java - org.springframework.web.multipart.MultipartException：无法解析多部分 servlet 请求

Question

我正在使用 Spring Boot 2.0.0 将文件上传到服务器，但出现此错误：

servlet [dispatcherServlet] 在路径 [/project] 的上下文中的 Servlet.service() 引发异常 [请求处理失败；嵌套异常是 org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request；嵌套异常是 java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: Unexpected EOF read on the socket] 根本原因

这是我的前端：

<form class="form"  enctype="multipart/form-data"  >
             <div class="book__row form__group ">
                <select id="dropdown-category" name="options" class="form__input" required>
                    <option value="0">Wählen Sie eine Kategorie aus</option>
                </select>
            </div>
            <div class="book__row form__group ">
                <select id="dropdown-subcategory" name="options" class="form__input" required>
                </select>
            </div>

            <div class="form__group">
                <input type="text" class="form__input form__input--blue-border" placeholder="NAME" id="filename" required>
                <label for="title" class="form__label">NAME</label>
            </div>

            <div class="form__group">
                <textarea id="description" class="form__input form__input--blue-border " rows="4" cols="50" name="comment" form="usrform"
                    required> BESCHREIBUNG
                                </textarea>

            </div>

            <div class="form__group input-file-container">
                <input class="input-file" id="fileStream" type="file" required>
                <label tabindex="0" for="my-file" class="input-file-trigger">Datei hochladen</label>
                <p class="file-return"></p>
            </div>


     <div class=" form__group input-file-container" id="addBinaryDoc">
                <input class="input-file"  type="submit">
                <label tabindex="0" for="form-btn" class="input-file-trigger">Dokument hinzufügen</label>
                <p class="file-return"></p>
            </div>

        </form>





 JS
   var data = new FormData();
    data.append("fileStream", file);
    data.append("metadata", new Blob([JSON.stringify(doc)], { type: "application/json" }));

    return $.ajax({
         type: "POST",
        url: '/my/path',
        data: data,
        enctype: 'multipart/form-data',
        cache: false,
        contentType: false,
        processData: false


    });

后端：我的控制器：

 @RequestMapping(value = "save",headers = "content-type=multipart/*", method = { RequestMethod.POST 
 }, consumes = "multipart/form-data")
 @ResponseBody
 public void saveDocument(@RequestParam("fileStream") MultipartFile   multipartFile, 
 @RequestPart(name = "metadata", required = false) @Valid Document uploadedDocument)

我还添加了一个多部分解析器

 @Bean
  public MultipartResolver multipartResolver() {
    MultipartResolver resolver = new StandardServletMultipartResolver();
    return resolver;
  }

 @Bean
  MultipartConfigElement multipartConfigElement() {
    MultipartConfigFactory factory = new MultipartConfigFactory();
     factory.setMaxFileSize("5120MB");
     factory.setMaxRequestSize("5120MB");
    return factory.createMultipartConfig();
 }

application.properties：

spring.servlet.multipart.max-file-size=5MB
spring.servlet.multipart.max-request-size=10MB
spring.servlet.multipart.enabled=true

雄猫context.xml

  <Context allowCasualMultipartParsing="true" path="/">
    <Resources cachingAllowed="true" cacheMaxSize="100000" />
   </context>

雄猫web.xml

<session-config>
    <session-timeout>60</session-timeout>
</session-config>

雄猫servlet.xml

  <Connector port="1050"
maxThreads="400"   minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionUploadTimeout="36000000" connectionTimeout="60000" disableUploadTimeout="false" 
/>

此错误的原因可能是什么？
