最简洁的struts动态多文件上传

使用HashMap了

JSP:

<form accept-charset="UNKNOWN" enctype="multipart/form-data" method="get">

java 代码

JSP:

<form enctype="multipart/form-data">
<input TYPE="file" SIZE="50" NAME="contentFile[0]">
<input TYPE="file" SIZE="50" NAME="contentFile[1]">
...
</form>

ActionForm:

private Map files = new HashMap();


/**
* @return Returns the File Count.
*/
public int getFileCount() {
return files.size();
}
public void setFileCount(int fileCount) {
this.fileCount = fileCount;
}

/**
* @return Returns the Content .
*/
public FormFile getContentFile(int key){
return (FormFile)files.get(new Integer(key));
}

public void setContentFile(int key,FormFile value){
files.put(new Integer(key),value);
}


Action:

form.getContentFile(i).getFileName()

<input maxlength="2147483647" name="contentFile[0]" size="50" type="file">
<input maxlength="2147483647" name="contentFile[1]" size="50" type="file">
