Neither BindingResult nor the regular target for the bean name, available as an attr request

Question

---

Hi experts, I have this controller code that throws the above error. It worked until yesterday, I do not know what a colleague on this code did, and today I see an error:

Neither the BindingResult nor the regular target for the bean name 'sideForm', available as a request attribute

Could you suggest me where to look for such an error. Can I make a mistake in declaring a POST or GET method or returning something wrong?

Your help is much appreciated :)

This page gets the values ​​from the form shown below:

Answer 1

Make sure that Spring says modelAttribute="<Model Name" .

Example:

 @Controller @RequestMapping("/greeting.html") public class GreetingController { @ModelAttribute("greeting") public Greeting getGreetingObject() { return new Greeting(); } /** * GET * * */ @RequestMapping(method = RequestMethod.GET) public String handleRequest() { return "greeting"; } /** * POST * * */ @RequestMapping(method = RequestMethod.POST) public ModelAndView processSubmit(@ModelAttribute("greeting") Greeting greeting, BindingResult result){ ModelAndView mv = new ModelAndView(); mv.addObject("greeting", greeting); return mv; } } 

In your JSP:

 <form:form modelAttribute="greeting" method="POST" action="greeting.html"> 

Answer 2

Make sure you declare a bean associated with the form in the GET method of the associated controller, and also add it to the model.addAttribute("uploadItem", uploadItem); model model.addAttribute("uploadItem", uploadItem); which contains the annotation @RequestMapping(method = RequestMethod.GET) .

For example, UploadItem.java is associated with myform.jsp, and the controller is SecureAreaController.java

myform.jsp contains

 <form:form action="/securedArea" commandName="uploadItem" enctype="multipart/form-data"></form:form> 

MyFormController.java

 @RequestMapping("/securedArea") @Controller public class SecureAreaController { @RequestMapping(method = RequestMethod.GET) public String showForm(Model model) { UploadItem uploadItem = new UploadItem(); // declareing model.addAttribute("uploadItem", uploadItem); // adding in model return "securedArea/upload"; } } 

As you can see, I declare UploadItem.java in the controller's GET method.

Answer 3

Try adding the BindingResult parameter to methods annotated with @RequestMapping , which have annotated @ModelAttribute parameters. After each parameter, @ModelAttribute Spring looks for BindingResult in the next parameter position (order is important).

So try changing:

 @RequestMapping(method = RequestMethod.POST) public String loadCharts(HttpServletRequest request, ModelMap model, @ModelAttribute("sideForm") Chart chart) ... 

To:

 @RequestMapping(method = RequestMethod.POST) public String loadCharts(@ModelAttribute("sideForm") Chart chart, BindingResult bindingResult, HttpServletRequest request, ModelMap model) ... 

Answer 4

I worked on the same problem, and I'm sure I found out what exactly is the reason.

Neither the BindingResult nor the regular target for the bean name 'command', available as a request attribute

If the value of the successView property (jsp page name) matches the name of your input page, then the second value of the ModelAndView constructor must match the name of the command on the input page.

eg.

index.jsp

 <html> <body> <table> <tr><td><a href="Login.html">Login</a></td></tr> </table> </body> </html> 

dispatcher-servlet.xml

 <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix"> <value>/WEB-INF/jsp/</value> </property> <property name="suffix"> <value>.jsp</value> </property> </bean> <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="urlMap"> <map> <entry key="/Login.html"> <ref bean="userController"/> </entry> </map> </property> </bean> <bean id="userController" class="controller.AddCountryFormController"> <property name="commandName"><value>country</value></property> <property name="commandClass"><value>controller.Country</value></property> <property name="formView"><value>countryForm</value></property> <property name="successView"><value>countryForm</value></property> </bean> 

AddCountryFormController.java

 package controller; import javax.servlet.http.*; import org.springframework.web.servlet.ModelAndView; import org.springframework.validation.BindException; import org.springframework.web.servlet.mvc.SimpleFormController; public class AddCountryFormController extends SimpleFormController { public AddCountryFormController(){ setCommandName("Country.class"); } protected ModelAndView onSubmit(HttpServletRequest request,HttpServletResponse response,Object command,BindException errors){ Country country=(Country)command; System.out.println("calling onsubmit method !!!!!"); return new ModelAndView(getSuccessView(),"country",country); } } 

Country.java

 package controller; public class Country { private String countryName; public void setCountryName(String value){ countryName=value; } public String getCountryName(){ return countryName; } } 

countryForm.jsp

 <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %> <html> <body> <form:form commandName="country" method="POST" > <table> <tr><td><form:input path="countryName"/></td></tr> <tr><td><input type="submit" value="Save"/></td></tr> </table> </form:form> </body> <html> 

Input page commandName="country" ModelAndView Constructor as return new ModelAndView(getSuccessView(),"country",country); Input tool commandName==ModeAndView(,"commandName",)

Answer 5

We ran into the same problem and changed commandname="" to modelAttribute="" on the jsp page to solve this problem.

Answer 6

I also ran into this problem. Here is my solution:

The following is an error when working with a small Spring Application: -

To solve this problem, you need to do the following in the controller class: -

• Change the import package from " import org.springframework.web.portlet.ModelAndView; " to " import org.springframework.web.servlet.ModelAndView; " ...
• Recompile and run the code ... the problem should be resolved.
