以下示例显示java.io.ObjectInputStream.resolveProxyClass()方法的用法。
package com.jc2182;
import java.io.*;
public class ObjectInputStreamDemo extends ObjectInputStream {
public ObjectInputStreamDemo(InputStream in) throws IOException {
super(in);
}
public static void main(String[] args) {
String s = "Hello World";
try {
// create a new file with an ObjectOutputStream
FileOutputStream out = new FileOutputStream("test.txt");
ObjectOutputStream oout = new ObjectOutputStream(out);
// write something in the file
oout.writeUTF(s);
oout.flush();
// create an ObjectInputStream for the file we created before
ObjectInputStreamDemo ois = new ObjectInputStreamDemo(new FileInputStream("test.txt"));
// create a list that will be used to resolve proxy class
String[] list = {Serializable.class.getName()};
// print the class proxy
System.out.println("" + ois.resolveProxyClass(list));
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
class com.sun.proxy.$Proxy0
