Spring用velocity發送email

用spring 發送郵件，需要sun的兩個jar包，activaton.jar和mail.jar

 

首先是要在spring的配置文件裏配置以下內容

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>WEB-INF/mail.properties</value> <value>WEB-INF/jdbc.properties</value> </list> </property> </bean> <!-- 郵件發送器 --> <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="${mail.host}" /> <property name="username" value="${mail.username}" /> <property name="password" value="${mail.password}" /> <property name="defaultEncoding" value="GBK"></property> <property name="javaMailProperties"> <props> <prop key="mail.smtp.auth">${mail.smtp.auth}</prop> <prop key="mail.smtp.timeout">${mail.smtp.timeout}</prop> </props> </property> </bean> <bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean"> <property name="resourceLoaderPath" value="WEB-INF/velocity"></property> </bean> <bean id="mailMessage" class="com.winking.spring.mvc.common.manager.mail.MailMessageTemplate"> <property name="javaMailSender" ref="mailSender"></property> <property name="from" value="[e-mail]"></property> <property name="encoding" value="GBK"></property> <property name="templateLocation" value="mailtemplate.vm"></property> <property name="velocityEngine" ref="velocityEngine"></property> <property name="title" value="默認title，我看好你"></property> </bean> <bean id="mailService" class="com.winking.spring.mvc.service.MailServiceImpl"> <property name="template" ref="mailMessage"></property> </bean>

velocity 引擎是WEB-INF/velocity下的maitemplate.vm。

 

mail.properties:

mail.from=[e-mail] mail.host=smtp.163.com mail.password=5202004 mail.smtp.auth=true mail.smtp.timeout=25000 mail.username=qxyqqxyq

 

這是一個service,提供給WEB層使用的。

public class MailServiceImpl implements MailService { private MailMessageTemplate template; public void sendMail() { Map<String, String> data = new HashMap<String, String>(); data.put("name", "***，貝克漢姆"); template.setModel(data); template.setToEmail("******[e-mail]"); template.setTitle("英文"); template.send(); } public MailMessageTemplate getTemplate() { return template; } public void setTemplate(MailMessageTemplate template) { this.template = template; } }

 

這是郵件發送器，有很大的優化空間。
