詳細Spring如何進行郵件發送
本文由樂字節Java架構課程獨家贊助播出
環境準備
創建 Maven 項目,在 pom.xml 文件中添加依賴
<!-- spring核心 jar 依賴 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>5.2.4.RELEASE</version>
</dependency>
<!--spring 上下文環境 支持-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>5.2.4.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.2.4.RELEASE</version>
<scope>test</scope>
</dependency>
<!-- Java Mail座標依賴 -->
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>
配置郵件發送 bean
在 spring.xml 配置文件中設置郵件發送對應的bean標籤
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 開啓自動化掃描 -->
<context:component-scan base-package="com.xxxx"/>
<!-- 郵件發送器(提供了郵件發送接口、透明創建Java Mail的MimeMessage、及郵件發送的配置) -->
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="smtp.163.com" />
<property name="port" value="25" />
<property name="defaultEncoding" value="utf-8"></property>
<property name="username" value="用戶名"></property>
<property name="password" value="密碼"></property>
</bean>
<!-- 普通文本郵件對象 -->
<bean id="templateMessage" class="org.springframework.mail.SimpleMailMessage">
<property name="from" value="發件人的郵箱地址" />
<property name="subject" value="spring_mail" />
</bean>
</beans>
定義接口與實現類
定義接口
package com.xxxx.springMail;
/**
* 定義接口
*/
public interface OrderManager {
void placeOrder();
}
定義實現類
package com.xxxx.springMail;
import org.springframework.mail.MailException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSenderImpl;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
@Service
public class SimpleOrderManager implements OrderManager {
@Resource
private JavaMailSenderImpl mailSender;
@Resource
private SimpleMailMessage templateMessage;
@Override
public void placeOrder() {
// 獲取郵件對象
SimpleMailMessage msg = new SimpleMailMessage(this.templateMessage);
// 設置郵件收件人的郵箱地址
msg.setTo("收件人的郵箱地址");
// 設置郵件內容
msg.setText("Hello Spring Mail");
try{
// 發送郵件
this.mailSender.send(msg);
} catch (MailException ex) {
System.err.println(ex.getMessage());
}
}
}
郵件發送測試
/**
* 發送郵件
* @param args
*/
public static void main(String[] args) {
ApplicationContext ac=new ClassPathXmlApplicationContext("spring.xml");
SimpleOrderManager simpleOrderManager =
(SimpleOrderManager) ac.getBean("simpleOrderManager");
simpleOrderManager.placeOrder();
}
發送附件
/**
* 發送包含附件的郵件
* @param args
* @throws MessagingException
*/
public static void main(String[] args) throws MessagingException {
ApplicationContext ac = new ClassPathXmlApplicationContext("spring.xml");
JavaMailSender mailSender= (JavaMailSender) ac.getBean("mailSender");
MimeMessage message= mailSender.createMimeMessage();
message.setSubject("spring_mail"); // 郵件主題
// 創建帶有附件的消息幫組類
MimeMessageHelper helper = new MimeMessageHelper(message,true,"utf-8");
helper.setTo(new InternetAddress("收件人的郵箱地址"));//設置接收人
helper.setText("Thank you for ordering!"); // 郵件內容
helper.setFrom("發件人的郵箱地址"); // 發件人
// 設置附件
File file = new File("C:\\work\\郵件附件.txt");
// 添加附件
helper.addAttachment(file.getName(), file);
// 發送郵件
mailSender.send(message);
}
