示例1: getInputStream
import org.apache.commons.io.input.ProxyInputStream; //导入依赖的package包/类
/**
* Returns an input stream for the requested file.
*
* After completing the read the stream must be closed. It is not necessary to call the {@link #release()}
* method after reading from the input stream.
*
* Example usage:
*
* DataStore dataStore = new DataStore(...);
* try (InputStream is = dataStore.getInputStream()) {
* // read from is
* } catch (IOException e) {
* ...
* }
*
* @return
* @throws IOException
