[Redis] Gradle(그래들) 프로젝트 Redis(레디스) 설정 하기

안녕하세요. 오늘은 Spring Boot Gradle(그래들) 프로젝트에 Redis(레디스) 설정 및 테스트 하는 방법에 대해 알아보겠습니다.

 

1. build.gradle에 dependencies 부분에 아래 코드를 입력합니다.

	implementation 'org.springframework.boot:spring-boot-starter-data-redis'
	implementation 'org.springframework.session:spring-session-data-redis'
	implementation 'org.springframework.boot:spring-boot-starter-cache'

 

2. application.properties에 Redis(레디스) host와 port, password 설정 값을 셋팅합니다.

spring.session.store-type=redis
spring.redis.host=localhost
spring.redis.password=redis1234
spring.redis.port=6379

application.properties redis

 

 

3. Redis(레디스)를 테스트 할 컨트롤러를 만들어 줍니다.

저는 set, get을 할 수 있는 API를 만들어 주었습니다.

/getRedisKeyValue에는 ket를 받아 value를 리턴 하도록 하였습니다.

 

package com.gtit.api.controller;

import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.gtit.api.vo.TestReqVO;

import jakarta.servlet.http.HttpServletRequest;

@RestController
public class RedisTestController {

    private final RedisTemplate<String, String> redisTemplate;

    public RedisTestController(RedisTemplate<String, String> redisTemplate) {
        this.redisTemplate = redisTemplate;
    }
    
    @RequestMapping(value = "/setRedisKeyValue", method = RequestMethod.POST)
    public ResponseEntity<?> setRedisKeyValue(HttpServletRequest request) {
        ValueOperations<String, String> vop = redisTemplate.opsForValue();
        vop.set("name", "홍길동");
        vop.set("age", "19");
        vop.set("country", "korea");
        vop.set("gender", "man");
        return new ResponseEntity<>(HttpStatus.CREATED);
    }

    @RequestMapping(value = "/getRedisKeyValue", method = RequestMethod.GET)
    public ResponseEntity<?> getRedisKeyValue(TestReqVO req, HttpServletRequest request) {
        ValueOperations<String, String> vop = redisTemplate.opsForValue();
        String value = vop.get(req.getKey());
        return new ResponseEntity<>(value, HttpStatus.OK);
    }
}

4. RedisConfig를 만들어 줍니다.

 

package com.gtit.api.config;

import java.time.Duration;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cache.CacheManager;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.RedisSerializationContext;
import org.springframework.data.redis.serializer.StringRedisSerializer;
import org.springframework.session.data.redis.config.ConfigureRedisAction;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;

@Configuration
public class RedisConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.redis")
    public RedisConnectionFactory redisConnectionFactory() {
        return new 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 static ConfigureRedisAction configureRedisAction() {
        return ConfigureRedisAction.NO_OP;
    }
    
    @Bean
    public CacheManager cacheManager() {
       RedisCacheManager.RedisCacheManagerBuilder builder = RedisCacheManager.RedisCacheManagerBuilder.fromConnectionFactory(redisConnectionFactory()); 
       RedisCacheConfiguration configuration = RedisCacheConfiguration.defaultCacheConfig() 
    		   														  .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer())) // Value Serializer 변경
                                                                      .entryTtl(Duration.ofMinutes(5)); // 캐시 수명 5분       
      builder.cacheDefaults(configuration);
      return builder.build();
   }
}

5. postman으로 /setRedisKeyValue API를 호출하여 Redis(레디스)에 값을 셋팅해줍니다.

setRedisKeyValue

 

 

6. postman으로 /getRedisKeyValue API를 호출하여 age, name등을 호출하여 앞서 셋팅한 값을 리턴하는지 확인 합니다.

getRedisKeyValue age

getRedisKeyValue name
