Question

这是一个使用MVC控制器的Spring Boot 2.0.6应用程序，该控制器使用@PreAuthorize和＃oauth2.hasScope来保护控制器端点。我已经使用@WebMvcTest编写了编写控制器测试的测试。似乎正在发出请求，但是在调用#oauth2.hasScope时，它没有提供可与某个地方进行比较的值。我有什么问题？

例外

测试课程

@RunWith(SpringRunner.class)
@WebMvcTest
public class MockMvcTestBase {
    @Autowired
    protected WebApplicationContext context;

    private ObjectMapper objectMapper;

    private MockMvc mockMvc;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.context)
                .apply(documentationConfiguration(this.restDocumentation)
                        .uris()
                        .withScheme("http")
                        .withHost("development.com")
                        .withPort(80))
                .alwaysDo(document("{method-name}", preprocessRequest(prettyPrint()), preprocessResponse(prettyPrint())))
                .apply(springSecurity())
                .build();

        this.objectMapper = new ObjectMapper();
    }


@Test
@WithMockUser(username = "testclient", authorities = "foo")
public void givenValidUser_whenGetOrderDetailsWebEC_thenGetOrder() throws Exception {
    getMockMvc().perform(get("/ok")
            .header("Authorization", authorizationHeader()))
            .andExpect(status().isOk())
            .andExpect(content().string("ok"));
}
}

身份验证配置

@Configuration
@EnableAuthorizationServer
@EnableWebSecurity(debug = true)
@EnableGlobalMethodSecurity(prePostEnabled = true)
@SuppressWarnings("static-method")
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Bean
    public static PasswordEncoder passwordEncoder() {
        return NoOpPasswordEncoder.getInstance();
    }

    @Override
    public void configure(final ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
                .withClient("testclient")
                .secret("password")
                .authorizedGrantTypes("client_credentials")
                .accessTokenValiditySeconds(0)
                .scopes("foo")
                .and()
                .withClient("bar")
                .secret("password")
                .authorizedGrantTypes("client_credentials")
                .accessTokenValiditySeconds(0)
                .scopes("eq.distributor");
    }
}

控制器

@PreAuthorize("#oauth2.hasScope('foo')")
@RequestMapping(value = "/ok", method = RequestMethod.GET)
public String ok() {
    return "ok";
}

Spring Security调试输出

org.springframework.mock.web.MockHttpServletRequest@54704b46

servletPath:
pathInfo:/ok
headers: 
Authorization: Bearer 57962883-e379-433b-b613-1f888471fb84
Accept: application/json;charset=UTF-8


Security filter chain: [
  WebAsyncManagerIntegrationFilter
  SecurityContextPersistenceFilter
  HeaderWriterFilter
  LogoutFilter
  OAuth2AuthenticationProcessingFilter
  RequestCacheAwareFilter
  SecurityContextHolderAwareRequestFilter
  AnonymousAuthenticationFilter
  SessionManagementFilter
  ExceptionTranslationFilter
  FilterSecurityInterceptor
]

任何有关我在设置中缺少的内容的帮助都将非常有帮助。似乎确实有问题，好像它实际上是在尝试进行身份验证时，将返回401/403。也不例外。减去进行此编译所需的更改，此更改在Spring Boot 1.5.9下有效。

如果我换出@SpringBootTest的模拟mvc注释，这可以工作，但是我不需要这些测试中的数据库，因此我想将其设置为不需要加载它。

发生这种情况是因为Spring正在使用DefaultMethodSecurityExpressionHandler。看到这个：#oauth2 security expressions on method level

要解决此问题，请执行以下操作：

从@EnableGlobalMethodSecurity删除AuthorizationServerConfig
添加以下新的配置类


@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class MethodSecurityConfiguration extends GlobalMethodSecurityConfiguration {
    @Override
    protected MethodSecurityExpressionHandler createExpressionHandler() {
        return new OAuth2MethodSecurityExpressionHandler();
    }
}

对我来说重要的是，我已经在其他配置上已经使用了@EnableGlobalMethodSecurity，所以spring最初忽略了新的配置类

Spring Boot 2 @WebMvcTest和OAuth2＃oauth2.hasScope控制器导致IllegalArgumentException
