1.添加依赖<!-- redis --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><!-- commons-pool2 --><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId></dependency>2.配置spring.redis.host=42.192.50.187
spring.redis.port=6379
spring.redis.password=redis@123
spring.redis.database=0
spring.redis.timeout=10000ms
# 连接池 - 最大连接数，默认：8
spring.redis.lettuce.pool.max-active=8
# 连接池 - 最大连接阻塞等待时间，默认：-1
spring.redis.lettuce.pool.max-wait=10000ms
# 连接池 - 最大、最小空闲连接数，最大默认：8，最小默认：0
spring.redis.lettuce.pool.max-idle=200
spring.redis.lettuce.pool.min-idle=53.配置类/*** 配置 RedisTemplate 序列化*/
@Configuration
public class RedisConfig {@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();// String 类型 - 序列化redisTemplate.setKeySerializer(new StringRedisSerializer());redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());// hash 类型 - 序列化redisTemplate.setHashKeySerializer(new StringRedisSerializer());redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());// 注入连接工厂redisTemplate.setConnectionFactory(redisConnectionFactory);return redisTemplate;}}4.使用# 注入依赖；@Autowiredprivate RedisTemplate redisTemplate;存储数据：redisTemplate.opsForValue().set("user:" + ticket, user);
