To refresh the Redis cache in a Spring Boot application, you can use the CacheManager
interface provided by Spring. This interface allows you to manage and manipulate caches programmatically, including refreshing cache entries.
Here's a guide on how to refresh Redis cache in Spring Boot:
@Bean
that returns a RedisCacheManager
instance.@Configuration
@EnableCaching
public class CacheConfiguration {
@Autowired
private RedisConnectionFactory redisConnectionFactory;
@Bean
public CacheManager cacheManager() {
RedisCacheConfiguration cacheConfiguration =
RedisCacheConfiguration.defaultCacheConfig()
.entryTtl(Duration.ofMinutes(10)); // Set time to live
return RedisCacheManager.builder(redisConnectionFactory)
.cacheDefaults(cacheConfiguration)
.transactionAware()
.build();
}
}
CacheManager
:
Inject the CacheManager
bean into your service or component class and use it to clear and reload cache entries.@Service
public class YourService {
@Autowired
private CacheManager cacheManager;
// A method to refresh your cache
public void refreshCache(String cacheName) {
Cache cache = cacheManager.getCache(cacheName);
if (cache != null) {
cache.clear(); // Clearing the cache
}
}
// Other methods and code for your service
}
refreshCache
method from your controller or another class to refresh the cache:@RestController
@RequestMapping("/api")
public class YourController {
@Autowired
private YourService yourService;
@PutMapping("/refresh-cache/{cacheName}")
public ResponseEntity<String> refreshCache(@PathVariable String cacheName) {
yourService.refreshCache(cacheName);
return ResponseEntity.ok("Cache " + cacheName + " has been refreshed.");
}
// Other methods and code for your controller
}
Now, you can call the /api/refresh-cache/{cacheName}
endpoint to refresh the specific Redis cache in your Spring Boot application.
