Spring 带预定注释的缓存逐出

Spring cache eviction with scheduled annotation

在下面的代码中缓存有效,但驱逐无效,你能接近我吗? 我已阅读以下内容 link:

@Component
@RequiredArgsConstructor
public class CacheInvalidator {

    @Scheduled(fixedRate = 1000L)
    public void evictCache() {
       clearCache();
    }

    @CacheEvict(value = "count", allEntries = true)
    public void clearCache() {
    }
}

@Component
@RequiredArgsConstructor
public class ARepositoryImpl implements ARepository {

    @Cacheable(value = "count")
    public Integer count() {
        return jdbcTemplate.queryForObject("...", Integer.class);
    }
}

@SpringBootApplication
@EnableMongoRepositories
@EnableScheduling
@EnableCaching
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

在pom.xml中:

   <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>2.2.2.RELEASE</version>
       <relativePath/> <!-- lookup parent from repository -->
   </parent>

它不起作用,因为 CacheInvalidator 中的方法 evictCache 调用 clearCache 不是在 Spring 的代理上,而是在原始对象上,并且该方法尽管被注释但什么也不做@CacheEvict(value = "count", allEntries = true)

而不是:

@Component
@RequiredArgsConstructor
public class CacheInvalidator {

    @Scheduled(fixedRate = 1000L)
    public void evictCache() {
       clearCache();
    }

    @CacheEvict(value = "count", allEntries = true)
    public void clearCache() {
    }
}

尝试:

@Component
@RequiredArgsConstructor
public class CacheInvalidator {

    @Scheduled(fixedRate = 1000L)
    @CacheEvict(value = "count", allEntries = true)
    public void clearCache() {
    }

}
