3、在接收到OPTIONS请求时候，需要返回状态码为202，并且设置响应头部（根据需求变更）

HttpServletResponse httpResponse = response;
         httpResponse.setCharacterEncoding("UTF-8");
         httpResponse.setContentType("application/json; charset=utf-8");
         httpResponse.setHeader("Access-Control-Allow-Origin","*");
         httpResponse.setHeader("Access-Control-Allow-Credentials", "true");
         httpResponse.setHeader("Access-Control-Allow-Methods", "POST,GET,OPTIONS,DELETE,PATCH,PUT");
         httpResponse.setHeader("Access-Control-Max-Age", "3600");
         httpResponse.setHeader("Access-Control-Allow-Headers", "Origin,X-Requested-With,x-requested-with,X-Custom-Header," +
                  "Content-Type,Accept,Authorization");
         String method = request.getMethod();
         if ("OPTIONS".equalsIgnoreCase(method)){
            logger.info("OPTIONS请求");
            httpResponse.setStatus(HttpServletResponse.SC_ACCEPTED);
         }复制代码
