我有一个像这样的模型对象:
class Model {
SubModel submodel = new SubModel();
}
class SubModel {
Map props = Maps.newHashmap();
}
并且在jsp中我想将它们绑定到像这样的输入:
<spring:bind path="submodel.props['key']">
....input...
....errors.....
</spring:bind>
我正在接受下一个例外:
Caused by: java.lang.IllegalArgumentException: Type must not be null
at org.springframework.util.Assert.notNull(Assert.java:112)
at org.springframework.core.convert.AbstractDescriptor.<init>(AbstractDescriptor.java:35)

at org.springframework.validation.AbstractPropertyBindingResult.findEditor(AbstractPropertyBindingResult.java:165)
at org.springframework.web.servlet.support.BindStatus.<init>(BindStatus.java:125)
是否可以将BindStatus与嵌套地图一起使用? BTW,jstl有效,但我想要一种更清晰的方法来绑定值和错误。
