Grails邮件插件：attach org.springframework.web.multipart.commons.commons multipartfile

我搞不懂怎么做附件。已安装插件“mail”，并且所讨论的文件是从表单上载（成功）的.csv文件

这项工作：

def f = request.getFile('uploadedFile')
//do a bunch of stuff with f and make bodyString
MailService.sendMail {
  to "myemail@secretplace.com"
  subject "subject"
  body bodyString
}

这并不是：

def f = request.getFile('uploadedFile')
//do a bunch of stuff with f and make bodyString
MailService.sendMail {
  multipart true
  to "myemail@secretplace.com"
  subject "subject"
  body bodyString
  attach "myfile.csv", f
}

哦，是的，错误是这样说的：

groovy.lang.MissingMethodException: No signature of method: my_project.MySweetController.attach() is applicable for argument types: (org.codehaus.groovy.runtime.GStringImpl, org.springframework.web.multipart.commons.CommonsMultipartFile) values: [Demo myfile.csv, org.springframework.web.multipart.commons.CommonsMultipartFile@73e2d16b]
Possible solutions: each(groovy.lang.Closure)

如果您使用的是0.9版或更高版本的邮件插件，那么以下应该可以使用

def f = request.getFile('uploadedFile')

//do a bunch of stuff with f and make bodyString
MailService.sendMail {
  multipart true
  to "myemail@secretplace.com"
  subject "subject"
  body bodyString
  attachBytes "Some-File-Name.csv", "text/csv", f.bytes
}

顺便说一句，您对邮件服务

MailService

的引用的名称是特殊的。如果您通过自动连接Springbean获得对该服务的引用，我希望它是

mailService

f。getBytes（）就是我现在拥有的。非常感谢。
