<!--springboot中的redis依賴--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>
配置
# Redis資料庫索引(預設為0) spring.redis.database=0 # Redis伺服器地址 spring.redis.host=39.96.162.54 # Redis伺服器連線埠 spring.redis.port=6379 # Redis伺服器連線密碼(預設為空) spring.redis.password=qweqwe # 連線超時時間(毫秒) spring.redis.timeout=0
配置類
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; /** * Redis的配置類 */ @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採用String的序列化方式 template.setKeySerializer(stringRedisSerializer); // hash的key也採用String的序列化方式 template.setHashKeySerializer(stringRedisSerializer); // value序列化方式採用jackson template.setValueSerializer(jackson2JsonRedisSerializer); // hash的value序列化方式採用jackson template.setHashValueSerializer(jackson2JsonRedisSerializer); template.afterPropertiesSet(); return template; } }
