自定义RedisTemplate和RedisCacheManager

默认的RedisTemplate和RedisCacheManager的使用JDK的序列化方式，可以自定义为string和json序列化

@Configuration
public class MyRedisConfig {

@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory)
throws UnknownHostException {
// 为了开发方便，一般使用<String, Object>
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);

// Json序列化配置
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

// 设置key的序列化方式
template.setKeySerializer(stringRedisSerializer);

// 设置hashkey的序列化方式
template.setHashKeySerializer(stringRedisSerializer);

// 设置value的序列化方式
template.setValueSerializer(jackson2JsonRedisSerializer);

// 设置hashvalue的序列化方式
template.setHashValueSerializer(jackson2JsonRedisSerializer);

template.afterPropertiesSet();

return template;
}

@Bean
public RedisCacheManager myRedisCacheManager(RedisConnectionFactory redisConnectionFactory){
RedisSerializer<String> redisSerializer = new StringRedisSerializer();

Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);

// 配置序列化（解决乱码的问题）
RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer))
.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer))
.disableCachingNullValues();

RedisCacheManager cacheManager = RedisCacheManager.builder(redisConnectionFactory).cacheDefaults(config).build();

return cacheManager;
}

}
