Hutool是一個(gè)Java工具包,提供了很多常用功能的封裝,包括Redis操作。要在集群環(huán)境下部署Hutool Redis,你需要遵循以下步驟:
pom.xml
文件中添加Hutool和Jedis依賴:<dependencies>
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>
<version>5.7.16</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>4.0.1</version>
</dependency>
</dependencies>
redis.conf
文件,配置多個(gè)Redis實(shí)例的地址。例如:# 節(jié)點(diǎn)1
port 7000
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 5000
# 節(jié)點(diǎn)2
port 7001
cluster-enabled yes
cluster-config-file nodes-7001.conf
cluster-node-timeout 5000
# 節(jié)點(diǎn)3
port 7002
cluster-enabled yes
cluster-config-file nodes-7002.conf
cluster-node-timeout 5000
redis-cli
工具啟動(dòng)集群:redis-cli --cluster create 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 --cluster-replicas 1
import cn.hutool.core.lang.Console;
import cn.hutool.core.net.url.UrlBuilder;
import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;
import java.util.HashSet;
import java.util.Set;
public class HutoolRedisCluster {
public static void main(String[] args) {
// 定義Redis集群節(jié)點(diǎn)
Set<HostAndPort> jedisClusterNodes = new HashSet<>();
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7000));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7001));
jedisClusterNodes.add(new HostAndPort("127.0.0.1", 7002));
// 創(chuàng)建Jedis集群實(shí)例
JedisCluster jedisCluster = new JedisCluster(jedisClusterNodes);
// 使用Hutool的UrlBuilder構(gòu)建Redis連接URL
UrlBuilder urlBuilder = UrlBuilder.create("redis://");
urlBuilder.setHost("127.0.0.1");
urlBuilder.setPort(7000);
urlBuilder.setParam("password", ""); // 如果設(shè)置了密碼,請(qǐng)取消注釋此行并填寫(xiě)密碼
// 使用Hutool的Jedis工具類操作Redis
jedisCluster.set("key", "value");
String value = jedisCluster.get("key");
Console.log("key: " + value);
// 關(guān)閉Jedis集群連接
jedisCluster.close();
}
}
現(xiàn)在你已經(jīng)成功使用Hutool在集群環(huán)境下部署了Redis。你可以根據(jù)需要修改代碼來(lái)實(shí)現(xiàn)更多的Redis操作。
