Java Spring模拟junit测试在Spring security 3.2.0.RC1版本中抛出NullPointerException

我有一个junit测试，它使用SpringMockMVC执行一个请求

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..)
}

测试运行得很好，直到我将SpringSecurityLibs版本提升到3.2.0.RC1。 现在，我在以下位置获得NullPointerException：

ResultActions perform = mvc.perform(builder);

stacktrace是：

我不知道该怎么办。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

您好，

正如M.Deinum所说，我必须在SecurityContextHolderAwareRequestFilter上调用AfterPropertieSet方法。因此，设置方法如下所示：

@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);
}

考虑联系Spring Security DeV，如果可能的话，可能会对此提出错误。测试设置代码是错误的。Spring Security中的大多数过滤器实现了通常由Spring容器调用的

初始化bean

。但您的安装代码无法调用此函数。SecurityContextHolderAwareRequestFilter的3.2版本在该方法中进行了一些附加设置，以检测Servlet 3.0与否。
