spring和quartz整合实现定时任务(配置文件配置方式

在开发的时候遇到一个问题，就是需要定时的去扫描数据库中表的数据，当时就考虑到了利用quartz去实现。

实现的是定时的去发送邮件的任务，设计的时候有三张表，一张是需要扫描的表email，一张是发送成功的表emailSuccess，还有一张表是发送失败的表emailFail，失败表中还记录的了发送失败的原因。扫描表的时候如果发送成功则将记录插入到成功表，并删除扫描中的记录，失败也是同样的道理。

maven工程中首先导入以下依赖：

<span style="white-space:pre">		</span><dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>

<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>2.2.1</version>
</dependency>

代码如下：

public class JobMailMessageService{

private static final Logger logger = LoggerFactory.getLogger(JobMailMessageService.class);

@Autowired
IMcMessageService mcMessageService;
@Autowired
IMcBasEmailService basMcEmailService;
@Autowired
IMcBasEmailFailService basMcEmailFailService;
@Autowired
IMcBasEmailSuccessService basMcEmailSuccessService;

public void sendMcEmailJob() {

List<McBasEmail> list = basMcEmailService.findBySendTimeStatus(new Date());//查询数据，相当于扫描表

if(list != null && list.size() > 0){
logger.info("Send Email task execution start time:" + new MyDate() + " Information number：" + list.size());

try{
Iterator<McBasEmail> iter = list.iterator();
McBasEmail bMessage = new McBasEmail();
while (iter.hasNext()){
bMessage = iter.next();//待发送邮件

int returnFlag = mcMessageService.sendEmail(bMessage.getReceiver(), bMessage.getSubject(), bMessage.getContent());

if(returnFlag == 1){

McBasEmailSuccess bSuccess = new McBasEmailSuccess(bMessage.getReceiver(), bMessage.getSubject(), bMessage.getContent(), bMessage.getKey(),
2L, bMessage.getGrpId(),  bMessage.getTaskType(), bMessage.getSendTime(), bMessage.getCreateTime(), null);
basMcEmailSuccessService.create(bSuccess);
basMcEmailService.delete(bMessage);
} else {

McBasEmailFail bFail = new McBasEmailFail(bMessage.getReceiver(), bMessage.getSubject(), bMessage.getContent(), bMessage.getKey(),
3L, bMessage.getGrpId(), bMessage.getTaskType(), "", bMessage.getSendTime(), new Date(), null);
basMcEmailFailService.create(bFail);
basMcEmailService.delete(bMessage);
}
}
}catch (Exception e){
e.printStackTrace();
logger.error(e.getMessage(), e);
}
logger.info("Send Email to perform a task over:" + new MyDate());
}
}

}
