这是用.net2.0开发的一个基于ExtSJ技术实现的简单blog系统,演示了ExtJS的综合应用。
系统后台使用.Net平台,语言为C#,技术构架为NHibernate+Spring.Net+Vifir实现,支持多种数据库,采用三层结构,数据访问层DAO、业务逻辑层及表示层完全分离。DAO层使用的泛型DAO,只需要一个DAO接口即可,不需要写具体的实现。

系统中的一些源码摘要:
域模型:
namespace Vifir.Model.Domain
{
public class Topic
{
private long id;
private string title;
private string content;
private string intro;
private TopicCategory category;
private IList<TopicComment> comments = new List<TopicComment>();
private DateTime inputTime = DateTime.Now;
private int readTimes = 0;
public virtual long Id
{
get { return id; }
set { id = value; }
}
public virtual string Title
{
get { return title; }
set { title = value; }
}
public virtual string Content
{
get { return content; }
set { content = value; }
}
public virtual string Intro
{
get { return intro; }
set { intro = value; }
}
public virtual TopicCategory Category
{
get { return category; }
set { category = value; }
}
public virtual IList<TopicComment> Comments
{
get { return comments; }
set { comments = value; }
}
public virtual DateTime InputTime
{
get { return inputTime; }
set { inputTime = value; }
}
public virtual int ReadTimes
{
get { return readTimes; }
set { readTimes = value; }
}
}
}
{
public class Topic
{
private long id;
private string title;
private string content;
private string intro;
private TopicCategory category;
private IList<TopicComment> comments = new List<TopicComment>();
private DateTime inputTime = DateTime.Now;
private int readTimes = 0;
public virtual long Id
{
get { return id; }
set { id = value; }
}
public virtual string Title
{
get { return title; }
set { title = value; }
}
public virtual string Content
{
get { return content; }
set { content = value; }
}
public virtual string Intro
{
get { return intro; }
set { intro = value; }
}
public virtual TopicCategory Category
{
get { return category; }
set { category = value; }
}
public virtual IList<TopicComment> Comments
{
get { return comments; }
set { comments = value; }
}
public virtual DateTime InputTime
{
get { return inputTime; }
set { inputTime = value; }
}
public virtual int ReadTimes
{
get { return readTimes; }
set { readTimes = value; }
}
}
}
DAO接口
namespace Vifir.Model.DAO
{
public interface ITopicDAO : GenericDAO
{
}
}
{
public interface ITopicDAO : GenericDAO
{
}
}
泛型DAO配置
<object id="TopicDao" parent="abstractDao"> <property name="proxyInterfaces" value="Vifir.Model.DAO.ITopicDAO"/> <property name="target"> <object parent="baseDAO" type="Vifir.Core.GenericDAOImpl<Vifir.Model.Domain.Topic>,Vifir.Core" /> </property> </object>
TopicService业务层实现代码
namespace Vifir.Model.Service.Impl
{
public class TopicServiceImpl:ITopicService
{
private ITopicDAO topicDao;
public ITopicDAO TopicDao
{
set { topicDao = value; }
}
public long addTopic(Topic topic) {
this.topicDao.Save(topic);
return topic.Id;
}
public Topic getTopic(long id) {
Topic topic = this.topicDao.Get(id);
return topic;
}
public bool delTopic(long id) {
Topic topic = this.getTopic(id);
if(topic.Comments.Count>0)throw new LogicException("该文章下还有评论,不能删除!");
if (topic != null) {
this.topicDao.Remove(id);
return true;
}
return false;
}
public IPageList getTopicBy(IQueryObject queryObject) {
return QueryUtil.query(queryObject, typeof(Topic),this.topicDao);
}
public bool updateTopic(long id, Topic topic) {
if (id != default(long))
{
topic.Id=id;
} else {
return false;
}
this.topicDao.Update(topic);
return true;
}
}
}
{
public class TopicServiceImpl:ITopicService
{
private ITopicDAO topicDao;
public ITopicDAO TopicDao
{
set { topicDao = value; }
}
public long addTopic(Topic topic) {
this.topicDao.Save(topic);
return topic.Id;
}
public Topic getTopic(long id) {
Topic topic = this.topicDao.Get(id);
return topic;
}
public bool delTopic(long id) {
Topic topic = this.getTopic(id);
if(topic.Comments.Count>0)throw new LogicException("该文章下还有评论,不能删除!");
if (topic != null) {
this.topicDao.Remove(id);
return true;
}
return false;
}
public IPageList getTopicBy(IQueryObject queryObject) {
return QueryUtil.query(queryObject, typeof(Topic),this.topicDao);
}
public bool updateTopic(long id, Topic topic) {
if (id != default(long))
{
topic.Id=id;
} else {
return false;
}
this.topicDao.Update(topic);
return true;
}
}
}
Web层的添删改查代码:
public partial class manage_Topic : BaseAction
{
private ITopicService service;
private ITopicCategoryService categoryService;
public ITopicService Service
{
set { service = value; }
}
public ITopicCategoryService CategoryService
{
set { categoryService = value; }
}
public void List()
{
QueryObject qo = new QueryObject();
ToPo(qo);
string categoryId = Request.Params["categoryId"];
if (categoryId != null && !"".Equals(categoryId))
{
qo.addQuery("obj.Category.id", long.Parse(categoryId), "=");
}
IPageList pageList = service.getTopicBy(qo);
jsonResult = pageList;
}
public
{
private ITopicService service;
private ITopicCategoryService categoryService;
public ITopicService Service
{
set { service = value; }
}
public ITopicCategoryService CategoryService
{
set { categoryService = value; }
}
public void List()
{
QueryObject qo = new QueryObject();
ToPo(qo);
string categoryId = Request.Params["categoryId"];
if (categoryId != null && !"".Equals(categoryId))
{
qo.addQuery("obj.Category.id", long.Parse(categoryId), "=");
}
IPageList pageList = service.getTopicBy(qo);
jsonResult = pageList;
}
