## 1 SpringBoot-quartz基本用法
|
||
|
||
### 添加依赖
|
||
|
||
```xml
|
||
<!-- 实现对 Spring MVC 的自动化配置 -->
|
||
<dependency>
|
||
<groupId>org.springframework.boot</groupId>
|
||
<artifactId>spring-boot-starter-web</artifactId>
|
||
</dependency>
|
||
|
||
<!-- 实现对 Quartz 的自动化配置 -->
|
||
<dependency>
|
||
<groupId>org.springframework.boot</groupId>
|
||
<artifactId>spring-boot-starter-quartz</artifactId>
|
||
</dependency>
|
||
```
|
||
### 创建任务
|
||
创建job
|
||
```java
|
||
@Slf4j
|
||
public class FirstJob extends QuartzJobBean {
|
||
|
||
@Override
|
||
protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
|
||
String now = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").format(LocalDateTime.now());
|
||
log.info("当前的时间: " + now);
|
||
}
|
||
}
|
||
|
||
@Slf4j
|
||
public class SecondJob extends QuartzJobBean {
|
||
|
||
@Override
|
||
protected void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
|
||
String now = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").format(LocalDateTime.now());
|
||
log.info("SecondJob执行, 当前的时间: " + now);
|
||
}
|
||
}
|
||
```
|
||
|
||
|
||
### 创建配置类
|
||
JobDetail&Trigger该方法实现的定时任务，由spring框架启动线程进行调度。用户不需要自己初始化scheduler并启动线程。
|
||
|
||
SimpleScheduleBuilder自动配置
|
||
```java
|
||
@Configuration
|
||
@Service
|
||
public class QuartzConfig {
|
||
|
||
@Bean
|
||
public JobDetail scheduleJobDetail() {
|
||
System.out.println("**************************************** scheduler job begin");
|
||
JobDetail jobDetail = JobBuilder.newJob(SchedulerJob.class)
|
||
.withIdentity("schedulerJob")
|
||
.storeDurably()
|
||
.build();
|
||
System.out.println("**************************************** scheduler job end");
|
||
return jobDetail;
|
||
}
|
||
|
||
@Bean
|
||
public Trigger scheduleJobDetailTrigger() {
|
||
Trigger trigger = TriggerBuilder
|
||
.newTrigger()
|
||
.forJob(scheduleJobDetail())
|
||
.withIdentity("schedulerJob")
|
||
.withSchedule(SimpleScheduleBuilder.simpleSchedule().withRepeatCount(0))
|
||
.startNow()
|
||
.build();
|
||
System.out.println("schedulerJob trigger end");
|
||
return trigger;
|
||
}
|
||
```
|
||
|
||
CronScheduleBuilder手动配置
|
||
|
||
使用ApplicationRunner方法启动了一个线程运行程序。手动创建scheduler加载配置、JobDetail、Trigger然后启动任务。
|
||
```java
|
||
@Component
|
||
public class JobInit implements ApplicationRunner {
|
||
|
||
private static final String ID = "SUMMERDAY";
|
||
|
||
@Autowired
|
||
private Scheduler scheduler;
|
||
|
||
@Override
|
||
public void run(ApplicationArguments args) throws Exception {
|
||
JobDetail jobDetail = JobBuilder.newJob(FirstJob.class)
|
||
.withIdentity(ID + " 01")
|
||
.storeDurably()
|
||
.build();
|
||
CronScheduleBuilder scheduleBuilder =
|
||
CronScheduleBuilder.cronSchedule("0/5 * * * * ? *");
|
||
// 创建任务触发器
|
||
Trigger trigger = TriggerBuilder.newTrigger()
|
||
.forJob(jobDetail)
|
||
.withIdentity(ID + " 01Trigger")
|
||
.withSchedule(scheduleBuilder)
|
||
.startNow() //立即執行一次任務
|
||
.build();
|
||
// 手动将触发器与任务绑定到调度器内
|
||
scheduler.scheduleJob(jobDetail, trigger);
|
||
}
|
||
}
|
||
```
|
||
|
||
|
||
## 2 使用Spring提供的工厂Bean进行配置
