SpringBoot2 Filter執行兩次問題解決

原因：在請求指定url之外還請求了/favicon.ico 地址 過濾掉問題就解決了

@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
    HttpServletRequest httpServletRequest=(HttpServletRequest) request;
    //favicon 不請求 否則給人執行兩次的錯覺
    if(!httpServletRequest.getRequestURI().contains("favicon.ico")){
        System.out.println(httpServletRequest.getRequestURI());
        chain.doFilter(request,response);
    }

}

}
