Spring在bean配置文件中定义电子邮件模板 - Spring教程

在上一篇Spring电子邮件教程，硬编码的所有电子邮件属性和消息的方法体中的内容，这是不实际的，应予以避免。应该考虑在Spring bean 配置文件中定义电子邮件模板。

1.Spring的邮件发件人

Java类使用 Spring的MailSender接口发送电子邮件，并使用 String.Format 传递变量bean配置文件替换电子邮件中的 '%s'。

File : MailMail.java

package com.yiibai.common;

import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

public class MailMail
{
    private MailSender mailSender;
    private SimpleMailMessage simpleMailMessage;

    public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
        this.simpleMailMessage = simpleMailMessage;
    }

    public void setMailSender(MailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void sendMail(String dear, String content) {

       SimpleMailMessage message = new SimpleMailMessage(simpleMailMessage);

       message.setText(String.format(
            simpleMailMessage.getText(), dear, content));

       mailSender.send(message);

    }    
}

2. Bean的配置文件

定义电子邮件模板“customeMailMessage' 和邮件发件人信息的bean配置文件。

File : Spring-Mail.xml

<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-2.5.xsd">

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host" value="smtp.gmail.com" />
    <property name="port" value="587" />
    <property name="username" value="username" />
    <property name="password" value="password" />

    <property name="javaMailProperties">
         <props>
               <prop key="mail.smtp.auth">true</prop>
               <prop key="mail.smtp.starttls.enable">true</prop>
                </props>
    </property>
</bean>

<bean id="mailMail" class="com.yiibai.common.MailMail">
    <property name="mailSender" ref="mailSender" />
    <property name="simpleMailMessage" ref="customeMailMessage" />
</bean>

<bean id="customeMailMessage"
    class="org.springframework.mail.SimpleMailMessage">

    <property name="from" value="[email protected]" />
    <property name="to" value="[email protected]" />
    <property name="subject" value="Testing Subject" />
    <property name="text">
       <value>
        <![CDATA[
            Dear %s,
            Mail Content : %s
        ]]>
       </value>
        </property>
</bean>

</beans>

4. 运行它

package com.yiibai.common;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App 
{
    public static void main( String[] args )
    {
        ApplicationContext context = 
           new ClassPathXmlApplicationContext("applicationContext.xml");

        MailMail mm = (MailMail) context.getBean("mailMail");
        mm.sendMail("Yiibai", "This is text content");

    }
}

输出

Dear Yiibai,
 Mail Content : This is text content
