How to use redis in spring?
Using Redis in Spring
Jedis is used to manipulate Redis in Java. First, add related dependencies to pom.xml:
Org.springframework.dataspring-data-redis1.6.0.RELEASEredis.clientsjedis2.7.3 org.apache.commons commons-pool2 2.4.2
Then implement the configuration class:
Package com.ehelp.util; import org.springframework.cache.CacheManager;import org.springframework.cache.annotation.CachingConfigurerSupport;import org.springframework.cache.annotation.EnableCaching;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.data.redis.cache.RedisCacheManager;import org.springframework.data.redis.connection.RedisConnectionFactory;import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;import org.springframework.data.redis.core.RedisTemplate @ Configuration@EnableCachingpublic class RedisCacheConfig extends CachingConfigurerSupport {@ Beanpublic JedisConnectionFactory redisConnectionactory () {JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory (); redisConnectionFactory.setHostName ("localhost"); redisConnectionFactory.setPort (6379); return redisConnectionFactory;} @ Beanpublic RedisTemplate redisTemplate (RedisConnectionFactory cf) {RedisTemplate redisTemplate = new RedisTemplate (); redisTemplate.setConnectionFactory (cf); return redisTemplate;} @ Beanpublic CacheManager cacheManager (RedisTemplate redisTemplate) {RedisCacheManager cacheManger = new RedisCacheManager (redisTemplate); cacheManger.setDefaultExpiration (5); / / cache expiration time return cacheManger;}}
Note:
Set the Cache expiration time to be appropriate, if it is too long, it will be valid for a long time, and if it is too short, you will not see the test results. 5-20 seconds is recommended.
Finally, you can implement the cache by directly using annotations on the methods that need to be added:
