Apache POI解析错误

Question

我知道这个问题经常被问到，但是找不到合适的解决方案。使用时

XWPFDocument xdoc = new XWPFDocument(srcFile);

或

XSSFWorkbook workbook = new XSSFWorkbook(srcFile);

我总是以下面的错误结束：

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。但这并没有多大帮助。

还有，我已经把罐子装好了：

<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>

Answer 1

从Apache POI FAQ

是否可以混合不同版本的POI jars？

不是的。这不受支持。

使用中的所有POI jars必须来自同一版本。不支持poi-3.11.jar和poi-ooxml-3.9.jar这样的组合，并且将无法以不可预测的方式工作。

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

您需要将所有这些都更改为3.13，然后它就可以工作了

我建议这样做：

<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，您就可以确保所有POI jars都来自同一版本！
