Java 如何在greenmail for CI Server中随机化端口

使用JUnit和Greenmail，我希望获得Greenmail使用的随机端口，而不是默认端口或带有偏移量的端口。 为此，我尝试使用ServerSocket0获得一个随机端口，而greenmail的开始工作与设计相符。 但是，当我在测试期间尝试发送邮件时，会出现一个异常，即无法连接到端口3025，这是greenmail的默认值

包装de.itout.test.tdd.tdd.mocking； 导入com.icegreen.greenmail.configuration.*； 导入com.icegreen.greenmail.junit.*； 导入com.icegreen.greenmail.user.*； 导入com.icegreen.greenmail.util.*； 导入java.io.*； 导入java.net。*； 导入java.util.*； 导入javax.mail.*； 导入javax.mail.internet.*； 导入org.junit.*； 导入静态org.junit.Assert.*； 公共类邮件测试 { 绿邮绿邮SMTPIMAP； 公开邮件测试 { } @以前 公共void安装程序引发IOException { ServerSocket ssSMTP=新的ServerSocket0； ServerSocket ssIMAP=新的ServerSocket0； int randomPortSMTP=ssSMTP.getLocalPort； int randomPortIMAP=ssIMAP.getLocalPort； ssSMTP.close； ssIMAP.close； ServerSetup smtpSetup=newserversetuprandomportsmtp，null，ServerSetup.PROTOCOL\u SMTP； ServerSetup imapSetup=newserversetuprandomportimap，null，ServerSetup.PROTOCOL\u IMAP； greenMailSMTPIMAP=new GreenMailnew ServerSetup[]{smtpSetup，imapssetup}； greenMailSMTPIMAP.start； } @之后 公共空间拆除 { greenMailSMTPIMAP.stop； } @试验 public void testSend抛出MessaginException { 格林梅鲁蒂尔。sendTextEmailTestto@localhost.com, from@localhost.com, 一些主题，一些主体；//-将发送代码放在此处 AsserteQualsome主体，GreenMailUtil.getBodygreenMailSMTPIMAP.getReceivedMessages[0]； } @试验 public void testReceive抛出消息异常 { GreenMailUser用户=greenMailSMTPIMAP。setUserto@localhost.com，登录id，密码； user.deliverCreateMememessage；//您可以创建更复杂的消息。。。 格林梅鲁蒂尔。sendTextEmailTestto@localhost.com, from@localhost.com, 主题、正文；/…或使用默认消息 assertEquals2，greenMailSMTPIMAP.getReceivedMessages.length；//-将POP3或IMAP检索代码放在此处 } 私有mimessage createmimessage { 返回GreenMailUtil。createTextEmailto@localhost.com, from@localhost.com，主题，正文，greenMailSMTPIMAP.getImap.getServerSetup； } }

---

只需将服务器设置传递给方法GreenMailUtil.sendTextEmail…，ServerSetup 不要使用标准的测试方法

@试验 public void testSend抛出MessaginException { 格林梅鲁蒂尔。sendTextEmailto@localhost.com, from@localhost.com, 一些主题，一些正文，greenMail.getSmtp.getServerSetup；//-将发送代码放在此处 AsserteQualsome主体，GreenMailUtil.getBodygreenMail.getReceivedMessages[0]； }
