这次来看看Spring提高的一些有用过的JEE中使用到的功能,如发送Email, 执行定时任务...
先来看看发送Email吧, 在Spring中发送Email是很简单的,使用Spring提高的MailSender和MailMessage就可以了,配置代码如下:
<? xml version = "1.0" encoding = "UTF-8" ?>
<! DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "spring-beans.dtd" >
< beans >
< bean id = "mailSender" class = "org.springframework.mail.javamail.JavaMailSenderImpl" >
< property name = "host" >
< value > smtp.163.com </ value >
</ property >
< property name = "javaMailProperties" >
< props >
<!-- 如果要使用用户名和密码验证,这一步需要 -->
< prop key = "mail.smtp.auth" > true </ prop >
</ props >
</ property >
< property name = "username" >
< value > 你的Email地址 </ value >
</ property >
< property name = "password" >
< value > 你的Email密码 </ value >
</ property >
</ bean >
<!-- 简单的message -->
< bean id = "mailMessage" class = "org.springframework.mail.SimpleMailMessage" >
< property name = "to" >
< value > 收件人地址 </ value >
</ property >
< property name = "from" >
< value > 你的地址 </ value >
</ property >
< property name = "subject" > <!-- Email 标题 -->
< value > A Spring Mail sender </ value >
</ property >
</ bean >
<!-- 测试发送的类 -->
< bean id = "testMailSender" class = "test.mail.TestSenderMail" >
< property name = "mailMessage" >
< ref bean = "mailMessage" />
</ property >
< property name = "mailSender" >
< ref bean = "mailSender" />
</ property >
</ bean >
</ beans >
上面的配置好以后就可以直接发送了, 看看TestSenderMail.java的代码:
package test.mail;
import org.springframework.mail.MailException;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;
public class TestSenderMail {
private MailSender mailSender;
private SimpleMailMessage mailMessage;
public TestSenderMail() {
}
public SimpleMailMessage getMailMessage() {
return mailMessage;
}
public void setMailMessage(SimpleMailMessage mailMessage) {
this.mailMessage = mailMessage;
}
public MailSender getMailSender() {
return mailSender;
}
public void setMailSender(MailSender mailSender) {
this.mailSender = mailSender;
}
public void sendMail() {
SimpleMailMessage message = new SimpleMailMessage(mailMessage);
//设置email内容,
message.setText("测试Spring 发送Email.");
try {
mailSender.send(message);
} catch (MailException e) {
// TODO Auto-generated catch block
System.out.println("O . 发送Email失败了....");
e.printStackTrace();
}
}
}
很简单吧. 下面是测试类: TestApp.java
package test.mail;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestApp {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
ApplicationContext context = new ClassPathXmlApplicationContext(
"test/mail/mail.xml");
TestSenderMail sender = (TestSenderMail) context
.getBean("testMailSender");
sender.sendMail();
}
//抛出如下异常,是瑞星监控的问题,关闭就可以了
/**
* DEBUG SMTP: QUIT failed with 250 O . 发送Email失败了....
* org.springframework.mail.MailSendException: Could not send mails: 354
*
* com.sun.mail.smtp.SMTPSendFailedException: 354
*
* at
* com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
* at com.sun.mail.smtp.SMTPTransport.finishData(SMTPTransport.java:1215) at
* com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:586)
*/
}
呵呵, 现在就可以发送Email了.
