在java中操作redis_Data

 1.引入依赖

        <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency>

2.配置Redis数据源 

 

 

  redis:host: ${sky.redis.host}port: ${sky.redis.port}password: ${sky.redis.password}database: ${sky.redis.database}

 

  redis:host: localhostport: 6379password: 123456database: 0

3.编写配置 （Configuration）类RedisTemplate对象

@Configuration
@Slf4j
public class RedisConfiguration {@Beanpublic RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){log.info("开始创建redis模板类...");RedisTemplate redisTemplate = new RedisTemplate();// 设置Key的序列化器，默认为JdkSerializationRedisSerializerredisTemplate.setKeySerializer(new StringRedisSerializer());redisTemplate.setConnectionFactory(redisConnectionFactory);return redisTemplate;}}

 4.通过redisTemplate对象操作Redis

import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.connection.DataType;
