内容图文
我正在尝试使用Greenmail来测试我的localhost上的电子邮件功能.问题是我没有安装SMTP服务器,并且认为安装一个SMTP服务器过度.我的期望是应该有一个免费的库,允许我保持我的发送邮件代码相同,但不是真正发送电子邮件到SMTP服务器,发送到我的本地机器,以便我可以检索它们(为了单位)测试).
我曾经使用Grails开发时曾使用Greenmail,而且体验很棒.但我找不到类似于Spring Framework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有没有类似的服务？或者有没有更好的方法将测试电子邮件发送到localhost,我可以在哪里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：

解决方法:
您可以将Greenmail与任何Java程序一起使用,无论它是否使用Spring.你不需要任何Spring特定的东西.
它运行某种进程邮件服务器.
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将其邮件发送到由测试代码启动和完成的GreenMail-Server.
