java - 在 Spring 3.1 Java Config 中引用 Spring Security 配置

Question

我最近将大部分 Spring 配置切换为使用 Spring 3.1 中基于代码的配置。但是，现在我已经切换了，我的 Spring Security 无法正常工作并在 Tomcat 启动时抛出以下错误:

SEVERE: Exception starting filter springSecurityFilterChain
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named     'springSecurityFilterChain' is defined

我仍然在 XML 文件中有 Spring Security，并且知道它不能在 Spring 中转换为 Java 配置，因为它是一个自定义命名空间，但是，我在我的 Java 配置文件中引用它。我还尝试将 applicationContext-security.xml 配置引用从 Java 配置移动到我的 web.xml 但没有任何运气。

@Configuration
@EnableWebMvc
@Import(ServicesConfig.class)
@ImportResource({ "classpath:applicationContext-security.xml",
"classpath:dataSources.xml" })
@ComponentScan(basePackages = "com.foobar")
public class WebConfig {
   // left out Beans for clarity
}

applicationContext-security.xml:

不要使用 security 命名空间快捷方式并将所有 spring 配置从 XML 迁移到 Java。它将使您的安全性微调变得更加容易。迁移到 3.1 后，我将很快为我们的项目做这件事。您可以找到非常重要的几乎纯 bean 安全 XML 配置示例 here .

编辑:完成配置(上面链接)迁移。故意将所有配置放入一个方法中以使其更短并证明您不需要为每个过滤器单独使用 spring bean。当然，最好将复杂的 init 部分移动到单独的方法中(如有必要，标记为 @Bean)。您可以在上面链接的 X509AnnotationTest.Config 中找到工作示例。

@Bean
public FilterChainProxy springSecurityFilterChain() throws Exception {
    // AuthenticationEntryPoint
    BasicAuthenticationEntryPoint entryPoint = new BasicAuthenticationEntryPoint();
    entryPoint.setRealmName("AppName Realm");
    // accessDecisionManager
    List<AccessDecisionVoter> voters = Arrays.<AccessDecisionVoter>asList(new RoleVoter(), new WebExpressionVoter());
    AccessDecisionManager accessDecisionManager = new AffirmativeBased(voters);
    // SecurityExpressionHandler
    SecurityExpressionHandler<FilterInvocation> securityExpressionHandler = new DefaultWebSecurityExpressionHandler();
    // AuthenticationUserDetailsService
    UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken> authenticationUserDetailsService = new UserDetailsByNameServiceWrapper<PreAuthenticatedAuthenticationToken>(authUserDetailService);
    authenticationUserDetailsService.afterPropertiesSet();
    // PreAuthenticatedAuthenticationProvider
    PreAuthenticatedAuthenticationProvider preAuthenticatedAuthenticationProvider = new PreAuthenticatedAuthenticationProvider();
    preAuthenticatedAuthenticationProvider.setPreAuthenticatedUserDetailsService(authenticationUserDetailsService);
    preAuthenticatedAuthenticationProvider.afterPropertiesSet();
    // AuthenticationManager
    List<AuthenticationProvider> providers = Arrays.<AuthenticationProvider>asList(preAuthenticatedAuthenticationProvider);
    AuthenticationManager authenticationManager = new ProviderManager(providers);
    // HttpSessionSecurityContextRepository
    HttpSessionSecurityContextRepository httpSessionSecurityContextRepository = new HttpSessionSecurityContextRepository();
    // SessionRegistry
    SessionRegistry sessionRegistry = new SessionRegistryImpl();
    // ConcurrentSessionControlStrategy
    ConcurrentSessionControlStrategy concurrentSessionControlStrategy = new ConcurrentSessionControlStrategy(sessionRegistry);

    // ConcurrentSessionFilter
    ConcurrentSessionFilter concurrentSessionFilter = new ConcurrentSessionFilter(sessionRegistry);
    concurrentSessionFilter.afterPropertiesSet();
    // SecurityContextPersistenceFilter
    SecurityContextPersistenceFilter securityContextPersistenceFilter = new SecurityContextPersistenceFilter(httpSessionSecurityContextRepository);
    // X509AuthenticationFilter
    X509AuthenticationFilter x509AuthenticationFilter = new X509AuthenticationFilter();
    x509AuthenticationFilter.setAuthenticationManager(authenticationManager);
    x509AuthenticationFilter.afterPropertiesSet();
    // RequestCacheAwareFilter
    RequestCacheAwareFilter requestCacheAwareFilter = new RequestCacheAwareFilter();
    // SecurityContextHolderAwareRequestFilter
    SecurityContextHolderAwareRequestFilter securityContextHolderAwareRequestFilter = new SecurityContextHolderAwareRequestFilter();
    // SessionManagementFilter
    SessionManagementFilter sessionManagementFilter = new SessionManagementFilter(httpSessionSecurityContextRepository, concurrentSessionControlStrategy);
    // ExceptionTranslationFilter
    ExceptionTranslationFilter exceptionTranslationFilter = new ExceptionTranslationFilter(entryPoint);
    exceptionTranslationFilter.setAccessDeniedHandler(new AccessDeniedHandlerImpl());
    exceptionTranslationFilter.afterPropertiesSet();
    // FilterSecurityInterceptor
    FilterSecurityInterceptor filterSecurityInterceptor = new FilterSecurityInterceptor();
    filterSecurityInterceptor.setAuthenticationManager(authenticationManager);
    filterSecurityInterceptor.setAccessDecisionManager(accessDecisionManager);
    LinkedHashMap<RequestMatcher, Collection<ConfigAttribute>> map = new LinkedHashMap<RequestMatcher, Collection<ConfigAttribute>>();
    map.put(new AntPathRequestMatcher("/**"), Arrays.<ConfigAttribute>asList(new SecurityConfig("isAuthenticated()")));
    ExpressionBasedFilterInvocationSecurityMetadataSource ms = new ExpressionBasedFilterInvocationSecurityMetadataSource(map, securityExpressionHandler);
    filterSecurityInterceptor.setSecurityMetadataSource(ms);
    filterSecurityInterceptor.afterPropertiesSet();
    // SecurityFilterChain
    SecurityFilterChain chain = new DefaultSecurityFilterChain(new AntPathRequestMatcher("/**"),
            concurrentSessionFilter,
            securityContextPersistenceFilter,
            x509AuthenticationFilter,
            requestCacheAwareFilter,
            securityContextHolderAwareRequestFilter,
            sessionManagementFilter,
            exceptionTranslationFilter,
            filterSecurityInterceptor);
    return new FilterChainProxy(chain);
