自己的代码魔改太多起不到简单易懂的效果，我还是直接上原来的人的代码吧。

代码结构如下：

1、pom.xml中加入以下依赖：

<dependency>
         <groupId>org.springframework</groupId>
         <artifactId>spring-context-support</artifactId>
         <version>4.2.6.RELEASE</version>
    </dependency>
<dependency>
         <groupId>javax.mail</groupId>
         <artifactId>mail</artifactId>
         <version>1.4.7</version>
</dependency>

2、applicationContext.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
   <bean id="configurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
      <property name="locations">
         <list>
            <value>/mail.properties</value>
         </list>
      </property>
   </bean>
   <bean class="org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor" />
   <bean id="MailSenderDemo" class="com.mail.MailSenderDemo">
   </bean>
</beans>

3、mail.properties如下：主要是邮箱服务器、个人邮箱用户名和开启smtp服务后获得的授权码（非密码），

mail.host=smtp.163.com
mail.username=*****@163.com
mail.password=******

4、spring-mail.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
   <property name="host" value="${mail.host}"></property>
   <property name="javaMailProperties">
       <props>
          <prop key="mail.smtp.auth">true</prop>
          <prop key="mail.smtp.timeout">25000</prop>
       </props>
   </property>
   <property name="username" value="${mail.username}"></property>
   <property name="password" value="${mail.password}"></property>
</bean>
</beans>

5.MailSenderDemo.java如下：

public class MailSenderDemo {
    @Autowired
    private JavaMailSender mailSender;
    public void send(SimpleMailMessage mail){
     mailSender.send(mail);
    }
}

6、测试类SendTest.java如下：

public class SendTest {

    public static void main(String[] args) {
        ApplicationContext ac = new ClassPathXmlApplicationContext("spring-mail.xml",
                "applicationContext.xml");
        MailSenderDemo sender = (MailSenderDemo)ac.getBean("MailSenderDemo");
        SimpleMailMessage mail = new SimpleMailMessage();
        mail.setTo("gu.erlei@ustcinfo.com");//收件人邮箱地址
        mail.setFrom("gu.erlei@ustcinfo.com");//收件人
        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);
    }
}

结果
