【英文标题】：Grails 4: Mail plugin fails to read 'password' property when running on Elastic Beanstalk

【问题描述】：

我的 Grails 4 应用程序在本地运行良好，但在 Elastic Beanstalk 中运行时无法发送电子邮件。我正在使用嵌入式（非外部）Tomcat 服务器在 Java 11 平台上使用可运行的 WAR 文件。

我通过GRAILS_MAIL_PASSWORD 环境变量在外部设置grails.mail.password 属性。

我正在检查BootStrap.groovy 和EmailsService 中的配置值，并且该值设置正确。

引导带

class BootStrap 

    GrailsApplication grailsApplication

    def init =  servletContext ->
        String config = "\n"
        grailsApplication.config.each 
            config += " --> $it.key : $grailsApplication.config.getProperty(it.key)\n"
        
        log.info(config)

电子邮件服务

class EmailService 

    @Value('$cloudcard.email.doNotSend')
    boolean doNotSend

    @Value('$grails.mail.username')
    String grailsMailUsername

    @Value('$grails.mail.password')
    String grailsMailPassword

    @PostConstruct
    void init() 
        log.info("grailsMailUsername: $grailsMailUsername.take(2)****$grailsMailUsername.reverse().take(2).reverse()")
        log.info("grailsMailPassword: $grailsMailPassword.take(4)****$grailsMailPassword.reverse().take(4).reverse()")
    

邮件服务日志输出

但是……

...如果我将用户名和密码硬编码到application.groovy，一切正常，我会在收件箱中收到电子邮件。我不确定这是否重要，但这是我在application.groovy 中配置的唯一内容之一。几乎所有其他内容都在 application.yml 中。

您知道为什么 Grails 邮件插件可能会忽略我的外部配置吗？

【参考方案1】：

作为一种解决方法，我使用外部 Tomcat 容器平台（Amazon Linux 2；Tomcat 8.5；Corretto Java 11）重新部署了相同的应用程序，并且该应用程序现在尊重环境变量。
