SpringMVC的删除功能

Dao层

package net.roseindia.dao;

import java.util.Date;

import java.util.List;

import net.roseindia.model.Article;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Repository;

@Repository("articleDao")

public class ArticleDaoImpl implements ArticleDao {

  @Autowired

  private SessionFactory sessionFactory;

  // To Save the article detail

  public void saveArticle(Article article) {

    article.setAddedDate(new Date());

    sessionFactory.getCurrentSession().saveOrUpdate(article);

  }

  public void deleteArticle(Integer articleId){

      System.out.println("Dao-->"+articleId);

      Session session=sessionFactory.openSession();

      Article article = (Article) session.get( Article.class,articleId);

      session.beginTransaction();

      if (null != article) {

          session.delete(article);

      }

      session.getTransaction().commit();

      session.close();

  }

  // To get list of all articles

  @SuppressWarnings("unchecked")

  public List<Article> listArticles() {

    return (List<Article>) sessionFactory.getCurrentSession().createCriteria(Article.class).list();

  }

}

Jsp页面如下

<%@  taglib  uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<html>

<head>

<title>All Articles</title>

</head>

<body>

<h1>List Articles</h1>

<a href="articles/add.html">Add Article</a>

<c:if test="${!empty articles}">

<table>

<tr>

<th>Article ID</th>

<th>Article Name</th>

<th>Article Desc</th>

<th>Added Date</th>

</tr>

<c:forEach items="${articles}" var="article">

<tr>

<td><c:out value="${article.articleId}"/></td>

<td><c:out value="${article.articleName}"/></td>

<td><c:out value="${article.articleDesc}"/></td>

<td><c:out value="${article.addedDate}"/></td>

<!-- <td><a href="#" onclick="getData('articles.do?actionMethod=delete&queryId=${article.articleId}','','workspace');">delete</a></td>  -->

<!-- <td><a href="/articles/delete/${article.articleId}">delete</a></td>  -->

<td><a href="articles/delete.do?ID=${article.articleId}">delete</a></td> 

</tr>

</c:forEach>

</table>

</c:if>

</body>

</html>
