java操作redis集群配置[可配置密码]和工具类

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
<version>2.4.2</version>
</dependency>

版本：jedis2.9.0[此版本可以加入密码配置]+commons-pools2.4.2

配置：

  <context:property-placeholder ignore-unresolvable="true" location="classpath*:cache.properties"/>

<bean id="jedisConfig" class="redis.clients.jedis.JedisPoolConfig">
<property name="maxTotal" value="150" />
<property name="maxIdle" value="50" />
<property name="minIdle" value="10" />
<property name="maxWaitMillis" value="3000" />

<property name="softMinEvictableIdleTimeMillis" value="10000" />
<property name="testOnBorrow" value="true" />
<property name="testWhileIdle" value="true" />
<property name="testOnReturn" value="true" />
<property name="blockWhenExhausted" value="false" />
</bean>
<bean id="hostport1" class="redis.clients.jedis.HostAndPort">
<constructor-arg name="host" value="${redis.host}"/>
<constructor-arg name="port" value="${redis.port1}"/>
</bean>
<bean id="hostport2" class="redis.clients.jedis.HostAndPort">
<constructor-arg name="host" value="${redis.host}"/>
<constructor-arg name="port" value="${redis.port2}"/>
</bean>
<bean id="hostport3" class="redis.clients.jedis.HostAndPort">

<constructor-arg name="port" value="${redis.port6}"/>
</bean>
<bean id="jedisCluster" class="redis.clients.jedis.JedisCluster">
<constructor-arg name="jedisClusterNode">
<set>
<ref bean="hostport1"/>
<ref bean="hostport2"/>

<constructor-arg name="poolConfig">
<ref bean="jedisConfig"/>
</constructor-arg>
</bean>
<bean id="jedisClientCluster" class="xx.xxx.xxxxx.xxxx.xxxx.JedisClientCluster"></bean>

创建cache.properties:

redis.host =192.168.xx.xxx

redis.port1=7001

redis.port2=7002

redis.port3=7003

redis.port4=7004

redis.port5=7005

redis.port6=7006

redis.clusterpassword=xxxxxxx

创建接口JedisClient:

import org.codehaus.jackson.type.TypeReference;
import java.util.List;
/**
* Created by gzy on 2017/11/17 17:16.
*/
public interface JedisClient {
String get(String key);
<T> T get(String key, TypeReference<T> clazz);
<T> T get(String key, Class<T> clazz);
String get(String key, int select);
void setAndExpire(String key, Object o, int expire);
Long rpush(String key, String string);
// Long del(String... keys);
Long lpush(String key, String string);
void set(String key, Object o);
String set(String key, String value);
String hget(String hkey, String key);
long hset(String hkey, String key, String value);
long incr(String key);
long expire(String key, int second);
long ttl(String key);
long del(String key);
long hdel(String hkey, String key);
Boolean exists(String key);
Long decr(String key);
List<String> brpop(int timeout, String key);
}

jedisClient实现类JedisClientCluster：

/**
* Created by gzy on 2017/11/17 17:17.
*/
import org.codehaus.jackson.type.TypeReference;
import com.thinkgem.jeesite.common.utils.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import redis.clients.jedis.JedisCluster;
import java.util.List;
public class JedisClientCluster implements JedisClient {
@Autowired
private JedisCluster jedisCluster;
public <T> T get(String key, TypeReference<T> clazz) {
String json = jedisCluster.get(key);
if (StringUtils.isNotEmpty(json)) {
return JsonUtil.Json2Object(json, clazz);
} else {
return null;
}
}
public <T> T get(String key, Class<T> clazz) {
String json = jedisCluster.get(key);
if (StringUtils.isNotEmpty(json)) {
return JsonUtil.Json2Object(json, clazz);
} else {
return null;
}
}
public void set(String key, Object o) {
String json = JsonUtil.Object2Json(o);
jedisCluster.set(key, json);
}
public void setAndExpire(String key, Object o, int expire) {
String json = JsonUtil.Object2Json(o);
jedisCluster.set(key, json);
jedisCluster.expire(key, expire);
}
// public long del(String key) {
// return jedisCluster.del(key);
// }
public String get(String key) {
return jedisCluster.get(key);
}
public String get(String key, int select) {
jedisCluster.select(select);
return jedisCluster.get(key);
}
@Override
public String set(String key, String value) {
return jedisCluster.set(key, value);
}
@Override
public String hget(String hkey, String key) {
return jedisCluster.hget(hkey, key);
}
@Override
public long hset(String hkey, String key, String value) {
return jedisCluster.hset(hkey, key, value);
}
@Override
public long incr(String key) {
return jedisCluster.incr(key);
}
public Long decr(String key) {
return jedisCluster.decr(key);
}
@Override
public long expire(String key, int second) {
return jedisCluster.expire(key, second);
}
@Override
public long ttl(String key) {
return jedisCluster.ttl(key);
}
@Override
public long del(String key) {
return jedisCluster.del(key);
}
@Override
public long hdel(String hkey, String key) {
return jedisCluster.hdel(hkey, key);
}
public Long rpush(String key, String string) {
return jedisCluster.rpush(key, string);
}
public Long lpush(String key, String string) {
return jedisCluster.lpush(key, string);
}
public Boolean exists(String key) {
return jedisCluster.exists(key);
}
public List<String> brpop(int timeout, String key) {
return jedisCluster.brpop(timeout, key);
}
}

创建测试类ClusterTest:

import xx.xx.xxx.xxxx.JedisClient;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
/**
* Created by gzy on 2017/11/20 15:22.
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:spring-context-cache.xml")
public class ClusterTest {
// private static JedisClientCluster redisCluster = SpringContextHolder.getBean("jedisClientCluster");
@Autowired
private JedisClient jedisClient;
@Test
public void testJCluster() {
jedisClient.set("test:phone:" + "11111111","hhha");
String result = jedisClient.get("test:phone:" + "11111111")
System.out.println("result==="+result)
}}

注意：Redis集群并不支持处理多个keys的命令,因为这需要在不同的节点间移动数据,从而达不到像Redis那样的性能,在高负载的情况下可能会导致不可预料的错误.
