package com.uos.cache.config;

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;

@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory
                                                               redisConnectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);
        Jackson2JsonRedisSerializer jacksonSeial = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jacksonSeial.setObjectMapper(om);
        template.setDefaultSerializer(jacksonSeial);
        return template;
    }
}

二、效果测试

自定义RedisCacheManager

一、在RedisConfig上添加

@Bean
    public RedisCacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) {
        RedisSerializer<String> strSerializer = new StringRedisSerializer();
        Jackson2JsonRedisSerializer jacksonSeial = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jacksonSeial.setObjectMapper(om);
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(Duration.ofDays(1))
                .serializeKeysWith(RedisSerializationContext.SerializationPair
                        .fromSerializer(strSerializer))
                .serializeValuesWith(RedisSerializationContext.SerializationPair
                        .fromSerializer(jacksonSeial))
                .disableCachingNullValues();
        RedisCacheManager cacheManager = RedisCacheManager
                .builder(redisConnectionFactory).cacheDefaults(config).build();
        return cacheManager;
    }
