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？

如何在java中发送异步HTTP GET/POST请求而不等待/读取响应？我不想使用任何第三方库..
