问题与CORS有关，您应该添加以下内容：

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain chain)        throws IOException, ServletException {    HttpServletRequest request = (HttpServletRequest) servletRequest;    System.out.println("CORSFilter HTTP Request: " + request.getMethod());    // Authorize (allow) all domains to consume the content    ((HttpServletResponse) servletResponse).addHeader("Access-Control-Allow-Origin", "*");    ((HttpServletResponse) servletResponse).addHeader("Access-Control-Allow-Methods","GET, OPTIONS, HEAD, PUT, POST");    HttpServletResponse resp = (HttpServletResponse) servletResponse;    // For HTTP OPTIONS verb/method reply with ACCEPTED status pre -- per CORS handshake    if (request.getMethod().equals("OPTIONS")) {        resp.setStatus(HttpServletResponse.SC_ACCEPTED);        return;    }    // pass the request along the filter chain    chain.doFilter(request, servletResponse);}
