SpringBoot整合Redis集群-蒲公英云

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

pom.xml如下：
