spring基于javax.mail封装了一套用于发送电子邮件的api，位于org.springframework.mail包下，下面将介绍下发送普通文本邮件和基于thymeleaf模版的邮件。
普通邮件
导入javax.mail依赖
<!-- ...... -->
<!-- 省略spring依赖 -->
<dependency>
<groupid>com.sun.mail</groupid>
<artifactid>javax.mail</artifactid>
<version>1.6.2</version>
</dependency>
spring配置类
@propertysource(value="classpath:mail.properties")
@configuration
public class springconfig {
@autowired
environment environment;
/**
* spring邮件配置
*/
@bean
public javamailsenderimpl javamailsenderimpl(){
javamailsenderimpl javamailsenderimpl = new javamailsenderimpl();
javamailsenderimpl.sethost(environment.getproperty("mail.host"));
javamailsenderimpl.setusername(environment.getproperty("mail.username"));
javamailsenderimpl.setpassword(environment.getproperty("mail.password"));
javamailsenderimpl.setdefaultencoding(environment.getproperty("mail.encoding"));
return javamailsenderimpl;
}
}
邮件配置：mail.properties
#qq邮箱发送邮件服务器 mail.host=smtp.qq.com #qq邮箱账户名 mail.username=xxxxxx@qq.com #qq邮箱授权码，开启imap/smtp服务时会生成 mail.password=lrorsapyffcwbegg #邮件发送编码 mail.encoding=utf-8
测试
@runwith(springrunner.class)
@contextconfiguration(classes=springconfig.class)
public class mailtest {
@autowired
private javamailsenderimpl javamailsenderimpl;
@test
public void testsimplemail() throws messagingexception{
mimemessage message = javamailsenderimpl.createmimemessage();
//发送带附件和内联元素的邮件需要将第二个参数设置为true
mimemessagehelper helper = new mimemessagehelper(message, true);
//发送方邮箱，和配置文件中的mail.username要一致
helper.setfrom("xxxxxx@qq.com");
//接收方
helper.setto("xxxxxx@qq.com");
//主题
helper.setsubject("邮件测试");
//邮件内容
helper.settext("<html><body><img src='cid:myphoto'></body></html>", true);
//邮件内容内嵌的图片,addinline中的contentid要和邮件内容中的cid相对应
filesystemresource res = new filesystemresource(new file("e:/yc/1.jpg"));
helper.addinline("myphoto", res);
//邮件附件
filesystemresource file = new filesystemresource(new file("e:/yc/myphoto.zip"));
helper.addattachment("myphoto.zip", file);
javamailsenderimpl.send(message);
}
}
基于thymeleaf模版的邮件
导入thymeleaf-spring依赖
<dependency>
<groupid>org.thymeleaf</groupid>
<artifactid>thymeleaf-spring4</artifactid>
<version>3.0.11.release</version>
</dependency>
spring配置类中添加thymeleaf模板配置
@bean
public templateengine emailtemplateengine() {
springtemplateengine templateengine = new springtemplateengine();
classloadertemplateresolver templateresolver = new classloadertemplateresolver();
templateresolver.setresolvablepatterns(collections.singleton("*.html"));
templateresolver.setprefix("/templates/");
templateresolver.setsuffix(".html");
templateresolver.settemplatemode(templatemode.html);
templateresolver.setcharacterencoding("utf-8");
templateresolver.setcacheable(false);
templateengine.addtemplateresolver(templateresolver);
return templateengine;
}
模版文件：/src/main/resources/templates/msg.html
<!doctype html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<style type="text/css">span{color:orange}</style>
</head>
<body>
<p>
您好， <span th:text="${name}">xxx</span>，感谢您使用xxx服务，您正在进行邮箱验证，本次请求的验证码为：
</p>
<p><span th:text="${validcode}">1111</span>(为了保障您帐号的安全性，请在1小时内完成验证。)</p>

</html>
测试
@autowired
private templateengine emailtemplateengine;
@test
public void testtemplatemail() throws messagingexception{
mimemessage message = javamailsenderimpl.createmimemessage();
mimemessagehelper helper = new mimemessagehelper(message, true);
helper.setfrom("xxxxxx@qq.com");
helper.setto("xxxxxx@qq.com");
helper.setsubject("邮件测试");
//thymeleaf模版解析成string
context ctx = new context();
ctx.setvariable("name", "小姐姐");
ctx.setvariable("validcode", "88888888");
string htmlcontent = emailtemplateengine.process("msg.html", ctx);
helper.settext(htmlcontent, true);
javamailsenderimpl.send(message);
}
