redis和spring框架的整合
我这里创建的是maven工程,通过maven锁定版本号,管理jar包之间的依赖
1.在pom文件中,引入spring和redis的jar包的坐标:
<properties> <junit.version>4.12</junit.version> <spring.version>4.2.4.RELEASE</spring.version> <jedis.version>2.7.2</jedis.version> </properties> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> <!-- Redis客户端 --> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> </dependency>
2.将redis的基本数据类型操作封装成工具类
定义接口JedisClient:
package nyist.e3.utils.redis; public interface JedisClient { String set(String key, String value); String get(String key); Boolean exists(String key); Long expire(String key, int seconds); Long ttl(String key); Long incr(String key); Long hset(String key, String field, String value); String hget(String key, String field); Long hdel(String key, String... field); }
单机版实现该接口的操作:
package nyist.e3.utils.redis; import org.springframework.beans.factory.annotation.Autowired; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; public class JedisClientPool implements JedisClient { private JedisPool jedisPool; public JedisPool getJedisPool() { return jedisPool; } public void setJedisPool(JedisPool jedisPool) { this.jedisPool = jedisPool; } @Override public String set(String key, String value) { Jedis jedis = jedisPool.getResource(); String result = jedis.set(key, value); jedis.close(); return result; } @Override public String get(String key) { Jedis jedis = jedisPool.getResource(); String result = jedis.get(key); jedis.close(); return result; } @Override public Boolean exists(String key) { Jedis jedis = jedisPool.getResource(); Boolean result = jedis.exists(key); jedis.close(); return result; } @Override public Long expire(String key, int seconds) { Jedis jedis = jedisPool.getResource(); Long result = jedis.expire(key, seconds); jedis.close(); return result; } @Override public Long ttl(String key) { Jedis jedis = jedisPool.getResource(); Long result = jedis.ttl(key); jedis.close(); return result; } @Override public Long incr(String key) { Jedis jedis = jedisPool.getResource(); Long result = jedis.incr(key); jedis.close(); return result; } @Override public Long hset(String key, String field, String value) { Jedis jedis = jedisPool.getResource(); Long result = jedis.hset(key, field, value); jedis.close(); return result; } @Override public String hget(String key, String field) { Jedis jedis = jedisPool.getResource(); String result = jedis.hget(key, field); jedis.close(); return result; } @Override public Long hdel(String key, String... field) { Jedis jedis = jedisPool.getResource(); Long result = jedis.hdel(key, field); jedis.close(); return result; } }
集群实现该接口:
package nyist.e3.utils.redis; import redis.clients.jedis.JedisCluster; public class JedisClientCluster implements JedisClient { private JedisCluster jedisCluster; public JedisCluster getJedisCluster() { return jedisCluster; } public void setJedisCluster(JedisCluster jedisCluster) { this.jedisCluster = jedisCluster; } @Override public String set(String key, String value) { return jedisCluster.set(key, value); } @Override public String get(String key) { return jedisCluster.get(key); } @Override public Boolean exists(String key) { return jedisCluster.exists(key); } @Override public Long expire(String key, int seconds) { return jedisCluster.expire(key, seconds); } @Override public Long ttl(String key) { return jedisCluster.ttl(key); } @Override public Long incr(String key) { return jedisCluster.incr(key); } @Override public Long hset(String key, String field, String value) { return jedisCluster.hset(key, field, value); } @Override public String hget(String key, String field) { return jedisCluster.hget(key, field); } @Override public Long hdel(String key, String... field) { return jedisCluster.hdel(key, field); } }
3.在spring中配置单机版的连接池
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:dubbo="http://code.alibabatech.com/schema/dubbo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"> <!-- 将redis对象的创建交给spring容器完成 --> <!-- 注册单机版的redis,创建jedisPool,需要通过构造注入host和port --> <!-- 连接redis单机版 --> <!--注册单机版的实现类--> <bean id="jedisClientPool" class="nyist.e3.utils.redis.JedisClientPool"> <property name="jedisPool" ref="jedisPool"></property> </bean> <bean id="jedisPool" class="redis.clients.jedis.JedisPool"> <constructor-arg name="host" value="ip" /> <constructor-arg name="port" value="6379" /> </bean> </beans>
4.redis集群在spring中的配置
<bean id="jedisCluster" class="redis.clients.jedis.JedisCluster"> <!-- 通过构造注入节点列表,然后在列表中创建HostAndPort对象,通过构造注入host和port --> <constructor-arg> <set> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg name="host" value="ip"></constructor-arg> <constructor-arg name="port" value="xxxx1"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg name="host" value="ip"></constructor-arg> <constructor-arg name="port" value="xxxx2"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg name="host" value="ip"></constructor-arg> <constructor-arg name="port" value="xxxx3"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg name="host" value="ip"></constructor-arg> <constructor-arg name="port" value="xxxx4"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg name="host" value="ip"></constructor-arg> <constructor-arg name="port" value="xxxx5"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg name="host" value="ip"></constructor-arg> <constructor-arg name="port" value="xxxx6"></constructor-arg> </bean> </set> </constructor-arg> </bean> <!-- 配置redis集群的实现类 --> <bean id="jedisClientCluster" class="nyist.e3.utils.redis.JedisClientCluster"> <property name="jedisCluster" ref="jedisCluster"></property> </bean>
需要注意的是:单机版的配置和集群版的配置不能同时存在,如果使用集群版,将单机版的注释,使用单机版,注释集群版的配置。总之,只用配置一个。
6.话不多说,直接上测试的代码:
@Test public void testPool() { ApplicationContext context = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-redis.xml"); JedisClientPool jedisClientPool = (JedisClientPool) context.getBean("jedisClientPool"); jedisClientPool.set("school", "nyist"); String value = jedisClientPool.get("school"); System.out.println(value); }
