1、建一个redis.properties属性文件
# Redis Setting
redis.addr = 127.0.0.1
redis.port = 6379
redis.auth = master
redis.maxIdle = 200
redis.maxActive = 1024
redis.maxWait = 10000
redis.timeOut = 10000
redis.testOnBorrow = true
2、新建一个RedisUtil.java文件,文件代码如下:
package cn.com.taiji.sample.utils;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
import redis.clients.jedis.JedisShardInfo;
import redis.clients.jedis.ShardedJedis;
import redis.clients.jedis.ShardedJedisPool;
public class RedisUtil implements Serializable{
private static final long serialVersionUID = -1149678082569464779L;
//Redis服务器IP
private static String addr;
//Redis的端口号
private static int port;
//访问密码
private static String auth;
//可用连接实例的最大数目,默认值为8;
//如果赋值为-1,则表示不限制;如果pool已经分配了maxActive个jedis实例,则此时pool的状态为exhausted(耗尽)。
private static int maxActive;
//控制一个pool最多有多少个状态为idle(空闲的)的jedis实例,默认值也是8。
private static int maxIdle;
//等待可用连接的最大时间,单位毫秒,默认值为-1,表示永不超时。如果超过等待时间,则直接抛出JedisConnectionException;
private static int maxWait;
private static int timeOut;
//在borrow一个jedis实例时,是否提前进行validate操作;如果为true,则得到的jedis实例均是可用的;
private static boolean testOnBorrow;
public static Jedis jedis;//非切片额客户端连接
public static JedisPool jedisPool;//非切片连接池
public static ShardedJedis shardedJedis;//切片额客户端连接
public static ShardedJedisPool shardedJedisPool;//切片连接池
/**
* 初始化非切片池
*/
private static void initialPool()
{
// 池基本配置
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxTotal(maxActive);
config.setMaxIdle(maxIdle);
config.setMaxWaitMillis(maxWait);
config.setTestOnBorrow(testOnBorrow);
jedisPool = new JedisPool(config, addr, port);
}
/**
* 初始化切片池
*/
private static void initialShardedPool()
{
// 池基本配置
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxTotal(maxActive);
config.setMaxIdle(maxIdle);
config.setMaxWaitMillis(maxWait);
config.setTestOnBorrow(testOnBorrow);
// slave链接
List<JedisShardInfo> shards = new ArrayList<JedisShardInfo>();
shards.add(new JedisShardInfo(addr, port, auth));
// 构造池
shardedJedisPool = new ShardedJedisPool(config, shards);
}
public static void afterPropertiesSet() throws Exception {
// TODO Auto-generated method stub
initialPool();
initialShardedPool();
try {
shardedJedis = shardedJedisPool.getResource();
} catch (Exception e) {
System.out.println("连接shardedJedisPool失败!");
}
try {
jedis = jedisPool.getResource();
} catch (Exception e) {
System.out.println("连接jedisPool失败!");
}
}
public String getAddr() {
return addr;
}
public void setAddr(String addr) {
this.addr = addr;
}
public int getPort() {
return port;
}
public void setPort(int port) {
this.port = port;
}
public String getAuth() {
return auth;
}
public void setAuth(String auth) {
this.auth = auth;
}
public int getMaxActive() {
return maxActive;
}
public void setMaxActive(int maxActive) {
this.maxActive = maxActive;
}
public int getMaxIdle() {
return maxIdle;
}
public void setMaxIdle(int maxIdle) {
this.maxIdle = maxIdle;
}
public int getMaxWait() {
return maxWait;
}
public void setMaxWait(int maxWait) {
this.maxWait = maxWait;
}
public int getTimeOut() {
return timeOut;
}
public void setTimeOut(int timeOut) {
this.timeOut = timeOut;
}
public boolean isTestOnBorrow() {
return testOnBorrow;
}
public void setTestOnBorrow(boolean testOnBorrow) {
this.testOnBorrow = testOnBorrow;
}
}
在set方法中会飘黄,不影响使用。
3、在spring-servlet.xml配置文件中,加入以下代码:
<context:component-scan base-package="cn.com.taiji.sample.config.web" />
<context:property-placeholder location="file:#{systemProperties['webapp.sample']}/WEB-INF/conf/redis.properties" />
<bean id="redisUtil" class="cn.com.taiji.sample.utils.RedisUtil">
<property name="addr"><value>${redis.addr}</value></property>
<property name="port"><value>${redis.port}</value></property>
<property name="auth"><value>${redis.auth}</value></property>
<property name="maxIdle"><value>${redis.maxIdle}</value></property>
<property name="maxActive"><value>${redis.maxActive}</value></property>
<property name="maxWait"><value>${redis.maxWait}</value></property>
<property name="timeOut"><value>${redis.timeOut}</value></property>
<property name="testOnBorrow"><value>${redis.testOnBorrow}</value></property>
</bean>
<context:property-placeholder location="" />指的是redis.properties的文件路径。
到此,redis的spring配置就已经完成了。
