Mybatis注解方式完成输入参数为list的SQL语句拼接方式

public String getDeptIdSql(List<Long> deptIdList){
    Iterator<Long> it = deptIdList.iterator();
    //当部门id为1时  不采用筛选
    while(it.hasNext()){
          Long deptId = it.next();
          if(deptId == 1){
                return "";
          }
    }
          //拼接in条件语句
          String s = "";
          for(int i = 0; i < deptIdList.size();i++){
                if(i!=(deptIdList.size()-1)){
