Question

我正在使用spring oauth2和angular进行此测试。 Spring Boot应用程序在端口8081上，而Angular在4200上，我已经在Spring上为端口4200设置了CORS。当我单击Gmail按钮时，Spring没有任何例外，仅在chrome上，没有No'Access-Control-Allow-Origin'错误。

Java代码：

@Autowired
    private OAuth2ClientContext oauthClientContext;

    @Value("${cross-origin-url}")
    private String crossOriginUrl;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // TODO Auto-generated method stub
        http.cors()
            .and().csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
            .and()
            .antMatcher("/**").authorizeRequests()
                .antMatchers("/login**","/","/test","/login/gmail").permitAll()
                .anyRequest().fullyAuthenticated()
            .and()
            .addFilterBefore(oauthGmailFilter(), BasicAuthenticationFilter.class)
            ;
    }

    @Bean
    public CorsConfigurationSource corsConfigurationSource() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration cors = new CorsConfiguration();
        cors.addAllowedOrigin(crossOriginUrl);
        source.registerCorsConfiguration("/**", cors.applyPermitDefaultValues());
        return source;
    }

    @Bean
    public Filter oauthGmailFilter() {
        OAuth2ClientAuthenticationProcessingFilter gmailFilter = new OAuth2ClientAuthenticationProcessingFilter("/login/gmail");
        OAuth2RestTemplate gmailTemplate = new OAuth2RestTemplate(gmail(),oauthClientContext);
        gmailFilter.setRestTemplate(gmailTemplate);
        UserInfoTokenServices tokenService = new UserInfoTokenServices(gmailResource().getUserInfoUri(),gmail().getClientId());
        tokenService.setRestTemplate(gmailTemplate);
        gmailFilter.setTokenServices(tokenService);
        return gmailFilter;
    }

    @Bean
    @ConfigurationProperties("gmail.client")
    public AuthorizationCodeResourceDetails gmail() {
        return new AuthorizationCodeResourceDetails();
    }

    @Bean
    @ConfigurationProperties("gmail.resource")
    public ResourceServerProperties gmailResource() {
        return new ResourceServerProperties();
    }

    @Bean
    public FilterRegistrationBean<OAuth2ClientContextFilter> oauth2ClientFilterRegistration(OAuth2ClientContextFilter filter) {
        FilterRegistrationBean<OAuth2ClientContextFilter> registration = new FilterRegistrationBean<OAuth2ClientContextFilter>();
        registration.setFilter(filter);
        registration.setOrder(-100);
        return registration;
    }
