Spring Boot中集成Redis实现缓存功能

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializationContext;
import org.springframework.data.redis.core.RedisTemplate;
 
@SpringBootApplication
@EnableCaching
public class CacheApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(CacheApplication.class, args);
    }
 
    // 配置RedisTemplate
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(LettuceConnectionFactory connectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(connectionFactory);
        template.setKeySerializer(new GenericJackson2JsonRedisSerializer());
        template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        template.setHashKeySerializer(new GenericJackson2JsonRedisSerializer());
        template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        return template;
    }
}

这段代码演示了如何在Spring Boot应用程序中使用@EnableCaching注解启用缓存功能，并配置了一个RedisTemplate Bean来使用自定义的序列化方式。这样可以确保缓存数据在写入Redis和读取Redis时使用统一的序列化方式。
