一、java代码连接
1、新建工程,并引入以下包:
jedis-2.7.0.jar、commons-pool2-2.3.jar、junit-4.10.jar
2、单实例连接
/** * 单实例连接 */ @Test public void jedisClient(){ //创建一个Jedis的连接 Jedis jedis=new Jedis("192.168.7.151",6379); //可以选择库 jedis.select(2); //写入值 jedis.set("jediskey", "哈哈哈哈"); //获取值 String jedisStr=jedis.get("jediskey"); System.out.println(jedisStr); Assert.assertEquals("哈哈哈哈",jedisStr); //关闭连接 jedis.close(); }
2、连接池连接
/** * 连接池连接 */ @Test public void jedisPool(){ //创建一连接池对象 JedisPool pool=new JedisPool("192.168.7.151",6379); //从连接池中获得连接 Jedis jedis=pool.getResource(); jedis.select(3); jedis.set("jeds", "jedis连接池"); String getStr=jedis.get("jeds"); System.out.println(getStr); //关闭连接 jedis.close(); //关闭连接池 pool.close(); Assert.assertEquals("jedis连接池", getStr); }
3、JedisCluster连接集群
/** * JedisCluster 连接集群 * @throws Exception */ @Test public void testJedisCluster() throws Exception { //创建一连接,JedisCluster对象,在系统中是单例存在 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); //执行JedisCluster对象中的方法,方法和redis一一对应。 cluster.set("cluster-test", "my jedis cluster test"); String result = cluster.get("cluster-test"); System.out.println(result); //程序结束时需要关闭JedisCluster对象 cluster.close(); }
二、使用spring配置单机redis
1、新建工程,并引入以下包:
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目录:config,config里面添加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 "> <!-- 连接池配置 --> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <!-- 最大连接数 --> <property name="maxTotal" value="30" /> <!-- 最大空闲连接数 --> <property name="maxIdle" value="10" /> <!-- 每次释放连接的最大数目 --> <property name="numTestsPerEvictionRun" value="1024" /> <!-- 释放连接的扫描间隔(毫秒) --> <property name="timeBetweenEvictionRunsMillis" value="30000" /> <!-- 连接最小空闲时间 --> <property name="minEvictableIdleTimeMillis" value="1800000" /> <!-- 连接空闲多久后释放, 当空闲时间>该值 且 空闲连接>最大空闲连接数 时直接释放 --> <property name="softMinEvictableIdleTimeMillis" value="10000" /> <!-- 获取连接时的最大等待毫秒数,小于零:阻塞不确定的时间,默认-1 --> <property name="maxWaitMillis" value="1500" /> <!-- 在获取连接的时候检查有效性, 默认false --> <property name="testOnBorrow" value="false" /> <!-- 在空闲时检查有效性, 默认false --> <property name="testWhileIdle" value="true" /> <!-- 连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true --> <property name="blockWhenExhausted" value="false" /> </bean> <!-- redis单机 通过连接池 --> <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、测试方法如下:
/** * spring配置单机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测试redis"); String spring = jedis.get("spring"); System.out.println(spring); jedis.close(); pool.close(); applicationContext.close(); }
三、使用spring配置redis集群
1、工程与引入的包如上
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" 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 "> <!-- 连接池配置 --> <bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig"> <!-- 最大连接数 --> <property name="maxTotal" value="30" /> <!-- 最大空闲连接数 --> <property name="maxIdle" value="10" /> <!-- 每次释放连接的最大数目 --> <property name="numTestsPerEvictionRun" value="1024" /> <!-- 释放连接的扫描间隔(毫秒) --> <property name="timeBetweenEvictionRunsMillis" value="30000" /> <!-- 连接最小空闲时间 --> <property name="minEvictableIdleTimeMillis" value="1800000" /> <!-- 连接空闲多久后释放, 当空闲时间>该值 且 空闲连接>最大空闲连接数 时直接释放 --> <property name="softMinEvictableIdleTimeMillis" value="10000" /> <!-- 获取连接时的最大等待毫秒数,小于零:阻塞不确定的时间,默认-1 --> <property name="maxWaitMillis" value="1500" /> <!-- 在获取连接的时候检查有效性, 默认false --> <property name="testOnBorrow" value="false" /> <!-- 在空闲时检查有效性, 默认false --> <property name="testWhileIdle" value="true" /> <!-- 连接耗尽时是否阻塞, false报异常,ture阻塞直到超时, 默认true --> <property name="blockWhenExhausted" value="false" /> </bean> <!-- redis集群 --> <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> <constructor-arg index="1" value="7001"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg index="0" value="192.168.7.151"></constructor-arg> <constructor-arg index="1" value="7002"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg index="0" value="192.168.7.151"></constructor-arg> <constructor-arg index="1" value="7003"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg index="0" value="192.168.7.151"></constructor-arg> <constructor-arg index="1" value="7004"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg index="0" value="192.168.7.151"></constructor-arg> <constructor-arg index="1" value="7005"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg index="0" value="192.168.7.151"></constructor-arg> <constructor-arg index="1" value="7006"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg index="0" value="192.168.7.151"></constructor-arg> <constructor-arg index="1" value="7007"></constructor-arg> </bean> <bean class="redis.clients.jedis.HostAndPort"> <constructor-arg index="0" value="192.168.7.151"></constructor-arg> <constructor-arg index="1" value="7008"></constructor-arg> </bean> </set> </constructor-arg> <constructor-arg index="1" ref="jedisPoolConfig"></constructor-arg> </bean> </beans>
3、测试方法如下:
/** * spring配置redis集群 */ @Test public void getJedisPool(){ ClassPathXmlApplicationContext applicationContext=new ClassPathXmlApplicationContext("classpath:applicationContext2.xml"); JedisCluster jedisCluster = (JedisCluster) applicationContext.getBean("jedisCluster"); jedisCluster.set("jedisCluster","spring测试jedisCluster"); String spring = jedisCluster.get("jedisCluster"); System.out.println(spring); applicationContext.close(); }
