CacheManager Bean Jhipster

Question

我是Jhipster的新手并且昨天开始关注它。有一件事我不知道它现在是如何工作的，所以我希望我能在这里得到答案。

Jhipster创建一个UserService，它是用于管理用户的服务类。它依赖于在构造函数中自动装配的CacheManager。我的IDE抱怨CacheManager缺少Bean，但我认为是CacheConfuguration类中处理该依赖的Bean

@Configuration
@EnableCaching
@AutoConfigureAfter(value = { MetricsConfiguration.class })
@AutoConfigureBefore(value = { WebConfigurer.class, DatabaseConfiguration.class })
public class CacheConfiguration {

    private final javax.cache.configuration.Configuration<Object, Object> jcacheConfiguration;

    public CacheConfiguration(JHipsterProperties jHipsterProperties) {
        JHipsterProperties.Cache.Ehcache ehcache =
            jHipsterProperties.getCache().getEhcache();

        jcacheConfiguration = Eh107Configuration.fromEhcacheCacheConfiguration(
            CacheConfigurationBuilder.newCacheConfigurationBuilder(Object.class, Object.class,
                ResourcePoolsBuilder.heap(ehcache.getMaxEntries()))
                .withExpiry(Expirations.timeToLiveExpiration(Duration.of(ehcache.getTimeToLiveSeconds(), TimeUnit.SECONDS)))
                .build());
    }

    @Bean
    public JCacheManagerCustomizer cacheManagerCustomizer() {
        return cm -> {
            cm.createCache("users", jcacheConfiguration);
            cm.createCache(com.mycompany.myapp.domain.User.class.getName(), jcacheConfiguration);
            cm.createCache(com.mycompany.myapp.domain.Authority.class.getName(), jcacheConfiguration);
            cm.createCache(com.mycompany.myapp.domain.User.class.getName() + ".authorities", jcacheConfiguration);
            // jhipster-needle-ehcache-add-entry
        };
    }
}

有人可以解释CacheManager中的UserService是如何自动装配的。
