java - 无法在 linux 服务器上使用 spring boot 访问公共资源（img，file ...）
问题描述
我正在尝试将SpringBoot应用程序作为 jar 从Linux 机器启动，并且我无法在 linux 服务器上使用 spring boot 访问公共资源（img，file ...），它仅在 IDE 上的 Windows 中运行良好，但在 linux 机器上部署后或即使我尝试在 Windows 中使用java -jar 启动它，我也面临着这个问题。
上传/加载文件仅在我使用 IDE 运行时才有效
@Configuration
public class MvcConfig implements WebMvcConfigurer {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
exposeDirectory("docs", registry);
}
private void exposeDirectory(String dirName, ResourceHandlerRegistry registry) {
Path uploadDir = Paths.get(dirName);
String uploadPath = uploadDir.toFile().getAbsolutePath();
if (dirName.startsWith("../")) dirName = dirName.replace("../", "");
registry
.addResourceHandler("/" + dirName + "/**")
.addResourceLocations("file:/"+ uploadPath + "/");
}
}
上传文件的方法：
private Doc getDoc (MultipartFile file, FileType type, String uploadDir) throws IOException {
Doc document = new Doc();
Path uploadPath = Paths.get(uploadDir);
if (!Files.exists(uploadPath)) {
Files.createDirectories(uploadPath);
}
String fileName = StringUtils.cleanPath(Objects.requireNonNull(file.getOriginalFilename()));
try (InputStream inputStream = file.getInputStream()) {
Path filePath = uploadPath.resolve(fileName);
Files.copy(inputStream, filePath, StandardCopyOption.REPLACE_EXISTING);
} catch (IOException ioe) {
throw new IOException("Could not save image file: " + fileName, ioe);
}
document.setFileName(fileName);
document.setFileType(type);
document.setFilePath("/" + uploadDir + "/" + fileName);
return document;
}
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
