springBoot (springCloud2025)集成redisCluster 集群的操作方法_Java

在spring boot项目中集成redis cluster，你可以使用spring data redis库，它提供了对redis操作的抽象和封装。

cluster配置类

package com.emall.account_service.config;
import lombok.data;
import org.springframework.boot.context.properties.configurationproperties;
import java.util.arraylist;
import java.util.list;
@configurationproperties(prefix = "spring.redis.cluster")
@data
public class redisclusterproperties {
    private list<string> nodes = new arraylist<>();
    private integer maxredirects = 3;
    private string password;
}

其他配置类

package com.emall.account_service.config;
import lombok.data;
import org.springframework.boot.context.properties.configurationproperties;
import java.time.duration;
@configurationproperties(prefix = "spring.redis")
@data
public class rediscommonproperties {
    private duration timeout = duration.ofmillis(2000);
    private string password;
    private integer database = 0;
    private lettuce lettuce = new lettuce();
    @data
    public static class lettuce {
        private pool pool = new pool();
        private cluster cluster = new cluster();
        @data
        public static class pool {
            private int maxactive = 8;
            private int maxidle = 8;
            private int minidle = 0;
            private duration maxwait = duration.ofmillis(-1);
        }
        @data
        public static class cluster {
            private refresh refresh = new refresh();
            @data
            public static class refresh {
                private boolean adaptive = true;
                private duration period = duration.ofmillis(2000);
            }
        }
    }
}

连接池配置类

    private int minidle = 0;
    private duration maxwait = duration.ofmillis(-1);
    private duration timebetweenevictionruns = duration.ofmillis(30000);
}

    @autowired
    private redistemplate<string, object> redistemplate;
    /**
     * 设置缓存
     */
    public void set(string key, object value) {
        redistemplate.opsforvalue().set(key, value);
    }
    /**
     * 设置缓存并设置过期时间
     */
    public void set(string key, object value, long timeout, timeunit unit) {
        redistemplate.opsforvalue().set(key, value, timeout, unit);
    }
    /**
     * 获取缓存
     */
    public object get(string key) {
        return redistemplate.opsforvalue().get(key);
    }
    /**
     * 删除缓存
     */

    }
    /**
     * 设置过期时间
     */
    public boolean expire(string key, long timeout, timeunit unit) {
        return redistemplate.expire(key, timeout, unit);
    }
    /**
     * 判断key是否存在
     */
    public boolean haskey(string key) {
        return redistemplate.haskey(key);
    }
    /**
     * 哈希操作 - 设置字段值
     */
    public void hset(string key, string field, object value) {
        redistemplate.opsforhash().put(key, field, value);
    }
    /**
     * 哈希操作 - 获取字段值
     */
    public object hget(string key, string field) {
        return redistemplate.opsforhash().get(key, field);
    }
    /**
     * 列表操作 - 左推
     */
    public long lpush(string key, object value) {
        return redistemplate.opsforlist().leftpush(key, value);
    }
    /**
     * 列表操作 - 右弹出
     */
    public object rpop(string key) {
        return redistemplate.opsforlist().rightpop(key);
    }
}
