Is there a way to do deep comparison on a nested property with Hamcrest

I use hamcrest for most of my testing ,but have encountered a issue with it not being able to test a property one level down in the object graph .A snipped of my test case is below

final List<Foo> foos= fooRepository.findAll(spec);
      assertThat(results, is(notNullValue()));
      assertThat(results, hasItem(hasProperty("id.fooID1", equalTo("FOOID1"))));

so here I want to check if in the list of foos I have a property id.fooID1 equla to FOOID1 .Here I am going one level down to check my nested property .This doesnt currently work in hamcrest and I get the following error.

java.lang.AssertionError: 
Expected: a collection containing hasProperty("id.fooID1", "FOOID1")
     but: No property "id.fooID1"
    at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20)
    at org.junit.Assert.assertThat(Assert.java:956)
    at org.junit.Assert.assertThat(Assert.java:923)

any help or workaround on this issue .
