■一、数据库表数据备份
此处的数据库表数据备份指的并不是整个数据库的数据备份，而是针对某些数据量比较大的业务表的历史数据备份。数据库中基础表、用户表、字典表等等表的数据量都是非常小的，只有个别业务表因业务操作频繁数据量巨大。假如我们的业务表并不需要保存过长时间的业务数据时，可以将一定期限前的数据保存到历史表中。这样业务表中数据量就能够保持到一个合理水平，从而提高该业务表的查询效率。

1.在数据备份时我们需要解决以下几个问题。
1)由于我们的数据备份是通过每天的定时任务完成的，如果其中某些天程序没有执行，那么后续的定时任务要把前面没有执行的数据处理掉。
2)业务表的主键ID是通过PostgreSQL的sequence生成的。这就存在一个问题当sequence达到最大值后，他将重新从1开始取值。这个特殊的数据变化也要在程序中处理掉。
2.处理逻辑设计
1)每天需要将业务表中最小id和最大id放入【历史数据(wdi_history)】中。
每天0点时获取业务表的最大id，并将该id作为昨天的最大id和今天的最小id更新到【历史数据】表中。
插入历史数据表数据有以下几种情况：
2)备份数据只需要处理15天前的业务数据 最小id->最大id。
3)删除历史表中180天以前的数据。
■三、代码实现
1)定时任务配置类
package infosky.wdis.task;
import org.quartz.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* 配置定时任务
*/
@Configuration
public class QuartzConfig {
/**
* 使用jobDetail包装job
* @return
*/
@Bean
public JobDetail backupJobDetail(){
return JobBuilder.newJob(BackupJob.class).withIdentity("backupJob").storeDurably().build();
}
/**
* 把jobDetail注册到Cron表达式的trigger上去
* @return
*/
@Bean
public Trigger backupJobCronTrigger(){
CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule("1 0 0 * * ?");
return TriggerBuilder.newTrigger()
.forJob(backupJobDetail())
.withIdentity("backupJobCronTrigger")
.withSchedule(cronScheduleBuilder)
.build();
}
}
2)数据备份类
