I have a question regarding Spring MVC .
I'm developing a system using HTML5 in View , and as a renderer I'm using thymeleaf .
For example, if I have a class Produto , and it has a list of Endereços , is there a way for me to add in the list, considering that springmvc is framework action based ?
Class: Product
List: Addresses
Goal: Add an item to the list through the view.
You can use a submit in your view, which takes the required parameters to your address list and takes you to your method, for example:
View code:
<form th:action="@{/produtos/addEndereco}" th:object="${endereco}" method="POST">
<input type="text" placeholder="Logradouro"
th:field="*{logradouro}"/>
<input type="number" placeholder="numero" th:field="*{numero}"/>
<button type="submit">Adicionar</button>
</form>
In your controller, you will call the method that adds an item to the list.
Controller:
@Controller
@RequestMapping("/produtos")
public class ProdutosController{
@Autowired
Produtos produtos;
@RequestMapping(value="/addEndereco",method = RequestMethod.POST)
public String adicionarEndereco(Endereco endereco){
this.produtos.addEndereco(endereco);
return "redirect:/produtos";
}
}
Model:
@Service
public class Produtos {
private static List<Endereco> enderecos = new ArrayList<>();
public void addEndereco(Endereco endereco){
enderecos.add(endereco);
}
}
And your address bean:
public class Endereco {
String logradouro;
int numero;
...
}
