例如String数组转成Integer泛型的List
String [] pathArr = deptPath.split(",");
Lit<Integer> deptIds = Arrays.stream(pathArr).map(Integer::valueOf).collect(Collectors.toList());
如果是转成其他泛型的就改map里的Function,例如转成String类型的
String [] pathArr = deptPath.split(",");
Lit<String> deptIds = Arrays.stream(pathArr).map(String::valueOf).collect(Collectors.toList());
