这是我的代码片段:
车辆类:
// Duplicates
private Boolean regCard = true;
private Boolean decal;
private Boolean title;
public Boolean getRegCard() {
return regCard;
}
public void setRegCard(Boolean regCard) {
this.regCard = regCard;
}
public Boolean getDecal() {
return decal;
}
public void setDecal(Boolean decal) {
this.decal = decal;
}
public Boolean getTitle() {
return title;
}
public void setTitle(Boolean title) {
this.title = title;
}

问题:
布尔值永远不会在提交时设置。 我试过了另一种方式。使用List对象并将该变量绑定到具有正确th:value =“'SOMETEXT'”的复选框,用于每个复选框。但是该对象也保持为空。
如您所见,我事先将一个值设置为true,以查看它是否会显示在html端。它很成功。所以它至少要检索这个值,但是如果它发生变化就不会设置它。
另外,正如您所看到的,我尝试使用“th:value =”复选框“”查看是否有帮助。它没有。

我猜可能的解决方案是:
将复选框值作为请求参数传递
<label>Registration Card
<input type="checkbox" name="retCardChecked"/>
然后在控制器中捕获它并设置为Vehicle对象
@RequestParam("retCardChecked") boolean retCardChecked, ...

SIGH ......我找到了解决方案。
我很容易忽略了我所在的子流和视图状态的WebFlow xml def文件。
我有什么:
<view-state id="duplicate" view="duplicates">
<transition on="continue" to="checkVehicleInfo" />
<transition on="back" to="finished" />
</view-state>
视图状态中缺少的属性:
model="customerModel"
使用Spring WebFlow
时,表单提交需要这样做
