使用spring框架中的组件发送邮件功能说明

spring框架是由于软件开发的复杂性而创建的。spring使用的是基本的javabean来完成以前只可能由ejb完成的事情。然而，spring的用途不仅仅限于服务器端的开发。从简单性、可测试性和松耦合性角度而言，绝大部分java应用都可以从spring中受益。

首先进入自己的qq邮箱，在设置中修改账户信息

然后来至底部

点击开启，再用手机发送对应信息到指定号码，然后点击我已发送

获取授权码

注意提示：

到这里，相信你已经开通了smtp服务，这样就可以在java code发送邮件了

接下来的是spring 中使用邮件服务

首先是配置信息使用的是587端口，刚开始用465端口我纠结了好久(使用465端口的错误详情)，用不了，你可以尝试，默认的25端口应该也是不适合的

<!-- 邮件服务 -->
  <bean id="mailsender" class="org.springframework.mail.javamail.javamailsenderimpl">
    <property name="host" value="smtp.qq.com"/>
    <property name="port" value="587"/>//或许你可以用465端口，默认的25不适合
    <property name="protocol" value="smtp"/>
    <property name="username" value="[e-mail]"/>
    <property name="password" value="xxxxxxxxxxxx"/>//这里的是你通过短信后，获取的授权码
    <property name="defaultencoding" value="utf-8"/>
    <property name="javamailproperties"> 
      <props> 
        <prop key="mail.smtp.auth">true</prop> 
        <prop key="mail.smtp.timeout">25000</prop> 
      </props> 
    </property> 
  </bean>
  <!-- this is a template message that we can pre-load with default state -->
  <bean id="templatemessage" class="org.springframework.mail.simplemailmessage">
    <property name="from" value="[e-mail]"/>
    <property name="subject" value="尝试发邮件"/>
  </bean>
  <bean id="ordermanager" class="cn.cherish.common.simpleordermanager">
    <property name="mailsender" ref="mailsender"/>
    <property name="templatemessage" ref="templatemessage"/>
  </bean>

用maven引入的jar包

 <!-- 邮件 -->
  <dependency>
    <groupid>org.springframework</groupid>
    <artifactid>spring-context-support</artifactid>
    <version>${spring.version}</version>
  </dependency>
  <dependency>
    <groupid>javax.mail</groupid>
    <artifactid>mail</artifactid>
    <version>1.4.7</version>
  </dependency>

下面只是一个工具类作简单例子，请勿见怪

温馨提示：

<img src='cid:javaxmail.png'>

这是内嵌图片的方式 javaxmail.png 要和 messagehelper.addinline(file.getfilename(), file); 这里的 file.getfilename() 相一致就可以

现在只差一步了，那就是ctrl + f11，有不当之处敬请提出，共同进步
