文章就是记录一下工作当中的用到的点，与测试方法以备用，会不断更新。

配置文件spring-redis.xml：

属性文件redis.properties：自己redis的ip与端口

redis.host1=127.0.0.1
redis.port1=7001

redis.host2=127.0.0.1
redis.port2=7002

redis.host3=127.0.0.1
redis.port3=7003

redis.host4=127.0.0.1
redis.port4=7004

redis.host5=127.0.0.1
redis.port5=7005

redis.host6=127.0.0.1
redis.port6=7006

redis.minIdle=1
redis.maxIdle=300
redis.maxActive=600
redis.maxWait=10000
redis.testOnBorrow=true
spring.redis.cluster.max-redirects= 3

StringRedisTemplate （key与value的默认序列化是stringSerializer）继承自 RedisTemplate （JdkSerializationRedisSerializer默认的序列化机制）

操作具体

redis的string类型操作

  public static void testString(){
        ApplicationContext ac = new ClassPathXmlApplicationContext("spring-redis.xml");
        StringRedisTemplate template = (StringRedisTemplate) ac.getBean("stringRedisTemplate");
        ValueOperations<String, String> stringOpe = template.opsForValue();
        //插入   第三个参数为指定过期时间
        stringOpe.set("mingren","01");
        stringOpe.set("zuozhu","02",1);
        stringOpe.set("xiaoying","03",1, TimeUnit.MINUTES);
       //重新设置值追加
        stringOpe.append("mingren","hero");
        //获取值
        String mingren01 = stringOpe.get("mingren");
        System.out.println("mingren          ："+mingren01);
        //获取原来的值  并设置为新的值
        String mingrenGetAndSet = stringOpe.getAndSet("mingren", "01heros");
        System.out.println("mingrenGetAndSet          ："+mingrenGetAndSet);
        String mingren02 = stringOpe.get("mingren");
        System.out.println("mingren          ："+mingren02);
        //截取value值得一部分   0- -1  位全部
        String mingrenLL = stringOpe.get("mingren", 0, -1);
        System.out.println("mingrenLL          ："+mingrenLL);
        //bit的使用  bit 的位图  第5位设置为1  其他的位置为0
        Boolean bit = stringOpe.setBit("bit", 5, true);
        System.out.println("bit          ："+bit);
        Boolean bit1 = stringOpe.getBit("bit", 5);
       // BitSet java.util包下   位可以用来统计用户访问量  统计有多少位为1
        BitSet bitSet= BitSet.valueOf(stringOpe.get("bit").getBytes());
        System.out.println(" bitSet.cardinality()         ："+bitSet.cardinality());

        System.out.println("插入完成");

    }

redis实现队列
