如何单元测试spring security@preauthorize（hasRole）？

Question

实际：200

我在MyController中有以下方法：

@PreAuthorize(value = "hasRole('MY_ROLE') and hasRole('MY_SECOND_ROLE')")
@RequestMapping(value = "/myurl", method = RequestMethod.GET)
public String loadPage(Model model, Authentication authentication, HttpSession session) {
    ...stuff to do...
}

我创建了以下abstract-security-test.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:security="http://www.springframework.org/schema/security"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.2.xsd">

    <security:global-method-security secured-annotations="enabled" />

    <security:authentication-manager alias="authManager">
        <security:authentication-provider>
            <security:user-service>
                <security:user name="missingsecondrole" password="user" authorities="MY_ROLE" />
            </security:user-service>
        </security:authentication-provider>
    </security:authentication-manager>

</beans>

@ContextConfiguration("classpath:/spring/abstract-security-test.xml")
public class MyTest {
    private final MyController myController = new MyController();
    @Autowired
    private AuthenticationManager manager;

    @Test
    public void testValidUserWithInvalidRoleFails() throws Exception {
        MockMvc mockMvc = standaloneSetup(myController).setViewResolvers(viewResolver()).build();

        Authentication auth = login("missingsecondrole", "user");

        mockMvc.perform(get("/myurl")
            .session(session)
            .flashAttr(MODEL_ATTRIBUTE_NAME, new ModelMap())
            .principal(auth)).andExpect(status().isUnauthorized());
    }

    protected Authentication login(String name, String password) {
        Authentication auth = new UsernamePasswordAuthenticationToken(name, password);
        SecurityContextHolder.getContext().setAuthentication(manager.authenticate(auth));
        return auth;
    }

    private ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("WEB-INF/views");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }
}

Answer 1

Spring Security 4提供了与mockmvc集成的全面支持。例如：

import static org.springframework.security.test.web.servlet.setup.SecurityMockMvcConfigurers.*;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
@WebAppConfiguration
public class SecurityMockMvcTests {

    @Autowired
    private WebApplicationContext context;

    private MockMvc mvc;

    @Before
    public void setup() {
        mvc = MockMvcBuilders
                .webAppContextSetup(context)
                .apply(springSecurity())
                .build();
    }

    @Test
    public void withUserRequestPostProcessor() {
        mvc
            .perform(get("/admin").with(user("admin").roles("USER","ADMIN")))
            ...
    }

    @WithMockUser(roles="ADMIN")
    @Test
    public void withMockUser() {
        mvc
            .perform(get("/admin"))
            ...
    }

 ...

问题所在

问题是设置SecurityContextHolder在此实例中不起作用。原因是，SecurityContextPersistenceFilter将使用SecurityContextRepository尝试从HttpServletRequest（默认情况下使用HttpSession）中找出SecurityContext。它找到（或未找到）的SecurityContext将覆盖您在SecurityContextHolder上设置的SecurityContext。

private SecurityContextRepository repository = 
      new HttpSessionSecurityContextRepository();

private void login(SecurityContext securityContext, HttpServletRequest request) {
    HttpServletResponse response = new MockHttpServletResponse();

    HttpRequestResponseHolder requestResponseHolder = 
          new HttpRequestResponseHolder(request, response);
    repository.loadContext(requestResponseHolder);

    request = requestResponseHolder.getRequest();
    response = requestResponseHolder.getResponse();

    repository.saveContext(securityContext, request, response);
}

让它变得更容易

如果您希望使与MockMvc的这种和其他安全相关的交互变得更容易，可以参考gs-spring-security-3.2示例应用程序。在该项目中，您将找到一些用于使用Spring Security和MockMvc的实用程序，称为SecurityRequestPostProcessors。要使用它们，您可以将前面提到的类复制到项目中。使用此实用程序将允许您编写类似于以下内容的内容：

RequestBuilder request = get("/110")
    .with(user(rob).roles("USER"));

mvc
    .perform(request)
    .andExpect(status().isUnAuthorized());

注意：不需要在请求上设置主体，因为只要用户通过身份验证，Spring Security就会为您建立主体。

您可能会问，为什么默认情况下不包含这一点。答案是，我们根本没有时间来完成3.2的时间线。示例中的所有代码都可以正常工作，但我们对命名约定以及如何集成以发布该代码的问题没有足够的信心。您可以跟踪SEC-2015，它将与Spring Security 4.0.0.M1一起发布。

更新

MockMvc实例还需要包含SpringSecurityFilterChain。为此，您可以使用以下方法：

@Autowired
private Filter springSecurityFilterChain;

@Test
public void testValidUserWithInvalidRoleFails() throws Exception {
    MockMvc mockMvc = standaloneSetup(myController)
        .addFilters(springSecurityFilterChain)
        .setViewResolvers(viewResolver())
        .build();
    ...
