java - 如何在beanfactory中注册bean？

Question

我试图拥有多个 JobDetailFactoryBean、CronTriggerFactoryBean 和 SchedulerFactoryBean。我怎样才能将这个bean注册到beanfactory？我正在使用 Spring Boot。

@Configuration
@ComponentScan("uk.co.themoderngeek.quartz.speakingclock")
public class QuartzConfiguration {

    @Autowired
    private DataSource dataSource;

    @Value("${quartz.db.username}")
    private String username;

    @Value("${quartz.db.password}")
    private String password;

    public QuartzConfiguration() {
        // TODO Auto-generated constructor stub
        JobDetailFactoryBean j1 = jobDetailFactoryBeanCreator("group1","job1");
        CronTriggerFactoryBean c1 = cronTriggerFactoryBeanCreator(j1, "0 0/2 * 1/1 * ? *");
        SchedulerFactoryBean s1 = schedulerFactoryBeanCreator(c1);

        JobDetailFactoryBean j2 = jobDetailFactoryBeanCreator("group2","job2");
        CronTriggerFactoryBean c2 = cronTriggerFactoryBeanCreator(j2, "0 0/2 * 1/1 * ? *");
        SchedulerFactoryBean s2 = schedulerFactoryBeanCreator(c2);

        JobDetailFactoryBean j3 = jobDetailFactoryBeanCreator("group3","job3");
        CronTriggerFactoryBean c3 = cronTriggerFactoryBeanCreator(j3, "0 0/2 * 1/1 * ? *");
        SchedulerFactoryBean s3 = schedulerFactoryBeanCreator(c3);
    }

   @Bean
    public JobDetailFactoryBean jobDetailFactoryBeanCreator(String group, String name){
        JobDetailFactoryBean factory = new JobDetailFactoryBean();
        factory.setJobClass(SpeakingClockJob.class);
        factory.setGroup(group);
        factory.setName(name);
        return factory;
    }

   @Bean
    public CronTriggerFactoryBean cronTriggerFactoryBeanCreator(JobDetailFactoryBean bean, String cron){
        CronTriggerFactoryBean stFactory = new CronTriggerFactoryBean();
        stFactory.setJobDetail(bean.getObject());
        stFactory.setStartDelay(3000);
        stFactory.setCronExpression(cron);
        return stFactory;
    }

   @Bean
    public SchedulerFactoryBean schedulerFactoryBeanCreator(CronTriggerFactoryBean ct) {
        SchedulerFactoryBean scheduler = new SchedulerFactoryBean();
        scheduler.setTriggers(ct.getObject());
        scheduler.setDataSource(dataSource);
        scheduler.setConfigLocation(new ClassPathResource("application.properties"));
        return scheduler;
    }


    @Bean
    public DriverManagerDataSource dataSource() {
        DriverManagerDataSource data = new DriverManagerDataSource();
        data.setDriverClassName("com.mysql.jdbc.Driver");
        data.setUrl("jdbc:mysql://localhost:3306/quartz");
        data.setUsername("name");
        data.setPassword("password");
        return data;
    }

当我运行上面的代码时，我收到此错误。我如何动态创建 JobDetailFactoryBean、CronTriggerFactoryBean 和 SchedulerFactoryBean 因为当我必须添加任何作业时，我必须创建这些 bean 来执行作业，所以我想动态创建它。

java.lang.IllegalStateException:BeanFactory尚未注入(inject)@Configuration类

我不知道我是否理解你的要求，但是你可以用不同的属性声明你想要的所有bean，只需更改方法名称即可。例如:

@Bean
public JobDetailFactoryBean jobDetailFactoryBeanOne(){
    JobDetailFactoryBean factory = new JobDetailFactoryBean();
    factory.setJobClass(SpeakingClockJob.class);
    factory.setGroup("group1");
    factory.setName("job1");
    return factory;
}

然后你必须像这样使用@Autowired:

@Autowired
private JobDetailFactoryBean jobDetailFactoryBeanOne;

或

@Autowired
@Qualifier("jobDetailFactoryBeanOne")
private JobDetailFactoryBean nameWhatYouWant;
