最快的抽象速率限制器，基于 go-redis/redis。ratelimiter-go最快的抽象速率限制器，基于内存或 redis 存储。特征分布式原子性高性能支持redis集群支持记忆存储安装go get github.com/teambition/ratelimiter-goHTTP 服务器演示尝试进入github.com/teambition/ratelimiter-go目录go run example/main.go访问http://127.0.0.1:8080/package mainimport ( "fmt" "html" "log" "net/http" "strconv" "time" ratelimiter "github.com/teambition/ratelimiter-go" redis "github.com/go-redis/redis")// Implements RedisClient for redis.Clienttype redisClient struct {

这是一个 Java 语言的方法，接受一个字符串类型的参数 clientType，返回一个 Future<Long> 对象，表示异步计算结果。在方法中，使用 LambdaQueryWrapper 对象构建查询条件，并调用 baseMapper.selectCount 方法返回符合条件的记录数。如果 clientType 参数不为空，则在查询条件中添加对 clientType 字段的等值匹配。最后，将计算结果封装在 AsyncResult 中返回。
