蓝莓商城

今天使用Spring的mail API发送邮件。
下面说一下流程。

Maven依赖

<dependency>  <groupId>javax.mail</groupId>  <artifactId>mail</artifactId>  <version>1.4.7</version>  
</dependency>  
<!--Spring mail 类库-->
<dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>5.0.4.RELEASE</version>
</dependency>

创建bean

启用邮箱smtp功能

可以看到smtp的服务器地址是：smtp.sina.com。即为下面的host值。
填入该邮箱的username和password，邮件将会从该邮箱发出。

<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"><property name="host" value="smtp.sina.com"></property><property name="username" value="xxxx@sina.com"></property><property name="password" value="xxxxx"></property><property name="javaMailProperties"><props><prop key="mail.smtp.auth">true</prop><prop key="mail.smtp.timeout">20000</prop></props></property></bean>

创建自定义发送的bean,

<bean id="userMailSender" class="org.lanmei.cms.email.UserMailSender"><property name="mailSender" ref="mailSender" /> 
</bean>

完整的配置文件：applicationContext-email.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"xmlns:context="http://www.springframework.org/schema/context"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-4.3.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.3.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"><bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"><property name="host" value="smtp.sina.com"></property><property name="username" value="lanmeishop1@sina.com"></property><property name="password" value="lanmei"></property><property name="javaMailProperties"><props><prop key="mail.smtp.auth">true</prop><prop key="mail.smtp.timeout">20000</prop></props></property></bean><bean id="userMailSender" class="org.lanmei.cms.email.UserMailSender"><property name="mailSender" ref="mailSender" /> </bean>
</beans>

编写UserMailSender类

mailSender已经在bean定义中进行依赖注入。

package org.lanmei.cms.email;import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;public class UserMailSender {private JavaMailSenderImpl   mailSender;public void send(SimpleMailMessage mail) {mailSender.send(mail);}public JavaMailSenderImpl getMailSender() {return mailSender;}public void setMailSender(JavaMailSenderImpl mailSender) {this.mailSender = mailSender;}   
}

编写测试类

package org.lanmei.cms;import org.junit.Test;
import org.lanmei.cms.email.UserMailSender;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.mail.SimpleMailMessage;public class UserMailSenderTest {@Testpublic void emailTest() {ApplicationContext ac = new ClassPathXmlApplicationContext("spring/applicationContext-email.xml");UserMailSender sender = (UserMailSender) ac.getBean("userMailSender");SimpleMailMessage mail = new SimpleMailMessage();mail.setTo("xxxxx@qq.com");//收件人邮箱地址mail.setFrom("xxxxx@sina.com");//发件人，需与mailSender  bean中的username一致mail.setSubject("spring自带javamail发送的邮件");//主题mail.setText("hello this mail is from spring javaMail ");//正文sender.send(mail);}}
