SpringBoot:cannot be resolved to absolute file path because it does not reside in the file system
cannot be resolved to absolute file path because it does not reside in the file system
·
SpringBoot项目里要读取项目中的文件内容,本地运行时正常,打包部署读取文件时报错
cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/xxxx-1.0.0-SNAPSHOT.jar!/BOOT-INF/classes!/data/123.txt
报错代码:
File file = ResourceUtils.getFile("classpath:data/123.txt");
String fileContent = FileUtil.readString(file, StandardCharsets.UTF_8);
报错原因:
打包后,项目将从jar包中,而不是从文件系统中读取文件。
解决方式:
从jar中读取文件流
ClassPathResource resource = new ClassPathResource("data/123.txt");
InputStream inputStream = resource.getInputStream();
String fileContent = IOUtils.toString(inputStream, "utf-8");
