前段时间刚把工作任务做完，闲来无事，到网上看看资料，发现自己对java quartz定时任务和java发送邮件挺感兴趣，于是借鉴网上的列子写了一个简单的Demo(Maven工程)，使用SPRing整合quartz实现定时任务，使用java mail实现发送邮件
1. 定时任务的实现
1.1 导jar包，pom.xml中的相关配置如下
<!-- 使用国内的maven仓库 --> <repositories> <repository> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories> <dependencies> <!-- 日志框架jar包依赖 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.6.6</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.6</version> </dependency> <!-- spring和quartz的jar包依赖 --> <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>3.2.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>3.2.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>3.2.4.RELEASE</version> </dependency> <!-- java mail的jar包 --> <dependency> <groupId>javax.mail</groupId> <artifactId>javax.mail-api</artifactId> <version>1.4.7</version> </dependency> <dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.5.3</version> </dependency>1.2 写一个调度器要执行的任务内容的类
public class SendMailScheduler { private static final Logger LOG = Logger.getLogger(SendMailScheduler.class); public void work() { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); LOG.debug(sdf.format(new Date())); }}1.3 在spring容器中配置quartz1.3.1 实现JobDetail
<!-- 第二种方式实现JobDetail 普通类 --> <bean id="Quartz" class="com.formssi.spring_quartz.SendMailScheduler"></bean> <bean id="JobDetail2" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <property name="targetObject" ref="Quartz"></property> <property name="targetMethod" value="work"></property> </bean>1.3.2 配置触发器Trigger<!-- 触发器的第二种方式 CRON表达式 --> <bean id="trigger2" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean"> <property name="jobDetail" ref="JobDetail2"></property> <!-- 一下配置是每15秒发送执行一次任务 --> <property name="cronExpression" value="0/15 * * * * ?"></property> </bean>1.3.3 配置调度器
<!-- 把触发器加入到任务列表中 --> <bean id="testScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="trigger2" /> </list> </property> </bean>1.4 测试任务调度的配置结果（Log4J的配置略过）
2. 实现邮件发送
2.2 写发送邮件的类，具体看注释
public class SendMail { private static final Logger LOG = Logger.getLogger(SendMail.class); private String host = ""; // smtp服务器 private String from = ""; // 发件人地址 private String to = ""; // 收件人地址 private String[] attachmentPath = null; // 附件地址 private String user = ""; // 用户名 private String pwd = ""; // 密码 private String subject = ""; // 邮件标题 private int status = 0; // 发送结果：0-成功，1-失败 private String htmlContent = ""; //若果发送的是html格式的邮件，这是html内容 private static final Logger logger = Logger.getLogger(SendMail.class); public void setAddress(String from, String to, String subject) { this.from = from; this.to = to; this.subject = subject; } public void setAttachmentPath(String[] attachmentPath) { this.attachmentPath = attachmentPath; } public void setHtmlContent(String htmlContent) { this.htmlContent = htmlContent; } public int sendMail(String user, String pwd, String host) { // 1. 创建参数配置, 用于连接邮件服务器的参数配置 Properties prop = new Properties(); prop.put("mail.smtp.host", host); prop.put("mail.smtp.auth", "true"); prop.put("mail.smtp.port","25"); prop.put("mail.transport.protocol", "smtp"); // 2. 根据配置创建会话对象, 用于和邮件服务器交互 session session = Session.getInstance(prop); session.setDebug(true); MimeMessage message = new MimeMessage(session); try { //设置发件人地址 message.setFrom(new InternetAddress(from)); //设置收件人地址 message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));// message.setRecipient(Message.RecipientType.TO, new InternetAddress(to)); //设置邮件标题 message.setSubject(subject); Multipart mp = new MimeMultipart(); // 设置邮件的文本内容 BodyPart bodyPart = new MimeBodyPart(); //邮件正文（html形式） bodyPart.setContent(htmlContent, "text/html; charset=utf-8"); mp.addBodyPart(bodyPart); //设置邮件附件 for (String filePath:attachmentPath) { bodyPart= new MimeBodyPart(); File attachment = new File(filePath); if (!attachment.exists()) { LOG.warn("文件:"+attachment+"不存在！"); status = 1; return status; } else{ DataSource ds = new FileDataSource(attachment); bodyPart.setDataHandler(new DataHandler(ds)); // 添加附件的标题 // 这里很重要，通过下面的Base64编码的转换可以保证你的中文附件标题名在发送时不会变成乱码 sun.misc.BASE64Encoder enc = new sun.misc.BASE64Encoder(); bodyPart.setFileName("=?GBK?B?" + enc.encode(attachment.getName().getBytes()) + "?="); mp.addBodyPart(bodyPart); message.setContent(mp); } } message.saveChanges(); //创建Transport对象 Transport transport = session.getTransport("smtp"); //连接服务器 transport.connect(host, user, pwd); //发送邮件 transport.sendMessage(message, message.getAllRecipients()); transport.close(); } catch (Exception e) { e.printStackTrace(); logger.error("发送失败！"); } return status; }}2.2 在任务类中调用发送邮件的方法
public class SendMailScheduler { private static final Logger LOG = Logger.getLogger(SendMailScheduler.class); public void work() { SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); LOG.debug(sdf.format(new Date())); SendMail sendmail = new SendMail(); //设置发件地址和收件地址及主题 sendmail.setAddress("1300880****@163.com", "huang**o@formssi.com", "哈哈！逗你玩！"); //设置附件 sendmail.setAttachmentPath(new String[]{"D:/logs/test.log", "D:/picture/test.PNG"}); //设置html内容 StringBuffer content = new StringBuffer(); content.append("<!DOCTYPE html PUBLIC /"-//W3C//DTD HTML 4.01 Transitional//EN/" /"http://www.w3.org/TR/html4/loose.dtd/">") .append("<html>") .append("<head>") .append("<meta http-equiv=/"Content-Type/" content=/"text/html; charset=UTF-8/">") .append("<title>测试邮件</title>") .append("<body>") .append("<h2>尊敬的xxx,您好,您需要的信息如下：</h2>") .append("<ol>") .append("<li>xxxxx1</li>") .append("<li>xxxxx2</li>") .append("<li>xxxxx2</li>") .append("</ol>") .append("</body>") .append("</head>") .append("</html>"); sendmail.setHtmlContent(content.toString()); //调用发送邮件方法 int status = sendmail.sendMail("13008807015", "********", "smtp.163.com"); if (status == 1) { LOG.error("发送失败"); } else { LOG.info("发送成功"); } }}2.3 测试发送结果下载Demo链接：点击打开链接
