前言:以前都是直接用java自带的邮件工具发送邮件,现在spring帮我们做了封装,提供了更好用更简单的发送邮件工具javamailsender,关于邮件服务器的设置就不在这里说了,直接去qq邮箱设置下就好,下面看下主要的步骤:
步骤一、添加发送邮件相关maven依赖
<!-- spring 邮件发送 --> <dependency> <groupid>org.springframework</groupid> <artifactid>spring-context-support</artifactid> <version>4.3.2.release</version> </dependency> <dependency> <groupid>javax.mail</groupid> <artifactid>mail</artifactid> <version>1.4.7</version> </dependency>
步骤二、添加相关spring配置,创建一个spring-mail.xml(如果是spring-boot请无视),内容如下:
<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd "> <!-- spring javamailsender --> <bean class="org.springframework.mail.javamail.javamailsenderimpl"> <property name="host" value="smtp.qq.com"></property> <!-- 或许你可以用465端口,默认的25不适合 --> <property name="port" value="587"/> <property name="protocol" value="smtp"/> <property name="username" value="******@qq.com"></property> <!-- 这里的是你在qq邮箱发送开通smtp短信后,获取的授权码 --> <property name="password" value="******"></property> <property name="defaultencoding" value="utf-8"/> <property name="javamailproperties"> <props> <prop key="mail.smtp.auth">true</prop> <prop key="mail.smtp.timeout">25000</prop> </props> </property> </bean> </beans>
步骤三、创建具体的邮件发送工具类
/** * 基于spring的javamailsender的邮件发送工具类 * @author simon * */ @component public class emailsender { @autowired private javamailsender javamailsender; private static emailsender emailsender; @postconstruct public void init() { emailsender = this; emailsender.javamailsender= this.javamailsender; } /** * 发送简单的文本邮件 * @param sendto 收件人组 * @param subject 主题 * @param content 文本内容 */ public static void sendsimplemessage(string sendfrom, string[] sendto, string subject, string textcontent) { simplemailmessage mail = new simplemailmessage(); mail.setfrom(sendfrom); mail.setto(sendto); mail.setsubject(subject); mail.settext(textcontent); //发送 emailsender.javamailsender.send(mail); } /** * 发送html内容格式的邮件 * @param sendfrom * @param sendto 收件人组 * @param subject 主题 * @param htmlcontent html内容 * @throws exception */ public static void sendhtmlmessage(string sendfrom, string[] sendto, string subject, string htmlcontent) throws exception { mimemessage mimemessage = emailsender.javamailsender.createmimemessage(); mimemessagehelper mimemessagehelper = new mimemessagehelper(mimemessage); mimemessagehelper.setfrom(sendfrom); mimemessagehelper.setto(sendto); mimemessagehelper.setsubject(subject); // true 表示启动html格式的邮件 mimemessagehelper.settext(htmlcontent, true); // 发送邮件 emailsender.javamailsender.send(mimemessage); } }
步骤四、创建单元测试测试发送邮件
/** * 邮件发送测试类 * * @author simon * */ @runwith(springjunit4classrunner.class) @contextconfiguration("classpath:applicationcontext.xml") public class emailsendertest { @test public void testsend() throws exception { string sendfrom = "1317492210@qq.com"; string[] sendto = {"zhaosheng@hitencent.com"}; string subject = "spring自带javamailsender发送的html邮件"; stringbuilder htmlcontent = new stringbuilder() .append("<html>") .append("<head>") .append("<title>") .append("spring自带javamailsender发送的html邮件") .append("</title>") .append("</head>") .append("<body>") .append("您好!陌生人<p/>") .append("</body>") .append("</html>"); emailsender.sendhtmlmessage(sendfrom, sendto, subject, htmlcontent.tostring()); system.out.println("邮件发送成功."); }
ok,到这里全部的步骤就结束了,是不是比java mail简单方便很多哉,赶紧自己动手试试吧!
