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
@EnableCaching
public class RedisCacheConfig extends CachingConfigurerSupport {
  
@Bean
public JedisConnectionFactory redisConnectionactory() {
JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();
redisConnectionFactory.setHostName("localhost");
redisConnectionFactory.setPort(6379);
return redisConnectionFactory;
}
  
@Bean
public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf) {
RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();
redisTemplate.setConnectionFactory(cf);
return redisTemplate;
}
@Bean
public CacheManager cacheManager(RedisTemplate redisTemplate) {
RedisCacheManager cacheManger = new RedisCacheManager(redisTemplate);
cacheManger.setDefaultExpiration(5); //cache过期时间
return cacheManger;
}
}
