java - Grails:从是否发送邮件的mailService获得返回

Question

这是我最近使用的代码

if(!toAddress.equalsIgnoreCase("")){
            mailService.sendMail {
                to toAddress
                subject "This is a test mail"
                body "Hello, This is a test mail."
            }
}

但我不知道如何从sendMail获得返回结果

Answer 1

我在插件tests中看到，如果失败，该方法将引发GrailsMailException。
因此，您可以使用try-catch:

try {
   mailService.sendMail {
       to toAddress
       subject "This is a test mail"
       body "Hello, This is a test mail."
    }
} catch(GrailsMailException e) {
    log.warn('Message failed with exception', e) 
}
