这是很久之前的代码了，最近需要使用了，了就记录一下。
maven：
<dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.5.5</version> </dependency>
spring配置：
<!-- 邮件 -->
<bean id="baojingMailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<!-- 服务器 -->
<property name="host" value="#{configproperties[‘baojing.mail.host‘]}" />
<property name="protocol" value="#{configproperties[‘baojing.mail.protocol‘]}"></property>
<!-- 端口号 -->
<property name="port" value="#{configproperties[‘baojing.mail.port‘]}" />
<!-- 用户名 -->
<!-- <property name="username" value="#{configproperties[‘baojing.mail.username‘]}" /> -->
<!-- 密码 -->
<!-- <property name="password" value="#{configproperties[‘baojing.mail.password‘]}" /> -->
<!-- SMTP服务器验证 -->
<property name="javaMailProperties">
<props>
<!-- 验证身份 -->
<prop key="mail.smtp.auth">{configproperties[‘baojing.mail.smtp.auth‘]}</prop>
<prop key="mail.smtp.timeout">#{configproperties[‘baojing.mail.smtp.timeout‘]}</prop>
</props>
</property>
</bean>
配置：
baojing.mail.host = mail2-in.XXXX.com baojing.mail.port = 25 baojing.mail.protocol = smtp baojing.mail.username = "" baojing.mail.password = "" baojing.mail.smtp.auth = false baojing.mail.smtp.timeout = 25000
代码：
