Spring-Boot-Data-Redis

RedisTemplate

RedisTemplate是Spring Data Redis提供的一个用于操作Redis的模板类。

它封装了对Redis的常见操作，如存储、读取、删除等，简化了与Redis交互的过程。

对接RedisTemplate命令参考如下。

import com.huawei.devspore.mas.redis.core.MultiZoneClient;
import com.huawei.devspore.mas.redis.spring.boot.cache.DcsConnectionFactory;
import org.springframework.boot.autoconfigure.condition.ConditionalOnSingleCandidate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;

@Configuration
public class TemplateConfig {
    @Bean
    public DcsConnectionFactory dcsConnectionFactory(MultiZoneClient client) {
        return new DcsConnectionFactory(client);
    }

    @Bean
    @ConditionalOnSingleCandidate(RedisConnectionFactory.class)
    public RedisTemplate<Object, Object> RedisTemplate(RedisConnectionFactory RedisConnectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(RedisConnectionFactory);
        return template;
    }

    @Bean
    @ConditionalOnSingleCandidate(RedisConnectionFactory.class)
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory RedisConnectionFactory) {
        return new StringRedisTemplate(RedisConnectionFactory);
    }

}

RedisCacheManager

RedisCacheManager是一个用于管理Redis缓存的工具类。

对接RedisCacheManager命令参考如下。

import com.huawei.devspore.mas.redis.core.MultiZoneClient;
import com.huawei.devspore.mas.redis.spring.boot.cache.DcsConnectionFactory;
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.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializationContext;
import org.springframework.data.redis.serializer.RedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import java.time.Duration;

@Configuration
public class TemplateConfig {
    @Bean
    public DcsConnectionFactory dcsConnectionFactory(MultiZoneClient client) {
        return new DcsConnectionFactory(client);
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory dcsConnectionFactory) {
        RedisSerializer<String> RedisSerializer = new StringRedisSerializer();
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();

        // 配置序列化
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofSeconds(5))   //设置缓存失效时间
                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(RedisSerializer))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer))
                .disableCachingNullValues();

        return RedisCacheManager.builder(dcsConnectionFactory)
                .cacheDefaults(config)
                .build();
    }

}
