配置redis的序列化,注入RedisTemplate

public class RedisConfig  {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        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);
        template.setConnectionFactory(factory);
        //key序列化方式
        template.setKeySerializer(redisSerializer);
        //value序列化
        template.setValueSerializer(jackson2JsonRedisSerializer);
        //value hashmap序列化
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        return template;
    }

使用redis，必须配置redis序列化类

package com.example.config;
 
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.RedisSerializer;
 
@Configuration
public class RedisConfig {
    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
 
        // key   采用StringRedisSerializer
        // value 采用GenericJackson2JsonRedisSerializer
 
        RedisTemplate<String, Object> template = new RedisTemplate<>();
        // 关闭启用默认配置
        template.setEnableDefaultSerializer(false);
        // 连接工厂
        template.setConnectionFactory(factory);
        // key 序列化方式
        template.setKeySerializer(RedisSerializer.string());
        // value 序列化方式
        template.setValueSerializer(RedisSerializer.json());
        // hash key 序列化方式
        template.setHashKeySerializer(RedisSerializer.string());
        // hash value 序列化方式
        template.setHashValueSerializer(RedisSerializer.json());
        // 配置完成
        template.afterPropertiesSet();
        return template;
    }
 
}
