org.springframework.context.NoSuchMessageException: No message found under code 'required.name.dukeCommand.name' for locale 'en_US'

[RajaSekhar]

Hi Sang,

I am getting below exception while doing - homework_spring3_mvc_form homework

1)Attached error log

2) DukeController code

package com.raja.examples.hellodukes.controllers;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.ModelMap;

import org.springframework.validation.BindingResult;

import org.springframework.web.bind.annotation.ModelAttribute;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.support.SessionStatus;

import com.raja.examples.hellodukes.domain.Duke;

import com.raja.examples.hellodukes.validators.DukeValidator;

@Controller

@RequestMapping(value="/HelloDuke")

public class DukeController {

DukeValidator dukeValidator;

@Autowired

public DukeController(DukeValidator dukeValidator){

this.dukeValidator = dukeValidator;

}

@RequestMapping(method = RequestMethod.GET)

public String getCreateForm(ModelMap model){

Duke duke = new Duke();

// Set Name field

duke.setName("Raja");

// Set "Mastering" as default checked value

duke.setHobby("golf");

// Save the command object as "student" so that

// the "StudentForm" view access it.

model.addAttribute("dukeCommand", duke);

// Return form view

return "dukeForm";

}

//Handle form submission. 

@RequestMapping(method = RequestMethod.POST)

public String processSubmit(

@ModelAttribute("dukeCommand") Duke duke,

BindingResult result, SessionStatus status) {

// Perform validation

dukeValidator.validate(duke, result);

if (result.hasErrors()) {

// If validation failed, display the form page again

return "dukeForm";

} else {

status.setComplete();

// If validation succeeded, return "StudentSuccess" 

return "dukeForm2";

}

}

}

3) DukeValidator Code:

package com.raja.examples.hellodukes.validators;

import org.springframework.validation.Errors;

import org.springframework.validation.ValidationUtils;

import org.springframework.validation.Validator;

import com.raja.examples.hellodukes.domain.Duke;

public class DukeValidator implements Validator{

public boolean supports(Class clazz) {

//just validate the Student instances

return Duke.class.isAssignableFrom(clazz);

}

public void validate(Object target, Errors errors) {

ValidationUtils.rejectIfEmptyOrWhitespace(errors, "name",

"required.name", "Field name is required.");

ValidationUtils.rejectIfEmptyOrWhitespace(errors, "hobby",

"required.hobby", "Field hobby is required.");

Duke cust = (Duke)target;

if((cust.getName().length() < 5 || cust.getName().length() > 10)){

errors.rejectValue("name", "required.name");

}

}

}

4) messages.properties

required.name = Username is required2!

required.hobby = Address is required!

length.name=name should be within 5 - 10 chars!

Please suggest where I mistaken.

Thanks

Raja

Hi Sang,

The error says

No message found under code 'required.name.dukeCommand.name' for locale 'en_US'
and your messages.properties below does not seem to have a message for
'required.name.dukeCommand.name'

required.name = Username is required2!

required.hobby = Address is required!

length.name=name should be within 5 - 10 chars!

It is hard to tell why the properties file is not being accessed just by looking at
your code unfortunately.

When I set logs in Controller, for different errors in validators

1)

inside haserrors------org.springframework.validation.BeanPropertyBindingResult: 1 errors

Field error in object 'dukeC' on field 'name': rejected value []; codes [required.name.dukeC.name,required.name.name,required.name.java.lang.String,required.name]; arguments []; default message [Field name is required.]

2)

inside haserrors------org.springframework.validation.BeanPropertyBindingResult: 1 errors

Field error in object 'dukeC' on field 'name': rejected value [Raja]; codes [required.name.dukeC.name,required.name.name,required.name.java.lang.String,required.name]; arguments []; default message [null]

So, I changed the code as below and its working as alternative,

public class DukeValidator implements Validator{

public boolean supports(Class clazz) {

//just validate the Student instances

return Duke.class.isAssignableFrom(clazz);

}

public void validate(Object target, Errors errors) {

ValidationUtils.rejectIfEmptyOrWhitespace(errors, "name",

"required.name", "Field name is required.");

ValidationUtils.rejectIfEmptyOrWhitespace(errors, "hobby",

"required.hobby", "Field hobby is required.");

Duke cust = (Duke)target;

if((cust.getName().length() < 5 || cust.getName().length() > 10)){

errors.rejectValue("name", "required.name","Name should be within 5 to 10 chars");

// added third param, ' default message' and its taking default message rather than from the message.properties.

}

}

here still my questions is : How to get error messages from properties ? Seems like they are not getting triggered.

Thanks

Duke cust = (Duke)target;

if((cust.getName().length() < 5 || cust.getName().length() > 10)){

errors.rejectValue("name", "required.name"); // the code is failing when this line gets executed. when I have given required.name why its not looking up for this particular message key ? . dukeCommand is messageAttribute given from Controller class. Im confused here.

}

}
