以上代码是问题代码 我能保证struts.xml的配置肯定没问题 action种之前我用的是indexdao hql能查出来数据 换成basedao就抛异常了 但是下面的action用basedao却没问题 请看代码
public class ArticleAction extends ActionSupport {
private static final long serialVersionUID = -5722778083187717369L;
private int aid = 0;
private BaseDAO<Article> baseDAO = new BaseDAO<Article>();
private List<Article> article = new ArrayList<Article>();
private TreeMap<String,Integer> tags_map;
private String key = "";
private int page = 0;
private IArticleManage articleManage;
.......................getset方法省略...............
public String main(){
article = baseDAO.list(" from Article where del_flag = '0' order by cre_date desc ");
return "main";
}
public String hot(){
article = baseDAO.list(" from Article where del_flag = '0' order by pvs desc ");
return "hot";
}
public String recommend(){
article = baseDAO.list(" from Article where recommend ='1' and del_flag = '0' order by cre_date desc ");
return "recommend";
}
public String details(){
article = baseDAO.list(" from Article where id='"+aid+"' and del_flag = '0' ");
return "details";
}
public String list(){
article = baseDAO.list(" from Article where tags like'%"+key+"%' and del_flag = '0' ");
return "list";
}
}
哎呀好紧张 小白都不知道怎么组织语言了
我的意思是什么呢 恩 我细点说
上面的IndexAction 是不好用的代码 ArticleAction 这个是好用的
之前呢 我没用baseDAO 全是各个的dao用hql查询的数据 都没问题 后来我把这些简单的语句改成同意用DAO查询
上面的indexaction中三个其他类型的basedao不好用 应该是spring的配置问题吧 我猜是
而下面的ArticleAction 中basedao类型就是article的 就好用
而且不好用的action中recommend() notice() download() 方法都不进断点 是不是页面里面的s:action 加载的时候就抛异常了
下面贴上异常

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type
没有配置的bean但是你却用了，抛出异常，检测看下action是否用了没配置的bean数据

好长
检查下 indexAction 的配置

下面是basedao
应该跟这个没啥关系吧
public class BaseDAO<T> {
//插入数据
public void create(T object){
Session session = HibernateUtil.getSessionFactory().openSession();
try {
session.beginTransaction();
session.persist(object);
session.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
session.getTransaction().rollback();
} finally {
session.close();
}
}
//更新数据
public void update(T object){
Session session = HibernateUtil.getSessionFactory().openSession();
try {
session.beginTransaction();
session.update(object);
session.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
session.getTransaction().rollback();
} finally {
session.close();
}
}
//删除数据
public void delete(T object){
Session session = HibernateUtil.getSessionFactory().openSession();
try {
session.beginTransaction();
session.delete(object);
session.getTransaction().commit();
} catch (Exception e) {
e.printStackTrace();
session.getTransaction().rollback();
} finally {
session.close();
}
}
//根据id查找数据
@SuppressWarnings("unchecked")

session.beginTransaction();
return (T)session.get(clazz, id);
} catch (Exception e) {
e.printStackTrace();
session.getTransaction().rollback();
return null;
} finally {
session.getTransaction().commit();
session.clear();
}
}
@SuppressWarnings("unchecked")
public List<T> list(String hql){
Session session = HibernateUtil.getSessionFactory().openSession();
try {
session.beginTransaction();
