SpringMVC 邮件发送配置及代码,springmvc邮件发送,首先是spring中的配


首先是spring中的配置:(里面使用了FreeMarker模板引擎)

<!--邮件发送实现类-->    <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">        <property name="host" value="smtp.qq.com"/>        <property name="port" value="25"/>        <property name="username" value="你的邮箱"/>        <property name="password" value="你的邮箱密码"/>        <property name="javaMailProperties">            <props >                <prop key="mail.smtp.auth">true</prop>            </props>        </property>    </bean>    <bean id="simpleMailMessage" class="org.springframework.mail.SimpleMailMessage">        <property name="from" value="发件人" />        <property name="subject" value="邮件主题" />        <!--        <property name="text" value="邮件内容" />        -->    </bean> <!--线程池异步发送邮件-->    <bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">        <property name="corePoolSize" value="5" />        <property name="maxPoolSize" value="10" />        <property name="queueCapacity" value="25" />    </bean>    <!--FreeMarker模板-->    <bean id="freeMarkerConfigurer" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">        <property name="templateLoaderPath" value="classpath:template" />        <!--<property name="templateLoaderPath" value="/template" />-->        <property name="freemarkerSettings">            <props>                <prop key="locale">zh_CN</prop>                <prop key="default_encoding">UTF-8</prop>            </props>        </property>    </bean>

发送邮件的工具类:(采用注解形式注入管理邮件发送的类)

public class MailSender {    @Inject    private JavaMailSender javaMailSender;    @Inject    private SimpleMailMessage simpleMailMessage;    @Inject    private FreeMarkerConfigurer freeMarkerConfigurer;    @Inject    private TaskExecutor taskExecutor;    /**     * 构建邮件内容,发送邮件。     * @param user  用户     * @param url   链接     */    public void send(User user, String url,String email) {        String nickname = user.getNickname();        String to = email;        String text = "";        Map<String, String> map = new HashMap<String, String>(1);        map.put("url", url);        try {//            从FreeMarker模板生成邮件内容            Template template = freeMarkerConfigurer.getConfiguration().getTemplate("register_mail.ftl");//            模板中用${XXX}站位,map中key为XXX的value会替换占位符内容。            text = FreeMarkerTemplateUtils.processTemplateIntoString(template, map);        } catch (IOException e) {            e.printStackTrace();        } catch (TemplateException e) {            e.printStackTrace();        }        this.taskExecutor.execute(new SendMailThread(to,null,text));    }    //    内部线程类,利用线程池异步发邮件。    private class SendMailThread implements Runnable {        private String to;        private String subject;        private String content;        private SendMailThread(String to, String subject, String content) {            super();            this.to = to;            this.subject = subject;            this.content = content;        }        @Override        public void run() {            sendMail(to, subject, content);        }    }    /**     * 发送邮件     * @param to        收件人邮箱     * @param subject   邮件主题     * @param content   邮件内容     */    public void sendMail(String to, String subject, String content) {        try {            MimeMessage message = javaMailSender.createMimeMessage();            MimeMessageHelper messageHelper = new MimeMessageHelper(message, true, "UTF-8");            messageHelper.setFrom(simpleMailMessage.getFrom());            if (subject != null) {                messageHelper.setSubject(subject);            } else {                messageHelper.setSubject(simpleMailMessage.getSubject());            }            messageHelper.setTo(to);            messageHelper.setText(content, true);           javaMailSender.send(message);        } catch (MessagingException e) {            e.printStackTrace();        }    }}

服务层调用:

1、要注入发送邮件工具类

    @Inject    private MailSender mailSender;

2、调用代码

        User user = (User)request.getSession().getAttribute("user");        String url = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+                request.getContextPath();        mailSender.send(user,url,email);
