是CommonsMultipartResolver和春季会议互不干扰

Question

有多个部分配置春季启动的配置

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

这是正确的，成功的工作，当下面的依赖加到

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

以下异常提出：

[错误] org.springframework.web.multipart.support.Missi ngServletRequestPartException： 需要请求部分“文件”不存在需要请求部分 “文件”不存在

哪里错了？

编辑：

它与控制器：

@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 
    {

我添加此配置和正常工作。

@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; 
} 

，并跳过MultipartAutoConfiguration.class这样的：

@SpringBootApplication(exclude = { MultipartAutoConfiguration.class })
