java spring 开启SMTP服务发送QQ邮件

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="[email protected]"/>
        <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="[email protected]"/>
        <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>

}

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
