email - 从 grails 发送邮件不起作用

Question

我在从 grails 发送邮件时遇到问题。向端口 587 添加一个例外，但没有任何帮助。仍然出现错误：

连接被拒绝：连接。堆栈跟踪如下：

应用程序.yml

mail:
         host: "smtp.gmail.com"
         port: 465
         username: "***@gmail.com"
         password: "***"
         props:
             mail.smtp.auth: "true"
             mail.smtp.socketFactory.port: "465"
             mail.smtp.socketFactory.class: "javax.net.ssl.SSLSocketFactory"
             mail.smtp.socketFactory.fallback: "true"

构建.gradle

runtime "org.grails.plugins:mail:2.0.0.RC4"

我也尝试过：运行时“org.grails.plugins:mail:2.0.0”运行时“org.grails.plugins:mail:2.0.0.RC6”也不起作用。

用户控制器.groovy

package grailsproject
class UserController {

    def mailService

    def form() {
    }

    def save() {

        def user = new Userr(params)
        user.validate()
        if(user.hasErrors())
        {
            user.errors.allErrors.each {
                println it
            }
            render (view:"/registrationForm/registrationForm", model: [user: user]);
        }else
        {
            user.save(flush: true)
            render(view: "user", model: [user: user]);
        }

        mailService.sendMail{
            to "***@gmail.com"
            from "***@gmail.com"
            subject "This is a test mail"
            body "Hello, This is a test mail, how are you?"
        }

    }


}

我不知道，我还应该检查什么...我也想知道为什么当我给那里的 gmail 主机时它会尝试连接本地主机？

你的 application.yml 应该是

grails:
     mail:
          host: "smtp.gmail.com"                                               
          port: 465                                                            
          username: "[e-mail]"                                       
          password: "Your_password"                                                 
          props:
              mail.smtp.auth: "true"                                           
              mail.smtp.socketFactory.port: "465"                              
              mail.smtp.socketFactory.class: "javax.net.ssl.SSLSocketFactory"
              mail.smtp.socketFactory.fallback: "false"

build.gradle 将是

compile "org.grails.plugins:mail:2.0.0.RC6"

UserController.groovy 应该是

package grailsproject

class UserController {

    def index() { }

    def send() {
        def multipartFile = request.getFile('attachment')

        sendMail {
            multipart true
            to params.address
            subject params.subject
            html params.body
            if(multipartFile && !multipartFile.empty) {
                File tmpFile = new File(System.getProperty("java.io.tmpdir") + System.getProperty("file.separator") + multipartFile.getOriginalFilename());
                multipartFile.transferTo(tmpFile);
                attach tmpFile
            }
        }
        flash.message = "Email Sent Successfully"
        redirect action:"index"
    }
}
