本文介绍了如何使用角度JS Spring MVC的上传分段文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我要上传使用angularjs和文件的Spring MVC
我在应用程序的context.xml一个multipartResolver豆。
＆LT; MVC：注解驱动/＆GT; ＆LT;豆的id =multipartResolver
类=org.springframework.web.multipart.commons.CommonsMultipartResolver＆GT;
＆LT;属性名=maxUploadSize值=2097152/＆GT;
＆LT; /豆＆GT;
我的形式是这样的：
＆LT;形式方法=邮报ID =fromFileUploadENCTYPE =的multipart / form-data的
NG-提交=continueFileUpload（）＆GT;
＆LT; DIV CLASS =表单组＆GT;
＆LT;标签类=控制标签COL-SM-4 COL-XS-12为=quoteIdentifier＆GT;引用标识符：＆LT; /标签＆gt;
＆LT; DIV CLASS =COL-XS-4输入-MAX＆GT;
＆LT;选择类型=文本级=表格控NAME =quoteIdentifierID =quoteIdentifierNG模型=quoteIdentifierNG选项=＆GT;
＆LT;选项风格=显示：无VALUE =＆GT;选择与LT; /选项＆GT;
＆LT; /选择＆GT;
＆LT; / DIV＆GT;
＆LT; / DIV＆GT;
＆LT; DIV CLASS =表单组＆GT;
＆LT;标签类=控制标签COL-SM-4 COL-XS-12为=文件＆gt;请上传的文件：其中，跨度类=必需＆GT; *＆LT; / SPAN＆GT; ＆LT; /标签＆gt;
＆LT; DIV CLASS =COL-XS-4输入-MAX控制＆GT;
＆LT;输入类=inline-block的TYPE =文件名称=文件NG-模式=文件数据规则要求的=真正的ID =文件接受=CSV，的.xsl，的.xml，.MPP，应用程序/ vnd.ms - Excel的＆GT;
＆LT; / DIV＆GT;
＆LT;跨度ID =vaildFile级=TEXT-成功图标确定隐藏＆GT;有效的文件＆LT; / SPAN＆GT; ＆LT;跨度ID =invaildFile级=TEXT-错误图标删除隐藏＆GT;无效的文件＆LT; / SPAN＆GT;
＆LT; / DIV＆GT;
＆LT; DIV CLASS =盒子头＆GT;
＆LT; DIV CLASS =行动＆GT;
＆LT;按钮式=提交级=BTN BTN-小学＆GT;
＆LT; I类=图标右箭头＆GT;＆LT; / I＆GT;继续
＆LT; /按钮＆GT;
＆LT; / DIV＆GT;
＆LT; / DIV＆GT;
＆LT; /表及GT;$ scope.continueFileUpload =功能（）{
VAR的uploadURL = +的serverUrlcontinueFileUpload
VAR FORMDATA =新FORMDATA（）;
formData.append（文件，file.files [0]）;
$ HTTP（{
方法：POST，
网址：的uploadURL，
标题：{内容类型：虚假}，
数据：FORMDATA，
transformRequest：功能（数据，headersGetterFunction）{
返回的数据;
}
}）
.success（功能（数据，状态）{
警报（成功）;
}）};
春季控制器：
@Controller
公共类FileUploadController {
@RequestMapping（值=/ continueFileUpload，方法= RequestMethod.POST）
@ResponseBody
公共字符串continueFileUpload（HttpServletRequest的请求，
HttpServletResponse的响应）{
MultipartHttpServletRequest mRequest;
尝试{
mRequest =（MultipartHttpServletRequest）请求;
mRequest.getParameterMap（）; 迭代器＆LT;串GT; ITR = mRequest.getFileNames（）;
而（itr.hasNext（））{
MultipartFile MFILE = mRequest.getFile（itr.next（））;
字符串文件名= mFile.getOriginalFilename（）;
的System.out.println（文件名）;
}
}赶上（例外五）{
e.printStackTrace（）;
}
返回null;
}
当我想补充的multipart / form-data的页眉我得到 **的请求被拒绝，因为没有多部分边界发现** 例外
如果我没有补充，我得到 org.apache.catalina.connector.RequestFacade不能转换为org.springframework.web.multipart.MultipartHttpServletRequest
解决方案
$ scope.continueFileUpload =功能（）{
VAR的uploadURL = +的serverUrlcontinueFileUpload
VAR FORMDATA =新FORMDATA（）;
formData.append（文件，file.files [0]）;
$ HTTP（{
方法：POST，
网址：的uploadURL，
标题：{'内容类型'：未定义}，
数据：FORMDATA，
transformRequest：功能（数据，headersGetterFunction）{
返回的数据;
}
}）
.success（功能（数据，状态）{
警报（成功）;
}）};
I am trying to upload a file using angularjs and spring MVC
I have a multipartResolver bean in application-context.xml.
