Apache Commons VFS - 无法解析文件

Posted 2021-04-06

VFS方法无法处理在${jboss.server.temp.dir}/local/outgoing中配置的这个URI jboss-beans.xml，它由JBoss解析为"C:\Download\jboss-eap-5.1.1\server\default\tmp/local/outgoing"。当我尝试解析URI并获取文件时，它会抛出异常。任何想法可能是什么问题？

Exception

17:35:25,024 ERROR [VfsSynchronizerConfImpl] File FromOutgoing cannot be resolved, FileSystemException:
org.apache.commons.vfs2.FileSystemException: Could not find file with URI "C:Downloadjboss-eap-5.1.1serverdefault	mp/local/outgoing" because it is a relative path, and no base URI was provided.

    at org.apache.commons.vfs2.impl.DefaultFileSystemManager.resolveFile(DefaultFileSystemManager.java:605)

DefaultFileSystemManager.class methods

public FileObject resolveFile(final String uri) throws FileSystemException
  -- this method calls the method below

public FileObject resolveFile(final FileObject baseFile, final String uri,
        final FileSystemOptions fileSystemOptions)
        throws FileSystemException
  -- this method cannot process the string and throws
     throw new FileSystemException("vfs.impl/find-rel-file.error", uri);

答案

我认为它需要文件：scheme，因为错误说它被认为是相对的。

另一答案

对于面临这个问题的其他人：我通过替换摆脱了这个错误

FileSystemManager fsManager = VFS.getManager();

同

StandardFileSystemManager fsManager = new StandardFileSystemManager();
fsManager.init();

这允许我多次使用文件系统管理器，而不会在问题中描述错误。当你完成它时，不要忘记关闭你fsManager：

fsManager.close();
