基于idea Maven中的redis配置使用详解

pom.xml文件需要的内容

<dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-redis</artifactId> <version>2.1.0.RELEASE</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <scope>test</scope> </dependency>

Spring配置文件需要的内容

<!-- spring data redis --> <bean class='org.springframework.data.redis.connection.jedis.JedisConnectionFactory'><property name='usePool' value='true'></property><property name='hostName' value='${redis.host}' /><property name='port' value='${redis.port}' /><!-- <property name='password' value=''/> --><property name='timeout' value='${redis.timeout}' /><property name='database' value='${redis.default.db}'></property><constructor-arg ref='jedisPoolConfig' /> </bean><!-- 连接池参数配置 --> <bean class='redis.clients.jedis.JedisPoolConfig'><property name='maxTotal' value='${redis.maxActive}' /><property name='maxIdle' value='${redis.maxIdle}' /><property name='maxWaitMillis' value='${redis.maxWait}' /> </bean> <!-- 配置redis模板,方便存取数据 --> <!-- <bean class='org.springframework.data.redis.core.StringRedisTemplate'>--> <bean class='org.springframework.data.redis.core.RedisTemplate'><property name='connectionFactory' ref='jedisConnectionFactory' /> </bean>

在resources中创建application.properties文件

jdbc.driver=com.mysql.jdbc.Driverjdbc.url=jdbc:mysql://127.0.0.1:3306/mybatis01?useUnicode=true&characterEncoding=UTF-8jdbc.username=rootjdbc.password=root #定义初始连接数jdbc.initialSize=0#定义最大连接数jdbc.maxActive=20#定义最大空闲jdbc.maxIdle=20#定义最小空闲jdbc.minIdle=1#定义最长等待时间jdbc.maxWait=60000 dbcp.initialSize=15dbcp.maxActive=5000dbcp.maxIdle=0dbcp.maxWait=900000dbcp.defaultAutoCommit=truedbcp.removeAbandoned=truedbcp.removeAbandonedTimeout=30dbcp.whenExhaustedAction=1dbcp.validationQuery=select 1dbcp.testOnBorrow=fasledbcp.testOnReturn=false #redis的服务器地址redis.host=127.0.0.1#redis的服务端口redis.port=6379#密码redis.pass=root#链接数据库redis.default.db=0#客户端超时时间单位是毫秒redis.timeout=100000#最大连接数redis.maxActive=300#最大空闲数redis.maxIdle=100#最大建立连接等待时间redis.maxWait=1000#指明是否在从池中取出连接前进行检验,如果检验失败,则从池中去除连接并尝试取出另一个#DBSync.testOnBorrow=trueredis.clientName=requirepass

redis几种类型的测试(String、list、hash、set、sortedset)

package cn.hp; import org.junit.Test;import redis.clients.jedis.Jedis;import redis.clients.jedis.JedisPool;import redis.clients.jedis.JedisPoolConfig; import java.util.List;import java.util.Map;import java.util.Set;import java.util.stream.Stream; public class JedisTest { @Test public void test1(){Jedis jedis = new Jedis('127.0.0.1',6379);jedis.select(1);jedis.set('username','张三');System.out.println(jedis.get('username'));jedis.close(); } /** * 存储以时间为限定的数据 */ @Test public void test2(){Jedis jedis = new Jedis('127.0.0.1',6379);jedis.select(1);jedis.setex('code',20,'778899');System.out.println(jedis.get('code'));jedis.close(); } /** * */ @Test public void test3(){Jedis jedis = new Jedis('127.0.0.1',6379);jedis.lpush('mylist','b','c','d');jedis.rpush('mylist','e','f','g');List<String> jlist = jedis.lrange('mylist',0,-1);for (String j:jlist){ System.out.println(j);}jedis.close(); } /** * 操作set集合 */ @Test public void test4(){Jedis jedis = new Jedis('127.0.0.1',6379);jedis.sadd('myset','zs','ls','ww','zl');Set<String> set=jedis.smembers('myset');for (String s:set){ System.out.println(s);}jedis.close(); } /** * 操作hash 哈希类型 */ @Test public void test5(){Jedis jedis = new Jedis('127.0.0.1',6379);jedis.hset('myhash','userName','zs');jedis.hset('myhash','pass','123456');Map<String ,String>map = jedis.hgetAll('myhash');Set<String> keys = map.keySet();for (String k:keys){ String value = map.get(k); System.out.println('k'+k+'value:'+value);}jedis.close(); } /** * 排序 */ @Test public void test6(){Jedis jedis = new Jedis('127.0.0.1',6379);jedis.zadd('mysort',90,'zs');jedis.zadd('mysort',80,'ls');jedis.zadd('mysort',70,'ww');Set<String> set=jedis.zrange('mysort',0,-1);for (String s:set){ System.out.println(s);}jedis.close(); } /** * jedis 连接池使用 */ @Test public void test7(){JedisPoolConfig config=new JedisPoolConfig();//创建一个配置对象config.setMaxTotal(50);config.setMaxIdle(10);JedisPool jedisPool = new JedisPool(config, '127.0.0.1', 6379);//获取连接池//从连接池拿到一个jedis连接Jedis jedis = jedisPool.getResource();jedis.set('aabb','123');jedis.close();//归还连接 } }
