Redis是如今最火的缓存数据库之一，在springboot中经常有会使用到Redis，小伙伴们知道要如何在springboot中集成Redis吗?这次就一起来瞧瞧吧。
打开我们的springboot项目，直接配置：
pom.xml
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-cache</artifactId> </dependency> < dependency > <groupId>org.springframework.boot</groupId> < artifactId > spring - boot - starter - data - redis < /artifactId> < /dependency> application.yml
application.yml
spring: redis: database: 0 host: 192.168 .1 .102 port: 6379 cache: type: redis
redis
package com.fooww.research.housesourcelist.config;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheConfiguration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.cache.RedisCacheWriter;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.RedisSerializationContext;
import java.time.Duration;
/**

@Configuration
public class RedisConfig extends CachingConfigurerSupport
{
@Bean
public CacheManager cacheManager(RedisConnectionFactory factory)
{
//对象的序列化
RedisSerializationContext.SerializationPair valueSerializationPair = RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer());
//全局redis缓存过期时间
RedisCacheConfiguration redisCacheConfiguration = RedisCacheConfiguration.defaultCacheConfig()
.entryTtl(Duration.ofHours(1 L))
// .serializeKeysWith()
.serializeValuesWith(valueSerializationPair);
return new RedisCacheManager(RedisCacheWriter.nonLockingRedisCacheWriter(factory), redisCacheConfiguration);
}
private Jackson2JsonRedisSerializer < Object > jackson2JsonRedisSerializer()
{
Jackson2JsonRedisSerializer < Object > jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer < > (Object.class);
jackson2JsonRedisSerializer.setObjectMapper(objectMapper());
return jackson2JsonRedisSerializer;
}
private ObjectMapper objectMapper()
{
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
return objectMapper;
}
}启动类
@SpringBootApplication
@EnableCaching
public class HousesourcelistApplication
{
public static void main(String[] args)
{
SpringApplication.run(HousesourcelistApplication.class, args);
}
