Jedis连接池配置

摘要： 项目使用spring3.1版本，需要分环境（RND/Relesas/...）在Spring中配置Jedis连接池。此配置未使用Redis的分片。 

1.使用MAVEN引入使用的包。

2.Jedis的连接池配置需要用到org.apache.commons.pool.impl.GenericObjectPool.Config.class，此类是 GenericObjectPool的一个内部类，使用spring xml配置时需要转换成以下自定义类。

package com.antilost.redis.util;   import org.apache.commons.pool.impl.GenericObjectPool;   /**   * User: ***   * Date: 13-8-27   * Time: 下午3:49   */ public class GenericObjectPoolConfigWrapper {        private final GenericObjectPool.Config config;        public GenericObjectPoolConfigWrapper() {          this .config =  new GenericObjectPool.Config();      }        public GenericObjectPool.Config getConfig() {          return config;      }        public int getMaxIdle() {          return this .config.maxIdle;      }        public void setMaxIdle( int maxIdle) {          this .config.maxIdle = maxIdle;      }        public int getMinIdle() {          return this .config.minIdle;      }        public void setMinIdle( int minIdle) {          this .config.minIdle = minIdle;      }        public int getMaxActive() {          return this .config.maxActive;      }        public void setMaxActive( int maxActive) {          this .config.maxActive = maxActive;      }        public long getMaxWait() {          return this .config.maxWait;      }        public void setMaxWait( long maxWait) {          this .config.maxWait = maxWait;      }        public byte getWhenExhaustedAction() {          return this .config.whenExhaustedAction;      }        public void setWhenExhaustedAction( byte whenExhaustedAction) {          this .config.whenExhaustedAction = whenExhaustedAction;      }        public boolean isTestOnBorrow() {          return this .config.testOnBorrow;      }        public void setTestOnBorrow( boolean testOnBorrow) {          this .config.testOnBorrow = testOnBorrow;      }        public boolean isTestOnReturn() {          return this .config.testOnReturn;      }        public void setTestOnReturn( boolean testOnReturn) {          this .config.testOnReturn = testOnReturn;      }        public boolean isTestWhileIdle() {          return this .config.testWhileIdle;      }        public void setTestWhileIdle( boolean testWhileIdle) {          this .config.testWhileIdle = testWhileIdle;      }        public long getTimeBetweenEvictionRunsMillis() {          return this .config.timeBetweenEvictionRunsMillis;      }        public void setTimeBetweenEvictionRunsMillis(  long timeBetweenEvictionRunsMillis) {          this .config.timeBetweenEvictionRunsMillis = timeBetweenEvictionRunsMillis;      }        public int getNumTestsPerEvictionRun() {          return this .config.numTestsPerEvictionRun;      }        public void setNumTestsPerEvictionRun( int numTestsPerEvictionRun) {          this .config.numTestsPerEvictionRun = numTestsPerEvictionRun;      }        public long getMinEvictableIdleTimeMillis() {          return this .config.minEvictableIdleTimeMillis;      }        public void setMinEvictableIdleTimeMillis( long minEvictableIdleTimeMillis) {          this .config.minEvictableIdleTimeMillis = minEvictableIdleTimeMillis;      }        public long getSoftMinEvictableIdleTimeMillis() {          return this .config.softMinEvictableIdleTimeMillis;      }        public void setSoftMinEvictableIdleTimeMillis(  long softMinEvictableIdleTimeMillis) {          this .config.softMinEvictableIdleTimeMillis = softMinEvictableIdleTimeMillis;      }        public boolean isLifo() {          return this .config.lifo;      }        public void setLifo( boolean lifo) {          this .config.lifo = lifo;      } }

3.在Spring配置文件中注入GenericObjectPoolConfigWrapper.java类

< aop:aspectj-autoproxy /> < context:annotation-config /> < context:property-placeholder location = "classpath:jedis.properties" ignore-unresolvable = "true" /> < bean id = "jedisPoolConfig" class = "com.antilost.redis.util.GenericObjectPoolConfigWrapper" >          <!--最大连接数-->      < property name = "maxActive" value = "${${redis.pool.maxActive}}" />          <!--最大空闲连接数-->      < property name = "maxIdle" value = "${${redis.pool.maxIdle}}" />          <!--初始化连接数-->      < property name = "minIdle" value = "${${redis.pool.minIdle}}" />          <!--最大等待时间-->      < property name = "maxWait" value = "${${redis.pool.maxWait}}" />          <!--对拿到的connection进行validateObject校验-->      < property name = "testOnBorrow" value = "${redis.pool.testOnBorrow}" />          <!--在进行returnObject对返回的connection进行validateObject校验-->      < property name = "testOnReturn" value = "${redis.pool.testOnReturn}" />          <!--定时对线程池中空闲的链接进行validateObject校验-->          < property name = "testWhileIdle" value = "true" /> </ bean >

4.Redis的连接配置文件jedis.properties中，定义了各个环境的连接参数，具体配置如下

根据系统环境变量JVM中ServerType的值，取不同的配置，实现多环境（测试环境、生产环境）集成。
