如何使用 Spring 加载 UrlResource?
How to load an UrlResource with Spring?
我正在尝试使用 UrlResource
:
加载 HTTP zip 文件
new UrlResource("url:http://www.my-path.to/file.zip")
结果。
Caused by: java.io.FileNotFoundException: URL
[http://www.my-path.to/file.zip] cannot be resolved to absolute file
path because it does not reside in the file system.
使用 Resource
接口加载 HTTP 文件的正确方法是什么?
稍后我想将该资源添加到 Spring 批处理的 ItemReader
。
您需要使用 http:
前缀而不是 url:
来引用带有 UrlResource
的 HTTP 资源。
All URLs have a standardized String
representation, such that appropriate standardized prefixes are used to indicate one URL type from another. This includes file:
for accessing filesystem paths, http:
for accessing resources via the HTTP protocol, ftp:
for accessing resources via FTP, etc.
因此,您将只有 new UrlResource("http://www.my-path.to/file.zip")
.
