求助:这种递归会不会造成打开的资源(conn,stmt,rs)不能关闭?

public static void deleteCategory(int id, int pid) {
    Connection conn = null;
    Statement stmtFindChild = null;
    Statement stmtDel = null;
    conn = DB.getConn();
    stmtFindChild = DB.getStmt(conn);
    stmtDel = DB.getStmt(conn);
    String sql = "delete from category where id = "+id;
    String sqlFindChild = "select * from category where pid = "+id;
    
    ResultSet rs = DB.getRs(stmtFindChild, sqlFindChild);
    try{
      while(rs.next()){
        deleteCategory(rs.getInt("id"),rs.getInt("pid"));
      }
      {
      DB.executeUpdate(stmtDel, sql);
      conn.close();
      stmtDel.close();
      stmtFindChild.close();
      rs.close();
      }
    }catch(SQLException e){
      e.printStackTrace();
    }finally{
      try{
        if(conn!=null){
        
        }
        if(stmtDel!=null){
          stmtDel.close();
        }
        if(stmtFindChild!=null){
          stmtFindChild.close();
        }
        if(rs!=null){
         rs.close();
        }    
      }catch(SQLException e){
        e.printStackTrace();
      }
    }
  }
