spring+redis 集群下的操作

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
