为什么AntPathRequestMatcher与该MockHttpServletRequest不匹配？我希望以下测试通过：

@Test
public void matcherMatches() {
    MockHttpServletRequest req = new MockHttpServletRequest("GET","/login");
    AntPathRequestMatcher matcher = new AntPathRequestMatcher("/login/**");
    Assert.assertTrue(matcher.matches(req));
}

但事实并非如此-我缺少MockHttpServletRequest方面的信息？
