title: how to integrate the jdbcdaosupport to spring mvc3
body: <p>I am using the spring mvc3 in my applicatio,and in the dao layer I want to use jdbctemplate,however I do not know where to add the dao,in the controller?</p>
  
  <p>For example:</p>
  
  <pre><code>@Controller
  public class UserController{
    private UserDao udao;
    public String list(Model model){
      udao=new UserDaoImple();
      List&lt;User&gt; users=udao.list();
      model.addAttrubut('users',users);
      return "list";
    }
  }
  </code></pre>
  
  <p>The above code is just an example,I want to know where to create the userdao?</p>
  
  <p>Also,since I want to use the jdbctemplate,and it is recommended that the jdbctemplate is created only once for one datasourece,so how to make all the daos use the same jdbctemplate?</p>
