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="785427346@qq.com"/><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="785427346@qq.com"/><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>

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() 相一致就可以显示

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
