Spring Boot 2.x 集成Redis

Maven 配置

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-redis</artifactId>
		</dependency>

application.yml

spring:
  redis:
    host: 127.0.0.1
    port: 6379
    # 建议使用luttuce线程池，不建议使用jedis
    jedis:
      pool:
        max-active: 8
        max-wait: -1
        max-idle: 8
        min-idle: 0
    timeout: 10000

RedisConfig

@Configuration
@AutoConfigureAfter(RedisAutoConfiguration.class)
public class RedisConfig {
    
    

    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
    
    
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 使用Jackson2JsonRedisSerialize序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,ObjectMapper.DefaultTyping.NON_FINAL);

        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 设置key和value的序列化规则
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}

直接自动注入redisTemplate即可，无需其他配置

RedisUtils

@Component()
public class RedisUtils {
    
    
    @Autowired
    RedisTemplate redisTemplate;

    /**
     * redis set
     */
    public void setObject(String key,Object value){
    
    
        redisTemplate.opsForValue().set(key,value);
    }

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


}

搞定
