Spring整合javamail成功之後,把大量的代碼配置到spring的配置文件裡了 ,從而降低了Javamail對郵箱、端口、協議、主題、內容…… 的耦合。在客戶端上只需要調用一行代碼就可以發送郵件了。
首先不需要往項目的lib裡導入jar,但是需要在tomcat的lib裡導入3個jar文 件activation.jar ,jspsmartupload.jar,mail.jar 導入這3個jar文件,這樣 tomcat就不會報錯了。
SendManagerService .java
package com.cgt.itspiderman.service.email;
public interface SendManagerService {
public void sendMail(String email);
}
定義一個發送郵件的接口.
SendManagerServiceImp.java
package com.cgt.itspiderman.service.email;
import javax.mail.Message;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessagePreparator;
public class SendManagerServiceImp implements SendManagerService {
private JavaMailSender mailSender;
private SimpleMailMessage message;
public void sendMail(final String email) {
// TODO Auto-generated method stub
MimeMessagePreparator preparator = new MimeMessagePreparator()
{
public void prepare(MimeMessage mimeMessage) throws Exception {
mimeMessage.setRecipient (Message.RecipientType.TO, new InternetAddress(email));
mimeMessage.setFrom(new InternetAddress(message.getFrom()));
mimeMessage.setSubject (message.getSubject(),"gbk");
mimeMessage.setText(message.getText (),"gbk");
}
};
mailSender.send(preparator);
}
public JavaMailSender getMailSender() {
return mailSender;
}
public void setMailSender(JavaMailSender mailSender) {
this.mailSender = mailSender;
}
public SimpleMailMessage getMessage() {
return message;
}
public void setMessage(SimpleMailMessage message) {
this.message = message;
}
}
發送郵件的實現類.
然後在WEB-INF下面創建一個文件messages.properties,以後修改配置信息 直接在這裡修改就可以了。
host=smtp.gmail.com
[email protected]
password=xxxxxx
port=465
mail.smtp.auth=true
mail.smtp.timeout=25000
mail.smtp.starttls.enable=true
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.smtp.socketFactory.fallback=false
[email protected]
subject=\u6807\u9898
text=\u5185\u5BB9\u554A
applicationContext.xml

............................
public static void main(String[] args) {
ApplicationContext context= null;
context = new ClassPathXmlApplicationContext ("applicationContext.xml");
SendManagerService sms= (SendManagerService) context.getBean("sendmail");
sms.sendMail("[email protected]");
}
如果是在struts2裡使用的話需要在Action裡加上private SendManagerService sendemail;(加上get和set),然後在spring裡配置這個 Action的時候加上<property name="sendemail" ref="sendmail"></property>
然後在Action裡調用下面這一行代碼就可以發送了。
sendemail.sendMail("[email protected]");
寫到這裡大家會問,如果需要動態的修改這個郵件的內容呢?方法很簡單
WebApplicationContext context=WebApplicationContextUtils.getRequiredWebApplicationContext (ServletActionContext.getServletContext());
((SimpleMailMessage) context.getBean ("mailMessage")).setText("我現在修改了郵件的內容 呵呵呵");
