Java 具有一对多映射的下拉列表（Spring/Hibernate）

现在我的数据库中有3张桌子——预订、餐厅和餐厅。我在餐厅和RestaurantTable之间有一个一对多映射（一个餐厅可以有许多桌子，但一个桌子只能有一个餐厅）。我有一个名为“editRestaurant.jsp”的文件，其中（除其他外）我希望在下拉列表中显示餐厅中当前的所有桌子。我想做一些与“newBooking.jsp”中类似的事情：

我当前的editRestaurant.jsp：

<div id="body">
<section class="content-wrapper main-content clear-fix">

    <h2>Edit</h2>

    <form:form modelAttribute="restaurant">
        <table>
            <tr>
                <td>Restaurant:</td>
                <td><form:input path="restaurantName" /></td>
                <td><form:errors path="restaurantName" cssClass="error"/></td>
            </tr>
            <tr>
                <td>Address:</td>
                <td><form:input path="address" /></td>
                <td><form:errors path="address" cssClass="error"/></td>
            </tr>
                <!--I want to put the list of tables here.-->
            <tr>
                <td colspan="3"><input type="submit" value="Submit" name="submit"/>
                </td>
            </tr>
        </table>
    </form:form>
    <div>
        <a href="/bookings">Back to List</a>
    </div>

感谢您的帮助

映射似乎是正确的。。。但问题是？？见：

@Entity
@Table(name="restaurant")
public class Restaurant {

    @Id
    @Column(name="id")
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    private Long id;

    @Column(name="restaurant_name")
    private String restaurantName;

    @Column(name="address")
    private String address;

    @OneToMany(mappedBy="restaurant", cascade = CascadeType.ALL)
    private Set<RestaurantTable> table;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getRestaurantName() {
        return restaurantName;
    }

    public void setRestaurantName(String restaurantName) {
        this.restaurantName = restaurantName;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public Set<RestaurantTable> getTable() {
        return table;
    }

    public void setTable(Set<RestaurantTable> table) {
        this.table = table;
    }

    public String toString() {
        return restaurantName;
    }
}

    public void setTableSize(int tableSize) {
        this.tableSize = tableSize;
    }

    public int getTableNumber() {
        return tableNumber;
    }

    public void setTableNumber(int tableNumber) {
        this.tableNumber = tableNumber;
    }

    public Restaurant getRestaurant() {
        return restaurant;
    }

    public void setRestaurant(Restaurant restaurant) {
        this.restaurant = restaurant;
    }

    public String toString() {
        return "Table number " + tableNumber;
    }

}
