测试类1

package reflectPrivateMethod;

public class Test1 {
	//私有方法
	private void func1() {
		System.out.println("this is a private method!");
	}
}

测试类2

package reflectPrivateMethod;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

public class Test2 {
	public static void main(String[] args) throws ClassNotFoundException, NoSuchMethodException, SecurityException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
		run();
	}
	
	public static void run() throws ClassNotFoundException, NoSuchMethodException, SecurityException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
		//获取类class信息
		Class c=Class.forName("reflectPrivateMethod.Test1");
		//通过class信息实例化对象
		Test1 t1=(Test1)c.newInstance();
		//获取该类声明的私有方法
		Method m=c.getDeclaredMethod("func1", null);
		//打开权限
		m.setAccessible(true);
		//调用方法
		m.invoke(t1, null);
	}
