Я использую Spring Boot 2.0.0 для загрузки файлов на сервер и получаю эту ошибку:
Servlet.service () для сервлета [dispatcherServlet] в контексте с путем [/ project] выдало исключение [Ошибка обработки запроса;вложенным исключением является org.springframework.web.multipart.MultipartException: не удалось проанализировать многочастный запрос сервлета;вложенное исключение: java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: непредвиденное чтение EOF в сокете] с основной причиной

Это мой интерфейс:
<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">

</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
});
BACKEND: мой контроллер:
@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)
Я также добавил многочастный преобразователь
@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
Tomcat context.xml
<Context allowCasualMultipartParsing="true" path="/">
<Resources cachingAllowed="true" cacheMaxSize="100000" />
</context>
Tomcat web.xml
<session-config>
<session-timeout>60</session-timeout>
</session-config>
Tomcat servlet.xml
<Connector port="1050"
maxThreads="400" minSpareThreads="25" maxSpareThreads="75"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionUploadTimeout="36000000" connectionTimeout="60000" disableUploadTimeout="false"
/>
В чем может быть причина этой ошибки?
