如何在 Spring Security 3.2 中设置访问控制允许源过滤器

Question

我正在尝试使用Spring Security 3.2设置我的Spring服务器，以便能够执行ajax登录请求。

我关注了Spring Security 3.2视频和几篇帖子，但问题是我得到了

 No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:9000' is therefore not allowed access. 

对于登录请求（见下文）。

我已经创建了一个 CORSFilter 设置，我可以访问系统中未受保护的资源，并将适当的标头添加到响应中。

我的猜测是我没有将CORSFilter添加到安全过滤器链中，否则在链中可能为时已晚。任何想法将不胜感激。

WebApp初始值设定项

public class WebAppInitializer implements WebApplicationInitializer {
    @Override
    public void onStartup(ServletContext servletContext) {
        WebApplicationContext rootContext = createRootContext(servletContext);
        configureSpringMvc(servletContext, rootContext);
        FilterRegistration.Dynamic corsFilter = servletContext.addFilter("corsFilter", CORSFilter.class);
        corsFilter.addMappingForUrlPatterns(null, false, "/*");
    }
    private WebApplicationContext createRootContext(ServletContext servletContext) {
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(SecurityConfig.class, PersistenceConfig.class, CoreConfig.class);
        servletContext.addListener(new ContextLoaderListener(rootContext));
        servletContext.setInitParameter("defaultHtmlEscape", "true");
        return rootContext;
    }

    private void configureSpringMvc(ServletContext servletContext, WebApplicationContext rootContext) {
        AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext();
        mvcContext.register(MVCConfig.class);
        mvcContext.setParent(rootContext);
        ServletRegistration.Dynamic appServlet = servletContext.addServlet(
                "webservice", new DispatcherServlet(mvcContext));
        appServlet.setLoadOnStartup(1);
        Set<String> mappingConflicts = appServlet.addMapping("/api/*");
        if (!mappingConflicts.isEmpty()) {
            for (String s : mappingConflicts) {
                LOG.error("Mapping conflict: " + s);
            }
            throw new IllegalStateException(
                    "'webservice' cannot be mapped to '/'");
        }
    }

SecurityWebAppInitializer：

public class SecurityWebAppInitializer extends AbstractSecurityWebApplicationInitializer {
}

安全配置：

对/api/users 的请求 - 运行良好，并添加了访问控制允许标头。我禁用了csrf和标头，以确保情况并非如此

@EnableWebMvcSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
@Autowired
    protected void registerAuthentication(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .withUser("user").password("password").roles("USER");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .headers().disable()                
            .authorizeRequests()
                    .antMatchers("/api/users/**").permitAll()
                    .anyRequest().authenticated()
                    .and()
            .formLogin()
                .loginPage("/login")
                .permitAll()
                .and()
            .logout()
                .permitAll();
    }

CORFilter：

@Component
public class CORSFilter implements Filter{
    static Logger logger = LoggerFactory.getLogger(CORSFilter.class);
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }
    @Override
    public void doFilter(ServletRequest request, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
        chain.doFilter(request, response);
    }
    public void destroy() {}
}

登录请求：

Request URL:http://localhost:8080/devstage-1.0/login
Request Headers CAUTION: Provisional headers are shown.
Accept:application/json, text/plain, */*
Cache-Control:no-cache
Content-Type:application/x-www-form-urlencoded

Answer 1

配置安全配置时，我缺少的只是AddFilterBefore。

所以最终版本是：

@EnableWebMvcSecurity
@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
  @Autowired
  protected void registerAuthentication(AuthenticationManagerBuilder auth) throws Exception {
    auth.inMemoryAuthentication()
        .withUser("user").password("password").roles("USER");
  }

  @Override
  protected void configure(HttpSecurity http) throws Exception {
      http
          .addFilterBefore(new CORSFilter(), ChannelProcessingFilter.class)
          .formLogin()
              .loginPage("/login")
              .and()
          .authorizeRequests()
              .anyRequest().authenticated();

并从WebAppInitializer中删除 CORSFilter

我知道

现在回答你的问题有点太晚了，但认为可能值得分享。在初始配置中，您已将 Spring 安全性初始值设定项配置元数据注册到根上下文中：

rootContext.register(SecurityConfig.class, PersistenceConfig.class, CoreConfig.class);

当您可以执行此操作时，您不需要这样做，因为它会将安全过滤器链与不需要的 Web 应用程序上下文耦合。相反，您可以通过将 DemissionatingFilterProxy 注册为过滤器，以普通的旧方式添加过滤器链。当然，在添加弹簧安全过滤器链之前，您需要通过添加 Cors 过滤器来维护顺序。

这样，您就可以使用org.apache.catalina.filters软件包附带的库存CorsFilter（只需添加init参数）。无论如何，您也可以坚持自己的配置！:)
