1.引入依赖

org.springframework.boot
spring-boot-starter-data-redis

2.在yml文件中进行配置

3.redis相关配置类

package com.redis.confic;

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 {

  @Bean
  @SuppressWarnings("all")
  public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
      RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
      template.setConnectionFactory(factory);
      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);
      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;
  }


}

4.进行测试

@Test
    public void demo2() {
        User user = new User("zrq",18);
        Set<String> keys = redisTemplate.keys("*");
        redisTemplate.delete(keys);
        redisTemplate.opsForValue().set("user", JSON.toJSONString(user));
        String user1 = redisTemplate.opsForValue().get("user");
        System.out.println(user1);
        User user2 = JSON.parseObject(String.valueOf(user1), User.class);
        System.out.println(user2);

    }
