Question

我想显示一个hashmap但是通过key和每个值一个td而不是一个整数？继承人的意思是：

                    String getDescription = rs.getString("description");
                    int level = rs.getInt("level");
                    Timestamp startDate = rs.getTimestamp("startDateTime");
                    Timestamp endDate = rs.getTimestamp("endDateTime");
                    String LessonId = rs.getString("lessonid");
                    this.less = new Lesson(getDescription, startDate, endDate, level, LessonId);

                    putDescriptions.add(less.description);
                    putStartTime.add(less.startTime);
                    endTime.add(less.endTime);
                    List list = Arrays.asList(less.date.split("2010"));
                    for (int i = 0; i < list.size(); i++) {
                        putDates.add(list.get(i).toString());
                        Level.add(less.level);
                        LessonID.add(less.ID);
                        this.lessons.put("description", putDescriptions);
                        this.lessons.put("StartDate", putDates);
                        this.lessons.put("StartTime", putStartTime);
                        this.lessons.put("EndTime", endTime);
                        this.lessons.put("Level", Level);
                        this.lessons.put("LessonID", LessonID);

//上面是bean代码

jstl：

      <c:forEach var="temp" items="${sessionScope.AvailableLessons['description']}">
                    <tbody>
                        <tr>
                            <form action="" method="POST">
                                <td>
                                    <c:out value="${temp}"/>

以下就足够了，

1。）循环应在外面，但在table tag内。

2。）在for each圈内，根据需要打开tr or td。

<c:forEach var="myVar" items="${myMap}">
    ${myVar.key} ${myVar.value}
</c:forEach>

我想用foreach逐个显示hashmap数据？
