有没有办法告诉 PowerMock 不要对通过 java 反射实例化的所有对象使用 MockClassLoader？

Question

我看到 serviceClass classloader 类型是 MockClassLoader。有什么办法可以防止这种情况发生吗？ @PowerMockIgnore 是唯一的选择吗？

class A 使用powermock 运行并通过反射调用class B 的方法

@RunWith(PowerMockRunner.class)
public class A {
@Test 
public void testA() throws ClassNotFoundException, InstantiationException, IllegalAccessException, NoSuchMethodException, SecurityException, IllegalArgumentException, InvocationTargetException{
    Class<?> serviceClass = Class.forName(B.class.getName());
    Object serviceStub = serviceClass.newInstance();
    Method method = serviceClass.getMethod("fun");
    method.invoke(serviceStub);
    }
}

class B{
public void fun(){
     System.out.println("fun!");
    }
}

Answer 1

如果加载class，那么可以指定class加载器，例如：

@RunWith(PowerMockRunner.class)
public class A {
   @Test 
   public void testA() throws ClassNotFoundException, InstantiationException, IllegalAccessException, NoSuchMethodException, SecurityException, IllegalArgumentException, InvocationTargetException{
       ClassLoader classLoader = ClassLoader.getSystemClassLoader();
       Class<?> serviceClass = Class.forName(B.class.getName(), true, classLoader);
       Object serviceStub = serviceClass.newInstance();
       Method method = serviceClass.getMethod("fun");
       method.invoke(serviceStub);
   }
}

但是如果你希望class在隐式加载时不会被MockClassloader加载，那么使用@PowerMockIgnore是唯一的方法。

Is there any way to tell PowerMock not to use MockClassLoader for all objects which are instantiated via java reflection?

junit

powermock
