java使用POI导入excel并记录一个读取xlsx报错

小蜗牛爱远行2024-03-14 6:05

  • java使用POI导入Excel ，工具类直接上代码

    • 引入Maven

      xml 复制代码 
      <dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.1.2</version>
</dependency>

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>4.1.2</version>
</dependency>

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml-schemas</artifactId>
    <version>4.1.2</version>
</dependency>
<dependency>
    <groupId>org.apache.xmlbeans</groupId>
    <artifactId>xmlbeans</artifactId>
    <version>3.1.0</version>
</dependency>

      • 如果不引入xmlbeans的话解析xlsx文件可能会报错：

        • 我遇到的报错内容为：java.lang.NoSuchMethodError: org.apache.xmlbeans.XmlOptions.setEntityExpansionLimit(I)Lorg/apache/xmlbeans/XmlOptions

    • 导入工具类的代码（代码仅供参考，根据自己需求修改，少的引入自行解决）：
