spring启动：CORS问题

尽管Spring安全性提供了一种在httpconfigurer中配置CORS的方法，但是有一种更加干净的方法可以将CORS过滤器添加到应用程序中，

@Component@Order(Ordered.HIGHEST_PRECEDENCE)public class MyCORSFilter implements Filter {@Overridepublic void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {    HttpServletRequest request = (HttpServletRequest) req;    HttpServletResponse response = (HttpServletResponse) res;    response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));    response.setHeader("Access-Control-Allow-Credentials", "true");    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");    response.setHeader("Access-Control-Max-Age", "3600");    response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");    chain.doFilter(req, res);}@Overridepublic void init(FilterConfig filterConfig) {}@Overridepublic void destroy() {}}

对过滤器进行最高优先级排序可确保MyCORSFilter实现
