二、    初始化设置:

$("#fuploadinput").fileinput({

uploadAsync:true,//默认异步上传

previewFileType:"pdf",

maxFileCount: 2,

maxFileSize: 5120,

maxFilePreviewSize: 25600,// 25 MB

msgFilesTooMany:"选择的上传文件个数 ({n}) 超出最大文件的限制个数 {m}. 请重新上传!",

dropZoneTitle:"拖拽文件到这里或者点击选择上传 …",

uploadExtraData:function() {

//注意:一般只支持js,

varfileuploadtitleval = document.getElementById("fileuploadtitleid").value;

if(fileuploadtitleval =="")

{

alert(11);

}else{

return{

'fileuploadtitle':fileuploadtitleval,

};

}

},

});

//异步上传成功结果处理

$("#fuploadinput").on("fileuploaded",function(event, data, previewId, index) {

});

//异步上传错误结果处理

$("#fuploadinput").on('fileerror',function(event, data, msg) {

});

①:FileuploadController

@Resource

FileuploadOperatorfileuploadOperator;

/**

*@throwsException

rep.setHeader("Cache-Control","no-cache");

HttpSessionhttpSession=req.getSession();

Stringuserid=httpSession.getAttribute("userid").toString();

Mapusermso=newHashMap<>();

usermso.put("userid",userid);

Mapmap=fileuploadOperator.queryUser(usermso);

Stringfileuploadtitle=req.getParameter("fileuploadtitle");

Mapumso=newHashMap();

umso.put("fileuploadname",map.get("nickname"));

umso.put("fileuploadtitle",fileuploadtitle);

try{

Stringfilerealpath="";

StringBufferurl=req.getRequestURL();

StringtempContextUrl=url.delete(url.length() -req.getRequestURI().length(),url.length()).append("/").toString();

System.out.println(tempContextUrl);

MultipartHttpServletRequestmultipartRequest= (MultipartHttpServletRequest)req;

MultipartFilefile1=multipartRequest.getFile("file_data");

Mapmp=newHashMap();

mp.put("msg",msg);

JSONObjectjsonobj= JSONObject.fromObject(mp);

Stringjson=jsonobj.toString();

rep.getWriter().print(json);

}else{

mp.put("msg","上传失败!格式不正确,只允许上传pdf! ");

JSONObjectjsonobj= JSONObject.fromObject(mp);

}

}

② FileuploadOperator

// 保存pdf的方法

publicvoidsaveFile(StringfilePath,byte[]content)throwsException {

BufferedOutputStreambos=null;

try{

Filefile=newFile(filePath);

// 判断文件路径是否存在

if(!file.getParentFile().exists()) {

file.getParentFile().mkdirs();

}

/*if (file.exists()) {

throw new Exception("已存在名称相同的文件,请修改文件名重新上传!");

}*/

// 创建文件(这是个空文件,用来写入上传过来的文件的内容)

file.createNewFile();

bos=newBufferedOutputStream(newFileOutputStream(file));

bos.write(content);

bos.flush();

}catch(FileNotFoundExceptione) {

thrownewFileNotFoundException("pdf文件不存在");

}finally{

if(null!=bos) {

bos.close();

}

}

}
