String SQL = "SELECt * from note";
stmt = con.createStatement();
rs = stmt.executeQuery(SQL);
List mylist = new ArrayList();
while(rs.next()){
Book book = new Book();
book.setName(rs.getString(1));
book.setPasw(rs.getString(2));
mylist.add(book);
}
你要把mylist放在request里面
加上一句 request.setAttribut("mylist",mylist);
stmt = con.createStatement();
rs = stmt.executeQuery(SQL);
List
while(rs.next()){
Book book = new Book();
book.setName(rs.getString(1));
book.setPasw(rs.getString(2));
mylist.add(book);
}

后面掉了return mylist;
