在spring中使用redis
java中操作redis使用的是jedis，首先在pom.xml中加入相关依赖：
<!-- redis cache related.....start --><dependency><groupid>org.springframework.data</groupid><artifactid>spring-data-redis</artifactid><version>1.6.0.release</version></dependency><dependency><groupid>redis.clients</groupid><artifactid>jedis</artifactid><version>2.7.3</version></dependency><!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 --><dependency> <groupid>org.apache.commons</groupid> <artifactid>commons-pool2</artifactid> <version>2.4.2</version></dependency><!-- redis cache related.....end -->
然后实现配置类：
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<string, string> redistemplate(redisconnectionfactory cf) {redistemplate<string, string> redistemplate = new redistemplate<string, string>();redistemplate.setconnectionfactory(cf);return redistemplate;}@beanpublic cachemanager cachemanager(redistemplate redistemplate) {rediscachemanager cachemanger = new rediscachemanager(redistemplate);cachemanger.setdefaultexpiration(5); //cache过期时间return cachemanger;}}
注意：
设置 cache 过期时间要合适，太长就长期有效，太短你看不到测试结果。建议 5-20秒。
最后直接在需要添加缓存的方法上使用注解就可实现缓存：
