到myObject.data文件..

• 对象名称= myObject.data

• 包名称为= examplePackage

  MyObject value = null;
  try {
      try (ObjectInputStream is = new ObjectInputStream(new FileInputStream(
              "PACKAGE ....... ? myData.data""
      ))) {
          value = (MyObject) is.readObject();
      }
  } catch (IOException | ClassNotFoundException e) {
      System.out.println("Error: " + e);
  }
  return value;
  

我尝试了getClass().getResource()但无效

谢谢

按如下方式更改代码：

MyObject value = null;
try {
    try (ObjectInputStream is = new ObjectInputStream(
      getClass().getClassLoader().getResourceAsStream("data/hm_pj.data"); 
    ))) {
        value = (MyObject) is.readObject();
    }
} catch (IOException | ClassNotFoundException e) {
    System.out.println("Error: " + e);
}
return value;
