Email郵件發送與激活

1.導包

<!--發送郵件 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

#服務器主機名 smtp.xx.com
mail.host=smtp.qq.com
mail.username=[e-mail]
#密碼/客戶端授權碼
mail.password=XXXXXXXXXX
#編碼字符
mail.defaultEncoding=utf-8
#是否進行用戶名密碼校驗
mail.auth=true
#設置超時時間
mail.timeout=20000

3.配置到容器中

<!--
           讀取郵件配置文件,
           其中ignore-unresolvable="true"屬性是配置文件中存在
           多個property-placeholder時出現解析不了的占位符進行忽略掉，
       -->
    <context:property-placeholder location="classpath:mail.properties" ignore-unresolvable="true"/>

 <!--配置郵件接口-->
    <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>
