servlet中list转换成一个歌的对象

el表达式只能取对象的值，不可以取list数组的值，所以在servlet方法中应该把list转换成具体的对象，然后再放到请求request中，这样el表达式才能读出具体值

List<Homework> homeworks = iws.queryHomeworksByTitle(title,cNumber,clNumber);Homework homework = homeworks.get(1);System.out.println(homeworks);request.setAttribute("homework", homework);request.setAttribute("homeworks", homeworks);
