HttpClient和RestTemplate添加代理proxy

@Bean("innerHttpClient")
public CloseableHttpClient innerHttpClient() {
    PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
    // Increase max total connection to 200

    CloseableHttpClient httpClient = HttpClients.custom()
            .setConnectionManager(cm)
            .build();
    return httpClient;
