Playframework 如何在Play框架中的表单中设置int@Required？

我有一个类被传递到

form（）

：

---

当我在积分字段为空的情况下提交表格时，我会在表格错误中得到

错误。无效的
。如果我输入“0”，我会得到“Points min.=0”错误。当字段为空时，我应该如何获得“需要积分”消息？
我找到了答案。将字段类型
int
和
double
更改为
Integer
和
double

public static class Creation {
        @Required(message = "Checkpoint name is required")
        public String name;

        @Required(message = "Longitude degrees are required")
        public double longitudeDegrees;

        @Required(message = "Longitude minutes are required")
        public double longitudeMinutes;

        @Required(message = "Latitude degrees are required")
        public double latitudeDegrees;

        @Required(message = "Latitude minutes are required")
        public double latitudeMinutes;

        @Required(message = "Message is required")
        public String message;

        @Required(message = "Points are required")  
        @Min(value= 1, message = "Points min. = 0")
        public int points;
}
