spring-boot-starter-data-redis使⽤简介步骤
引⼊坐标
<!--redis-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<!-- jackson -->
<dependency>
<groupId>com.</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.1</version>
</dependency>
修改配置⽂件
spring:
#redis 连接信息
redis:
host: 127.0.0.1
port: 6379
password: password
timeout: 1000
注⼊RedisTemplate
/
**
* redis
*/
@Resource
private RedisTemplate redisTemplate;springboot结构
RedisTemplate使⽤
RedisTemplate中定义了对5种数据结构操作
redisTemplate.opsForValue();//操作字符串
redisTemplate.opsForHash();//操作hash
redisTemplate.opsForList();//操作list
redisTemplate.opsForSet();//操作set
redisTemplate.opsForZSet();//操作有序set
修改默认序列化⽅式
启动类上添加
/**
* 修改redis默认序列化
* @param redisConnectionFactory redis 连接
* @return redisTemplate
*/
@Bean
public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(redisConnectionFactory);
// 使⽤Jackson2JsonRedisSerialize 替换默认序列化
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
// 设置value的序列化规则和 key的序列化规则
redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.afterPropertiesSet();
return redisTemplate;
}
