它将进入服务器。这是我的DocumentUploadController.java
@Controller
public class DocumentUploadController {
@RequestMapping(value="/newDocument", headers = "'Content-Type': 'multipart/form-data'", method = RequestMethod.POST)
public void UploadFile(MultipartHttpServletRequest request, HttpServletResponse response) {
Iterator<String> itr=request.getFileNames();
MultipartFile file=request.getFile(itr.next());
String fileName=file.getOriginalFilename();
System.out.println(fileName);
}
}
如何解决这个问题
若有人告诉我如何从angularJS发送文件和其他表单数据并将其放入服务器中,那个将是非常棒的

我的服务器正在其他端口8080上运行。我是尤森·约曼、格伦特和鲍尔。我已经提到了服务器端口。所以它转到服务器并运行它,然后抛出异常

我遇到了同样的问题,甚至在更新transformRequest之后也遇到了同样的问题。”有些情况下,标题边界似乎设置不正确 接下来,问题就解决了。从位置提取 通过设置“内容类型”:未定义,浏览器为我们将内容类型设置为多部分/表单数据,并填充正确的边界。手动设置“内容类型”:多部分/表单数据将无法填写请求的边界参数 不确定这是否对任何人有帮助,但可能会使人们更容易看到这篇文章。。。至少,这让它变得不那么困难。你可以试试这个 .js .爪哇 这是基于 有一个文件上传的好例子 导言 我也遇到了同样的问题,并找到了一个完整的解决方案,将json和文件从基于angular的页面发送到SpringMVC方法 主要问题是$http没有发送正确的内容类型头(我将解释原因) 关于多部分/表单数据的理论 要同时发送json和文件,我们需要发送一个多部分/表单数据,这意味着“我们在正文中发送不同的项,并用一个特殊的分隔符分隔”。这个特殊的分隔符称为“boundary”,它是一个字符串,在任何要发送的元素中都不存在 服务器需要知道正在使用哪一个边界,因此必须在内容类型头中指示它(内容类型多部分/表单数据;边界=$theu boundary\u used) 所以。。。需要两件事:
//create form data to send via POST
var formData=new FormData();
console.log('loading json info');
formData.append('infoClient',angular.toJson(client,true));
// !!! when calling formData.append the boundary is auto generated!!!
// but... there is no way to know which boundary is being used !!!
console.log('loading file);
var file= ...; // you should load the fileDomElement[0].files[0]
formData.append('file',file);
//create the ajax request (traditional way)
var request = new XMLHttpRequest();
request.open('POST', uploadUrl);
request.send(formData);
@RequestMapping(value = "/", method = RequestMethod.POST)
public @ResponseBody Object newClient(
@RequestParam(value = "infoClient") String infoClientString,
@RequestParam(value = "file") MultipartFile file) {
// parse the json string into a valid DTO
ClientDTO infoClient = gson.fromJson(infoClientString, ClientDTO.class);
//call the proper service method
this.clientService.newClient(infoClient,file);
return null;
}
然后,在Spring方法中,您可以有如下内容:
//create form data to send via POST
var formData=new FormData();
console.log('loading json info');
formData.append('infoClient',angular.toJson(client,true));
// !!! when calling formData.append the boundary is auto generated!!!
// but... there is no way to know which boundary is being used !!!
console.log('loading file);
var file= ...; // you should load the fileDomElement[0].files[0]
formData.append('file',file);
//create the ajax request (traditional way)
var request = new XMLHttpRequest();
request.open('POST', uploadUrl);
request.send(formData);
@RequestMapping(value = "/", method = RequestMethod.POST)
public @ResponseBody Object newClient(
@RequestParam(value = "infoClient") String infoClientString,
@RequestParam(value = "file") MultipartFile file) {
// parse the json string into a valid DTO
ClientDTO infoClient = gson.fromJson(infoClientString, ClientDTO.class);
//call the proper service method
this.clientService.newClient(infoClient,file);
return null;
}
Carlos Verdes的回答无法与我的$http拦截器配合使用,该拦截器添加了授权头等等。因此,我决定添加到他的解决方案中,并使用$http创建我的解决方案 客户端角度(1.3.15) 我的表单(使用controllerAs语法)假设一个文件和一个简单对象包含我们需要发送到服务器的信息。在这种情况下,我使用一个简单的名称和类型String属性
<form>
<input type="text" ng-model="myController.myObject.name" />
<select class="form-control input-sm" ng-model="myController.myObject.type"
ng-options="type as type for type in myController.types"></select>
<input class="input-file" file-model="myController.file" type="file">
</form>
其次,我使用实例方法create创建了一个名为myObject的工厂,该实例方法允许我在调用服务器上的create时转换数据。该方法将所有内容添加到FormData对象中,并使用transformRequest方法()对其进行转换。将头设置为未定义非常重要。(旧的角度版本可能需要设置未定义的内容)。这将允许自动设置多重数据/边界标记(参见Carlos的帖子)
客户端只需在myController中实例化一个新的myObject,并在提交表单时调用controller的create函数中的create方法
this.myObject = new myObject();
this.create = function() {
//Some pre handling/verification
this.myObject.create(this.myObject, this.file).then(
//Do some post success/error handling
);
}.bind(this);
服务器端弹簧(4.0)
在RestController上,我现在可以简单地执行以下操作:(假设我们有一个pojomyobject)
请注意,我没有使用requestparameters,只是让spring进行JSON到POJO/DTO的转换。确保您也正确设置了MultiPartResolverbean,并将其添加到pom.xml中。(如果需要,还有Jackson Mapper)

这是一个烦人的问题,我希望能解决它!!使用XMLHttpRequest而不设置内容类型对我来说很有效,谢谢。我的类似问题经验在[此处][1][1]中分享:URL不是更容易访问的,请将其作为推荐的邮政编码并将引用放在响应末尾。URL对我来说很有用
@RequestMapping(method = RequestMethod.POST)
@Secured({ "ROLE_ADMIN" }) //This is why I needed my $httpInterceptor
public void create(MyObject myObject, MultipartFile file) {
//delegation to the correct service
}
