java - Apache POI 解析错误

Question

我知道这个问题经常被问到，但找不到合适的解决方案。 与

一起工作时

XWPFDocument xdoc = new XWPFDocument(srcFile);

或

XSSFWorkbook workbook = new XSSFWorkbook(srcFile);

我总是遇到以下错误:

Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.apache.poi.util.POILogger.log(ILjava/lang/Object;)V from class org.apache.poi.openxml4j.opc.PackageRelationshipCollection

人们建议打开 PackageRelationshipCollection 并重试。但这并没有太大帮助。

我还加载了 jar :

<dependency>
   <groupId>org.apache.poi</groupId>
   <artifactId>poi</artifactId>
   <version>3.13</version>
   <type>jar</type>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-scratchpad</artifactId>
    <version>3.13</version>
    <type>jar</type>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.12</version>
    <type>jar</type>
</dependency>
 <dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml-schemas</artifactId>
    <version>3.11</version>
    <type>jar</type>
</dependency>

来自Apache POI FAQ :

Can I mix POI jars from different versions?

No. This is not supported.

All POI jars in use must come from the same version. A combination such as poi-3.11.jar and poi-ooxml-3.9.jar is not supported, and will fail to work in unpredictable ways.

您的 pom 依赖于 3.11、3.12 和 3.13 的 Apache POI jar，即 the FAQ explained isn't supported

你需要将所有这些更改为 3.13，然后它会工作

我建议像这样:

<properties>
  <poi.version>3.13</poi.version>
</properties>
<dependencies>
  <dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>${poi.version}</version>
  </dependency>
  <dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-scratchpad</artifactId>
    <version>${poi.version}</version>
  </dependency>
  <dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>${poi.version}</version>
  </dependency>
  <!-- etc as needed -->

这样，您可以确保所有 POI jar 都来自同一版本!
