spring - Grails邮件插件:附加org.springframework.web.multipart.commons.CommonsMultipartFile

Question

我不知道该怎么做附件。已安装插件“邮件”，相关文件是从表单上载(成功)的.csv文件。

这有效:

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，错误说明了这一点:

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)

Answer 1

如果您使用的是0.9版或更高版本的邮件插件，则应该可以执行以下操作

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的引用名称很特殊。如果您通过 Autowiring Spring bean获得对该服务的引用，我希望它是mailService
