RedisConfig 配置类

@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) {RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();// 设置Redis连接工厂redisTemplate.setConnectionFactory(connectionFactory);// 使用 GenericJackson2JsonRedisSerializer 来序列化和反序列化 redis 的 key 值，确保 key 是可读的字符串GenericJackson2JsonRedisSerializer jsonRedisSerializer = new GenericJackson2JsonRedisSerializer();redisTemplate.setKeySerializer(RedisSerializer.string());redisTemplate.setHashKeySerializer(RedisSerializer.string());redisTemplate.setValueSerializer(jsonRedisSerializer);redisTemplate.setHashValueSerializer(jsonRedisSerializer);return redisTemplate;}
}

@Builder
public class User {private Long id;private String userName;private String userSex;
}

`test` 测试

@SpringBootTest
public class RedisTest {@Resourceprivate RedisTemplate<String, Object> redisTemplate;@Testpublic void test1(){redisTemplate.opsForValue().set("redis_test:strKey", "haohao");System.out.println(redisTemplate.opsForValue().get("redis_test:strKey"));}@Testpublic void test2(){User user = User.builder().id(1L).userName("xiaoming").userSex("男").build();redisTemplate.opsForValue().set("redis_test:user", user);User user2 = (User) redisTemplate.opsForValue().get("redis_test:user");System.out.println("user:" + user2.getId() + "," + user2.getUserName() + "," + user2.getUserSex());}
}
