MockMvc和Spring Security - Null FilterChainProxy

我需要使用Spring Security测试我们的REST控制器.我正在使用MockMvc作为弹簧安全参考建议

http://docs.spring.io/spring-security/site/docs/4.0.x/reference/htmlsingle/#test-mockmvc

测试:

@ContextConfiguration(locations = "classpath:applicationContext.xml")
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class LikesTest {

    protected MockMvc mockMvc;

    @Autowired
    private WebApplicationContext context;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders
                .webAppContextSetup(context)
                //.standaloneSetup(new MessageController())
                .apply(SecurityMockMvcConfigurers.springSecurity())
                .build();
    }

    @Test
    @WithMockUser("user")
    public void testAddLike() throws Exception {
        mockMvc.perform(get("/like?msgId=4&like=false"));
    }
}

当我正在运行JUnit测试时,我正在获得此故障跟踪

org.springframework.security.web.FilterChainProxy.getFilters(FilterChainProxy.java:223)中的java.lang.NullPointerException

另外如果删除applicationContext.xml中的bean:

然后我得到了这个失败的痕迹:

java.lang.IllegalStateException:springSecurityFilterChain不能为null.确保使用名称为springSecurityFilterChain的Bean实现Filter,或者注入要使用的Filter.在org.springframework.security.test.web.servlet.setup.SecurityMockMvcConfigurer.beforeMockMvcCreated(SecurityMockMvcConfigurer.java:62)

我不知道为什么FilterChainProxy为null.在我的Web.xml中,我已经使用filter-name springSecurityFilterChain声明了DelegatingFilterProxy,我的应用程序运行正常.请帮我!谢谢
