邮件服务测试GreenMail

GreenMail是开源的邮件服务测试套件
在POM中定义项目依赖：

    <!--实现发送必须的类库-->
    <dependency>
      <groupId>javax.mail</groupId>
      <artifactId>mail</artifactId>
      <version>1.4.7</version>
    </dependency>

    <dependency>
      <groupId>com.icegreen</groupId>
      <artifactId>greenmail</artifactId>
      <version>1.3.1b</version>
    </dependency>

在测试代码中的片段

        try{
            //msg对应将要发送的邮件
            MimeMessage msg=javaMailSender.createMimeMessage();
            //msgHelp帮助设置邮件信息
            MimeMessageHelper msgHelp=new MimeMessageHelper(msg);

            //设置发件人、收件人和邮件主题
            msgHelp.setFrom(systemEmail);
            msgHelp.setTo(to);
            msgHelp.setSubject(subject);
            //true表示邮件内容为html格式
            msgHelp.setText(htmlText,true);

            javaMailSender.send(msg);
        }catch (Exception e){
            e.printStackTrace();
        }

将邮件服务器的相关配置分离到外部的properties中，

email.protocol=smtp
email.host=smtp.163.com
email.port=465
email.username=[e-mail]
email.password=your_password
email.auth=zsfeng
email.systemEmail=[e-mail]

对GreenMail的使用：
在执行测试任务之前，要启动邮件服务器：

    private GreenMail greenMail;
    @Before
    public  void startMailService(){
        greenMail=new GreenMail(ServerSetup.SMTP);
        greenMail.setUser("[e-mail]","your_password");
        greenMail.start();
    }

在测试完成之后，要关闭GreenMail:

@After
    public  void stopMailService(){
        greenMail.stop();
    }

测试环境设置的properties不同：

email.protocol=smtp
email.host=localhost
email.port=25
email.username=[e-mail]
email.password=your_password
email.auth=zsfeng
email.systemEmail=[e-mail]
