Question

我有一个junit测试，它使用Spring MockMvc执行请求。

private MockMvc mvc;

@Before
public void setUp() {
    mvc = MockMvcBuilders.standaloneSetup(new LoginController())
            .addFilter(new AnonymousAuthenticationFilter("anonymous"))
            .addFilter(new SecurityContextHolderAwareRequestFilter())
            .addFilter(new XssValidationFilter()).build();
    SecurityContextHolder.getContext().setAuthentication(null);
}

@Test
public void test() throws Exception {
    MockHttpServletRequestBuilder builder = MockMvcRequestBuilders.get("/login.htm")
            .param(USER, "admin").param(PASSWORD, "pass");
    ResultActions perform = mvc.perform(builder);
    (assertions..)
}

测试工作正常，直到我将spring-security libs版本提升到3.2.0.RC1。现在，我得到NullPointerException：

ResultActions perform = mvc.perform(builder);

堆栈跟踪是：

我不知道该怎么做。如何修复该测试？我需要这个新版本的spring-security，因为它支持CSRF攻击预防。

问候，彼得。

正如M. Deinum所说，我不得不在SecurityContextHolderAwareRequestFilter上调用afterPropertiesSet方法。所以setUp方法看起来像这样：

@Before
public void setUp() throws ServletException {
    Mockito.reset(userGroupInfo, licenseManager);
    SecurityContextHolderAwareRequestFilter securityContextHolderAwareRequestFilter = new SecurityContextHolderAwareRequestFilter();
    securityContextHolderAwareRequestFilter.afterPropertiesSet();
    mvc = MockMvcBuilders.standaloneSetup(new LoginController(userGroupInfo, licenseManager, userInfo))
            .addFilter(new AnonymousAuthenticationFilter("anonymous"))
            .addFilter(securityContextHolderAwareRequestFilter)
            .addFilter(new XssValidationFilter()).build();
    SecurityContextHolder.getContext().setAuthentication(null);
}

Spring模拟的junit测试使用spring-security 3.2.0.RC1版本抛出NullPointerException
