Grails 2.4.3下使用Asynchronous Mail Plugin
第一步：安装
在buildconfig中添加
compile ":asynchronous-mail:1.1"
然后ide执行compile命令安装插件
第二步：设置
执行
grails install-asynchronous-mail-config
会在conf目录生成asynchronousMailConfig文件内容如下：
asynchronous.mail.default.attempt.interval=300000l //5分钟，发送尝试的间隔时间，单位毫秒 asynchronous.mail.default.max.attempts.count=1 //每个消息发送尝试的最大次数 asynchronous.mail.send.repeat.interval=60000l //1分钟，重复启动发送任务的时间间隔，单位毫秒 asynchronous.mail.expired.collector.repeat.interval=607000l //重复启动收集过期任务（如果发送时间过期了，就给消息打上过期的标记） asynchronous.mail.messages.at.once=100 //一次能够发送的最大消息个数 asynchronous.mail.send.immediately=true //如果为true，会在消息创建后立刻运行发送任务。 asynchronous.mail.override=false//是否允许重写 asynchronous.mail.clear.after.sent=false //发送后清除内容记录 asynchronous.mail.disable=false //如果为true，则邮件发送系统停止工作 asynchronous.mail.useFlushOnSave=trueasynchronous.mail.persistence.provider='hibernate4' // Possible values are 'hibernate', 'hibernate4', 'mongodb' //选择是使用数据对象关系框架 asynchronous.mail.gparsPoolSize=1 //邮件池大小 asynchronous.mail.newSessionOnImmediateSend=false创建异步发送邮件的视图和控制器
create-asynchronous-mail-controller --package=com.example通过它可以查看邮件的发送情况
第三步:配置
在conf/Config.groovy中增加邮件服务
grails {
mail {
host = "smtp.gmail.com"
port = 465
username = "[email protected]"
password = "yst3330800"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
} }
修改DataSource.groovy文件配置数据库,完成后在数据库中新建数据库.(这一步必须做,用默认数据库会报错)
第四步:开始使用
新建控制器
grails create-controller com.xtcanyin.Mail 然后修改控制内容如下:
package com.xtcanyin
class MailController {
def successService //所使用的服务类,类名第一个字母要小写
def index() { }
def send ={
successService.serviceMethod(params.name,params.email) //服务类名.方法名
render "email sent!"
}
建立Grails服务类
grails create-service com.xtcanyin.success 并修改如下:
package com.xtcanyin
import grails.transaction.Transactional
import grails.plugin.asyncmail.AsynchronousMailService //引入异步发送插件
@Transactional //这个一定要有,否则一样报错
class SuccessService {
boolean transactional = false
AsynchronousMailService asynchronousMailService
//AsynchronousMailService asyncMailService
def serviceMethod(name,eamil) {
asynchronousMailService.sendAsynchronousMail {
// Mail parameters
from 'admin<[email protected]>'
to eamil
subject 'Test';
body "thank you ${name} for grails-mail"
html '<body><u>Testup</u></body>';
//attachBytes 'test.txt', 'text/plain', byteBuffer;
// Additional asynchronous parameters (optional)
beginDate new Date(System.currentTimeMillis()+60000) // Starts after one minute, default current date
endDate new Date(System.currentTimeMillis()+3600000) // Must be sent in one hour, default infinity
maxAttemptsCount 3; // Max 3 attempts to send, default 1
attemptInterval 300000; // Minimum five minutes between attempts, default 300000 ms
delete true; // Marks the message for deleting after sent
immediate true; // Run the send job after the message was created
priority 10; // If priority is greater then message will be sent faster
}
}
}
增加index.gsp和send.gsp两个视图
index.gsp

Thank you ${name} for using grails-asynchronous-mail plugin from a service,
Rendered content from a GSP!
