Opa Guilherme, pela exception parece que você ta chamando o método dentro dele mesmo, o que resulta no stackoverflow mostrado no erro. Pode dar uma olhada? Se não descobrir, posta o código da configuração do messagesource aqui.

Bom dia Alberto,

Segue meu codigo?

package br.com.controletc.conf;

import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

import br.com.controletc.controllers.HomeController;
import br.com.controletc.daos.UsuarioDAO;

@EnableWebMvc
@ComponentScan(basePackageClasses={HomeController.class, UsuarioDAO.class})
public class AppWebConfiguration {

    @Bean
    public InternalResourceViewResolver internalResourceViewResolver(){
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }

    @Bean
    public MessageSource messageSource(){
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();

        messageSource.setBasename("/WEB-INF/messages");
        messageSource.setDefaultEncoding("UTF-8");
        messageSource.setCacheSeconds(1);
        return messageSource();
    }

}

solução!

Exatamente o que estava acontecendo comigo, ao inves de retornar o objeto messageSource, esta retornando o proprio metodo causando o stackoverflow obrigado alberto.


@Bean
    public MessageSource messageSource() {

        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("/WEB-INF/messages");
        messageSource.setDefaultEncoding("UTF-8");
        messageSource.setCacheSeconds(1);

        return messageSource; // ao inves de messageSource();
    }
