GreenMail邮件测试运用详解

一、Maven项目依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
      <version>3.2.3.RELEASE</version>
    </dependency>

              </configuration>
          </plugin>
      </plugins>
  </build>  
</project>

二、发送邮件接口：

package com.manxu.archetype.account.email;

import javax.security.auth.login.AccountException;

public interface AccountEmailService {
    
    void senMail(String to,String subject, String context) throws AccountException;
    
    
}

三、发送邮件接口实现类

package com.manxu.archetype.account.email;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import javax.security.auth.login.AccountException;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

public class AccountEmailServiceImp implements AccountEmailService{
    
    private JavaMailSender javaMailSender;
    private String systemEmail;
    
    @Override
    public void senMail(String to, String subject, String context) throws AccountException{
        try {
            MimeMessage my = javaMailSender.createMimeMessage();
            MimeMessageHelper help = new MimeMessageHelper(my);
            help.setFrom(systemEmail);
            help.setTo(to);
            help.setSubject(subject);
            help.setText(context);
            javaMailSender.send(my);            
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public JavaMailSender getJavaMailSender() {
        return javaMailSender;
    }

    public void setJavaMailSender(JavaMailSender javaMailSender) {
        this.javaMailSender = javaMailSender;
    }

    public String getSystemEmail() {
        return systemEmail;
    }

    public void setSystemEmail(String systemEmail) {
        this.systemEmail = systemEmail;
    }
}

四、配置文件

#email.protocol=smtps
#email.host=smtp.163.com
#email.port=465
#email.username=[e-mail]
#email.password=zhaojuan1
#email.auth=true
#email.systemEmail=[e-mail]

## greenmail 测试不需要服务器，可以把自身当前服务器，并提供虚拟用户，如本例发件 [e-mail],收件[e-mail]

email.protocol=smtp
email.host=localhost
email.port=25
email.username=[e-mail]
email.password=123456
email.auth=true
email.systemEmail=[e-mail]

五、测试类

package com.manxu.archetype.account.email;

import javax.mail.Message;
import javax.security.auth.login.AccountException;
import junit.framework.Assert;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.icegreen.greenmail.util.GreenMail;
import com.icegreen.greenmail.util.ServerSetup;
import com.icegreen.greenmail.util.ServerSetupTest;

public class AccountEmailServiceTest {
    
    private GreenMail greenMail;
    
    @Before
    public void startMailServer(){
        greenMail = new GreenMail(ServerSetup.SMTP);
        greenMail.setUser("[e-mail]", "123456");
        greenMail.start();
    }
    
    @Test
    public void testSendMail() throws Exception{
        ApplicationContext ctx = new ClassPathXmlApplicationContext("account-email.xml");
        AccountEmailService service = (AccountEmailService) ctx.getBean("accountEmailService");
        
        String subject = "text subject";
        String htmlText = "<h3>text</h3>";
        service.senMail("[e-mail]", subject, htmlText);
        greenMail.waitForIncomingEmail(2000, 1);
        Message[] msgs = greenMail.getReceivedMessages();
        Assert.assertEquals(1, msgs.length);
        Assert.assertEquals(subject, msgs[0].getSubject());
    }
    
    @After
    public void stopMailServer(){
        greenMail.stop();
    }   
}
