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      lt form form method  POST  action  login htm  modelAttribute  login  gt            lt form input path  email  size  20    gt           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    lt context component-scan     base-package  com testAnnFu controller    gt    and this is the shameful exception getting thrown when i try to load my landing jsp page    SEVERE  Neither BindingResult nor plain target object for bean name  login  available as

java 680    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

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

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

Just add     model addAttribute  login   new Login       to your method     it will work

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   lt form form method  POST  action  login htm  modelAttribute  login  gt    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   lt form form method  POST  action  login htm  modelAttribute  loginModel  gt    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 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   A picture Tomcat configuration

I had problem like this  but with several  actions   My solution looks like this        lt form method  POST  th object    searchRequest   action  searchRequest   gt             lt input type  text  th field    name    gt             lt input type  submit  value  find  th value  find    gt       lt  form gt                   lt form method  POST  th object    commodity    gt           lt input type  text  th field    description    gt           lt input type  submit  value  add    gt       lt  form gt    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
