struts2上传问题

Question

用的是struts2上传文件，现在上传有内容的文件是好使的，但是上传空文件就报错，就是txt里一个字也没写
报错java.io.FileNotFoundException:
D:\Tomcat 6.0\work\Catalina\localhost\ecdoms\upload__65a77bd1_12d96abb9bf__7fd5_00000661.tmp (系统找不到指定的文件。)

也就是new FileInputStream(uploads.get(i)));这句报错了
怎么写能避免这个错误

[color=red]action中代码[/color]DomsEnclosure el=new DomsEnclosure();
el.setFileContent(Hibernate.createBlob(new FileInputStream(uploads.get(i))));
el.setFileName(uploadsFileName.get(i));

el.setUploadTime(date);
el.setUploador(loginName);
el.setBelongModule(2L);
el.setFileType(uploadsContentType.get(i));
el.setFkId(exeJob.getId());
service.saveEnclosure(el);

[color=darkred]实体中代码[/color]public class DomsEnclosure implements java.io.Serializable {

// Fields    

 private String id;
 private String fkId;
 private String fileName;
 private String fileType;
 private String uploador;
 private Date uploadTime;
 private Long belongModule;
 private Blob fileContent;

Answer 1

fileContent 这个是文件内容嘛。 如果它为空就不读取内容，但是创建该文件。
