spring发送邮件

Spring邮件抽象层的主要包为org.springframework.mail。它包括了发送电子邮件的主要接口MailSender，和值对象SimpleMailMessage，它封装了简单邮件的属性如from, to,cc, subject,text。 包里还包含一棵以MailException为根的checked Exception继承树，它们提供了对底层邮件系统异常的高级别抽象。 要获得关于邮件异常层次的更丰富的信息，请参考Javadocs。

为了使用JavaMail中的一些特色, 比如MIME类型的信件, Spring提供了MailSender的一个子接口, 即org.springframework.mail.javamail.JavaMailSender。Spring还提供了一个回调接口org.springframework.mail.javamail.MimeMessagePreparator,  用于准备JavaMail的MIME信件。

这里简单的介绍了如何使用spring发送各种形式的邮件以及配置。

一，Spring配置发送邮件

1，配置邮件发送信息

#sys.mail.protocol=smtp
sys.mail.transport.protocol=smtp
sys.mail.host=smtp.exmail.qq.com
sys.mail.sysEmailAddress=***@***.com
sys.mail.password=***
sys.mail.debug=true
sys.mail.smtp.auth=true
sys.mail.smtp.timeout=25000
sys.mail.smtp.port=465
sys.mail.smtp.ssl.enable=true
sys.mail.toSet=****,***,***

　　2，spring配置信息

    <!--	邮件发票配置		-->
    <util:properties id="mailProp" location="classpath:config/mail.properties"/>

    <bean class="org.springframework.beans.factory.config.PropertiesFactoryBean" id="configProperties">
        <property name="locations">
            <list>
                <value>classpath:config/mail.properties</value>
            </list>
        </property>
    </bean>

    <!-- 邮件发送   -->
    <bean class="org.springframework.mail.javamail.JavaMailSenderImpl" id="mailSender">
        <property name="host" value="#{mailProp['sys.mail.host']}"></property>
        <property name="username" value="#{mailProp['sys.mail.sysEmailAddress']}"></property>
        <property name="password" value="#{mailProp['sys.mail.password']}"></property>
        <property name="protocol" value="#{mailProp['sys.mail.transport.protocol']}"></property>
        <property name="defaultEncoding" value="UTF-8"></property>
        <property name="javaMailProperties">
            <props>
                <prop key="mail.debug">#{mailProp['sys.mail.debug']}</prop>
                <prop key="mail.smtp.auth">#{mailProp['sys.mail.smtp.auth']}</prop>
                <prop key="mail.smtp.timeout">#{mailProp['sys.mail.smtp.timeout']}</prop>
                <prop key="mail.smtp.port">#{mailProp['sys.mail.smtp.port']}</prop>
                <prop key="mail.smtp.ssl.enable">#{mailProp['sys.mail.smtp.ssl.enable']}</prop>
                <prop key="mail.transport.protocol">#{mailProp['sys.mail.transport.protocol']}</prop>
            </props>
        </property>
    </bean>
</beans>

　　3，注入发送配置信息

4，发送邮件

/**
     * 发送邮件
     */
    public void sendMail(JavaMailSender mailSender, String from, Set<String> set, String subject, String content, Boolean isHtml, Boolean isAttachment, Map<String, File> attachments) throws Exception {

        MimeMessage message = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(message, isAttachment);

        //添加发送者
        helper.setFrom(from);

//                Set<String> toSet = simpleEmail.getToSet();
        //添加接收者
        helper.setTo(set.toArray(new String[set.size()]));

        //添加主题
        helper.setSubject(subject);
        //添加正文
        helper.setText(content, isHtml);

        //添加附件
        if (isAttachment && attachments != null) {
            for (Map.Entry<String, File> attach : attachments.entrySet()) {
                helper.addAttachment(attach.getKey(), attach.getValue());
            }
        }

        JavaMailSenderImpl javaMailSender = (JavaMailSenderImpl) mailSender;
　　　　///避开认证问题
        MailSSLSocketFactory sf = new MailSSLSocketFactory();
        sf.setTrustAllHosts(true);
        javaMailSender.getJavaMailProperties().put("mail.smtp.ssl.socketFactory", sf);
        javaMailSender.send(message); // 发送
    }

　　二，javaMail发送工具类

import com.sun.mail.util.MailSSLSocketFactory;

import javax.mail.Address;
import javax.mail.Message;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import java.util.Date;
import java.util.Properties;

public class EmailUtil {
    public static void sendMail(String fromMail, String user, String password, String toMail, String mailTitle, String mailContent) throws Exception {
        Properties props = new Properties();
        // 开启debug调试
        props.setProperty("mail.debug", "true");
        // 发送服务器需要身份验证
        props.setProperty("mail.smtp.auth", "true");

        MailSSLSocketFactory sf = new MailSSLSocketFactory();
        sf.setTrustAllHosts(true);
        props.put("mail.smtp.ssl.enable", "true");
        props.put("mail.smtp.ssl.socketFactory", sf);
        Session session = Session.getInstance(props);
        Message msg = new MimeMessage(session);
        msg.setSubject(mailTitle);
        msg.setText(mailContent);
        msg.setFrom(new InternetAddress(fromMail));
        Transport transport = session.getTransport();
        transport.connect("smtp.exmail.qq.com", fromMail, password);

        transport.sendMessage(msg, new Address[]{new InternetAddress(toMail)});
        transport.close();
    }

    public static void main(String[] args) throws Exception {
        EmailUtil.sendMail("***@***.com","ces","***","***@qq.com","测试","测试");
    }
