如何获取父基类对象 super.getClass() [英] How to get the parent base class object super.getClass()

问题描述

我对 Java 有一个小问题(作为一名 C++ 程序员).

I have a little problem with Java (being a C++ programmer).

我有 2 个相关的课程:

I have 2 related classes:

public class Patient() {
...
}

public class PatientPersistent extends Patient {
...
    public void foo() {
    System.out.println(super.getClass().toString());
    }
}

这将输出:

类 org.example.smartgwt.server.model.PatientPersistent

class org.example.smartgwt.server.model.PatientPersistent

有没有办法获取父类类型?即

Is there a way to get the parent class type? i.e.

类 org.example.smartgwt.server.model.Patient.

class org.example.smartgwt.server.model.Patient.

这将使我能够概括一些我需要在每个孩子身上实施的方法，这很糟糕.

This will allow me to generalize some methods which I need to implement in each child which is awful.

谢谢！

我正在使用 Dozer 将我的域 Hibernate 对象转换为可序列化版本.我不想让客户知道这一点，所以客户只能看到 Patient 类.在服务器端，我执行转换.

I'm using Dozer to convert my domain Hibernate object to a Serializable version. I don't want the client to know of this, so the client only sees the Patient class. On the server side I perform conversions.

public class DataObject<Type> {

    private static final Class<Object> DstType = Type;

    public Object convert(Object srcData, final BeanFactory factory) {
        Mapper mapper = (Mapper)factory.getBean("dozerMapper");

        return (Object)mapper.map(srcData, DstType);
    }
}

public class Patient() implements Serializable {
    public Set foo;
}    

public class PatientPersistent extends Patient {

    public org.hibernate.collection.PersistentSet foo;
    DataObject<Patient> converter = new DataObject<Patient>;

    public Patient convertToSerializable(final BeanFactory factory) {
        return (Patient)converter.convert(this, factory);
    }
}

public class main() {
    // This object is not serializable so I cannot send it to the client
    PatientPersistent serializableBar = new PatientPersistent();

    // Using Dozer to copy the data PatientPersistent -> Patient
    // This will load the Dozer spring bean and copy as mapped
    Patient copiedSerializableData = serializableBar.convertToPersistent(bar, factory);
}

我知道这段代码不起作用，但这只是为了表明我的观点.我希望能够将对象转换到它的可序列化形式，以便我可以将它发送回客户端.这就是为什么我想给父母的类型.调用 ma​​pper 总是相同的，一个源对象和一个 Dest.class.

I know this code does not work, but it's just to make my point. I would like to be able to convert the object to it's serializable form so that I can send it back to the client. That's why I would like to give the parent's type. Calling the mapper will always be the same thing, a source object and a Dest.class.

也许我对 Java 太困惑了.

Maybe I'm just too confused with java.

谢谢

推荐答案

getClass().getSuperclass()

但是不要使用这个.这当然是糟糕设计的标志.

But don't use this. It is certainly a sign of bad design.
