Grails 2.4限制/最大上载大小

关于这个问题，我无法让它在Grails2.4上运行

我已将此添加到我的Grails应用程序中：

资源.groovy

beans = {
    multipartResolver(CustomMultipartResolver) {
        maxUploadSize = 2000000
    }
}

添加到BootStrap.groovy

public class CustomMultipartResolver extends CommonsMultipartResolver {

   static final String FILE_SIZE_EXCEEDED_ERROR = "fileSizeExceeded"

   public MultipartHttpServletRequest resolveMultipart(HttpServletRequest request) {

      try {
         return super.resolveMultipart(request)
      } catch (MaxUploadSizeExceededException e) {
         request.setAttribute(FILE_SIZE_EXCEEDED_ERROR, true)
         return new DefaultMultipartHttpServletRequest(request, new LinkedMultiValueMap(), [:])
      } catch (SizeLimitExceededException e) {
         request.setAttribute(FILE_SIZE_EXCEEDED_ERROR, true)
         return new DefaultMultipartHttpServletRequest(request, new LinkedMultiValueMap(), [:])
      }
   }
}

在控制器中：

if (request.getAttribute(CustomMultipartResolver.FILE_SIZE_EXCEEDED_ERROR)) {
   ModActionFile.errors.reject("MyDomain.fileSizeTooLarge")
   redirect(controller:'MyDomain', action:'create',params:params)
} else {...

我得到这个错误

2008年是很久以前的事了

错误消息非常清楚-您要么向构造函数传递了不正确的类型，要么传递了错误数量的参数

Grails2.4.4使用Spring4.0.7，该类有两个构造函数：

public DefaultMultipartHttpServletRequest(HttpServletRequest request, MultiValueMap<String, MultipartFile> mpFiles,
        Map<String, String[]> mpParams, Map<String, String> mpParamContentTypes)

你可以看到

这应该起作用：

class CustomMultipartResolver extends CommonsMultipartResolver {

   static final String FILE_SIZE_EXCEEDED_ERROR = 'fileSizeExceeded'

   MultipartHttpServletRequest resolveMultipart(HttpServletRequest request) {
      try {
         super.resolveMultipart request
      }
      catch (MaxUploadSizeExceededException e) {
         request.FILE_SIZE_EXCEEDED_ERROR = true
         new DefaultMultipartHttpServletRequest(request, new LinkedMultiValueMap(), [:], [:])
      }
      catch (SizeLimitExceededException e) {
         request.FILE_SIZE_EXCEEDED_ERROR = true
         new DefaultMultipartHttpServletRequest(request, new LinkedMultiValueMap(), [:], [:])
      }
   }
}

好的，谢谢你，这个错误被消除了，捕获正在工作。如果（request.FILE_SIZE_超过了_ERROR），我也需要在控制器中进行更改{但现在的问题是，由于参数丢失，我无法将用户扔回创建包。仅包含-->[操作：保存，格式：null，控制器：blaBlub]由于上载域是一个子域，因此创建视图需要父ID。知道如何至少保留父ID吗？您应该单独提出新问题。如您所愿，感谢您的支持！

class CustomMultipartResolver extends CommonsMultipartResolver {

   static final String FILE_SIZE_EXCEEDED_ERROR = 'fileSizeExceeded'

   MultipartHttpServletRequest resolveMultipart(HttpServletRequest request) {
      try {
         super.resolveMultipart request
      }
      catch (MaxUploadSizeExceededException e) {
         request.FILE_SIZE_EXCEEDED_ERROR = true
         new DefaultMultipartHttpServletRequest(request, new LinkedMultiValueMap(), [:], [:])
      }
      catch (SizeLimitExceededException e) {
         request.FILE_SIZE_EXCEEDED_ERROR = true
         new DefaultMultipartHttpServletRequest(request, new LinkedMultiValueMap(), [:], [:])
      }
   }
}
