扩展了redisson 2.x版本 添加可计数布隆过滤器

引入依赖包

<dependency>
  <groupId>com.github.slacrey</groupId>
  <artifactId>redisson-extend</artifactId>
  <version>1.1.2150</version>
</dependency>

创建Redisson连接

Config config = new Config();
        config.useSingleServer().setAddress("redis://127.0.0.1:6379");
        RedissonClientExtend redissonClientExtend = RedissonExtend.create(config);

创建过滤器

RCountingBloomFilter<String> bloomFilter = redissonClientExtend.getCountingBloomFilter("test2", 3);

getCountingBloomFilter(name, repeat)

• name 过滤器名称
• repeat 可重复次数

初始化过滤器

bloomFilter.tryInit(10000, 0.0001D);

boolean tryInit(long expectedInsertions, double falseProbability);

• expectedInsertions 容量
• falseProbability 错误率

使用方式

bloomFilter.add("test1");
bloomFilter.contains("test1")
bloomFilter.remove("test1")
