在springside中发送邮件

在springMVC框架中使用邮件发送功能（非定时、只能发送指定的文本内容），具体的使用方法如下：

在pom文件中加入：

<dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4.7</version>
        </dependency>
        <dependency>
            <groupId>org.apache.geronimo.specs</groupId>
            <artifactId>geronimo-activation_1.1_spec</artifactId>
            <version>1.1</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>freemarker</groupId>
            <artifactId>freemarker</artifactId>
            <version>2.3.9</version>
        </dependency>

在resources文件夹下，添加一个Email的xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd"
       default-lazy-init="true">

    <description>Email配置</description>

    <bean id="smtpAuthenticator" class="com.ziqikeji.sdhdjk.utilities.email.SmtpAuthenticator">
        <constructor-arg value="[email protected]" ></constructor-arg>
        <constructor-arg value="6168697000" ></constructor-arg>
    </bean>

    <bean id="mailSession" class="javax.mail.Session" factory-method="getInstance">
        <constructor-arg>
            <props>
                <prop key="mail.smtp.auth">true</prop>
                <prop key="mail.smtp.socketFactory.port">465</prop>
                <prop key="mail.smtp.socketFactory.class">javax.net.ssl.SSLSocketFactory</prop>
                <prop key="mail.smtp.socketFactory.fallback">false</prop>
            </props>
        </constructor-arg>
        <constructor-arg ref="smtpAuthenticator" />
    </bean>

    <!-- 文本邮件服务类 -->
    <bean id="simpleMailService" class="com.ziqikeji.sdhdjk.utilities.email.SimpleMailService">
        <property name="mailSender" ref="mailSender" />
        <property name="freemarkerConfiguration" ref="freemarkerConfiguration" />
    </bean>

    <!-- 邮件发送器 -->
    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="smtp.qq.com" />
        <property name="port" value="25"/>
        <property name="session" ref="mailSession"/>
        <property name="defaultEncoding" value="UTF-8"/>
    </bean>
</beans>

在web.xml中添加：

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:/email/applicationContext-email.xml,
                             ......
        </param-value>
    </context-param>    

至此，配置结束。

在src的项目文件夹中，添加一个纯文本邮件的服务类：

/**
     * 发送纯文本的用户修改通知邮件.
     */
    public void sendMail() {
        try {
            MimeMessage msg = mailSender.createMimeMessage();
            MimeMessageHelper helper = new MimeMessageHelper(msg, true, DEFAULT_ENCODING);
            helper.setTo(“被发送者的邮箱”);
            helper.setFrom("发送者的邮箱");
            helper.setSubject(“要发送的标题”);
            //要发送的内容，大家可以自己找方法，在这我就不具体说了
            mailSender.send(msg);
        } catch (MessagingException e) {
            logger.error("构造邮件失败", e);
        } catch (Exception e) {
            logger.error("发送邮件失败", e);
        }
    }

在controller或service里边利用下面的代码调用：

 邮件服务类名.sendMail();
