grails mail:在localhost上工作的内联映像,而不是在测试环境中

Question

我将内联图像添加到localhost上的邮件中:

inline 'footerImage', 'image/jpg', new File('./web-app/images/mailAssets/suchebottomre.gif').readBytes()

哪个工作正常.当我部署到我的测试环境时,我收到此错误:

Class
java.io.FileNotFoundException
Message
cannot use ./web-app/images/mailAssets/alert_header_pre.png as an attachment as it does not exist

用这个日志:

   Line | Method
->>  331 | inline      in grails.plugin.mail.MailMessageBuilder
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

|     13 | contactUser in de.docinsider.web.NotifierService

|    615 | run . . . . in java.util.concurrent.ThreadPoolExecutor$Worker
^    722 | run         in java.lang.Thread

如何避免这种情况？

我还想要实现一个资源加载器:

import org.springframework.context.ResourceLoaderAware
import org.springframework.core.io.ResourceLoader

class SendController implements ResourceLoaderAware {
    @Autowired
    ResourceLoader resourceLoader
    def notifierService

    def index() { }
    def welcome = {
        notifierService.contactUser(params.username, params.email, params.message)
        render view:"/send/feedback", model:[name:params.username, message:params.message]
     }

     void setResourceLoader(ResourceLoader resourceLoader) {
        resourceLoader = resourceLoader
    }

}

这也行不通.

附:

 inline 'headerImage', 'image/jpg', resourceLoader.getResource('/images/mailAssets/header_top.png')
                inline 'footerImage', 'image/jpg', resourceLoader.getResource('/images/mailAssets/footer_bottom.gif')

在服务中.

Answer 1

我知道这是一个古老的线程,但我碰到了同样的问题,并发现该服务器不知道到图像中的真实路径,而是使用字符串作为真实路径" ./web-app/images/mailAssets/ alert_header_pre.png".

阅读这篇文章将帮助您获得真正的道路.代替:

inline 'footerImage', 'image/jpg', new File('./web-app/images/mailAssets/suchebottomre.gif').readBytes()

用这个:

inline 'footerImage', 'image/jpg', resourceLoader.getResource("/images/mailAssets/suchebottomre.gif").getFile()

您将需要import org.springframework.core.io.Resource or org.springframework.core.io.ResourceLoader和您的控制器实现implements org.springframework.context.ResourceLoaderAware并声明ResourceLoader resourceLoader
