一、java代碼連接
1、新建工程,並引入以下包:
jedis-2.7.0.jar、commons-pool2-2.3.jar、junit-4.10.jar
2、單實例連接
/**
* 單實例連接
*/
@Test
public void jedisClient(){
//創建一個Jedis的連接
Jedis jedis=new Jedis("192.168.7.151",6379);
//可以選擇庫
jedis.select(2);
//寫入值
jedis.set("jediskey", "哈哈哈哈");
//獲取值
String jedisStr=jedis.get("jediskey");
System.out.println(jedisStr);
Assert.assertEquals("哈哈哈哈",jedisStr);
//關閉連接
jedis.close();
}
2、連接池連接
/**
* 連接池連接
*/
@Test
public void jedisPool(){
//創建一連接池對象
JedisPool pool=new JedisPool("192.168.7.151",6379);
//從連接池中獲得連接
Jedis jedis=pool.getResource();
jedis.select(3);
jedis.set("jeds", "jedis連接池");
String getStr=jedis.get("jeds");
System.out.println(getStr);
//關閉連接
jedis.close();
//關閉連接池
pool.close();
Assert.assertEquals("jedis連接池", getStr);
}
3、JedisCluster連接集羣
/**
* JedisCluster 連接集羣
* @throws Exception
*/
@Test
public void testJedisCluster() throws Exception {
//創建一連接,JedisCluster對象,在系統中是單例存在
Set<HostAndPort> nodes = new HashSet<>();
nodes.add(new HostAndPort("192.168.7.151", 7001));
nodes.add(new HostAndPort("192.168.7.151", 7002));
nodes.add(new HostAndPort("192.168.7.151", 7003));
nodes.add(new HostAndPort("192.168.7.151", 7004));
nodes.add(new HostAndPort("192.168.7.151", 7005));
nodes.add(new HostAndPort("192.168.7.151", 7006));
nodes.add(new HostAndPort("192.168.7.151", 7007));
nodes.add(new HostAndPort("192.168.7.151", 7008));
JedisCluster cluster = new JedisCluster(nodes);
//執行JedisCluster對象中的方法,方法和redis一一對應。
cluster.set("cluster-test", "my jedis cluster test");
String result = cluster.get("cluster-test");
System.out.println(result);
//程序結束時需要關閉JedisCluster對象
cluster.close();
}
二、使用spring配置單機redis
1、新建工程,並引入以下包:
commons-pool2-2.3.jar
jedis-2.7.0.jar
junit-4.10.jar
spring-expression-3.2.0.RELEASE.jar
spring-core-3.2.0.RELEASE.jar
spring-context-3.2.0.RELEASE.jar
spring-beans-3.2.0.RELEASE.jar
commons-logging-1.1.1.jar
2、工程中新建Source Folder目錄:config,config裏面添加applicationContext.xml,如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd ">
<!-- 連接池配置 -->
<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
<!-- 最大連接數 -->
<property name="maxTotal" value="30" />
<!-- 最大空閒連接數 -->
<property name="maxIdle" value="10" />
<!-- 每次釋放連接的最大數目 -->
<property name="numTestsPerEvictionRun" value="1024" />
<!-- 釋放連接的掃描間隔(毫秒) -->
<property name="timeBetweenEvictionRunsMillis" value="30000" />
<!-- 連接最小空閒時間 -->
<property name="minEvictableIdleTimeMillis" value="1800000" />
<!-- 連接空閒多久後釋放, 當空閒時間>該值 且 空閒連接>最大空閒連接數 時直接釋放 -->
<property name="softMinEvictableIdleTimeMillis" value="10000" />
<!-- 獲取連接時的最大等待毫秒數,小於零:阻塞不確定的時間,默認-1 -->
<property name="maxWaitMillis" value="1500" />
<!-- 在獲取連接的時候檢查有效性, 默認false -->
<property name="testOnBorrow" value="false" />
<!-- 在空閒時檢查有效性, 默認false -->
<property name="testWhileIdle" value="true" />
<!-- 連接耗盡時是否阻塞, false報異常,ture阻塞直到超時, 默認true -->
<property name="blockWhenExhausted" value="false" />
</bean>
<!-- redis單機 通過連接池 -->
<bean id="jedisPool" class="redis.clients.jedis.JedisPool" destroy-method="close">
<constructor-arg name="poolConfig" ref="jedisPoolConfig" />
<constructor-arg name="host" value="192.168.7.151" />
<constructor-arg name="port" value="6379" />
</bean>
</beans>
3、測試方法如下:
/**
* spring配置單機redis
*/
@Test
public void getJedisPool(){
ClassPathXmlApplicationContext applicationContext=new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
JedisPool pool = (JedisPool) applicationContext.getBean("jedisPool");
Jedis jedis=pool.getResource();
jedis.set("spring","spring測試redis");
String spring = jedis.get("spring");
System.out.println(spring);
jedis.close();
pool.close();
applicationContext.close();
}
三、使用spring配置redis集羣
1、工程與引入的包如上
2、新建applicationContext2.xml如下:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/beans

<!-- 最大空閒連接數 -->

<!-- 每次釋放連接的最大數目 -->
<property name="numTestsPerEvictionRun" value="1024" />
<!-- 釋放連接的掃描間隔(毫秒) -->
<property name="timeBetweenEvictionRunsMillis" value="30000" />
<!-- 連接最小空閒時間 -->

<property name="testWhileIdle" value="true" />
<!-- 連接耗盡時是否阻塞, false報異常,ture阻塞直到超時, 默認true -->
<property name="blockWhenExhausted" value="false" />
</bean>
<!-- redis集羣 -->
<bean id="jedisCluster" class="redis.clients.jedis.JedisCluster">
<constructor-arg index="0">
<set>
<bean class="redis.clients.jedis.HostAndPort">
<constructor-arg index="0" value="192.168.7.151"></constructor-arg>

</bean>
</set>
</constructor-arg>
<constructor-arg index="1" ref="jedisPoolConfig"></constructor-arg>
</bean>
</beans>
3、測試方法如下:
/**
* spring配置redis集羣
*/
@Test
public void getJedisPool(){
ClassPathXmlApplicationContext applicationContext=new ClassPathXmlApplicationContext("classpath:applicationContext2.xml");
JedisCluster jedisCluster = (JedisCluster) applicationContext.getBean("jedisCluster");
jedisCluster.set("jedisCluster","spring測試jedisCluster");
String spring = jedisCluster.get("jedisCluster");
System.out.println(spring);
applicationContext.close();
}
