Spring整合javamail 用gmail发送邮件

Spring整合javamail 用gmail发送邮件

副标题#e#

Spring整合javamail乐成之后,把大量的代码设置到spring的设置文件里了 ,从而低落了Javamail对邮箱、端口、协议、主题、内容…… 的耦合。在客户端上只需要挪用一行代码就可以发送邮件了。

首先不需要往项目标lib里导入jar,可是需要在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);
}

界说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;
    }

}

发送邮件的实现类.

然后在WEB-INF下面建设一个文件messages.properties,今后修改设置信息 直接在这里修改就可以了。

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

    <!-- gmail 发送邮箱的设置文件 -->

……………………….

#p#分页标题#e#

public static void main(String[] args) {

        ApplicationContext context= null;
        context = new ClassPathXmlApplicationContext ("applicationContext.xml");
        SendManagerService sms=    (SendManagerService) context.getBean("sendmail");
        sms.sendMail("[email protected]");
    }

假如是在struts2里利用的话需要在Action里加上private SendManagerService sendemail;(加上get和set),然后在spring里设置这个 Action的时候加上<property name="sendemail" ref="sendmail"></property>

然后在Action里挪用下面这一行代码就可以发送了。

sendemail.sendMail("[email protected]");

写到这里各人会问,假如需要动态的修改这个邮件的内容呢?要领很简朴

WebApplicationContext context=WebApplicationContextUtils.getRequiredWebApplicationContext (ServletActionContext.getServletContext());
((SimpleMailMessage) context.getBean ("mailMessage")).setText("我此刻修改了邮件的内容 呵呵呵");
