Question

当我上传大文件时，我想捕获异常SizeLimitExceededException。但是，我在控制器中创建了一个方法来捕获此异常，但是他返回了：

Error 500: Internal Server Error
URI
/user/uploadProfileImage
Class
org.apache.tomcat.util.http.fileupload
.FileUploadBase$SizeLimitExceededException
Message
Could not parse multipart servlet request; nested exception is 
java.lang.IllegalStateException: 
org.apache.tomcat.util.http.fileupload
.FileUploadBase$SizeLimitExceededException: the request was rejected because its size (310380) exceeds the configured maximum (128000)
Caused by
the request was rejected because its size (310380) exceeds the configured maximum (128000)

捕获异常的方法：

def handleSizeLimitExceededException(FileUploadBase.SizeLimitExceededException ex){
     render(['error':true, message:ex.getMessage()] as JSON)
}

我的控制器：

class UserController {
...
    def uploadProfileImage(ProfileImageCommand cmd) {
        if (cmd.hasErrors()) {
                //respond(cmd, model: [user: cmd], view: 'create')
                response.status = 500
                render(['error':true, message:cmd.getErrors()] as JSON)
            }

        String filename = uploadFileService.uploadFileInTemp(cmd, relativePathTmp)

        Locale locale = request.locale
        //flash.message = crudMessageService.message(CRUD.UPDATE, domainName(locale), pointOfInterest.id, locale)
        render(['filename':filename, 'url': uploadFileService.getUrl(filename, relativePathTmp)] as JSON)
    }

    def handleSizeLimitExceededException(FileUploadBase.SizeLimitExceededException ex){
        render(['error':true, message:ex.getMessage()] as JSON)
    }
}

我的可验证者：

class ProfileImageCommand implements Validateable {
    MultipartFile imageFile

    static constraints = {
        imageFile  validator: { val, obj ->
            if ( val == null ) {
                return false
            }
            if ( val.empty ) {
                return false
            }

            ['jpeg', 'jpg', 'png'].any { extension ->
                val.originalFilename?.toLowerCase()?.endsWith(extension)
            }
        }
    }
}

谢谢您的帮助！

您没有提到Grails版本。我假设它的3 +

在application.yml中，您可以使用这些设置来设置要上传的文件的最大大小。

grails:
controllers:
        upload:
            maxFileSize: 20000000
            maxRequestSize: 20000000

此示例将请求和文件大小都设置为20MB。您可以根据需要进行调整。
