背景 - 基于给定的过滤条件(SearchCriteriaForm)填充的数据网格(ServiceOfferedForm列表)。此外,每个数据行都有一个绑定到ServiceOfferedForm的ID字段的radiobutton,它将填充在“selectedService”的serviceCode字段中,用于编辑操作。
我有一个如下的模型,有吸气剂和放大器setters(此处未显示) -
public class ServiceOfferedForm implements Serializable{
private String serviceCode;
private String serviceName;
private Boolean monday;
private Boolean tuesday;
private Boolean wednesday;
private Boolean thursday;
private Boolean friday;
private Boolean saturday;
private Boolean sunday;
在Controller类中 -
@RequestMapping(value="/services.html", method=RequestMethod.GET)
public String initManageServices(Model model){
ArrayList<ServiceOfferedForm> services = /*Code to fetch from database*/
model.addAttribute("servicesOffered",services);
//Adding other required attributes to model
model.addAttribute("searchCriteria",new SearchCriteriaForm());
model.addAttribute("selectedService",new ServiceOfferedForm());
return "services";
}
在我的services.jsp中,我有2个表单 - 一个用于Grid Filter&amp;另一个用于从网格编辑选定的行(将打开一个新屏幕进行编辑)
Form-1
<form:form id="filterUsersForm" method="post" action="services.html" modelAttribute="searchCriteria">
/*some code here */
<input type="submit"..>
</form:form>
表格-2
<form:form id="selectSvcFromGrid" method="get" action="editService" modelAttribute="selectedService" >
//Some code here for table header for grid
<c:forEach var="service" items="${servicesOffered}" varStatus="row">
<tr>
<td><form:checkbox path="servicesOffered[${row.index}].monday" disabled="true"/></td>
<td><form:checkbox path="servicesOffered[${row.index}].tuesday" disabled="true"/></td>
<td><form:checkbox path="servicesOffered[${row.index}].wednesday" disabled="true"/></td>
<td><form:checkbox path="servicesOffered[${row.index}].thursday" disabled="true"/></td>
<td><form:checkbox path="servicesOffered[${row.index}].friday" disabled="true"/></td>
<td><form:checkbox path="servicesOffered[${row.index}].saturday" disabled="true"/></td>
<td><form:checkbox path="servicesOffered[${row.index}].sunday" disabled="true"/></td>
</tr>
</c:forEach>
它提供org.springframework.beans.NotReadablePropertyException: Invalid property 'servicesOffered[0]' of bean class [com.tfts.form.ServiceOfferedForm]:
看起来它正在尝试在为Form-2(它是ServiceOfferedForm的实例)给出的modelAttribute“selectedService”中找到该属性。但这不是我想要的。 非常感谢有关如何解决此问题的建议!

<form:form>
希望能够使用单个&#34;命令&#34; object(由modelAttribute
属性指定),路径都是相对于此对象的。
创建一个简单的包装器对象以包含您的服务列表:
public class ServicesOfferedForm {
private List<ServiceOfferedForm> servicesOffered;
public ServicesOfferedForm(List<ServiceOfferedForm> servicesOffered) {
this.servicesOffered = servicesOffered;
}
public List<ServiceOfferedForm> getServicesOffered() {
return servicesOffered;
}
public void setServicesOffered(List<ServiceOfferedForm> servicesOffered) {
this.servicesOffered = servicesOffered;
}
}
然后将包装器添加到模型中:
model.addAttribute("selectedService", new ServicesOfferedForm(services));
您的JSP应该按预期工作而无需修改,但您也可以删除单独的servicesOffered
模型属性并将JSP循环更改为:
<c:forEach var="service" items="${selectedService.servicesOffered}" varStatus="row">
(请注意,问题首先不是forEach
- 如果您没有forEach
但尝试path="servicesOffered[0].monday"
则会遇到同样的问题)
