java - 获取枚举类型的所有实例的列表并在 View 中迭代

Question

我有一个枚举如下:

    public static enum Status {
    UNKNOWN(0, "Unknown"), AVAILABLE(1, "Available"), ISSUED(2, "Issued"), RETURNED(
            3, "Returned"), DAMAGED(4, "Damaged"), LOST(5, "Lost"), UNDER_REPAIR(
            6, "Under Repair");

    private int id;
    private String description;

    public int getId() {
        return id;
    }

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

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    private Status(Integer id, String description) {
        this.id = id;
        this.description = description;
    }
}

如何获取所有枚举实例的列表并在 View 中迭代如下所示(我使用 angular js 在下面的代码中进行迭代):

            <select name="status" ng-model="ticket.status">
                <option value="">----Select----</option>
                    <option ng-repeat="s in statusList" value ={{s.id}}>{{s.description}}</option>
            </select>

Answer 1

可以访问所有可能的枚举值:

Status.values()

如果你想以角度访问这些值，你应该在 Java 中创建一个 Controller 并通过来自角度的 http 请求获取这些值。
