java - Spring 启动: StoredCredential (Permission denied)

Question

在ubuntu tomcat上使用spring boot，war包。凭证文件打包在 resources/credentials/gmail 中，但我的邮件服务抛出此错误:

"/var/lib/tomcat8/webapps/ROOT/WEB-INF/classes/credentials/gmail/StoredCredential (Permission denied)"

如何修复此错误？

我使用 apt-get 安装了 tomcat8，我相信它创建了一个 tomcat8 用户和组...这与该文件夹的用户权限有关吗？

使用winscp，导航到凭据文件夹并递归地将(其他)R W X 权限应用于文件夹+。 tomcat8 现在将能够访问/编辑其中的凭据文件。
