我正在从 sftp 服务器读取文件并使用 Spring Batch Framework 将该文件加载到数据库中，下面是我的代码，但我收到错误
代码:
<bean id="cvsFileItemReaderMeta" class="org.springframework.batch.item.file.FlatFileItemReader">
<!-- Read a csv file -->
<property name="resource" value= "ftp://scmuser:scmuser%40123@172.18.228.32:22/home/scmuser/CSV/Meta.csv" />
错误:

最佳答案
Caused by: java.lang.IllegalStateException: Input resource must exist (reader is in 'strict' mode): URL [ftp://username:password@hostname.com:22/home/scmuser/CSV/Meta.csv]
显然该资源不存在。您要么必须在尝试打开资源之前确保该资源存在，要么使用 FlatFileItemReader#setStrict 取消设置阅读器的严格模式。并传递 false
In strict mode the reader will throw an exception on AbstractItemCountingItemStreamItemReader.open(org.springframework.batch.item.ExecutionContext) if the input resource does not exist.
