redisTemplate设置序列化方式.SpringCache设置序列化方式

在使用redisTemplate的时候,可以通过cachemanege来设置他的序列化方式,或者是使用springcache注解方式缓存时候的设置序列化方式

这里需要配置一个配置类

/**
 * spring-cache的缓存配置文件
 */
@Configuration
//开启缓存
@EnableCaching
public class RedisConfig2 {

    //配置redis的过期时间
    private Duration timeToLive = Duration.ZERO;

    public void setTimeToLive(Duration timeToLive) {
        this.timeToLive = timeToLive;
    }


    /**
     * 设置手动存的序列化方式
     *
     * @param redisConnectionFactory
     * @return
     */
    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setKeySerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    /**
     * 统一管理spting的cache
     *
     * @param factory redis的连接工厂
     * @return
     */
    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        //新建一个Jackson2JsonRedis的redis存储的序列化方式
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        //解决查询缓存转换异常的问题
        // 配置序列化（解决乱码的问题）
        //entryTtl设置过期时间
        //serializeValuesWith设置redis存储的序列化方式
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(timeToLive)
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer))
                .disableCachingNullValues();
        //定义要返回的redis缓存管理对象
        RedisCacheManager cacheManager = RedisCacheManager.builder(factory)
                .cacheDefaults(config)
                .build();
        return cacheManager;
    }
}

下面我将分开讲解

Redistemplate设置序列化方式

  @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();  //设置序列化方式,  这里我采用的是这个,当然序列化方式可以改为自己需要的
        //设置value的序列化方式
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer);
        //设置key的序列化方式
        redisTemplate.setKeySerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

设置cache的序列化方式

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory) {
        //新建一个Jackson2JsonRedis的redis存储的序列化方式
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();
        //解决查询缓存转换异常的问题
        // 配置序列化（解决乱码的问题）
        //entryTtl设置过期时间
        //serializeValuesWith设置redis存储的序列化方式
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(timeToLive)
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(genericJackson2JsonRedisSerializer))
                .disableCachingNullValues();
        //定义要返回的redis缓存管理对象
        RedisCacheManager cacheManager = RedisCacheManager.builder(factory)
                .cacheDefaults(config)
                .build();
        return cacheManager;
    }
