事务结束后执行任务- Grails

import grails.async.Promise

class EmailTask {
    static transactional = false // 禁用事务

    static def sendEmail(String recipient, String subject, String content) {
        // 发送邮件的逻辑
    }
}

import grails.transaction.Transactional

@Transactional
class MyService {
    def emailTask

    def doSomething() {
        // 业务逻辑

        withTransaction { status ->
            // 异步执行发送邮件任务
            def promise = emailTask.task {
                EmailTask.sendEmail("recipient@example.com", "Hello", "This is a test email.")
            }

            // 处理异步任务结果
            promise.onComplete { result ->
                if (result instanceof Throwable) {
                    // 处理任务执行异常
                } else {
                    // 处理任务执行成功
                }
            }
        }

        // 继续执行其他业务逻辑
    }
}
