SpringBoot整合Redis集群

1.在pom.xml中加入redis的依赖
2.在application.properties加入整合redis的配置。（spring.redis.cluster.nodes=....）
3.新建一个RedisConfig.java文件，在此类的上面加入@Configuration注解，则此类相当于applicationContext.xml配置文件。
4.在RedisConfig类中写一个getJedisCluster方法，方法上加入@Bean注解，便可通过DI注入了。如下：package com.example.demo.config;

import java.util.HashSet;
import java.util.Set;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;

@Configuration//此注解相当于将此类变为applicationContext.xml,即配置文件
public class RedisConfig {
//注入集群节点信息：即application.properties中的spring.redis.cluster.nodes
@Value("${spring.redis.cluster.nodes}")
private String clusterNodes;

@Bean
public JedisCluster getJedisCluster(){
String cNodes[]=clusterNodes.split(",");
Set<HostAndPort> nodes=new HashSet<>();
for(String node:cNodes){
String hp[]=node.split(":");

nodes.add(new HostAndPort(hp[0], Integer.parseInt(hp[1])));

}

JedisCluster jedisCluster=new JedisCluster(nodes);
return jedisCluster;
}

}
5.在controller类里，注入JedisCluster集群对象
