How to mock object initialized in method

Question

I have two obj, obj1 and obj2, obj2 is attribute in obj1 as

public class MyObject1
{
    MyObject2 myObject2;

    public MyObject2 getMyObject2()
    {
        return myObject2;
    }

    public void setMyObject2(MyObject2 myObject2)
    {
        this.myObject2 = myObject2;
    }
}

In my service, it is initialized obj1, and get obj2 as

public void myTest2(){
        MyObject1 myObject1 = new MyObject1();
        MyObject2 myObject2 = myObject1.getMyObject2();
}

In my test, I mock the obj2, I want when(obj1.getObj2).thenReturn(obj2), this obj2 is the mock object, as

public void test3(){
        MyObject2 myObject2 = mock(MyObject2.class);
        MyObject1 myObject1 = spy(new MyObject1());
        doReturn(myObject2).when(myObject1).getMyObject2();
        myService.myTest2();
} 

But now myObject2 I got from test is null, not the mocked myObject2. How can I get mocked myObject2 in my test?

Since we cannot use mockito without Reflection to mock a local variable, the problem is dead end for now
