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);
