Spring整合javamail成功之后，把大量的代码配置到spring的配置文件里了 ，从而降低了Javamail对邮箱、端口、协议、主题、内容…… 的耦合。在客户端上只需要调用一行代码就可以发送邮件了。
首先不需要往项目的lib里导入jar，但是需要在tomcat的lib里导入3个jar文 件activation.jar ，jspsmartupload.jar，mail.jar 导入这3个jar文件，这样 tomcat就不会报错了。
SendManagerService .java
package com.cgt.itspiderman.service.email;
public interface SendManagerService {
public void sendMail(String email);
}
定义一个发送邮件的接口.
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;
}
}
