Spring Rest模板Http客户端错误异常

Question

RestTemplate Works fine with internal url but fails with public url.

@Bean
public RestTemplate restTemplate() {
    RestTemplate restTemplate = new RestTemplate();
    setTimeout(restTemplate , 40000 , 40000);
    return restTemplate;
}

private void setTimeout(RestTemplate restTemplate, int readTimeOut , int connectionTimeOut) {
    restTemplate.setRequestFactory(new SimpleClientHttpRequestFactory());
    SimpleClientHttpRequestFactory rf = (SimpleClientHttpRequestFactory) restTemplate.getRequestFactory();
    rf.setReadTimeout(readTimeOut);
    rf.setConnectTimeout(connectionTimeOut);
}

Is there any way to fix this issue ?

it throws Httpclientexception by restteamplate when accessing public url.
