Java——Read/convert an InputStream to a String

获取 InputStream 并将其转换为String的简单方法。

添加commons-io-2.4.jar

import java.io.IOException;
import java.io.InputStream;
import org.apache.commons.io.IOUtils;

public class StringFromFile {

    public static void main(String[] args) throws IOException {
        InputStream inputStream = StringFromFile.class.getResourceAsStream("2.txt");
        String myString = IOUtils.toString(inputStream, "UTF-8");

        System.out.println(myString);

    }

}
