springboot整合redis

Posted 2021-03-07 danger0us

1、引入依赖包

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

2、添加配置文件

spring:
  redis:
    database: 0
    host: 127.0.0.1
    port: 6379
    password: 123456

3、注入RedisTemplate，通过redisTemplate对redis进行操作

@Autowired
private RedisTemplate redisTemplate;

redisTemplate.opsForValue().set(key,value);

redisTemplate.opsForValue().get(key);

redisTemplate.delete(key);

4、使用RedisTemplate操作时，默认会采用jdkSerializable序列化机制，使得插入的值在redis客户端看来会有乱码，若想解决这一问题，需要手动指定序列化方式。

@Bean
public RedisTemplate<Object,Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
    RedisTemplate<Object,Object> redisTemplate = new RedisTemplate<>();
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    RedisSerializer serializer = new StringRedisSerializer();
    Jackson2JsonRedisSerializer jsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
    redisTemplate.setKeySerializer(serializer);
    redisTemplate.setValueSerializer(jsonRedisSerializer);
    return redisTemplate;
}
