I'm sure I'm missing something simple. bar gets autowired in the junit test, but why doesn't bar inside foo get autowired?

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"beans.xml"})
public class BarTest {  

    @Autowired
    Object bar;

    @Test
    public void testBar() throws Exception {
            //this works
        assertEquals("expected", bar.someMethod());
            //this doesn't work, because the bar object inside foo isn't autowired?
        Foo foo = new Foo();
        assertEquals("expected", foo.someMethodThatUsesBar());
    }
}
