啓動應用程序時無法創建bean

我在創建bean時出現了一些問題，導致出錯。有人可以幫助我嗎。我將從sftp資源中檢索這些文件，並將使用spring任務計劃程序作業讀取這些文件。啓動應用程序時無法創建bean

應用-config.xml中

你能不能嘗試更換'<屬性名=「用戶名」值=「$ {sftp.username}」/>'用''。我認爲在DefaultSftpSessionFactory中字段名稱是'user'而不是'username' – barunsthakur

請訪問DefaultSftpSessionFactory

它具有如下：

setUser 

    public void setUser(String user) 

    The remote user to use. This is a mandatory property. 

    Parameters: 
     user - The user. 
    See Also: 
     JSch.getSession(String, String, int)
