我尝试将引用库中需要的所有jar都包括在内。 这个论坛上有类似的问题,我经历了所有问题,但无法解决。
我的代码段:
Workbook workbook = new XSSFWorkbook();
CreationHelper createHelper = workbook.getCreationHelper();
Sheet sheet = workbook.createSheet("Gene");
Font headerFont = workbook.createFont();
我遇到以下错误:

答案 0 :(得分:1)
您需要使用xmlbeans-3.0.1
而不是xmlbeans-5.1.3
。
从错误开始,这是:
Caused by: java.lang.NoSuchMethodError: org.openxmlformats.schemas.spreadsheetml.x2006.main.impl.CTWorksheetImpl.generatedSetterHelperImpl(Lorg/apache/xmlbeans/XmlObject;Ljavax/xml/namespace/QName;IS)Lorg/apache/xmlbeans/XmlObject;
我在Maven中央存储库中搜索了包含类CTWorksheetImpl
的jar:
https://search.maven.org/search?q=fc:org.openxmlformats.schemas.spreadsheetml.x2006.main.impl.CTWorksheetImpl
答案是poi-ooxml-schemas
,您已经有了,并且答案与poi
相同。好像还可以。然后我认为它必须是方法本身。这些参数来自org.apache.xmlbeans
软件包,因此xmlbeans
版本可能是错误的。
如何找到合适的版本?
您可能需要尝试Maven进行依赖项管理,而不是手动收集jar文件。在Maven项目中,仅需说poi-ooxml
就足够了。这将自动以正确的版本递归引入所有依赖项。
这是示例Maven pom.xml
文件,您可以使用您的项目:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.example</groupId>
<artifactId>poi-example</artifactId>
<version>0.0.1-SNAPSHOT</version>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>4.0.0</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
</project>
即使您不想(或不能)在项目中使用Maven,也可以像我一样,至少可以做一个单独的项目来查找依赖项。
