基于Redis的Redisson框架之入门

入门：

　　1.依赖

   org.redisson
   redisson
   3.16.7
 

　　2.配置类

    @Bean
    public RedissonClient redissonClient(){
        Config config = new Config();
        config.useSingleServer().setAddress("redis://你的Redis地址");
        return Redisson.create(config);
    }

　　3.代码使用

@Autowired    
private RedissonClient redissonClient;

public void testlock3(){
    RLock lock = this.redissonClient.getLock("lock");
    lock.lock();
    try {
        String num = this.redisTemplate.opsForValue().get("num");
        if (StringUtils.isBlank(num)){
            this.redisTemplate.opsForValue().set("num","1");
            return;
        }
        int i = Integer.parseInt(num);//把字符串转化为数值
        this.redisTemplate.opsForValue().set("num",String.valueOf(++i));
    } finally {
        lock.unlock();
    }

}
