3, SpringBoot2.x integration redis combat explain

   Summary: springboot-starter integrated combat reids

       1, the official website: https: //docs.spring.io/spring-boot/docs/2.1.0.BUILD-SNAPSHOT/reference/htmlsingle/ # boot-features-redis
           cluster document: HTTPS: //docs.spring.io/spring-data/data-redis/docs/current/reference/html/#cluster

       2, springboot integration redis its dependencies introduced
           <dependency>
   <groupId > org.springframework.boot </ the groupId>
   <the artifactId> Starter-Spring-Boot-Data-Redis </ the artifactId>
   </ dependency>

   . 3, relevant profile configuration
           # ========= redis basic configuration = ========
           spring.redis.database = 0
           spring.redis.host = 127.0.0.1
           spring.redis.port=6390
           # Connection time units ms (milliseconds)
           spring.redis.timeout = 3000

           # ========= ========= provided Redis thread pool
           # connection pool maximum idle connection, the default value also 8.
           = 200 is IDLE-spring.redis.pool.max

           # minimum connection pool idle connections, the default value is 0.
           = 200 is IDLE-spring.redis.pool.min

           # If the assignment is -1, not to limit; maxActive pool have been allocated a jedis example, the pool state at this time is exhausted (exhausted).
           Active-2000 = spring.redis.pool.max

           # wait a maximum time available connections, in milliseconds, the default value is -1, never expires
           spring.redis.pool.max = the wait-1000

       . 4, and explanation of common type redistemplate cache practical operation (use automatic injector)

           1, injection template
           @Autowired
           Private StirngRedisTemplate strTplRedis

           2, the type of String, List, Hash, Set, ZSet
           a corresponding method are opsForValue (), opsForList (), opsForHash (), opsForSet (), opsForZSet ()

controller

RedisTemplate help us to operate Redis. opsForValue is a simple form of key value

there which a lot of ways

jsonData provides some return values of

Start the test

There is also no configuration redis profile. So used are default values

get from redis obtain key is the value of name
