Apache POI 和 Weblogic JAR 冲突 - POI 5 和 xmlbeans

Question

我目前正在尝试使用 apache POI 在 java 中制作 excel 文件，确切地说是 SXSSF。但是，在运行它时，出现以下错误：

Caused By: java.lang.ExceptionInInitializerError
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName(Class.java:348)

现在，我知道出现了与此类似的问题，通常的解决方法是更改​​ weblogic.xml，然后

<prefer-web-inf-classes>false</prefer-web-inf-classes>

<wls:container-descriptor>
        <wls:prefer-application-packages>
            <wls:package-name>org.apache.commons.collections4.*</wls:package-name>
            <wls:package-name>org.apache.commons.compress.*</wls:package-name>
            <wls:package-name>org.apache.poi.*</wls:package-name>
            <wls:package-name>org.apache.xmlbeans.*</wls:package-name>
            <wls:package-name>org.apache.xmlbeans.XmlOptions</wls:package-name>
            <wls:package-name>org.openxmlformats.*</wls:package-name>
            <wls:package-name>schemaorg_apache_xmlbeans.*</wls:package-name>
        </wls:prefer-application-packages>
        <wls:prefer-application-resources>
            <wls:resource-name>schemaorg_apache_xmlbeans/system/sXMLCONFIG/TypeSystemHolder.class</wls:resource-name>
            <wls:resource-name>schemaorg_apache_xmlbeans/system/sXMLLANG/TypeSystemHolder.class</wls:resource-name>
            <wls:resource-name>schemaorg_apache_xmlbeans/system/sXMLSCHEMA/TypeSystemHolder.class</wls:resource-name>
            <wls:resource-name>schemaorg_apache_xmlbeans/system/sXMLTOOLS/TypeSystemHolder.class</wls:resource-name>
        </wls:prefer-application-resources>
    </wls:container-descriptor>
 

但是，出现的问题是将 prefer-web-inf-classes 设置为 false 会破坏应用程序的其余部分。所以我的问题是，在我创建 excel 的文件中是否有一种方法可以指定我希望它是从 apache xmlbeans 而不是 weblogic xmlbeans 构建的？我在想类似 Classloader/Urlloader 的东西，但我还不能使它正常工作，但我可能实施错了。

最后，我将包括我的 pom.xml 文件

Answer 1

更具体地说，在我的例子中，我已将以下代码添加到 weblogic-application.xml 以修复异常 - java.lang.ClassCastException: org.apache.xmlbeans.impl.schema.SchemaTypeSystemImpl cannot be cast to org.apache。 xmlbeans.SchemaTypeLoader

<weblogic-application>
    <prefer-application-packages>
        <package-name>org.apache.*</package-name>
        <package-name>schemaorg_apache_xmlbeans.*</package-name>
    </prefer-application-packages>
    <prefer-application-resources>
        <resource-name>schemaorg_apache_xmlbeans/*</resource-name>
    </prefer-application-resources>
</weblogic-application>
