spring proxy basic-authentication resttemplate

Add proxy information and basic auth to the resttemplate using httpClient

My development environment is behind a proxy so i need to set the proxy information to the rest template, that's all good when i use a HttpComponentsClientHttpRequestFactory and set the proxy setting in the httpClient and set it in the template.

But now i have a rest service that needs basic auth. And to set the basic auth credentials, i need to set them in the httpClient on the rest template. But i see that the getparams method in the httpClient is depricated, so i can't just update the existing client in the template, and if i create a new httpclient object, i will overwrite the proxy info that were set during the application bootstrapping.

So is there some way that i could extract the httpClient from the rest template and update it? Or is there any other way to tackle this?

Thanks.

Solution

Configure the httpClient as follows:

HttpHost target = new HttpHost("hostname", 80, "http");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
        new AuthScope(target.getHostName(), target.getPort()),
        new UsernamePasswordCredentials("user", "passwd"));

HttpHost proxy = new HttpHost("proxy", 12345);
CloseableHttpClient httpclient = HttpClients.custom()
        .setProxy(proxy)
        .setDefaultCredentialsProvider(credsProvider).build();

HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpclient);

RestTemplate restTemplate = new RestTemplate(requestFactory);
