Java Mail处理

            首先我用一种比较简单的方法，做了个小小的demo，但是这种方法用的的是Spring 框架来完成的，因为使用这种方法是一种比较实用的方法，由于很多的代码被Spring 封装在最底层。。具体的源代码如下：
Java 代码：

import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    import org.springframework.mail.SimpleMailMessage;
    import org.springframework.mail.javamail.JavaMailSender;

    public class Main {

        /**
        * @param args
       */
        public static void main(String[] args) {
         // TODO Auto-generated method stub
           ApplicationContext context = new ClassPathXmlApplicationContext("config.xml");
          JavaMailSender mailSender= (JavaMailSender) context.getBean("mailSender");
            SimpleMailMessage mail = new SimpleMailMessage();
          mail.setFrom("[email protected]");
            mail.setTo("[email protected]");
          mail.setSubject(" 测试Mail 程序");
          mail.setText("这里是发送的内容");
           mailSender.send(mail);
        }

    }

配置文件中的主要代码如下：
Spring-Mail.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

     <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="smtp.126.com" />
        <property name="port" value="25" />
        <property name="username" value="[email protected]" />
        <property name="password" value="你的密码" />
        <property name="javaMailProperties">
            <props>
                <prop key="mail.smtp.auth">true</prop>
            </props>
        </property>
    </bean>

</beans>

在此用纯Java代码做了个小demo来发送电子邮件：

package com.cmcc.mail;
/**
* 发送邮件需要使用的基本信息
*/
import java.util.Properties;
public class MailSenderInfo {
    // 发送邮件的服务器的IP和端口
    private String mailServerHost;
    private String mailServerPort = "25";
    // 邮件发送者的地址
    private String fromAddress;
    // 邮件接收者的地址
    private String toAddress;
    // 登陆邮件发送服务器的用户名和密码
    private String userName;
    private String password;
    // 是否需要身份验证
    private boolean validate = false;
    // 邮件主题
    private String subject;
    // 邮件的文本内容
    private String content;
    // 邮件附件的文件名
    private String[] attachFileNames;
    /**
      * 获得邮件会话属性
      */
    public Properties getProperties(){
      Properties p = new Properties();
      p.put("mail.smtp.host", this.mailServerHost);
      p.put("mail.smtp.port", this.mailServerPort);
      p.put("mail.smtp.auth", validate ? "true" : "false");
      return p;
    }
    public String getMailServerHost() {
      return mailServerHost;
    }
    public void setMailServerHost(String mailServerHost) {
      this.mailServerHost = mailServerHost;
    }
    public String getMailServerPort() {
      return mailServerPort;
    }
    public void setMailServerPort(String mailServerPort) {
      this.mailServerPort = mailServerPort;
    }
    public boolean isValidate() {
      return validate;
    }
    public void setValidate(boolean validate) {
      this.validate = validate;
    }
    public String[] getAttachFileNames() {
      return attachFileNames;
    }
    public void setAttachFileNames(String[] fileNames) {
      this.attachFileNames = fileNames;
    }
    public String getFromAddress() {
      return fromAddress;
    }
    public void setFromAddress(String fromAddress) {
      this.fromAddress = fromAddress;
    }
    public String getPassword() {
      return password;
    }
    public void setPassword(String password) {
      this.password = password;
    }
    public String getToAddress() {
      return toAddress;
    }
    public void setToAddress(String toAddress) {
      this.toAddress = toAddress;
    }
    public String getUserName() {
      return userName;
    }
    public void setUserName(String userName) {
      this.userName = userName;
    }
    public String getSubject() {
      return subject;
    }
    public void setSubject(String subject) {
      this.subject = subject;
    }
    public String getContent() {
      return content;
    }
    public void setContent(String textContent) {
      this.content = textContent;
    }
}
