独有的Spring profiled bean和DependsOn注释

适用于我的代码:
数据库配置的一部分如下所示:

@Profile("!dbClean")
@Bean(initMethod = "migrate")
public Flyway flywayNotADestroyer() {
    Flyway flyway = new Flyway();
    flyway.setDataSource(dataSource());
    flyway.setInitOnMigrate(true);
    return flyway;
}

@Profile("dbClean")
@Bean(initMethod = "migrate")
public Flyway flywayTheDestroyer() {
    Flyway flyway = new Flyway();
    flyway.setDataSource(dataSource());
    flyway.setInitOnMigrate(true);
    flyway.clean();
    return flyway;
}

配置代表两个独占bean。当存在“dbClean”配置文件时创建一个,而当不存在时创建另一个配置文件。忍受我,忘记代码重复。

另一种配置管理Quartz配置:

@Autowired
private Flyway flyway;

@Bean
public SchedulerFactoryBean quartzScheduler(Flyway flyway) throws SchedulerException {
    SchedulerFactoryBean quartzScheduler = new SchedulerFactoryBean();

    quartzScheduler.setDataSource(dataSource);
    quartzScheduler.setTransactionManager(transactionManager);
    quartzScheduler.setOverwriteExistingJobs(true);
    quartzScheduler.setSchedulerName("mysuperduperthegratest-quartz-scheduler");

    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
    jobFactory.setApplicationContext(applicationContext);
    quartzScheduler.setJobFactory(jobFactory);
    quartzScheduler.setQuartzProperties(schedulingProperties);

    return quartzScheduler;
}

上面的作品就像一个魅力。问题是Quartz配置没有使用Flyway自动装配的bean。它只需要比Quartz调度程序更早创建这个bean。

所以理想的配置是:

db部分:

@Profile("!dbClean")
@Bean(name = "flyway", initMethod = "migrate")
public Flyway flywayNotADestroyer() {
    Flyway flyway = new Flyway();
    flyway.setDataSource(dataSource());
    flyway.setInitOnMigrate(true);
    return flyway;
}

@Profile("dbClean")
@Bean(name = "flyway", initMethod = "migrate")
public Flyway flywayTheDestroyer() {
    Flyway flyway = new Flyway();
    flyway.setDataSource(dataSource());
    flyway.setInitOnMigrate(true);
    flyway.clean();
    return flyway;
}

Quartz部分:

@Bean
@DependsOn({"flyway"})
public SchedulerFactoryBean quartzScheduler() throws SchedulerException {
    SchedulerFactoryBean quartzScheduler = new SchedulerFactoryBean();

    quartzScheduler.setDataSource(dataSource);
    quartzScheduler.setTransactionManager(transactionManager);
    quartzScheduler.setOverwriteExistingJobs(true);
    quartzScheduler.setSchedulerName("mysuperduperthegratest-quartz-scheduler");

    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
    jobFactory.setApplicationContext(applicationContext);
    quartzScheduler.setJobFactory(jobFactory);
    quartzScheduler.setQuartzProperties(schedulingProperties);

    return quartzScheduler;
}

问题是最后的配置不起作用。这两个飞路豆都没有被创建过。我不明白为什么。回到我使用xml配置时,我记得在不同的配置文件中有两个具有相同名称的bean。它奏效了。我在这里做错了什么,或者这可能是Spring本身的一些错误?通常我自己调试Spring,但是使用@Configuration逻辑的Spring部分是一个绿色的文件,我现在不能浪费时间。

我知道这个问题很久以前就被问过了,但我在Spring Boot项目中遇到了一个使用Quartz和Flyway的问题。

Quartz会在flyway创建表之前尝试启动。以下对我有用:

@DependsOn("flywayInitializer")
public SchedulerFactoryBean quartzScheduler() { ...
