示例1: parseConnRestrictEntries
import com.taobao.tddl.atom.utils.ConnRestrictEntry; //導入方法依賴的package包/類
/**
* 解析應用連接限製, 完整格式是:
* "K1,K2,K3,K4:80%; K5,K6,K7,K8:80%; K9,K10,K11,K12:80%; *:16,80%; ~:80%;"
* 這樣可以兼容 HASH: "*:16,80%", 也可以兼容 LIST:
* "K1:80%; K2:80%; K3:80%; K4:80%; ~:80%;" 配置可以是連接數, 也可以是百分比。
