Validation Bean Is Not Validating

Hi.

I would like to create a program, where I write a task and it would save it in a database. With this I have a class called, which asks for the description to have at least 5 characters 

package br.com.domain;

import javax.validation.constraints.Size;

public class Tarefa {

    private int id;

    @Size(min=5, message="Deve ter pelo menos 5 caracteres")
    private String descricao;

    private boolean finalizado;

    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }

    public String getDescricao() {
        return descricao;
    }
    public void setDescricao(String descricao) {
        this.descricao = descricao;
    }
    public boolean isFinalizado() {
        return finalizado;
    }
    public void setFinalizado(boolean finalizado) {
        this.finalizado = finalizado;
    }




}

The.jsp form is the field to enter the job description

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="prefix"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <form:errors path="tarefa.descricao" cssStyle="color:red"/>
    <h3>Adicionar Tarefas</h3>
    <form action="adcionaTarefa" method="post">
        Descrição:</br>
        <textarea rows="5" cols="100" name="descricao"></textarea>
        <input type="submit" value="Adcionar">
    </form>

</body>
</html>

And Sistemacontroller.java serves to make your action, if the description is valid it will go to a page saying that the task was successfully added, if not, back to the form page with the error message.

package br.com.Sistema.Controller;

import javax.validation.Valid;

import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import br.com.domain.Tarefa;

@Controller
@RequestMapping("/sistema")
@Validated
public class SistemaController {
    @RequestMapping("/index")
    public ModelAndView teste() {
        ModelAndView mav = new ModelAndView("tarefa/teste");
        return mav;
    }

    @RequestMapping("/formulario")
    public ModelAndView formulario() {
        ModelAndView mav = new ModelAndView("tarefa/formulario");
        return mav;
    }

    @RequestMapping("/adcionaTarefa")
    public ModelAndView adciona(@Valid Tarefa tarefa, BindingResult result) {
        if(result.hasFieldErrors()) {
            ModelAndView mav = new ModelAndView("tarefa/formulario");
            return mav;
        }
        ModelAndView mav = new ModelAndView("tarefa/adcionada");
        return mav;
    }

}

The problem: The Controller is not doing the job of validating the Task, so it goes to the successfully saved task page, regardless of the description, even if I write nothing in the field, what I do to make the program "validate" the task?

It seems to me a problem of configuration of spring Validator, try to change the settings as below:

Configuration by xml:

<mvc:annotation-driven />
<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

Utilizing @Configuration:

@Configuration
public class ValidatorConfig {
    @Bean
    public javax.validation.Validator localValidatorFactoryBean() {
        return new LocalValidatorFactoryBean();
    }   
}
