var body = $("#body").textbox('getValue');
console.log("type:"+type+"-----title:"+title+"-----body:"+body);
$("#personnelForm").ajaxSubmit({
type: "POST",
url:"../../addPersonnelNotice",
dataType: "json",
data:{
type:type,
title:title,
body:body
},
success:function(data){
if(data.info == "success"){
$.messager.alert('提示', '通知发布成功！', 'info');
}else{
$.messager.alert('错误', '数据加载失败！', 'error');
}
},
error:function(){
$.messager.alert('错误', '数据加载失败！', 'error');
}
});
}
后台代码
@RequestMapping(value="/addPersonnelNotice",method = RequestMethod.POST)
public void addPersonnelNotice(HttpServletRequest request,HttpServletResponse response,
@RequestParam(required=false)MultipartFile file, @RequestParam("body")String body,
@RequestParam("type")String type,@RequestParam("title")String title){
HttpSession session = request.getSession();
User user = (User) session.getAttribute(Constant.USER_SESSION_KEY);
int fileType = Integer.parseInt(request.getParameter("type"));
String createDate = sdf.format(new Date());
String createUser = user.getUserName();
PersonnelNotice personnelNotice = new PersonnelNotice( title, body, createUser, createDate, fileType);
if(file != null){
//上传附件
personnelNotice.setAnnexFileName(file.getOriginalFilename());
File uploadFile = new File("D:\\"+ System.currentTimeMillis()+ file.getOriginalFilename());
personnelNotice.setAnnexFilePath(uploadFile.getPath());
try {
FileUtils.copyInputStreamToFile(file.getInputStream(), uploadFile);
} catch (IOException e) {
e.printStackTrace();
}
}
JSONObject result = new JSONObject();
if(service.addPersonnelNotice(personnelNotice)){
result.put(Constant.INFO, Constant.SUCCESS);
}else{
result.put(Constant.INFO, Constant.FAIL);
}
writer(response,result);
}
