springboot整合redisCluster集群（springboot整合redisCluster集群）

springboot整合redisCluster集群：（前提redis集群已經搭建好。windows上搭建redis集群參考：https://www.cnblogs.com/super-chao/p/9329018.html。linux上搭建redis集群步驟和windows上搭建redis集群一致）

1.引入springboot和redis的相關jar包：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.7.RELEASE</version>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <exclusions>
                <exclusion>
                    <artifactId>spring-aop</artifactId>
                    <groupId>org.springframework</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <exclusions>
                <exclusion>
                    <artifactId>spring-aop</artifactId>
                    <groupId>org.springframework</groupId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

2.創建application.yml配置文件並配置redis集群：

#server:
#  port: 8762
spring:
  application:
    name: redis
  #redis配置
  redis:
#    host: 192.168.1.100
#    port: 6385
    pool:
      max-idle: 100
      min-idle: 1
      max-active: 1000
      max-wait: -1
    database: 0
    timeout: 100000
    cluster:
      nodes:
        #地址要和redis配置中bind地址一致
        - 127.0.0.1:6379
        - 127.0.0.1:6380
        - 127.0.0.1:6381
        - 127.0.0.1:6382
        - 127.0.0.1:6383
        - 127.0.0.1:6384

3.redis工具類，RedisClusterService：

package com.springbootrediscluster.redis;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Service;

import java.util.concurrent.TimeUnit;

@Service
public class RedisClusterService {
    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    public void setStr(String key, String value) {
        setStr(key, value, null);
    }

    public void setStr(String key, String value, Long time) {
        /*stringRedisTemplate.opsForValue().set(key, value);
        if (time != null)
            stringRedisTemplate.expire(key, time, TimeUnit.SECONDS);*/
        stringRedisTemplate.opsForValue().set(key,value);
        if(time != null){
            stringRedisTemplate.expire(key, time, TimeUnit.SECONDS);
        }
        /*if(time != null){
            jedisCluster.expire(key,(int) (time/1000));
        }*/
    }

    public Object getKey(String key) {
        /*return redisTemplate.opsForValue().get(key);*/
        return stringRedisTemplate.opsForValue().get(key);
    }

    public void delKey(String key) {
        /*stringRedisTemplate.delete(key);*/
        stringRedisTemplate.delete(key);
    }
}

4.controller類，IndexController：

package com.springbootrediscluster.controller;

import com.springbootrediscluster.redis.RedisClusterService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * Created by Administrator on 2021/8/15.
 */
@Controller
public class IndexController {
    @Autowired
    private RedisClusterService redisClusterService;

    @RequestMapping("/setRedis")
    @ResponseBody
    public String setRedis(String key, String value) {
        redisClusterService.setStr(key, value);
        return "success";
    }

    @RequestMapping("/getKey")
    @ResponseBody
    public Object getKey(String key){
        Object result = redisClusterService.getKey(key);
        return result == null ? "緩存中沒有該數據" : result;
    }

    @RequestMapping("/delStringKey")
    @ResponseBody
    public String reStrRedis(String key){
        redisClusterService.delKey(key);
        return "success";
    }
}

5.springboot的app啟動類App：

package com.itmayiedu.app;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;

@ComponentScan("com.itmayiedu.**")
@EnableAutoConfiguration
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

 

6.測試：

 

 

 

 也可在dos命令窗口查看值，或者通過RedisClient可視化工具查看redis的值。

至此，springboot整合redisCluster集群完成。項目中可直接使用工具類RedisClusterService（可自行重構）對redisCluster集群操作。
