QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)

原来有个教程是关于Javamail的,但是那个是自己写Javamail的发送过程,这次不同的是:使用Spring的Mail功能,使用了消息队列。

先看一下设想的场景

QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)

不过本文重点不是消息队列,而是使用spring发送邮件。

首先针对于不会Maven和消息队列的小盆友们

依赖jar包:

spring系列jar包

Javamail

先建立一个封装Mail信息的类:很好理解,里面的成员变量代表(收件人,主题,内容)

package com.mq.entity;

import java.io.Serializable;

public class MailInfo implements Serializable {

    /**
*
*/
private static final long serialVersionUID = -5853264487189248317L;
private String to;
private String subject;
private String content;
public MailInfo() {
}
public MailInfo(String to, String subject, String content) {
this.to = to;
this.subject = subject;
this.content = content;
}
public String getTo() {
return to;
}
public void setTo(String to) {
this.to = to;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
} }

然后呢,在classpath下面整一个属性文件,email.properties

mail.account=用户名
mail.pass=密码
mail.host=smtp.exmail.qq.com
mail.port=465
mail.protocol=smtp mail.debug=true
mail.smtp.auth=true
mail.smtp.ssl.enable=true

注意:企业邮箱不用什么授权码,就是密码

然后classpath下建立spring配置文件。

<?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"

</property>
</bean> <bean id="simpleMailMessage" class="org.springframework.mail.SimpleMailMessage">

</bean> <bean id="threadPoolTaskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
<!-- 线程池维护线程的最少数量 -->
<property name="corePoolSize" value="5" />
<!-- 线程池维护线程的最大数量 -->
<property name="maxPoolSize" value="20" />
<!-- 线程池维护线程所允许的空闲时间 -->
<property name="keepAliveSeconds" value="30000" />
<!-- 线程池所使用的缓冲队列 -->
<property name="queueCapacity" value="1000" />
</bean> </beans>

然后写一个发送邮件类

package com.mq.mail;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.stereotype.Component; import com.mq.entity.MailInfo; @Component
public class SendMail { @Autowired
private JavaMailSender javaMailSender;
@Autowired
private SimpleMailMessage simpleMailMessage;
@Autowired
private ThreadPoolTaskExecutor threadPoolTaskExecutor; public void send(final MailInfo mailInfo){
threadPoolTaskExecutor.execute(new Runnable() { @Override
public void run() {
try {
simpleMailMessage.setTo(mailInfo.getTo());
simpleMailMessage.setSubject(mailInfo.getSubject());
simpleMailMessage.setText(mailInfo.getContent());
javaMailSender.send(simpleMailMessage);
} catch (Exception e) {
e.printStackTrace();
}
}
});
} }

最后写一个测试类:

package com.mq.test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.mq.entity.MailInfo;
import com.mq.mail.SendMail; public class TestMail { public static void main(String[] args) {
ClassPathXmlApplicationContext app = new ClassPathXmlApplicationContext("classpath:spring-mail.xml");
app.start();
MailInfo mailInfo = new MailInfo("XXX@qq.com", "这是主题", "这是内容");
app.getBean(SendMail.class).send(mailInfo);
app.close();
}
}

结果:

QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)

下面是Maven+消息队列的部分

我有两个工程,一个是生产者,一个是消费者。都是Maven的web工程。PS:这两个工程加入了mvc,因为本来想做个好玩的东西的,但是太忙了,先放下了,目前只有利用消息队列发送邮件的部分。这也是为啥依赖这么多的原因。

首先是生产者

建立ActiveMQ的属性文件:activemq.properties

activemq.brokerUrl=tcp://localhost:61616
activemq.userName=admin
activemq.password=admin
activemq.pool.maxConnection=10 activemq.queueName=foodQueue
activemq.topicName=foodTopic

因为是本地测试,我就在windows系统启动了一个ActiveMQ。

下面建立spring-activemq.xml

<?xml version="1.0" encoding="UTF-8"?>

</beans>

接下来写代码,目录结构如下:(你不需要考虑controller,以及spring-mvc.xml,以及Food)

QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)

建立Mail信息类:

package com.mq.entity;

import java.io.Serializable;

public class MailInfo implements Serializable {

    /**
*
*/
private static final long serialVersionUID = -5853264487189248317L;
private String to;
private String subject;
private String content;
public MailInfo() {
}
public MailInfo(String to, String subject, String content) {
this.to = to;
this.subject = subject;
this.content = content;
}
public String getTo() {
return to;
}
public void setTo(String to) {
this.to = to;
}
public String getSubject() {
return subject;
}
public void setSubject(String subject) {
this.subject = subject;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
} }

关于那个Food是我测试着玩的哈哈,满足你的好奇心

package com.mq.entity;

import java.io.Serializable;
import java.util.Date; public class Food implements Serializable { private static final long serialVersionUID = 1L; private String foodName;
private double foodPrice;
private int foodNumber;
private Date orderTime;
public Food() {
}
public Food(String foodName, double foodPrice, int foodNumber, Date orderTime) {
super();
this.foodName = foodName;
this.foodPrice = foodPrice;
this.foodNumber = foodNumber;
this.orderTime = orderTime;
}
public String getFoodName() {
return foodName;
}
public void setFoodName(String foodName) {
this.foodName = foodName;
}
public double getFoodPrice() {
return foodPrice;
}
public void setFoodPrice(double foodPrice) {
this.foodPrice = foodPrice;
}
public int getFoodNumber() {
return foodNumber;
}
public void setFoodNumber(int foodNumber) {
this.foodNumber = foodNumber;
}
public Date getOrderTime() {
return orderTime;
}
public void setOrderTime(Date orderTime) {
this.orderTime = orderTime;
}
@Override
public String toString() {
return "Food [foodName=" + foodName + ", foodPrice=" + foodPrice + ", foodNumber=" + foodNumber + ", orderTime="
+ orderTime + "]";
} }

