本项目使用ssh开发，上传功能的时候上传的附件如果超过2个，则action直接返回input.里面的上传方法也不走，附件是2个或者2个一下的时候则没问题。本人不知道是什么原因。求解答。
我的代码：
Action的：
public class FileAction extends ActionSupport {
// 上传文件存放路径
private final static String UPLOADDIR = "/upload";
// 上传文件集合
private List<File> file;
// 上传文件名集合
private List<String> fileFileName;
// 上传文件内容类型集合
private List<String> fileContentType;
private Integer txtid;
public Integer getTxtid() {
return txtid;
}
public void setTxtid(Integer txtid) {
this.txtid = txtid;
}
private TblTextDao tdao;
private TblText ttxt;
public List<File> getFile() {
return file;
}
public void setFile(List<File> file) {
this.file = file;
}
public List<String> getFileFileName() {
return fileFileName;
}
public void setFileFileName(List<String> fileFileName) {
this.fileFileName = fileFileName;
}
public List<String> getFileContentType() {
return fileContentType;
}
public void setFileContentType(List<String> fileContentType) {
this.fileContentType = fileContentType;
}
public TblTextDao getTdao() {
return tdao;
}
public void setTdao(TblTextDao tdao) {
this.tdao = tdao;
}
public TblText getTtxt() {
return ttxt;
}
public void setTtxt(TblText ttxt) {
this.ttxt = ttxt;
}
public String execute() throws Exception {
List<String> listpath = new ArrayList<String>();
Map session = ActionContext.getContext().getSession();
List<Boolean> listbool = new ArrayList<Boolean>();
if (file != null) {
if (file.size() > 0) {
for (int i = 0; i < file.size(); i++) {
// 循环上传每个文件
boolean b = upload(i,listpath);
if (b = false) {
listbool.add(b);
}
}
}
}
if (listbool.size() == 0) {
String paths = "";
for (int i = 0; i < listpath.size(); i++) {
if (listpath.size() == 1) {
paths = listpath.get(i);
} else {
paths = paths + "|" + listpath.get(i);
}
}
ttxt.setImagePath(paths);
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
ttxt.setTextCreatTime(formatter.format(new Date()));
TblUser u = new TblUser();
u = (TblUser) session.get("user");
ttxt.setTblUser(u);
boolean b = tdao.addText(ttxt);
if (b) {
session.put("message", "添加成功");
return "addSuccess";
} else {
session.put("message", "对不起，上传失败");
return "addInput";
}
} else {
session.put("message", "对不起，上传失败");
return "addInput";
}
}
public boolean upload(int i,List<String> listpath) {
Map session = ActionContext.getContext().getSession();
try {
InputStream in = new FileInputStream(file.get(i));
String dir = ServletActionContext.getRequest().getRealPath(
UPLOADDIR);
String fileName = this.getFileFileName().get(i);
listpath.add(fileName);
if (fileName.endsWith(".exe")) {
return false;
}
File uploadFile = new File(dir, fileName);
OutputStream out = new FileOutputStream(uploadFile);
byte[] buffer = new byte[1024 * 1024];
int length;
while ((length = in.read(buffer)) > 0) {
out.write(buffer, 0, length);
}
in.close();
out.close();
} catch (FileNotFoundException ex) {
System.out.println("上传失败!");
ex.printStackTrace();
return false;
} catch (IOException ex) {
System.out.println("上传失败!");
ex.printStackTrace();
return false;
}
return true;
}
}
