我已经集成了带角度应用程序的按键斗篷。基本上，前端和后端都在不同的服务器上。后端应用程序在Tomcat
8上运行。前端应用程序在JBoss欢迎内容文件夹上运行。

角度配置

angular.element(document).ready(function ($http) {
    var keycloakAuth = new Keycloak('keycloak.json');
    auth.loggedIn = false;
    keycloakAuth.init({ onLoad: 'login-required' }).success(function () {
        keycloakAuth.loadUserInfo().success(function (userInfo) {
            console.log(userInfo);  
        });
        auth.loggedIn = true;
        auth.authz = keycloakAuth;
        auth.logoutUrl = keycloakAuth.authServerUrl + "/realms/app1/protocol/openid-connect/logout?redirect_uri=http://35.154.214.8/hrms-keycloak/index.html";
        module.factory('Auth', function() {
            return auth;
        });
        angular.bootstrap(document, ["themesApp"]);
    }).error(function () {
            window.location.reload();
        });

});
module.factory('authInterceptor', function($q, Auth) {
    return {
        request: function (config) {
            var deferred = $q.defer();
            if (Auth.authz.token) {
                Auth.authz.updateToken(5).success(function() {
                    config.headers = config.headers || {};
                    config.headers.Authorization = 'Bearer ' + Auth.authz.token;
                    deferred.resolve(config);
                }).error(function() {
                        deferred.reject('Failed to refresh token');
                    });
            }
            return deferred.promise;
        }
    };
});
module.config(["$httpProvider", function ($httpProvider)  {
    $httpProvider.interceptors.push('authInterceptor');
}]);

请求标题

Web控制台错误。

XMLHttpRequest cannot load http://35.154.214.8:8080/company/loadCurrencyList. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://35.154.214.8' is therefore not allowed access.

后端的Cors筛选器

@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", "*");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "*");
        chain.doFilter(request, response);
    }

    public void destroy() {
    }
}
