RedisTemplate 配置类

Redistemplate在初始化时是无参构造，通过spring的bean加载机制在项目启动时执行afterPropertiesSet来完成序列化设置，如果需要自定义序列化配置，可以自己写一个Redistemplate的bean，来完成配置。

import com.fasterxml.jackson.annotation.JsonAutoDetect;
    import com.fasterxml.jackson.annotation.PropertyAccessor;
    import com.fasterxml.jackson.databind.ObjectMapper;
    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.serializer.Jackson2JsonRedisSerializer;
    import org.springframework.data.redis.serializer.StringRedisSerializer;
    
    /**
     * 配置redis序列化规则
     * key和value的序列化规则不尽相同
     *
     * @author XXLLXX
     * @date 2022
     */
    @Configuration
    public class RedisTemplateConfiguration {
    
        @Bean
        public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
            RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
            redisTemplate.setConnectionFactory(redisConnectionFactory);
            // 配置序列化规则
            Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
    
            ObjectMapper objectMapper = new ObjectMapper();
            objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
            jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
    
            // 设置key-value序列化规则
            redisTemplate.setKeySerializer(new StringRedisSerializer());
            redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
    
            // 设置hash-value序列化规则
            redisTemplate.setHashKeySerializer(new StringRedisSerializer());
            redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
    
            return redisTemplate;
    
        }
    
    }
