redis和spring集成
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

<!-- 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);
