自动化测试过程中，需要将测试结果以固定模板发送邮件的方式进行邮件发送。以下详细介绍配置过程。
1、在pom.xml文件中引入需要的包
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>javax.mail-api</artifactId>
<version>1.5.5</version>
</dependency>
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker</artifactId>
<version>2.3.23</version>
</dependency>
2、在main/resources下新增配置文件spring-mail.xml
注意这里需要引入的配置：
1）、FreeMarker模板的配置
2）、javamail邮件发送的配置
3）、SimpleMailMessage的参数配置
4）、邮件服务实现类service的注入
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<!-- 引入mail配置文件 -->
<context:property-placeholder location="classpath:mail.properties"/>
<!--FreeMarker模板 -->
<bean id="freeMarkerConfigurer"
class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath" value="classpath:freemaker/" />
<property name="freemarkerSettings">
<props>
<prop key="locale">zh_CN</prop>
<prop key="default_encoding">UTF-8</prop>
</props>
</property>
</bean>
<bean id="emailService" class="com.atguigu.crud.service.EmailService" >
<property name="mailSender" ref="mailSender"></property>
<property name="freeMarkerConfigurer" ref="freeMarkerConfigurer"></property>
<property name="simpleMailMessage" ref="simpleMailMessage"></property>
</bean>
<!--邮件发送 -->
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="defaultEncoding" value="UTF-8"></property>
<property name="host" value="${mail.host}" />
<property name="username" value="${mail.username}" />
<property name="password" value="${mail.password}" />
<property name="javaMailProperties">
<props>
<prop key="classic_compatible">true</prop>
<prop key="mail.transport.protocol">smtp</prop>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.smtp.timeout">25000</prop>
</props>
</property>
</bean>
<bean id="simpleMailMessage" class="org.springframework.mail.SimpleMailMessage">
<property name="from" value="${mail.username}" />
<property name="subject" value="${mail.title}" />
<property name="to" value="${mail.touser}" />
<property name="cc" value="${mail.cc}"/>
</bean>
</beans>
3、创建mail.properties文件，便宜上述配置中的参数化调用
mail.host=smtp.163.com
mail.username=***@163.com
mail.password=***
mail.title=error
mail.touser=***@qq.com,***@126.com
mail.cc=***@163.com
4、在项目的resources的freemaker的包下新增邮件发送模板 welcome.ftl
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf8">
</head>
<body>
恭喜您成功注册！<br/>
您的用户名为：<font color='red' size='20'>${name}</font>,
您的ID为：<font color='red' size='20'>${id}</font> <img src='cid:welcome'/>
</body>
5、新增EmailService类，用于邮件发送处理
package com.atguigu.crud.service;
import com.atguigu.crud.bean.User;
import com.sun.xml.internal.messaging.saaj.packaging.mime.internet.MimeUtility;
import freemarker.template.Template;
import freemarker.template.TemplateException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
import org.springframework.stereotype.Service;
import org.springframework.ui.freemarker.FreeMarkerTemplateUtils;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;
import javax.mail.internet.MimeMessage;
import java.io.File;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
@Service
public class EmailService {
private JavaMailSender mailSender;
private FreeMarkerConfigurer freeMarkerConfigurer;
private SimpleMailMessage simpleMailMessage;
public void setMailSender(JavaMailSender mailSender) {
this.mailSender = mailSender;
}
public void setFreeMarkerConfigurer(FreeMarkerConfigurer freeMarkerConfigurer) {
this.freeMarkerConfigurer = freeMarkerConfigurer;
}
public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
this.simpleMailMessage = simpleMailMessage;
}
//通过freemarker模板构造邮件内容
private String getMailText(User employee) throws IOException, TemplateException {
// 通过指定模板名获取FreeMarker模板实例
Template template = freeMarkerConfigurer.getConfiguration().getTemplate("welcome.ftl");
// FreeMarker通过Map传递动态数据
Map<String,Object> map = new HashMap<String,Object>();
// 注意动态数据的key和模板标签中指定的属性相匹配
map.put("name",employee.getUsername());
map.put("id",employee.getUserid());
// 解析模板并替换动态数据，最终content将替换模板文件中的${content}标签。
String htmlTxt = FreeMarkerTemplateUtils.processTemplateIntoString(template,map);
return htmlTxt;
}
public void sendMail(User employee, String filepath1, String wordPath2) throws Exception {
MimeMessage message = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message,true,"utf-8");
helper.setFrom(simpleMailMessage.getFrom());
helper.setTo(simpleMailMessage.getTo());
helper.setCc(simpleMailMessage.getCc());
helper.setSubject(MimeUtility.encodeText(simpleMailMessage.getSubject()));
helper.setText(getMailText(employee),true);
helper.addInline("welcome",new File(filepath1));
mailSender.send(message);
System.out.println("邮件发送成功...");
}
}
6、上述邮件实现类中用到的User实体类内容：
package com.atguigu.crud.bean;
public class User{
private String userid;
private String username;
public String getUserid() {
return userid;
}
public void setUserid(String userid) {
this.userid = userid == null ? null : userid.trim();
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username == null ? null : username.trim();
}
7、测试类，使用junit测试发送邮件
package com.atguigu.crud.test;
import com.atguigu.crud.bean.User;
import com.atguigu.crud.service.EmailService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class EmailSendTest {
@Test
public void testSendMail() throws Exception {
ApplicationContext context = new ClassPathXmlApplicationContext("spring-mail.xml");
EmailService emailService = (EmailService) context.getBean("emailService");
User user = new User();
user.setUsername("sundy");
user.setUserid("10000");
String path1="./src/main/resources/welcome.gif";
String path2="./src/main/resources/welcome.docx";
emailService.sendMail(user,path1,path2);
}
}
测试结果：

在测试过程中遇到问题：
使用javamail进行用户注册并给用户发一封邮件实现用户激活功能时，在所有代码都没有问题时仍然没有办法成功发送邮件并且提示错误com.sun.mail.smtp.SMTPSendFailedException: 554 DT:SPM 163 smtp11,D8CowAAX_C3G_FBZ1RimNQ--.35430S2 1498479815,please see http://mail.163.com/help/help_spam_16.htm?ip=119.xx.xx.xx&hostid=smtp11&time=1498479815，然后去点链接进网易查看了一下，官方给出的是【•554 DT:SPM 发送的邮件内容包含了未被许可的信息，或被系统识别为垃圾邮件。请检查是否有用户发送病毒或者垃圾邮件；】，没什么用。在网上查了很长时间，有很多都说试一下发送正常一点的内容，试了很多遍也还是报错。
解决方案：
发送给收信人之前给自己抄送一份即可。
helper.setCc(simpleMailMessage.getCc());
