Xiaobian to share with you how to integrate the use of redis spring, I believe most people still do not know how to use, so share this article for your reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

1. brief introduction

Redis is based on C language development.

Redis is a key-value storage system. Similar to Memcached, it supports a relatively large number of stored value types, including string, list, set, zset, and hash.

redis is a cache database (one-sided understanding) can do both cache, you can also persist the data to disk!

2.pom.xml introduces related jars (errors have been reported due to jar version problems, please note)

org.apache.commons commons-pool2 2.2 org.springframework.data spring-data-redis 1.7.5.RELEASE redis.clients jedis 2.9.0

3.spring-redis.xml configuration file, configure key bean redisTemplate

The configuration file redis-config.properteis used above

redis.maxIdle=1redis.maxTotal=5redis.maxWaitMillis=30000redis.testOnBorrow=trueredis.hostname=127.0.0.1redis.port=6379

4. Redis has four key interfaces:

private ValueOperations valueOps;

private ListOperations listOps;

private SetOperations setOps;

private ZSetOperations zSetOps;

Data types corresponding to redis: string, hash, list, set, and zset(sorted set)

Specifically, use the following code:

//Add string ValueOperations value = this.redisTemplate.opsForValue();value.set ("hello", "hate");System.out.println (value.get("hello"));//add a hash set HashOperations hash =redisTemplate.opsForHash();hash.put ("Walmart,""fruit, ""apple");hash.put ("Walmart","Beverage", "Red Bull");System.out.println (hash.entries("Walmart"));//add a list set ListOperations list = redisTemplate.opsForList();list.rightPush ("course", "chinese");list.rightPush ("Course", "englise");System.out.println (list.range("lpList", 0, 1));//add a set SetOperations set = redisTemplate.opsForSet();set.add ("lpSet", "lp");set.add ("lpSet", "26");set.add ("lpSet", "178cm");//output set System.out.println (set.members("lpSet"));//add ordered set ZSetOperations zset = redisTemplate.opsForZSet();zset.add ("lpZset", "lp", 0);zset.add("lpZset", "26", 2);zset.add("lpZset", "178cm", 1);//Output ordered set set System.out.println(zset.rangeByScore("lpZset", 0, 2)); Above is "How spring integrates redis use" All the contents of this article, thank you for reading! I believe that everyone has a certain understanding, hope to share the content to help everyone, if you still want to learn more knowledge, welcome to pay attention to the industry information channel!
