本文介绍了如何在SpringBoot项目中整合Redis集群，包括在pom.xml中添加依赖，配置application.properties，创建RedisConfig配置类，定义getJedisCluster方法，并在Controller中注入JedisCluster对象。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

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

pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

application.properties文件如下:

#springboot整合mybatis框架
#在pom.xml文件中加入整合mybatis的依赖
#加载mybatis的配置文件
mybatis.mapper-locations=classpath:mapper/*Mapper.xml

mybatis.type-aliases-package=com.example.demo.pojo

#数据源的配置
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.data-username=root
spring.datasource.data-password=123456

#整合Redis
#spring.redis.host=192.168.66.66
#spring.redis.port=6379

#整合Redis集群
spring.redis.cluster.nodes= 192.168.66.66:7001,192.168.66.66:7002,192.168.66.66:7002,192.168.66.66:7003,192.168.66.66:7004,192.168.66.66:7005,192.168.66.66:7006,192.168.66.66:7007,192.168.66.66:7008
