Compare UUID in scope request

I have a bean in scope request that generate a unique UUID for each request. I want to write a test that verify that 2 requests have different UUID.

How can I run 2 request in the same test to compare there UUID ?

I already have a test that verify that the UUID is the same everywhere during one request.

public class RequestUUIDTests {

    @Autowired
    WebApplicationContext wac;

    @Autowired
    MockHttpServletRequest request;

    @Autowired
    RequestUUID requestUUID;

    @Test
    public void testRequestUUID() throws Exception {
        Assert.isTrue(requestUUID.toString().equals(request.getAttribute("scopedTarget.requestUUID").toString()));
        Assert.isTrue(requestUUID.toString().equals(wac.getBean("requestUUID", RequestUUID.class).toString()));
    }
}

If I run this test twice, I can see that the UUID is not the same. How can I test this automatically ?
