Spring Boot提供了多種方式來解析文件數據,以下是其中一些常用的方法:
import org.springframework.core.io.Resource;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.FileSystemResource;
public class FileParser {
public void parseFile(String filePath) {
try {
Resource resource = new ClassPathResource(filePath);
// 或者使用FileSystemResource
// Resource resource = new FileSystemResource(filePath);
// 讀取文件內容
InputStream inputStream = resource.getInputStream();
// 對文件數據進行解析
} catch (IOException e) {
e.printStackTrace();
}
}
}
import org.springframework.web.multipart.MultipartFile;
public class FileUploadController {
public void uploadFile(MultipartFile file) {
try {
// 獲取上傳文件的字節流
InputStream inputStream = file.getInputStream();
// 對文件數據進行解析
} catch (IOException e) {
e.printStackTrace();
}
}
}
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class FileUploadController {
public void uploadFile(HttpServletRequest request) {
try {
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List<FileItem> items = upload.parseRequest(request);
for (FileItem item : items) {
if (!item.isFormField()) {
// 獲取上傳文件的字節流
InputStream inputStream = item.getInputStream();
// 對文件數據進行解析
}
}
} catch (FileUploadException | IOException e) {
e.printStackTrace();
}
}
}
這些方法都可以幫助您解析文件數據,具體選擇哪種方法取決于您的需求和項目環境。
