爱威尔-spring + spring mvc +email(邮件发送)支持同步异步配置

利用spring配置文件方式发送邮件支持同步和异步，在网上看了好多都不靠谱，今天测试通过，记录一下，有坑请注意。 
 先看spring.xml这个配置文件： 
 
<pre class="prettyprint lang-xml">true</pre> 重点看我用 标注掉的，看了好多网上都是这样配置的，可是我一个也测试通过，后来把这些去掉了反而可以了。这就是坑。 
 
 再看spring-mvc.xml： 
 
<pre class="prettyprint lang-xml"></pre> 然后就是com.aurora.tingji.service.impl.MailServiceImpl： 
 
 
<pre class="prettyprint lang-java">package com.aurora.tingji.service.impl;

import java.io.IOException;

import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.core.task.TaskExecutor;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;

import com.aurora.tingji.service.MailService;
import com.aurora.tingji.vo.Email;

public class MailServiceImpl implements MailService {

private JavaMailSender mailSender;// 注入Spring封装的javamail
	private TaskExecutor taskExecutor;// 注入Spring封装的异步执行器

public void sendMail(Email email) throws MessagingException, IOException {
		sendMailBySynchronizationMode(email);
		
		/*MimeMessage mime = mailSender.createMimeMessage();
		MimeMessageHelper helper = new MimeMessageHelper(mime, true, "utf-8");
		helper.setFrom(email.getFromAddress());// 发件人
		helper.setTo(email.getToAddress());// 收件人
		helper.setReplyTo(email.getFromAddress());// 回复到
		helper.setSubject(email.getSubject());// 邮件主题
		helper.setText(email.getContent(), true);// true表示设定html格式
		mailSender.send(mime);
		System.out.println("9======================");*/
	}

public void sendMailByAsynchronousMode(final Email email) {
		taskExecutor.execute(new Runnable() {
			public void run() {
				try {
					sendMailBySynchronizationMode(email);
				} catch (MessagingException e) {
					e.printStackTrace();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		});
	}

public void sendMailBySynchronizationMode(Email email)
			throws MessagingException, IOException {
		MimeMessage mime = mailSender.createMimeMessage();
		MimeMessageHelper helper = new MimeMessageHelper(mime, true, "utf-8");
		helper.setFrom(email.getFromAddress());// 发件人
		helper.setTo(email.getToAddress());// 收件人
		helper.setReplyTo(email.getFromAddress());// 回复到
		helper.setSubject(email.getSubject());// 邮件主题
		helper.setText(email.getContent(), true);// true表示设定html格式
		mailSender.send(mime);
		System.out.println("9======================");
	}

public void setMailSender(JavaMailSender mailSender) {
		this.mailSender = mailSender;
	}

public void setTaskExecutor(TaskExecutor taskExecutor) {
		this.taskExecutor = taskExecutor;
	}

public JavaMailSender getMailSender() {
		return mailSender;
	}

public TaskExecutor getTaskExecutor() {
		return taskExecutor;
	}

}
</pre> 接口自己写，这里不再贴出来了。 
 
 下面是： 
 
<pre class="prettyprint lang-java">package com.aurora.tingji.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.aurora.tingji.service.MailService;
import com.aurora.tingji.vo.Email;

@Controller
public class MailController {

private MailService mailService;

@RequestMapping(value="/email/send")
	public void postSendMail(final Model model, final HttpServletRequest request, 
			final HttpServletResponse response) {
		
		Email email = new Email();
		email.setToAddress("815726208@qq.com");
		email.setFromAddress("634623907@qq.com");
		email.setSubject("正在注册账户");
		email.setContent("正在注册账户，您的激活码为xxxxxx");
		try {
			mailService.sendMail(email);
			System.out.println("发送邮件");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

public MailService getMailService() {
		return mailService;
	}

public void setMailService(MailService mailService) {
		this.mailService = mailService;
	}
}
</pre> 
 
<pre class="prettyprint lang-java">package com.aurora.tingji.vo;

public class Email {

/** 发件人 **/
	private String fromAddress;
	
	/** 收件人 **/
	private String toAddress;

/** 邮件主题 **/
	private String subject;

/** 邮件内容 **/
	private String content;

public String getFromAddress() {
		return fromAddress;
	}

public void setFromAddress(String fromAddress) {
		this.fromAddress = fromAddress;
	}

public String getToAddress() {
		return toAddress;
	}

public void setToAddress(String toAddress) {
		this.toAddress = toAddress;
	}

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;
	}
}
</pre> 最后qq邮件服务端设置： 
 
 <img src="79/20161208164948_146.png" alt=""> 
 true 最后你会发现就配置这些就可以了 
 mail.host=smtp.qq.com 
 我看网上几乎所有的都多余了，而且没有一个运行成功的，真是扯淡。
