Neither Bindingresult nor plain target object for bean

When you develop a project, if you choose the Spring MVC Framework, and you use the spring label in the foreground, then you are likely to appear in this situation.

Javax.servlet.jsp.JspTagException:Neither Bindingresult nor plain target object for Bean name ' command ' available as requ EST attribute

Method: 1 Throws an exception cause, 2 is the exception workaround.

1. Reason: Enter the spring:bind tag source code you can see

Object target = Requestcontext.getmodelobject (beanname);
if (target = = null) {
throw new IllegalStateException ("Neither Bindingresult nor plain target object for Bean name '" +
Beanname + "' Available as request attribute");
}

Beanname= <spring:bind path= "COMMAND.SPJG" > Green section

If you are making a request directly to a page, the object is not command in request

2.

On the page, add

<jsp:usebean id= "command" class= "Com.ztenc.proj.bean.AFRFOAP" scope= "Request" ></jsp:useBean>

The red part fills in your binding class

PS: Although unknown, but feel Li ~

The above content is reproduced, followed by my own original solution:

At the controller place. Plus:

@ModelAttribute
Public Product Get (@RequestParam (required=false) Long ID) {
return id==null?new Product ():p roductservice.findone (ID);
}

Everything OK

Neither Bindingresult nor plain target object for bean
