Neither BindingResult nor plain target object for bean name available as request attribute


Question

I'm just learning the ropes of Spring 3's annotation fu and I've stumbled upon the newb's nightmare exception. Would appreciate any help.

here's the form jsp code:

  <form:form method="POST" action="login.htm" modelAttribute="login">
  ....
  <form:input path="email" size="20" />
  ....

the controller code (at this point I'm simply testing the waters, so not directing to any page, just returning an empty string):

@Controller
@SessionAttributes
public class LoginController {

@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(    @ModelAttribute("login") Login login,
                        BindingResult result) {

    System.out.println(" email entered "+ login.getEmail()+ "\n");
    return "test";
}

"Login" is a form bean with the appropriate setter and getters.

i presume this bit of code in my dispatcher servlet should take care of the annotation scanning:

<context:component-scan
    base-package="com.testAnnFu.controller" />

and this is the shameful exception getting thrown when i try to load my landing jsp page.

I knocked off the form:input part and had a bare jsp page, that seems to load. only when i introduce the inputs are things going wrong.

i know there is something terribly wrong with my understanding of how this whole annotation thing gets wired up and maps to the ModelAttribute. I've rummaged through all combinations and posts in StOv for similar exceptions, but I've clearly missed something. could someone be so kind as to point out my blunder here?

Accepted Answer

In the controller, you need to add the login object as an attribute of the model:

model.addAttribute("login", new Login());

Like this:

@RequestMapping(value = "/", method = RequestMethod.GET) 
public String displayLogin(Model model) { 
    model.addAttribute("login", new Login()); 
    return "login"; 
}

You would have got this Exception while doing a GET on http://localhost:8080/projectname/login

As Vinay has correctly stated you can definitely use

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(Model model) { 
    model.addAttribute("login", new Login()); 
    return "login"; 
}

But I am going to provide some alternative syntax which I think you were trying with Spring 3.0.

You can also achieve the above functionality with

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(Login loginModel) { 
    return "login"; 
}

and it login.jsp (assuming you are using InternalResourceViewResolver) you can have

<form:form method="POST" action="login.htm" modelAttribute="login">

Notice : modelAttribute is login and not loginModel. It is as per the class name you provide in argument. But if you want to use loginModel as modelAttribute is jsp you can do the following

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(@ModelAttribute("loginModel")Login loginModel) { 
    return "login"; 
}

and jsp would have

<form:form method="POST" action="login.htm" modelAttribute="loginModel">

I know there are just different ways for doing the same thing. But the most important point to note here -

Imp Note: When you add your model class in your methods argument (like public String displayLogin(Login loginModel)) it is automatically created and added to your Model object (which is why you can directly access it in JSP without manually putting it in model). Then it will search your request if request has attributes that it can map with the new ModelObject create. If yes Spring will inject values from request parameters to your custom model object class (Login in this case).

You can test this by doing

@RequestMapping(value = "/login", method = RequestMethod.GET) 
public String displayLogin(Login loginModel, Model model) { 
    System.out.println(model.asMap().get("login").equals(loginModel));
    return "login"; 
}

Note : Above creating of new custom model object may not hold true if you have given @SessionAttributes({"login"}). In this case it will get from session and populate values.

I had problem like this, but with several "actions". My solution looks like this:

    <form method="POST" th:object="${searchRequest}" action="searchRequest" >
          <input type="text" th:field="*{name}"/>
          <input type="submit" value="find" th:value="find" />
    </form>
        ...
    <form method="POST" th:object="${commodity}" >
        <input type="text" th:field="*{description}"/>
        <input type="submit" value="add" />
    </form>

And controller

@Controller
@RequestMapping("/goods")
public class GoodsController {
    @RequestMapping(value = "add", method = GET)
    public String showGoodsForm(Model model){
           model.addAttribute(new Commodity());
           model.addAttribute("searchRequest", new SearchRequest());
           return "goodsForm";
    }
    @RequestMapping(value = "add", method = POST)
    public ModelAndView processAddCommodities(
            @Valid Commodity commodity,
            Errors errors) {
        if (errors.hasErrors()) {
            ModelAndView model = new ModelAndView("goodsForm");
            model.addObject("searchRequest", new SearchRequest());
            return model;
        }
        ModelAndView model = new ModelAndView("redirect:/goods/" + commodity.getName());
        model.addObject(new Commodity());
        model.addObject("searchRequest", new SearchRequest());
        return model;
    }
    @RequestMapping(value="searchRequest", method=POST)
    public String processFindCommodity(SearchRequest commodity, Model model) {
    ...
        return "catalog";
    }

I'm sure - here is not "best practice", but it is works without "Neither BindingResult nor plain target object for bean name available as request attribute".

the first time when you are returning your form make sure you pass the model attribute the form requires which can be done by adding the below code

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login(Login login)
    return "test";
}

By default the model attribute name is taken as Bean class's name with first lowercase letter

By doing this the form which expects a backing object naming "login" will be made available to it

after the form is submitted you can do the validation by passing your bean object and bindingresult as the method parameters as shown below

@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(    @ModelAttribute("login") Login login,
                        BindingResult result)

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

I had a similar problem in IntelliJ IDEA. My code was 100% correct, but after starting the Tomcat, you receive an exception. java.lang.IllegalStateException: Neither BindingResult

I just removed and added again Tomcat configuration. And it worked for me.
