Grails 3邮件插件无法正常工作 [英] Grails 3 mail plugin not working

问题描述

使用Grails 3无法获得mailService对象的实例，DI不起作用：

build.gradle

  compileorg.grails.plugins：mail：1.0.7
 testCompileorg.grails.plugins：mail：1.0.7
  

application.groovy

  environments {
 development {
 //grails.logging.jul.usebridge = true 
 grails.plugin.springsecurity.debug.useFilter = true 
 grails {
 mail {
 host =main.mydomain.com
 port = 25 
 username =login
 password =password
 props = [mail.smtp .auth：true] 
 
} 
} 
 grails.mail.default.from =[e-mail]
 
} 
生产{
 grails.logging.jul.usebridge = false 
} 
} 
  

testController：

  import groovy.xml.M arkupBuilder 
 import org.slf4j.Logger 
 import org.slf4j.LoggerFactory 
 import org.springframework.security.access.annotation.Secured 
 
 @Secured（[ hasRole（'PERM_LOGIN'）]）$ b $ class TestLogController {
 
 def Logger logger = LoggerFactory.getLogger（this.getClass（））
 def mailService 
 
 def index（）{
 
 logger.info（Hello）; 
 
 mailService.sendMail {
到[e-mail]
主题Hello Fred
文字你好吗？ 
 
 
 
 $ $ $ 
 $ b 
发生以下错误： / p> 
 
 
 引起NullPointerException：无法调用null对象上的sendMail（）方法
  - >> 18 |在TestLogController.groovy中的索引
  
因此，mailService没有被正确注入到cotroller类或集成测试中：
 导入grails.test.mixin.integration.Integration 
导入grails.util.Holders 
导入组织。 slf4j.Logger 
 import org.slf4j.LoggerFactory 
 import org.springframework.context.ApplicationContext 
 import spock.lang.Shared 
 import spock.lang.Specification 
 
 @Integration 
 class SendMailSpec extends Specification {
 
 @Shared Logger logger 
 @Shared def mailService 
 
 def setup（）{
 logger = LoggerFactory.getLogger（this.getClass（））
 ApplicationContext ctx = Holders.grailsApplication.mainContext 
 mailService = ctx.getBean（mailService）; 
 
 
 $ b def cleanup（）{
} 
 
 voidtest mailService is not null（）{
期望：
 mailService！= null 
} 
 
 voidtest send mail（）{
 expect：mail send
 mailService.sendMail { 
到[e-mail]
主题Hello Fred
文字你好吗？ 
} 
} 
} 
  
什么是问题？  
 
 
更新：这是错误的邮件插件版本，这个工作正常： 
 
 
  compileorg.grails.plugins：mail：2.0.0.RC2
  
 
 
解决
  compile'org 
这是当前版本.grails.plugins：mail：2.0.0.RC6'
  
这里是主插件的链接（我不知道为什么谷歌只显示旧版本）：
 
  https： //grails.org/plugins.html#plugin/mail  
我希望这可以帮助别人
 
Using Grails 3 it's impossible to get an instance of mailService object, DI is not working:

build.gradle
compile "org.grails.plugins:mail:1.0.7"
testCompile "org.grails.plugins:mail:1.0.7"
application.groovy
environments {
    development {
     //grails.logging.jul.usebridge = true
     grails.plugin.springsecurity.debug.useFilter = true
     grails {
        mail {
            host = "main.mydomain.com"
            port = 25
            username = "login"
            password = "password"
            props = ["mail.smtp.auth":"true"]

        }
    }
    grails.mail.default.from="[e-mail]"

    }
    production {
        grails.logging.jul.usebridge = false
    }
}
testController:
import groovy.xml.MarkupBuilder
import org.slf4j.Logger
import org.slf4j.LoggerFactory
import org.springframework.security.access.annotation.Secured

@Secured(["hasRole('PERM_LOGIN')"])
class TestLogController {

    def Logger logger = LoggerFactory.getLogger(this.getClass())
    def mailService

    def index() {

        logger.info("Hello");

        mailService.sendMail {
           to "[e-mail]"
           subject "Hello Fred"
           text "How are you?"
        }       
    }
}
The following error occurs:
Caused by NullPointerException: Cannot invoke method sendMail() on null    object
->>   18 | index                    in TestLogController.groovy
So mailService has not been injected properly to cotroller class or to integration test:
import grails.test.mixin.integration.Integration
import grails.util.Holders
import org.slf4j.Logger
import org.slf4j.LoggerFactory
import org.springframework.context.ApplicationContext
import spock.lang.Shared
import spock.lang.Specification

@Integration
class SendMailSpec extends Specification {

    @Shared Logger logger
    @Shared def mailService

    def setup() {
        logger = LoggerFactory.getLogger(this.getClass())
        ApplicationContext ctx = Holders.grailsApplication.mainContext
        mailService = ctx.getBean("mailService");

    }

    def cleanup() {
    }

    void "test mailService is not null"() {
       expect:
       mailService !=null
    }

    void "test send mail"() {
      expect:"mail send"
       mailService.sendMail {
          to "[e-mail]"
          subject "Hello Fred"
          text "How are you?"
       }
    }
}
What is a problem ??

UPDATE: It was wrong mail plugin version, this one works fine:
compile "org.grails.plugins:mail:2.0.0.RC2"

解决方案
here's the current version (at the moment of writing this) to install :  
compile 'org.grails.plugins:mail:2.0.0.RC6'
Here's the link to the main plugin (I don't know why google shows only the old versions) :

https://grails.org/plugins.html#plugin/mail 
I hope this helps someone
