Java无限级树(递归)超实用案例
如下所示：
@Override
publicStringgetEmployeeBysup(StringemployeeID){
Stringstr="";
str=getEmployeeBysupSelas(employeeID,str);
returnstr.substring(0,str.lastIndexOf(","));
}
@Override
publicStringgetEmployeeBysupSelas(StringemployeeID,Stringstr){
str+="'"+employeeID+"',";
System.out.println(str);
Stringsql="SELECTu.employeeIDfromtbl_system_useruwheresupervisorID='"+employeeID+"'";
List<String>list=jdbcTemplate.queryForList(sql,String.class);
if(list!=null&&list.size()>0){
for(inti=0;i<list.size();i++){
str=getEmployeeBysupSelas(list.get(i),str);
}
}
returnstr;
}
