前言：當然，發 email 不一定要用 Spring，直接用 javax.mail 的API 就能實現。但是由于 Spring 提供了一個發送電子郵件的高級抽象層，
它向用戶屏蔽了底層郵件系統的一些細節，同時負責低層次的代表客戶端的資源處理。所以用 Spring 來發送 email 會省事很多和讓發郵件變的簡單許多。
Spring郵件抽象層的主要包為org.springframework.mail。它包括了發送電子郵件的主要接口MailSender和封裝了簡單郵件屬性的值對象SimpleMailMessage。

環境：

Spring 2.5.6

Javamail 1.4.4

Maven 3.0.4

Myeclipse 8.6.1

項目結構：

spring-smtp-mail.xml

<beans xmlns=http://www.springframework.org/schema/beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

目前我用過的EMAIL賬號都是網易的,下面列出網易的SMTP服務器名和端口號:

Email.java

package com.fancy.util;

import org.springframework.mail.MailSender;

import org.springframework.mail.SimpleMailMessage;

/**

public class Email {

private MailSender mailSender;

private SimpleMailMessage simpleMailMessage;

/**

* @參數名：@param subject 郵件主題

* @參數名：@param content 郵件主題內容

*/

public void sendMail(String subject, String content, String to) {

simpleMailMessage.setSubject(subject); //設置郵件主題

simpleMailMessage.setTo(to); //設定收件人

simpleMailMessage.setText(content); //設置郵件主題內容

mailSender.send(simpleMailMessage); //發送郵件

}

//Spring 依賴注入

public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {

this.simpleMailMessage = simpleMailMessage;

}

//Spring 依賴注入

public void setMailSender(MailSender mailSender) {

this.mailSender = mailSender;

}

Junit Test：EmailTest.java

package com.fancy.test;

import junit.framework.TestCase;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.fancy.util.Email;

/**

* -----------------------------------------

* @文件: EmailTest.java

* @作者: fancy

* @郵箱: fancydeepin@yeah.net

* @時間: 2012-6-11

* @描述: Junit測試,運行將發送一封email

* -----------------------------------------

*/

public class EmailTest extends TestCase {

public void testSendMail() {

ApplicationContext context = new ClassPathXmlApplicationContext("spring-smtp-mail.xml");

Email mail = (Email)context.getBean("simpleMail");

mail.sendMail("Spring SMTP Mail Subject", "Spring SMTP Mail Text", "fancydeepin@yeah.net");

//mail.sendMail("標題", "內容", "收件人郵箱");

}

EmailAppTest.java 也是一個測試類，跟 Junit 的 EmailTest.java 是幾乎一樣的，這里就不貼出來了，再來看下 Maven：

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<groupId>com.fancy</groupId>

<artifactId>spring-mail-example</artifactId>

<name>spring-mail-example</name>

<url>http://maven.apache.org</url>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

</properties>

<groupId>org.springframework</groupId>

<artifactId>spring</artifactId>

</dependency>

<groupId>javax.mail</groupId>

</dependency>

<groupId>junit</groupId>

<artifactId>junit</artifactId>

</dependency>

</dependencies>

</project>

Run 一下 EmailTest.java，稍等一會就能收到一封 Email

OK，郵件發送成功。另外，在用網易郵箱測試的時候，發現不進行 SMTP驗證郵件也能發送成功，曾在 Shopxx 中提到，
如果是 Gmail 就必須配置SMTP服務器驗證，否則拋出異常，發送會失敗。
