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

<!-- 文件上传的解析器 -->
 <bean id="multipartresolver" class="org.springframework.web.multipart.commons.commonsmultipartresolver">
  <!-- 文件上传大小的限制 -->
  <property name="maxuploadsize" value="5000000"></property>
  <property name="defaultencoding" value="utf-8"></property>
</bean>

3.jsp页面 

<form id="fm" action="" method="post">
 <p>
 <img src="" alt="" id="imgsrc"/>
 请上传头像：<input type="file" name="imgfile" id="imgfile" οnchange="fileupload();"/>
 <input type="hidden" id="reletivepath" name="reletivepath" value="">
 </p>
</form>

4.文件上传的 js

 <!-- 文件上传js -->
<script type="text/javascript">
 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);
 }
</script>

5. controller

/*
 * 文件上传
 */
 @requestmapping("fileupload")
 public @responsebody map<string , string> 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<string , string> map = new hashmap<string, string>();
 map.put("fullpath", fullpath);
 map.put("reletivepath", reletivepath);
 return map;
 }
