读取xlsx文件时出现apache POI异常

Question

我正在使用apache POI 通过添加以下依赖项来读取xlsx文件

<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.8</version>
        </dependency>

<dependency>
            <groupId>org.apache.xmlbeans</groupId>
            <artifactId>xmlbeans</artifactId>
            <version>2.5.0</version>
        </dependency>

即使部署在tomcat中,我也会在使用jetty插件运行时遇到异常.

我删除了xmlbeans依赖,因为maven将自动下载poi依赖项,仍然是同样的异常.任何帮助？

Answer 1

我使用版本3.12的poi.还需要以下依赖项:

compile 'org.apache.poi:ooxml-schemas:1.1'

我使用 3.7 但你尝试添加

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml-schemas</artifactId>
        <version>3.8</version>
    </dependency>
