如何捕获"org.springframework.web.multipart.MultipartException"在Grails 3中 [英] How to catch "org.springframework.web.multipart.MultipartException" in Grails 3

问题描述

我很难捕捉到错误:org.springframework.web.multipart.MultipartException

我有以下代码:

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

另外要处理文件的发布，我需要执行以下操作:

Additionally to handle the post of the file I have this action:

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

我已经在"application.yml"目录中获得了这些设置.文件以强制错误:

I've got these settings in the "application.yml" file to force the error:

controllers:
    upload:
        maxFileSize: 100
        maxRequestSize: 100

因此，我可以可靠地重新创建异常，但是在浏览器显示出可怕的视图之前，我无法捕获该异常:

So I can reliably recreate the exception, but I can't catch it before the browser shows a horrible view:

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.仅在上传操作中使用try/catch会失败.

Please tell me how to catch this error in Grails. Just using a try/catch in the upload action fails miserably.

应评论者的要求添加了堆栈跟踪:

推荐答案

您可以在堆栈跟踪中找到:

You can find in a stacktrace:

该请求被拒绝，因为其大小(318635)超出了 配置的最大值(100000)

the request was rejected because its size (318635) exceeds the configured maximum (100000)

并在您的代码中:

controllers:
    upload:
        maxFileSize: 100
        maxRequestSize: 100

您应该超过maxFileSize，但是如果您要处理异常，请检查此解决方案.恕我直言，更清洁的解决方案将是您自己的before filter或interceptor的实现.

you should exceed maxFileSize, but if you want to handle exception check this solution. IMHO cleaner solution would be implementation of your own before filter or interceptor.
