1. 导入相关依赖

        <!--整合redis-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
            <version>2.3.0.RELEASE</version>
        </dependency>

2.配置redis服务端信息

spring.redis.host=x.x.x.x
spring.redis.port=6379
spring.redis.password=xxx

3.测试默认的RedisTemplate

4.自定义 RedisTemplate

package cn.hm1006.springbootstudy.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;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisConfig {

    /*自定义RedisTemplate*/
    @Bean
    @SuppressWarnings("all")
    public RedisTemplate<String,Object> redisTemplates(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<String,Object> template = new RedisTemplate<>();
         template.setConnectionFactory(redisConnectionFactory);

         //json序列化
        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) ;
        // string 的序列化
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        // key采用string的序列化方式
        template.setKeySerializer(stringRedisSerializer);
        // hash 的key也采用string的序列化方式
        template.setHashKeySerializer(stringRedisSerializer);
        // value序列化方式采用jackson
        template.setValueSerializer(jackson2JsonRedisSerializer);
        // hash 的value序列化方式采用jackson
        template.setHashValueSerializer(jackson2JsonRedisSerializer);
        template.afterPropertiesSet();
        return template;
    }
}