<mvc:annotation-driven />
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="2097152" />
</bean>
my form look like this:
<form method="post" id="fromFileUpload" enctype="multipart/form-data"
ng-submit="continueFileUpload()">
<div class="form-group">
<label class="control-label col-sm-4 col-xs-12" for="quoteIdentifier">Quote Identifier : </label>
<div class="col-xs-4 input-max">
<select type="text" class="form-control " name="quoteIdentifier" id="quoteIdentifier" ng-model="quoteIdentifier" ng-options="">
<option style="display: none" value="">Choose</option>
</select>
</div>
</div>
<div class="form-group">
<label class="control-label col-sm-4 col-xs-12" for="file">Please upload the file : <span class="required">*</span> </label>
<div class="col-xs-4 input-max controls ">
<input class="inline-block" type="file" name="file" ng-model="file" data-rule-required="true" id="file" accept=".csv,.xsl,.xml,.mpp,application/vnd.ms-excel">
</div>
<span id="vaildFile" class="text-success icon-ok hide">Valid File</span> <span id="invaildFile" class="text-error icon-remove hide"> Invalid File</span>
</div>
<div class="box-header">
<div class="actions">
<button type="submit" class="btn btn-primary">
<i class="icon-arrow-right"></i> Continue
</button>
</div>
</div>
</form>
$scope.continueFileUpload=function (){
var uploadUrl=serverUrl+"continueFileUpload";
var formData=new FormData();
formData.append("file",file.files[0]);
$http({
method: 'POST',
url: uploadUrl,
headers: {'Content-Type': false},
data: formData,
transformRequest: function(data, headersGetterFunction) {
return data;
}
})
.success(function(data, status) {
alert("success");
})
};
spring controller:
@Controller
public class FileUploadController {
@RequestMapping(value = "/continueFileUpload", method = RequestMethod.POST)
@ResponseBody
public String continueFileUpload(HttpServletRequest request,
HttpServletResponse response){
MultipartHttpServletRequest mRequest;
try {
mRequest = (MultipartHttpServletRequest) request;
mRequest.getParameterMap();
Iterator<String> itr = mRequest.getFileNames();
while (itr.hasNext()) {
MultipartFile mFile = mRequest.getFile(itr.next());
String fileName = mFile.getOriginalFilename();
System.out.println(fileName);
}
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
When I add multipart/form-data for the header I get **the request was rejected because no multipart boundary was found** exceptions
If I didnt add I get org.apache.catalina.connector.RequestFacade cannot be cast to org.springframework.web.multipart.MultipartHttpServletRequest
解决方案
$scope.continueFileUpload=function (){
var uploadUrl=serverUrl+"continueFileUpload";
var formData=new FormData();
formData.append("file",file.files[0]);
$http({
method: 'POST',
url: uploadUrl,
headers: {'Content-Type': undefined},
data: formData,
transformRequest: function(data, headersGetterFunction) {
return data;
}
})
.success(function(data, status) {
alert("success");
})
};
