FileObject localFile = manager.resolveFile(file.getAbsolutePath());
密码包含特殊字符@.
解决方法
如果您的密码包含@,则URL解析器将其视为userinfo – hostname分隔符.然后它会扫描一个主机名,在下一个@上停止,它会分隔实际的主机名.接下来,它检查主机名后面的第一个字符是/,它不是什么,因为它是@.逻辑对我来说没有多大意义,但解释了令人困惑的错误信息
Expecting / to follow the hostname in URI
但无论如何,即使逻辑更好,你的密码或用户名也不能有文字@.您必须将其URL编码为@.
如果您的用户名/密码是可变的,您应该使用UriParser.encode更好地对其进行编码：
public static String encode(String decodedStr)
