java struts2上传文件(ajaxfileupload.js)

html部分代码:

<input type='file' size='20' style='height: 25px;width:60%;' name='file' id='corp_icon_id'>
<input type='button' onclick="uploadFile('corp_icon_id')" value='上传'>

 

js部分代码:

function uploadFile(fileId) {
var fileIdValue = $("#" + fileId).val();
if (!fileIdValue) {
mini.alert('请选择要上传的文件！', '提示');
} else {
doSaveByfreshFlag(false);
jQuery.ajaxFileUpload({
url : '<%=basePath%>basicData/OperationUnits_uploadFile.action',
secureuri : false,
fileElementId : fileId,
dataType : 'text',
type : "POST",
data : {
"fileFullName":fileIdValue,
"tcorp.corp_id":corp_id
},
success : function(data, status) {
window.location.href ="basicData/OperationUnits_edit.action?primaryKey=" + corp_id +"&optype=edit";
},
error : function(data, status, e) {
mini.alert('上传失败！', '提示');
}
});
return false;
}
 
}

 

java部分代码：

String Serverpath = this.getServletContext().getRealPath("/");
String uploadFullPath = Serverpath + uploadRelativePath;
File tempFile = this.getFile();
File outFile = new File(uploadFullPath); // 判断文件夹是否存在,如果不存在则创建文件夹
if (!outFile.exists()) {
outFile.mkdirs();
}
UUIDHexGenerator t = new UUIDHexGenerator(); // 文件名不能重复
String saveRelativeFileName = uploadRelativePath + t.generate() + suffixName;

}
 
this.tcorp.setCorp_icon(saveRelativeFileName);
