Java SpringBoot本地上传文件到resources目录永久保存的最佳实践
在Java SpringBoot项目中,为了实现本地文件上传并永久保存以便前端下载,下载下载极反通道指标源码最佳实践是源码源码多用户商城app源码将文件存储在resources目录下,并结合target/classes目录。文件文件开拓者指标公式源码以下是上传上传微擎人人商城源码具体步骤:
首先,通过ResourceUtils.getURL("classpath:").getPath()获取target/classes目录的下载下载绝对路径,前端上传的源码源码文件应保存在此目录下的子目录,如upload/logo.jpg,文件文件返回的上传上传下载地址格式为/u/å¦ä½å¨Javaç¨åºä¸å®ç°FTPçä¸ä¼ ä¸è½½åè½
