异步发送邮件总结

异步发送邮件总结

使用activeMQ实现异步发送邮件：创建两个maven项目，一个叫activemq-provider，一个叫activemq-consumer；activemq-consumer项目启动后，一直处于消息监听状态，activemq-provider发送一条邮件信息，activemq-consumer接收消息，调用接口向邮件服务器发邮件。在项目中直接调用activemq-provider的发送邮件的接口就可以异步发送邮件了。
软件安装：apache-activemq-5.11.1-bin
windows:解压后：我电脑是64位的，双击apache-activemq-5.11.1/bin/win64/activemq启动mq服务；如果是32位的，双击apache-activemq-5.11.1/bin/win32/activemq启动mq服务。
linux：安装activemq，自行百度。或者参考：https://www.cnblogs.com/linjunwei2017/ p/7850757.html
开始撸代码：
1，生产者：

2）实体类：

package bhz.entity;
public class Mail {
/** 发件人 **/
private String from;
/** 收件人 **/
private String to;
/** 主题 **/
private String subject;
/** 邮件内容 **/
private String content;

public Mail(){}

public Mail(String from, String to, String subject, String content) {
super();
this.from = from;
this.to = to;
this.subject = subject;
this.content = content;
}

public String getFrom() {
return from;
}
public void setFrom(String from) {
this.from = from;
}
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;
}
}

3）使用spring帮我们写好的jmsTemplate来异步发送消息
package bhz.mq;
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 bhz.entity.Mail;
import com.alibaba.fastjson.JSONObject;

@Service("mqProducer")
public class MQProducer {

private JmsTemplate jmsTemplate;

public JmsTemplate getJmsTemplate() {
return jmsTemplate;
}

@Autowired
public void setJmsTemplate(JmsTemplate jmsTemplate) {
this.jmsTemplate = jmsTemplate;
}

public void sendMessage(final Mail mail) {
jmsTemplate.send(new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(JSONObject.toJSONString(mail));
}
});
}
}

4）配置文件（存放到项目的resources目录下）
config.properties：
## ActiveMQ Config
activemq.brokerURL=tcp\://localhost\:61616
activemq.userName=renpl
activemq.password=renpl123
activemq.pool.maxConnections=10
#queueName
activemq.queueName=mailqueue

5)测试类：
package bhz.test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import bhz.mq.MQProducer;

@ContextConfiguration(locations = {"classpath:spring-context.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
public class TestProducer {

@Autowired
private MQProducer mqProducer;

@Test
public void send(){
Mail mail = new Mail();
mail.setFrom("[email protected]");
mail.setTo("[email protected]");
mail.setSubject("异步发送邮件");
mail.setContent("您好：这是我用程序调用网易服务器想你发送的邮件");

this.mqProducer.sendMessage(mail);
System.out.println("发送成功..");

}

}
