Spring BindingResult错误
我收到以下错误消息：
java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'billingInfoCommand' available as request attribute 我的JSP看起来像：
我的控制器看起来像：
public class BillingInfoController extends FusionFormController { protected final Log logger = LogFactory.getLog(getClass()); private FieldAccessService fieldAccessService; public BillingInfoController(){ setCommandClass(CommonCommand.class); setCommandName("billingInfoCommand"); } protected Map referenceData(HttpServletRequest request,Object command, Errors errors) throws Exception { CommonCommand commonCommand=(CommonCommand)command; HashMap refDataMap=new HashMap(); refDataMap.put("billingTypes",this.getLookupValsAsMap("getBillingTypes")); Long stageId=commonCommand.getEmeaMain().getStageId(); refDataMap.put("requiredFields",requiredFields); return refDataMap; } public Object formBackingObject(HttpServletRequest request){ BillingInfo billingInfoObj=null; Long cepWorkItemNo=null; CommonCommand billingInfoCommand=new CommonCommand(); try{ cepWorkItemNo=new Long(request.getParameter("cep_work_item_no")); }catch(NumberFormatException e){ } if(cepWorkItemNo==null){ billingInfoObj=new BillingInfo(); }else{ billingInfoObj=(BillingInfo)domainService.getDomainObject(BillingInfo.class,cepWorkItemNo); } if(billingInfoCommand.getBillingInfo()==null) billingInfoCommand.setBillingInfo(billingInfoObj); if(billingInfoCommand.getEmeaMain()==null) billingInfoCommand.setEmeaMain(emeaMain); return billingInfoCommand; } }
我的Pojo课程看起来像：
public class BillingInfo { private Integer billingId; public Integer getBillingId() { return billingId; } public void setBillingId(Integer billingId) { this.billingId = billingId; } }
注意
我这里只发布了相关的代码片段。 我不确定为什么我被提到有关IllegalStateException的错误，一些有用的指针将不胜感激。
此外，将Neither BindingResult nor plain target object for bean name x available as request attribute错误Neither BindingResult nor plain target object for bean name x available as request attribute正常原因是什么？
全栈跟踪

谢谢。
渲染jsp时会出现错误。 我假设你有一个可能有标签的jsp（spring：bind会导致同样的问题）
...
当它呈现jsp时，它会在您的请求范围中查找名为billingInfoCommand的bean，并使其可用于jstl表达式（以及其他内容）。 当请求范围中没有对象时，抛出您看到的exception。
编辑：
很高兴看到你没有从删除所有代码中得到任何错误。 接下来，请尝试直接查看请求范围。
The request scope is: ${requestScope} The command is: ${requestScope.billingInfoCommand}
如果你看到类似的东西
请求范围是：javax.servlet.jsp.el.ImplicitObjectELResolver ……
命令是：
那么你的bean实际上并不在请求范围内。 接下来要注意的是支持对象放在请求范围中的位置。 首先想到的是formBackingObject方法可能与将其放入请求有关。
这似乎是一个不正确的控制器/视图接线。 我这样说是因为我在堆栈跟踪中看不到对BilingInfoController的引用。 至少应该有一个对handleRequest / Internal的控制器的引用来加载formBackingObject。
确保使用的是在请求中设置绑定对象或Display对象
这应该在使用Binding Object之前或者在任何include jsp标签之前放置，如下所示
