この問題は、ネットワークリードデータのタイムアウトであり、以下の方法で解決されます。

• a.タイムアウト時間を長くする
• b.タイムアウト設定を削除する
• c.例外印刷が投げられない

public class HttpClientUtils {
	
	 // Encoding format. Send encoding format unified with UTF-8
    private static final String ENCODING = "UTF-8";
    
    // Set the connection timeout in milliseconds.
    private static final int CONNECT_TIMEOUT = 6000;
    
    // Timeout for requesting data (i.e. response time), in milliseconds.
    private static final int SOCKET_TIMEOUT = 10000;

 /**

         * setConnectionRequestTimeout: Sets the connection request timeout from the connection manager (connection pool).
         * timeout, in milliseconds. This property is a new addition, as the current version is able to share connection pools.
         * setSocketTimeout: the timeout (i.e. response time) for requesting data, in milliseconds. If an interface is accessed and the data cannot be returned within how much time, the call is simply dropped.

        RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(CONNECT_TIMEOUT).setSocketTimeout(SOCKET_TIMEOUT).build();
