1.导包
<!--发送邮件 https://mvnrepository.com/artifact/com.sun.mail/javax.mail --> <dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.6.2</version> </dependency>
2.配置文件
mail.propertiex
#服务器主机名 smtp.xx.com
mail.host=smtp.qq.com
mail.username=XXXXXX@qq.com
#密码/客户端授权码
mail.password=XXXXXXXXXX
#编码字符
mail.defaultEncoding=utf-8
#是否进行用户名密码校验
mail.auth=true
#设置超时时间
mail.timeout=20000
3.配置到容器中
<!-- 读取邮件配置文件, 其中ignore-unresolvable="true"属性是配置文件中存在 多个property-placeholder时出现解析不了的占位符进行忽略掉, --> <context:property-placeholder location="classpath:mail.properties" ignore-unresolvable="true"/>
<!--配置邮件接口--> <bean id="javaMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="${mail.host}"/> <property name="username" value="${mail.username}"/> <property name="password" value="${mail.password}"/> <property name="defaultEncoding" value="${mail.defaultEncoding}"/> <property name="javaMailProperties"> <props> <prop key="mail.smtp.auth">${mail.auth}</prop> <prop key="mail.smtp.timeout">${mail.timeout}</prop> </props> </property> </bean>
