java解决dns解析超时

System.setProperty("networkaddress.cache.ttl" , "5");
System.setProperty("sun.net.inetaddr.ttl" , "5");

InetAddress[] dnsServers = new InetAddress[]{
    InetAddress.getByName("8.8.8.8"),
    InetAddress.getByName("8.8.4.4")
};
DnsResolver.setCustomDNS(dnsServers);

ExecutorService executor = Executors.newFixedThreadPool(10);
Future<InetAddress> future = executor.submit(() -> {
    return InetAddress.getByName("example.com");
});
try {
    InetAddress address = future.get(5, TimeUnit.SECONDS);
    // 处理解析结果
} catch (TimeoutException e) {
    // 解析超时处理
} catch (Exception e) {
    // 其他异常处理
} finally {
    executor.shutdown();
}
