Java通过Spring配置发送QQ邮件

Java通过Spring配置发送QQ邮件:

1, 通过Maven依赖相关Jar包

<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

2, Spring配置
2.1, 添加mail.properties文件, 并让加载该文件到Spring容器

mail.host=smtp.qq.com
mail.port=587
mail.username=xxxx@qq.com
mail.password=xxxx

2.2, 添加Spring.xml配置(这里也可以使用Spring java Connfig 配置)

<!-- 申明JavaMailSenderImpl对象 -->
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="defaultEncoding" value="UTF-8" />
<property name="host" value="${mail.host}" />
<property name="port" value="${mail.port}"/>
<property name="username" value="${mail.username}" />
<property name="password" value="${mail.password}" />
<property name="javaMailProperties">
<props>
<prop key="mail.smtp.auth">true</prop>
<prop key="mail.debug">false</prop>
<prop key="mail.smtp.timeout">5000</prop>
</props>
</property>
</bean>

3, Java使用

@Autowired
private MailSender mailSender;

SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setFrom("xxxxx@qq.com");
mailMessage.setSubject("你好");
mailMessage.setText("这个是一个通过Spring框架来发送邮件的小程序");
mailMessage.setTo("xxxx@qq.com");
mailSender.send(mailMessage);
