JAVA solves multiple domain name configuration problems

          CROSS_DOMAIN=http://localhost:3000,http://youjiacn.com:3000,http://www.youjiacn.com:3000       

 

        HttpServletResponse httpResponse = (HttpServletResponse)response;

        HttpServletRequest httpRequest = (HttpServletRequest)request;

 

        String[] crossDomains = ConfigUtil.getInstant().getValue(Constant.CROSS_DOMAIN).split(",");

        LOG.info("allow domains is :" + Arrays.asList (crossDomains));

        Set<String> originsDomains = new HashSet<String>(Arrays.asList (crossDomains));

        if(originsDomains.contains(httpRequest.getHeader("Origin"))){

            httpResponse.addHeader("Access-Control-Allow-Origin", httpRequest.getHeader("Origin"));

        }

        httpResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");

        httpResponse.setHeader("Access-Control-Max-Age", "3600");

        httpResponse.setHeader("Access-Control-Allow-Headers", "Origin,X-Requested-With,Content-Type, Accept, Authorization");

        httpResponse.setHeader("Access-Control-Allow-Credentials","true");
