if redis.call("get",KEYS[1])==ARGV[1] then return redis.call("del",KEYS[1]) else return 0 end 1. 2. 3. 4. 5. 接下来,可以给 Lua 脚本求一个 SHA1 和,命令如下: redis-cli -a (这里填密码) -x script load < lua/releasewherevalueequal.
前者看hashCode()方法,后者看equal()方法。 接下来,一起来了解一下基本的数据类型和自定义类类型在计算hashCode和equal的区别。 代码: class VO { private String name; private String addr; public VO(String name, String addr) { = name; this.addr = addr; } @Override public String toString() { retu...

since: 1.0.0This command is equal to SINTER, but instead of returning the resulting set, it is stored in destination.该命令等于 SINTER,但是不返回结果集,而是存储在目标中。If destination already exists, it is overwritten.如果目的地已经存在,则覆盖它。1.6.2 返回结果集中的元素数 ...

json=jedis.get(key),判断是否获取值"empty".equal(json),如果相等,则抛出自定义异常,提示用户,或者直接返回 无效的。这样,当用户再次查询时,需要在 reids 缓存中查询,redis 会有对应的 Key 获取之前设置的 value 值,这样就不会再次调用数据库,影响效率等问题。
