我试图使用Apache POI将保护添加到MS Excel文件中，当我进行一些测试时它工作正常，但是当我在Weblogic Server 12中证明运行时的功能时，它失败了。这是我的代码：
public static void parseFileToSecureFile(String fullFileName, String password) throws MyException{
POIFSFileSystem fs = new POIFSFileSystem();
EncryptionInfo info =
new EncryptionInfo(EncryptionMode.agile, CipherAlgorithm.aes256, HashAlgorithm.sha512, -1, -1, null);
Encryptor enc = info.getEncryptor();
enc.confirmPassword(password);
OPCPackage opc = null;
OutputStream os = null;
FileOutputStream fos = null;
try {
opc = OPCPackage.open(new File(fullFileName), PackageAccess.READ_WRITE);
os = enc.getDataStream(fs);
opc.save(os);
fos = new FileOutputStream(fullFileName);
fs.writeFilesystem(fos);
} catch (Exception e) {
logger.error("error: "+e.getMessage(), e);
throw new MyException("An Error");
}finally {
fs.close();
fos.close();
}
}
public static void main(String[] args){
System.out.println("Inicia");
try {
parseFileToSecureFile("/my_path/my_file.xlsx", "11");
} catch (MyException e) {
e.printStackTrace();
}
System.out.println("Finaliza");
}
正如我告诉您的，如果我从我的"main 方法"按原样运行我的代码，它可以工作，但是如果我在运行时从 Web 应用程序调用该方法，我有下一个异常：
org.apache.poi.EncryptedDocumentException: java.lang.ClassCastException: org.apache.poi.poifs.crypt.agile.AgileEncryptionInfoBuilder cannot be cast to org.apache.poi.poifs.crypt.EncryptionInfoBuilder

感谢您的帮助
如果其他人有同样的问题，这是我必须做的更改：
- 将我的 POI 版本从 v3.15 更新到 v4.0.1
- 添加共享压缩 v1.18
此外，如果您必须读取加密文件，您将需要：
- XMLbean-3.0.2
- 共享资源集合4-4.1
Weblogic Server 有自己的 xmlbeans 版本，您将遇到依赖冲突，因此，您需要将容器描述符标记中的下一个标记添加到 weblogic.xml 文件中：
<prefer-web-inf-classes>false</prefer-web-inf-classes>
您还需要将下一个标签添加到 weblogic-application.xml 文件中：
<prefer-application-packages>
<package-name>org.apache.xmlbeans.*</package-name>
<package-name>repackage.*</package-name>
<package-name>schemaorg_apache_xmlbeans.system.*</package-name>
</prefer-application-packages>
