如何使用Redisson的布隆过滤器？

封装布隆过滤器

/*** 创建布隆过滤器** @param filterName - 过滤器名称* @param expectedInsertions - 预测插入数量* @param falsePositiveRate - 误判率* @author 付聪* @time 2024-09-20 17:24:10*/
<T> RBloomFilter<T> createBloomFilter(String filterName, Long expectedInsertions, Double falsePositiveRate);

@Override
public <T> RBloomFilter<T> createBloomFilter(String filterName, Long expectedInsertions, Double falsePositiveRate) {RBloomFilter<T> bloomFilter = redissonClient.getBloomFilter(filterName);bloomFilter.tryInit(expectedInsertions, falsePositiveRate);return bloomFilter;
}

使用示例

@Resource
private RedissonService redissonService;public void someMethod() {RBloomFilter<String> bloomFilter = redissonService.create("myBloomFilter", 10000, 0.03);bloomFilter.add("test");boolean result = bloomFilter.contains("test");System.out.println("Does 'test' exist? " + result);
}
