Docker Redis Introduction

// redis 이미지 불러오기
docker pull redis

// 불러온 이미지를 통해 redis docker 서버 실행
docker run --name myredis -d -p 6379:6379 redis

// redis 연결 확인
docker run -it --link myredis:redis --rm redis redis-cli -h redis -p 6379

// cmd에서 redis와 연결
docker run --network host -it --rm redis redis-cli -p 6379

//연결 후
set keyTest valueTest
get keyTest

Spring Boot Redis 설정

1. 파일 구조 / dependency

		<!-- pom.xml dependency 추가 -->
		<!-- Redis -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-redis</artifactId>
		</dependency>

application.yml 설정 추가

spring:
	redis:
        lettuce:
            pool:
                max-active: 10
                max-idle: 10
                min-idle: 2
        port: 6379
        host: 127.0.0.1
        password: 'abcde'

1. Config 설정

package com.web.curation.config;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory();
        return lettuceConnectionFactory;
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory());
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new StringRedisSerializer());
        return redisTemplate;
    }

    @Bean
    public StringRedisTemplate stringRedisTemplate() {
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setKeySerializer(new StringRedisSerializer());
        stringRedisTemplate.setValueSerializer(new StringRedisSerializer());
        stringRedisTemplate.setConnectionFactory(redisConnectionFactory());
        return stringRedisTemplate;
    }
}

1. RedisSampleService

package com.web.curation.Service;

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

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

    public void getRedisStringValue(String key) {

        ValueOperations<String, String> stringValueOperations = stringRedisTemplate.opsForValue();
        System.out.println("Redis key : " + key);
        System.out.println("Redis value : " + stringValueOperations.get(key));
    }
}

1. RedisSamplecontroller

package com.web.curation.controller.Redis;

import com.web.curation.Service.RedisSampleService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class RedisSampleController {

    @Autowired
    private RedisSampleService redisSampleService;

    @PostMapping(value = "/getRedisStringValue")
    public void getRedisStringValue(String key) {
        redisSampleService.getRedisStringValue(key);
    }
}

1. SpringBoot 실행 후 Postman으로 테스트
   1. get 테스트

   b. set 테스트

콘솔창에 정상 출력 확인 시

Redis를 이용한 캐시메모리 사용 가능
