Question

我很难抓住错误：

org.springframework.web.multipart.MultipartException

我有以下代码：

final class UploadTextCommand  {
   MultipartFile contents
   static constraints = {
   }
}

另外，为了处理文件的帖子，我有这个动作：

def upload = { UploadTextCommand -> 
   ...code...
}

我在“application.yml”文件中有这些设置来强制错误：

controllers:
    upload:
        maxFileSize: 100
        maxRequestSize: 100

所以我可以可靠地重新创建异常，但是在浏览器显示一个可怕的视图之前我无法捕获它：

HTTP Status 500 - Request processing failed; 
nested exception is org.springframework.web.multipart.MultipartException

请告诉我如何在Grails中捕获此错误。只需在上传操作中使用try / catch就会失败。

根据评论者的要求添加了堆栈跟踪：

您可以在堆栈跟踪中找到：

请求被拒绝，因为它的大小（318635）超过了配置最大值（100000）

并在您的代码中：

controllers:
    upload:
        maxFileSize: 100
        maxRequestSize: 100

您应该超过maxFileSize，但是如果您想要处理异常check this solution。恕我直言清洁解决方案将实现您自己的before filter或interceptor。
