redis'使用

1、配置文件

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-data-redis</artifactId>
  </dependency>
  
   <dependency>
      <groupId>redis.clients</groupId>
      <artifactId>jedis</artifactId>
      <version>3.2.0</version>
  </dependency>

2、配置文件

redis:
  database: 5
  host: localhost
  port: 6379
  password: password
  jedis:
    pool:
      max-active: 200
      max-wait: -1
      max-idle: 10
      min-idle: 0
    timeout: 6000

3、redis配置

public class RedisConfig {
  @Bean
  public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
    RedisTemplate<String, Object> template = new RedisTemplate<>();
    template.setConnectionFactory(factory);
    template.setKeySerializer(new StringRedisSerializer());
    template.setHashKeySerializer(new StringRedisSerializer());
    template.setValueSerializer(new GenericJackson2JsonRedisSerializer());
    template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
    template.afterPropertiesSet();
    return template;
  }
}

4、redis使用

@Autowired
private RedisTemplate redisTemplate;
  
     //从redis获取和设置值
      ValueOperations valueOperations = redisTemplate.opsForValue();
      Object redisOpenIdAcount = valueOperations.get("id");
       if (redisOpenIdAcount == null) {
      valueOperations.set(openid, 1);
      if (messageService.insertFeedMessage(feedMessage)) {
        logger.info("id不存在");
    } else {
      valueOperations.set("id", 2);
    }
