CommonSmultipartresolver和春季会议相互打扰

Question

Spring Boot中有多部分配置的配置

@Bean
public CommonsMultipartResolver multipartResolver() {
CommonsMultipartResolver resolver = new CommonsMultipartResolver();
resolver.setDefaultEncoding("utf-8");
resolver.setMaxInMemorySize(20480);
resolver.setMaxUploadSize(2048000000);
return resolver;
}

添加以下依赖关系

时，这是对的，并且成功地工作了

           <dependency>
                <groupId>org.springframework.session</groupId>
                <artifactId>spring-session</artifactId>
            </dependency>

提出以下例外：

[错误] org.springframework.web.multipart.support.missingservletrequestpartexception： 所需的请求部分"文件"不存在所需的请求零件 "文件"不存在

哪里错了？

编辑：

它是相关的控制器：

@RequestMapping(value={"/save"}, method={org.springframework.web.bind.annotation.RequestMethod.POST})
  @ResponseBody
  public FileProviderDto save(@RequestParam("file") MultipartFile file, @RequestParam String fileCode)
     throws IOException, SQLException
   {

我添加此配置并正确工作。

@Bean
public CommonsMultipartResolver multipartResolver() {
    CommonsMultipartResolver resolver = new CommonsMultipartResolver();
    resolver.setDefaultEncoding("utf-8");
    resolver.setMaxInMemorySize(20480);
    resolver.setMaxUploadSize(2048000000);
    return resolver;
}
@Bean
@Order(0)
public MultipartFilter multipartFilter() {
    MultipartFilter multipartFilter = new MultipartFilter();
    multipartFilter.setMultipartResolverBeanName("multipartResolver");
    return multipartFilter;
}

和跳过多Artartautoconfiguration.Class：

@SpringBootApplication(exclude = { MultipartAutoConfiguration.class })
