JAVA POI 读取2007 EXCEL时 XSSFWorkbook(fis);出错

原因
poi-ooxml的版本3.16和poi的版本3.9不一致

        <dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi</artifactId>            <version>3.9</version>        </dependency>        <dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi-ooxml</artifactId>            <version>3.16</version>        </dependency>

改成如下就OK了

<dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi</artifactId>            <version>3.9</version>        </dependency>        <dependency>            <groupId>org.apache.poi</groupId>            <artifactId>poi-ooxml</artifactId>            <version>3.9</version>        </dependency>
