apache POI exception in reading xlsx files

问题:

I'm using apache POI for reading xlsx files by adding below dependencies

<dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.8</version>
        </dependency>

<dependency>
            <groupId>org.apache.xmlbeans</groupId>
            <artifactId>xmlbeans</artifactId>
            <version>2.5.0</version>
        </dependency>

I'm getting following exception while running with jetty plugin even if deployed in tomcat.

I removed the xmlbeans dependency as the maven will automatically download poi dependencies , still the same exception.Any help?

回答1:

I used poi with version 3.12. The following dependency is also required:

compile 'org.apache.poi:ooxml-schemas:1.1'

see also http://poi.apache.org/faq.html#faq-N10025

回答2:

I have made it run for these dependencies:

     def poiVersion='3.9'
     compile 'org.apache.poi:poi:'+poiVersion
     compile 'org.apache.poi:poi-ooxml:'+poiVersion
     compile 'org.apache.poi:poi-ooxml-schemas:'+poiVersion

When I try for others it does not work:

3.10 : is not known to maven central

3.11 : fails, with exact the error in this case !!!

Conclusion POI 3.9 works !!!!

回答3:

I tried using poi 3.10, 3.11 and 3.12 beta with Grails and get this error as well.

After downloading and including http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/poi/ooxml-schemas/1.0/ooxml-schemas-1.0.jar the error is gone.

I use 3.7 but have you try adding

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml-schemas</artifactId>
        <version>3.8</version>
    </dependency>