消息服务接口

package com.mq.service;

import javax.jms.Destination;

import org.springframework.stereotype.Service;

import com.mq.entity.Food;
import com.mq.entity.MailInfo; @Service
public interface HelloService { void sendMessage(Destination destination, Food food); void sendMail(Destination destination, MailInfo mail);
}

消息服务实现:

package com.mq.service.impl;

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session; import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service; import com.alibaba.fastjson.JSONObject;
import com.mq.entity.Food;
import com.mq.entity.MailInfo;
import com.mq.service.HelloService; @Service
public class HelloServiceImpl implements HelloService { @Autowired
private JmsTemplate jmsTemplate; @Override
public void sendMessage(Destination destination, Food food){
jmsTemplate.send(destination, new MessageCreator() { @Override
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(JSONObject.toJSONString(food));
// return session.createObjectMessage(new Food("蛋糕", 66.5, 1, new Date()));
}
});
} @Override
public void sendMail(Destination destination, MailInfo mail) {
jmsTemplate.send(destination, new MessageCreator() { @Override
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(JSONObject.toJSONString(mail));
}
});
} }

最后是测试类,这里使用了springTest。

package com.mq.test;

import javax.jms.Destination;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.mq.entity.MailInfo;
import com.mq.service.HelloService; @ContextConfiguration(locations={"classpath:spring.xml"})
@RunWith(SpringJUnit4ClassRunner.class)
public class MyTest { //@Autowired与@Resource都可以用来装配bean. 都可以写在字段上,或写在setter方法上。 //使用@Autowired的话,想使用名称装配可以结合@Qualifier注解进行使用 //@Resource(这个注解属于J2EE的),默认安照名称进行装配,名称可以通过name属性进行指定,
//如果没有指定name属性,当注解写在字段上时,默认取字段名进行按照名称查找,如果注解写在setter方法上默认取属性名进行装配。 @Autowired
private HelloService helloService; @Autowired
@Qualifier("queueDestination")
private Destination destination; @Test
public void test(){
//helloService.sendMessage(destination, new Food("蛋糕", 66.5, 1, new Date()));
for (int i = 0; i < 1; i++) {
helloService.sendMail(destination, new MailInfo("XXX@qq.com", "Spring java mail"+i, "生产者-消息队列-消费者-spring-mail"));
}
}
}

下面是消费者:

依赖和生产者一样的,这里不重复了。activemq.properties也一样。

邮箱属性文件:

mail.account=用户名
mail.pass=密码
mail.host=smtp.exmail.qq.com
mail.port=465
mail.protocol=smtp mail.debug=true
mail.smtp.auth=true
mail.smtp.ssl.enable=true

下面是工程结构:entity不说了,是一样的。

QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)

ActiveMQ监听器:

package com.mq.listener;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage; import org.springframework.beans.factory.annotation.Autowired; import com.alibaba.fastjson.JSONObject;
import com.mq.entity.MailInfo;
import com.mq.mail.SendMail; public class ActiveMQListener implements MessageListener { @Autowired
private SendMail sendMail; @Override
public void onMessage(Message message) {
TextMessage text = (TextMessage) message; try {
MailInfo mail = JSONObject.parseObject(text.getText(), MailInfo.class);
if(mail != null){
System.out.println(mail.getTo() + "," + mail.getSubject() + "," + mail.getContent());
System.out.println("发送邮件...");
sendMail.send(mail);
}
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} // try {
// System.out.println(text.getText());
// Food food = JSONObject.parseObject(text.getText(), Food.class);
// System.out.println("============收到消息===========");
// System.out.println(food);
// } catch (JMSException e) {
// e.printStackTrace();
// } } }

SendMail:

package com.mq.mail;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.stereotype.Component; import com.mq.entity.MailInfo; @Component
public class SendMail { @Autowired
private JavaMailSender javaMailSender;
@Autowired
private SimpleMailMessage simpleMailMessage;
@Autowired
private ThreadPoolTaskExecutor threadPoolTaskExecutor; public void send(final MailInfo mailInfo){
threadPoolTaskExecutor.execute(new Runnable() { @Override
public void run() {
try {
simpleMailMessage.setTo(mailInfo.getTo());
simpleMailMessage.setSubject(mailInfo.getSubject());
simpleMailMessage.setText(mailInfo.getContent());
javaMailSender.send(simpleMailMessage);
} catch (Exception e) {
e.printStackTrace();
}
}
});
} }

最后测试:

package com.mq.test;

import javax.jms.Destination;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @ContextConfiguration(locations={"classpath:spring.xml"})
@RunWith(SpringJUnit4ClassRunner.class)
public class MyTest { //@Autowired与@Resource都可以用来装配bean. 都可以写在字段上,或写在setter方法上。 //使用@Autowired的话,想使用名称装配可以结合@Qualifier注解进行使用 //@Resource(这个注解属于J2EE的),默认安照名称进行装配,名称可以通过name属性进行指定,
//如果没有指定name属性,当注解写在字段上时,默认取字段名进行按照名称查找,如果注解写在setter方法上默认取属性名进行装配。 @Autowired
@Qualifier("queueDestination")
private Destination destination; @Test
public void test(){
try {
Thread.sleep(Integer.MAX_VALUE);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//在单元测试里,如果test方法先于我们要执行的任务结束,会导致任务出错,所以我们这里睡眠了MAX秒,就为了给我们的任务争取时间
}
}

先启动ActiveMQ,然后执行生产者的test方法,

QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)

然后执行消费者的test方法。

QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)

结果:

QQ企业邮箱+Spring+Javamail+ActiveMQ(发送企业邮件)
