2.1.4 SBA文档中的NotifierConfiguration示例

Question

我正尝试在我的Spring Boot Admin应用程序中实现存储库，但是代码片段given in documentation使用了一个没有在任何地方声明的“存储库”变量。如何获取这个变量？

Code Snippet

@Configuration
public class NotifierConfiguration {
    @Autowired
    private Notifier notifier;

    @Primary
    @Bean(initMethod = "start", destroyMethod = "stop")
    public RemindingNotifier remindingNotifier() {
        RemindingNotifier notifier = new RemindingNotifier(notifier, repository);
        notifier.setReminderPeriod(Duration.ofMinutes(10)); 
        notifier.setCheckReminderInverval(Duration.ofSeconds(10)); 
        return notifier;
    }
}

Answer 1

所以我能够通过使用SBA文档中的这个来解决这个问题。

    @Configuration
    public static class NotifierConfig {
        private final InstanceRepository repository;
        private final ObjectProvider<List<Notifier>> otherNotifiers;

        public NotifierConfig(InstanceRepository repository, ObjectProvider<List<Notifier>> otherNotifiers) {
            this.repository = repository;
            this.otherNotifiers = otherNotifiers;
        }

        @Bean
        public FilteringNotifier filteringNotifier() { 
            CompositeNotifier delegate = new CompositeNotifier(otherNotifiers.getIfAvailable(Collections::emptyList));
            return new FilteringNotifier(delegate, repository);
        }

        @Primary
        @Bean(initMethod = "start", destroyMethod = "stop")
        public RemindingNotifier remindingNotifier() { 
            RemindingNotifier notifier = new RemindingNotifier(filteringNotifier(), repository);
            notifier.setReminderPeriod(Duration.ofMinutes(10));
            notifier.setCheckReminderInverval(Duration.ofSeconds(10));
            return notifier;
        }
    }
