这篇文章主要介绍了SpringMVC上传图片代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
1、前端H5
<div class="container-fluid">
<!-- <div id="panel-advancedoptions"> -->
<div class="row">
<div class="col-md-12">
<div class="panel panel-midnightblue">
<div class="panel-heading">
<h2>修改头像</h2>
</div>
<div class="panel-body">
<div class="row">
<div class="col-md-1">
<button type="button" class="btn btn-primary btn-sm" id="btn_upload" >
<span class="fa fa-upload"></span> 上传头像图片
</button>
</div>
<div class="col-md-11">
<h5></h5>（仅限上传单张10M以下png、jpg图片）</h5>
<input type="file" class="hidden" id="InputFile" />
</div>
</div>
</br>
<div class="row">
<div class="col-md-6">
<img src="images/UserAvatars/robo.jpg" class="img-thumbnail uploadImges" >
</div>
</div>
</div>
</div>
</div>
</div>
<!-- </div> -->
</div>
2、JS
$("#btn_upload").click(function(){
$("#InputFile").trigger("click");
openUploads("InputFile");
});
function openUploads(id){
$("#"+id).unbind().change(function(){
var formdata = new FormData();
formdata.append('file',$("#"+id)[0].files[0]); //获取图片信息
//console.log($("#"+id)[0].files[0]);
$.ajax({
type: 'POST',
url: "http://localhost:8078/lifeTrackDB/UploadUserAvatars",
data:formdata,
cache:false,
dataType: 'json',
processData:false,
contentType:false,
success : function (result)
{
console.log(result);
if (result.status)
{
//$('#'+id).attr('src','images/UserAvatars/'+result.message);
alert(result.message);
}
else
{
$.alert(result.message,'');
}
}
});
});
}
3、JAVA后台
@RequestMapping(value="/UploadUserAvatars")
@ResponseBody
public void UploadUserAvatars(HttpServletRequest request,HttpServletResponse response,
@RequestParam(value = "file") List<MultipartFile> files) throws Exception{
String path=System.getProperty("user.dir");
if (null != files || 0 != files.size()) {
for(MultipartFile file:files) {
//System.err.println("文件名：" + file.getOriginalFilename() + "---contentType：" + file.getContentType());
file.transferTo(new File(path+"/UserAvatars/"+file.getOriginalFilename()));
response.getWriter().write("{\"status\": true, \"code\": \"200\",\"message\":\"上传成功\"}");
}
}else {
//response.getWriter().write("handleCallback({\"status\": false, \"code\": \"200\",\"message\":\"上传失败\"})");
response.getWriter().write("{\"status\": false, \"code\": \"200\",\"message\":\"上传失败\"}");
}
}
