I'm trying to get Redisson set up to use for bucket4j with my spring boot 2.7.3 application running on JVM 17. For now, I'm using a unit test to get everything working at some reasonable level but obviously will need a for real implementation later.
On to the code...
@Configuration@EnableCachingpublic class Bucket4JConfig { public static final String CACHE_NAME = "r_quota_"; @Bean public Config envConfig() { var port = "6379"; var host = "localhost"; BinaryOperator<String> getUrl = (h, p) -> String.format("redis://%s:%s", h, p); Config config = new Config(); config.useReplicatedServers() .setReadMode(ReadMode.SLAVE) .addNodeAddress(getUrl.apply(host, port)); return config; } @Bean(name = "javaxCacheManager") public CacheManager cacheManager() { return Caching.getCachingProvider().getCacheManager(); } @Bean public ProxyManager<String> proxyManager(CacheManager cacheManager, Config config) { Cache<String, byte[]> cache = cacheManager.getCache(CACHE_NAME); if (cache == null) { MutableConfiguration<String, byte[]> jcacheConfig = new MutableConfiguration<>(); jcacheConfig.setExpiryPolicyFactory(null); // never expire javax.cache.configuration.Configuration<String, byte[]> redissonConfiguration = RedissonConfiguration.fromConfig(config, jcacheConfig); cache = cacheManager.createCache(CACHE_NAME, redissonConfiguration); } return new JCacheProxyManager<>(cache); } @Bean @Primary public SyncCacheResolver bucket4jCacheResolver(CacheManager cacheManager) { return new JCacheCacheResolver(cacheManager); } @Bean public JCacheManagerCustomizer jCacheManagerCustomizer(Config config) { return cacheManager -> cacheManager.createCache(CACHE_NAME, RedissonConfiguration.fromConfig(config)); }}@Servicepublic class RateLimitService { private static final int QUOTA = 2; private final ProxyManager<String> buckets; public RateLimitService(ProxyManager<String> buckets) { this.buckets = buckets; } public void blockOnBucket(String bucketName) throws InterruptedException { resolveBucket(bucketName).asBlocking().consume(1); } private Bucket resolveBucket(String bucketName) { Supplier<BucketConfiguration> confSupplier = () -> { return BucketConfiguration.builder() .addLimit(limit -> limit.capacity(QUOTA).refillGreedy(QUOTA, Duration.ofSeconds(1))) .build(); }; return buckets.builder().build(bucketName, confSupplier); }}public class Bucket4JOverRedissonTest { private RateLimitService rateLimitService; @BeforeEach public void setUp() { Bucket4JConfig conf = new Bucket4JConfig(); var config = conf.envConfig(); var cacheManager = conf.cacheManager(); System.out.printf("Caches: [%s]", Streams.stream(cacheManager.getCacheNames()).collect(Collectors.joining(","))); rateLimitService = new RateLimitService(conf.proxyManager(cacheManager, config)); } @Test public void test() throws InterruptedException { String bucketName = "LIMITED_RESOURCE"; StopWatch stopWatch = new StopWatch(); stopWatch.start();; rateLimitService.blockOnBucket(bucketName); rateLimitService.blockOnBucket(bucketName); rateLimitService.blockOnBucket(bucketName); stopWatch.stop(); Assertions.assertTrue(stopWatch.getTotalTimeMillis() > 1000); }}I added these lines to my pom.xml:
