通過網上搜索，找到了解決方法：
1、設置多個可跨域域名數組
2、通過request的getHeader(“Origin”)獲取origin
3、請求域名屬于可跨域域名數組，將所取的orgin值設給Access-Control-Allow-Origin
// 跨域域名設置 public static final String[] ALLOW_DOMAIN = { "http://localhost:8000", "http://192.168.0.100" };
HttpServletRequest req = (HttpServletRequest) request; HttpServletResponse res = (HttpServletResponse) response; String originHeader = req.getHeader("Origin"); if (Arrays.asList(Constants.ALLOW_DOMAIN).contains(originHeader)) { res.setHeader("Access-Control-Allow-Origin", originHeader); res.setHeader("Allow", "*"); res.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, DELETE, OPTIONS"); res.setHeader( "Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Referer, User-Agent, Authorization, X-Auth-Token"); res.setHeader("Access-Control-Max-Age", "3600"); // 接收跨域的cookie res.setHeader("Access-Control-Allow-Credentials", "true"); if ("IE".equals(req.getParameter("type"))) { ((HttpServletResponse) response).setHeader( "XDomainRequestAllowed", "1"); } if (req.getMethod().toLowerCase().equals("options")) { res.setHeader("Content-type", "text/html"); res.getWriter().write("options OK"); return; } }
