我正在尝试使用 Greenmail 在我的本地主机上对电子邮件功能进行单元测试。问题是我还没有安装 SMTP 服务器，并且觉得安装一个过于杀戮。我的期望是应该有一个免费库允许我保持发送邮件代码相同，但不是真正将电子邮件发送到 SMTP 服务器，而是将其发送到我的本地计算机以便我可以检索它们（为了单位测试）。

我曾经在用Grails开发的时候用过Greenmail，体验很棒。但是我找不到 Spring Framework 类似的东西。在Greenmail页面中，它说有一个与 JBoss 捆绑在一起的模拟 SMTP 服务器。但我不想运行 JBoss，因为目前我的 Web 应用程序正在 Tomcat 上运行。

Tomcat 已经有类似的服务了吗？或者有没有更好的方法将测试电子邮件发送到本地主机，在那里我可以检索发送的电子邮件？

更新：

我尝试使用 Ralph 的方法，但它仍然产生相同的异常：

您可以将Greenmail与任何 Java 程序一起使用，无论它是否使用 Spring。您不需要任何 Spring 特定的东西。

它运行某种进程中的邮件服务器。

import com.icegreen.greenmail.util.GreenMail;
import com.icegreen.greenmail.util.GreenMailUtil;
import com.icegreen.greenmail.util.ServerSetupTest; ...

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("ApplicationContext-Greenmail.xml")
public class EmailServiceIntegrationTest {

    /** Class under test */
    @Resource
    private EmailService emailService;

    private GreenMail greenMail;

    @Before
    public void startMailServer() {
        greenMail = new GreenMail(ServerSetupTest.SMTP);
        greenMail.start();
    }

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

    @Test
    public void testPledgeReminder()
                throws InterruptedException, MessagingException {

        String mailText = "Hallo World";
        String mailSubject = "Hallo";
        String mailTo = "test@excaple.com";

        /** when: sending a mail */
        emailService.send(mailSubject, mailTo, mailText);

        assertTrue(greenMail.waitForIncomingEmail(5000, 1));
        Message[] messages = greenMail.getReceivedMessages();
        assertEquals(1, messages.length);
        assertEquals(mailText, messages[0].getSubject());       
        String body = GreenMailUtil.getBody(messages[0]).replaceAll("=\r?\n", "");
        assertEquals(mailText, body);       
    }

}

重要：使用端口 3025

<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="javaMailProperties">
        <util:properties>
            <prop key="mail.debug">false</prop>
            <prop key="mail.transport.protocol">smtp</prop>
            <prop key="mail.smtp.port">3025</prop>
            <prop key="mail.smtp.auth">true</prop>
            <prop key="mail.smtp.user">test@mail.extern</prop>
            <prop key="mail.smtp.host">localhost</prop>
            <prop key="mail.smtp.from">test@mail.extern</prop>
        </util:properties>
    </property>
    <property name="username" value="test"/>
    <property name="password" value="xxx"/>
    <property name="defaultEncoding" value="utf8" />
</bean>

然后此配置将配置 Spring JavaMailSender 以将其邮件发送到由测试代码启动和完成的 GreenMail-Server。

编辑（2017 年 11 月）：

Dumbster 链接已失效，在 github 上有一个分支https://github.com/kirviq/dumbster

看看 Dumbster - 我将它用于我所有的单元测试，因为它允许我对实际发送的电子邮件进行断言。

似乎有人曾经提出过这样的整合： http: //sourceforge.net/mailarchive/forum.php ?thread_name=45DEB9E3.6090608%40consol.de&forum_name=greenmail-developers

不知道还能不能用。。。

在测试中做这样的事情spring对我来说很好：

ServerSetupTest.setPortOffset(<SOME_CUSTOM_PORT>);
testEmailServer = new GreenMail();
testEmailServer.start();

该类背后的主要思想ServerSetupTest是创建一个ServerSetup具有用户定义的端口偏移量的测试。有关更多详细信息，请参阅文档。

尝试像这样手动设置 GreenMail 服务器的端口：

 @Before
public void startMailServer()
    throws Exception
{
    ServerSetup setup = new ServerSetup(3025,"localhost","smtp");
    greenMail = new GreenMail(setup);
    greenMail.start();
}

然后设置你的邮件发件人的端口和上面一样，注意协议/主机/端口：

email.protocol=smtp
email.host=localhost
email.port=3025
email.username=to@localhost.com
email.password=to@localhost.com
email.auth=true
email.systemEmail=from@localhost.com

使用 bean 配置：

<bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="protocol" value="${email.protocol}" />
    <property name="host" value="${email.host}" />
    <property name="port" value="${email.port}" />
    <property name="username" value="${email.username}" />
    <property name="password" value="${email.password}" />
    <property name="javaMailProperties">
        <props>
            <prop key="mail.${email.protocol}.auth">${email.auth}</prop>
        </props>
    </property>
</bean>
