  1. POWhat is a generic way to "pass" the data from Spring FORM to DAO?
    text
    copied!<p>I am implementing a basic login form in <strong>Spring Web MVC Framework</strong>. My goal is the following: </p> <ol> <li>Get the <strong><em>username</em></strong> and <strong><em>password</em></strong> from a user</li> <li>Process it i.e. find out if username and password are <strong>matching</strong> those from a DB</li> <li>Return response - login SUCCESSFUL or FAILURE </li> </ol> <p>I successfully obtain all the information from a user with my controller but unfortunately I get stuck at the second point because I don't know exactly how is Spring dealing with such situations.</p> <p>I imagine in this way: <strong>DAO</strong> is an <strong>interface</strong> which is responsible to transfer data from a form on one side and the DB on the otherside. Everything else is MAGIC for me at this point.</p> <p>Please <strong>enlighten me</strong>!</p> <h2>-------------------------------------------------------------------------------------</h2> <p><em>login.jsp</em></p> <hr> <pre class="lang-jsp prettyprint-override"><code>&lt;!-- code --&gt; &lt;div class="content"&gt; &lt;table&gt; &lt;tr&gt; &lt;td&gt;&lt;form:label path="username"&gt;Username&lt;/form:label&gt;&lt;/td&gt; &lt;td&gt;&lt;form:input path="username" /&gt;&lt;/td&gt; &lt;td&gt;&lt;form:errors path="username" cssClass="error"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;form:label path="password"&gt;Password&lt;/form:label&gt;&lt;/td&gt; &lt;td&gt;&lt;form:input path="password" /&gt;&lt;/td&gt; &lt;td&gt;&lt;form:errors path="password" cssClass="error"/&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; &lt;!-- code --&gt; </code></pre> <p><em>FormDao.java</em></p> <hr> <pre class="lang-java prettyprint-override"><code>package si.src.dataAccess; import si.src.forms.Obrazec; public interface FormDao { /* DAO methods */ public void saveForm(Obrazec obrazec); } </code></pre> <p><em>FormDaoImpl.java</em></p> <hr> <pre class="lang-java prettyprint-override"><code>package si.src.dataAccess; import org.springframework.stereotype.Repository; import si.src.forms.Obrazec; @Repository public class FormDaoImpl implements FormDao{ public void saveForm(Obrazec obrazec) { // TODO Auto-generated method stub } } </code></pre> <p>==================================================================================</p>
