我最近在我的应用程序中启动了Spring Boot。 有一个文件上传实用程序，使用tomcat8时工作正常，但切换到Spring启动后它无法正常工作。
以下是代码。
JSP
<form id="fileupload" action="/myApp/upload" method="POST" enctype="multipart/form-data">
<table id="files" style="border-spacing:0px 5px;margin-top:5px;">
<tbody><tr>
<td><input type="file" class="btn btn-info" name="files" id="files0"></td>
</tr></tbody>
</table>
</form>
控制器
@RequestMapping(method = RequestMethod.POST, consumes = "multipart/form-data")
public String upload(@RequestParam("files") MultipartFile files, @RequestHeader HttpHeaders httpHeaders, Model model, Locale locale) {
LOGGER.debug("Entering upload");
}
Spring Boot配置：
@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class, MultipartAutoConfiguration.class })
@Configuration
@ComponentScan
@ImportResource(value = "classpath:/context.xml")
public class MyApplication {
public MyApplication() {
super();
}
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
}

我在我的启动应用程序类上尝试过@SpringBootApplication，但这没有用。我正在使用嵌入式tomcat。
我搜索了各种博客和SO问题，但无法解决。 请帮忙。
