Apache poi excel writer 在 ide 中工作，但在 fat jar 中不起作用？java.io.IOException：您的InputStream既不是OLE2流，也不是OOXML str

Question

该代码在 IDE 中运行得很好，但在普通.jar或fat .jar? 否则该程序运行得很好。也non-fat .jar不起作用。

错误是：

Jun 08, 2021 11:43:14 AM DataManagers.ExcelWriter$WriterThread run
SEVERE: null
java.io.IOException: Your InputStream was neither an OLE2 stream, nor an OOXML stream or you haven't provide the poi-ooxml*.jar in the classpath/modulepath - FileMagic: OOXML, having providers: [org.apache.poi.hssf.usermodel.HSSFWorkbookFactory@405294c8]

并且这个错误重复3次。

一些代码示例如下：

FileInputStream f = new FileInputStream(file);
wb = WorkbookFactory.create(f);
s = wb.getSheet("Sheet1");
initialiseExcel();
f.close();
FileOutputStream fOut = new FileOutputStream(file);
initialiseExcel();
Row row = s.createRow(0);
Cell cell = row.createCell(1);
cell.setCellValue("Pvm");    wb.write(fOut);
fOut.close();
...

我已经搜索了修复程序，但似乎每个人都说 fat jar 修复了它，但我正在运行 fat jar，问题仍然出现，我真的不知道该怎么办？

非常感谢任何愿意提供帮助的人。

您可以使用dependency-plugin在打包阶段之前在单独的目录中生成所有依赖项，然后通过以下方式将其包含在清单的类路径中maven-jar-plugin：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-dependencies</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/lib</outputDirectory>
                <overWriteReleases>false</overWriteReleases>
                <overWriteSnapshots>false</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
            </configuration>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <classpathPrefix>lib/</classpathPrefix>
                <mainClass>theMainClass_ChangeMe_withPackage</mainClass>
            </manifest>
        </archive>
    </configuration>
</plugin>

或者使用${project.build.directory}/classes/lib作为输出目录将所有 jar 文件集成到主 jar 中，但随后您将需要添加自定义类加载代码来加载 jar。我希望这会有所帮助，因为maven-assembly插件不适用于此 scanerio。
