您已导入sun.misc.IOUtils，但您可能想要org.apache.commons.io.IOUtils。 Apache IOUtils有the toString() method you want.

要在maven项目中使用它，请包含以下依赖项：

<!-- https://mvnrepository.com/artifact/commons-io/commons-io -->
<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.4</version>
</dependency>

或从项目主页下载jar文件：https://commons.apache.org/proper/commons-io/download_io.cgi

在intellij java。Error中使用Vcard的Qrcode生成器“非静态方法toString（）不能从静态上下文中引用”
