在我的服務類我使用：

import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.text.SimpleDateFormat;

import java.util.Map;
import org.apache.commons.io.IOUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.util.Base64Utils;
import org.springframework.web.multipart.MultipartFile;
import com.a2bnext.dao.A571DAO;
import com.a2bnext.dao.ReceivingNumberDAO;
import com.a2bnext.entity.A571;
import com.a2bnext.entity.ReceivingNumber;
@Service
public class FileUploadServiceImpl implements FileUploadService {
@Value("${supporting.documents.location}")
private String supportingDocumentsLocation;
@Override
@Transactional
public Map getResponse(MultipartFile multipartFile) throws IOException {
System.out.println("Documents location is :"+supportingDocumentsLocation);
HashMap<String, Object> map = new HashMap<String, Object>();
Long size = multipartFile.getSize();
String originalFileName=multipartFile.getOriginalFilename();
String contentType = multipartFile.getContentType();
InputStream inputStream = multipartFile.getInputStream();
byte[] bytes = IOUtils.toByteArray(inputStream);
if(size>(5*1024*1024))
{
map.put("fileoriginalsize", size);
map.put("msg", "failed");
map.put("reason", "File size cannot be greater than 5MB");
return map;
}
String newFileName=generateFileName();
// Create the file on server
File serverFile = new File("D:"+File.separator+"Uploads"+ File.separator + newFileName);
BufferedOutputStream outputStream = new BufferedOutputStream(
new FileOutputStream(serverFile));
outputStream.write(bytes);
outputStream.close();
map.put("fileoriginalsize", size);
map.put("contenttype", contentType);
map.put("base64", new String(Base64Utils.encode(bytes)));
map.put("name", newFileName);
return map;
}
}
我app.properties文件：
supporting.documents.location = D:\uploads
但是，當我啓動應用程序時出現錯誤：
Could not resolve placeholder 'supporting.documents.location' in string value "${supporting.documents.location}"
請提出爲什麼我得到的錯誤。謝謝。
謝謝！我早些時候使用它，忘記刪除。感謝很多。 – Jeets
