下面是Spring Boot整合Quartz的基本步骤:
1. 添加依赖:在pom.xml文件中添加Quartz和Spring Boot Starter Quartz的依赖。
```xml
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.3.2</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
```
2. 创建Job类:创建一个实现了org.quartz.Job接口的Job类,实现Job接口的execute方法。
```java
public class MyJob implements Job {
@Override
public void execute(JobExecutionContext context) throws JobExecutionException {
// Job执行的具体逻辑
}
}
```
3. 创建Trigger和JobDetail:创建JobDetail和Trigger,并将JobDetail和Trigger绑定在一起。
```java
// 创建JobDetail实例,并指定任务名称、组名、以及任务执行类
JobDetail job = JobBuilder.newJob(MyJob.class).withIdentity("job1", "group1").build();
// 创建Trigger实例,每秒钟执行一次
Trigger trigger = TriggerBuilder.newTrigger().withIdentity("trigger1", "group1").startNow()
.withSchedule(SimpleScheduleBuilder.simpleSchedule().withIntervalInSeconds(1).repeatForever()).build();
// 将Job和Trigger关联起来
scheduler.scheduleJob(job, trigger);
```
4. 配置SchedulerFactoryBean:配置SchedulerFactoryBean,使得Spring Boot能够自动注入SchedulerFactoryBean实例。
```java
@Configuration
public class SchedulerConfig {
@Autowired
private JobFactory jobFactory;
@Bean
public SchedulerFactoryBean schedulerFactoryBean() {
SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
schedulerFactoryBean.setJobFactory(jobFactory);
return schedulerFactoryBean;
}
@Bean
public Scheduler scheduler() {
return schedulerFactoryBean().getScheduler();
}
}
```
5. 启动应用程序:在Spring Boot应用程序启动后,SchedulerFactoryBean实例会自动启动,开始执行定时任务。
```java
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
```
以上就是Spring Boot整合Quartz的基本步骤。
