jersey文件服务器,springMVC+jersey实现跨服务器文件上传

本文实例为大家分享了springmvc+jersey实现跨服务器文件上传的具体代码，供大家参考，具体内容如下

1.首先添加所需要的jar包

2.在springmvc的配置文件中添加文件上传解析器

3.jsp页面

请上传头像：

4.文件上传的 js

function fileupload(){

var option = {

type:"post",

url:"${pagecontext.request.contextpath }/user/fileupload.do",

data:{

filename:"imgfile"

},

success:function(redata){

alert(redata.reletivepath);

$("#imgsrc").attr("height",100);

$("#imgsrc").attr("width",100);

$("#imgsrc").attr("src",redata.fullpath);

$("#reletivepath").val(redata.reletivepath);

},

datatype:"json"

};

$("#fm").ajaxsubmit(option);

}

5. controller

/*

* 文件上传

*/

@requestmapping("fileupload")

public @responsebody map fileupload(httpservletrequest request,string filename){

system.out.println(111);

//1.将普通请求转换为多部件请求

multiparthttpservletrequest mr = (multiparthttpservletrequest)request;

//2.根据文件名获取文件对象

commonsmultipartfile mf = (commonsmultipartfile)mr.getfile(filename);

//3.获取文件全名称

string originalfilename = mf.getoriginalfilename();

system.out.println("文件全名称"+originalfilename);

//4.获取后缀

string suffix = originalfilename.substring(originalfilename.lastindexof("."));

system.out.println("后缀"+suffix);

//5.将文件对象转换为字节

byte[] filebytes = mf.getbytes();

//6.获取新的随机文件名

string newfilename="";

simpledateformat sdf = new simpledateformat("yyyymmddhhmmsssss");

int num = (int)(math.random()*899)+100;

newfilename = sdf.format(new date())+num;

system.out.println("新的随机文件名"+newfilename);

//开始上传

//1.创建jesy服务器

client client = client.create();

string fullpath = "http://localhost:8088/fileserviceproject/upload/"+newfilename+suffix;

//把文件关联到远程服务器

webresource wr = client.resource(fullpath);

//2.相对路径

string reletivepath = "/upload/"+newfilename+suffix;

//3.上传

wr.put(string.class, filebytes);

map map = new hashmap();

map.put("fullpath", fullpath);

map.put("reletivepath", reletivepath);

return map;

}
