SSH整合项目（新闻发布）

一个简单的S2SH的整合新闻案例，今天给大家分享一下。该项目使用的ORACLE数据库

+Hibernate+Struts2+Spring 。希望可以对大家起到帮助

1.oracle创建用户和表

--创建表空间
create tablespace superhang 
logging
datafile 'd:/superhang.dbf'
size 32m
autoextend on
next 32m maxsize 2048m
extent management local;

--创建临时表空间
create temporary tablespace bocodbtempdbs 
tempfile 'd:/bocodbtempdbs01.dbf' 
size 32m 
autoextend on 
next 32m maxsize 2048m
extent management local;

create user xuhang identified by svse 
default tablespace superhang
temporary tablespace bocodbtempdbs;

--授权
grant connect,resource to xuhang;

--查看所有表空间
select dbf.tablespace_name,
dbf.totalspace "总量(M)",
dbf.totalblocks as 总块数,
dfs.freespace "剩余总量(M)",
dfs.freeblocks "剩余块数",
(dfs.freespace / dbf.totalspace) * 100 "空闲比例" 
from (select t.tablespace_name,
sum(t.bytes) / 1024 / 1024 totalspace,
sum(t.blocks) totalblocks
from dba_data_files t
group by t.tablespace_name) dbf,
(select tt.tablespace_name,
sum(tt.bytes) / 1024 / 1024 freespace,
sum(tt.blocks) freeblocks
from dba_free_space tt
group by tt.tablespace_name) dfs
where trim(dbf.tablespace_name) = trim(dfs.tablespace_name)

--创建news表
create table news
(
nid number  primary key ,
kid number references userinfo(id),
ntitle varchar2(50)  not null,
ncontext varchar2(500)  not null,
ntime varchar2(50)  not null
)

--创建发布人表
create table userinfo
(
 id number primary key,
 uname varchar2(50) not null,
 upsw varchar2(50) not null,
 urealname varchar2(50) not null      
)

--创建序列
create sequence user_seq
minvalue 1
maxvalue 999999999
start with 1
increment by 1
cache 20; 

--创建序列
create sequence news_seq
minvalue 1
maxvalue 999999999
start with 1
increment by 1
cache 20; 



insert into userinfo values (user_seq.Nextval,'admin','123456','张三');
insert into news values(news_seq.Nextval,2,'张三成功的登上了月球','月球，俗称月亮，古时又称太阴、玄兔，是地球唯一的天然卫星，并且是太阳系中第五大的卫星','2014-5-21');
insert into news values(news_seq.Nextval,2,'世界末日什么时候来','xxxxx','2014-5-22');
insert into news values(news_seq.Nextval,2,'amazeUI很不错','xxxxxxxx','2014-5-23');
select * from userinfo;
select * from news;

2.搭建SSH的环境

导入时Spring时勾选这5个包

导入Struts时勾选这2个包

导入hibernate勾选这2个包

3.项目搭建好了。我们就可以编写业务逻辑了

web.xml文件加入2（listener和filter）个配置

		org.springframework.web.context.ContextLoaderListener
	
	
	
	
		 contextConfigLocation
		 classpath:applicationContext.xml
	
  
  	struts2
  	
  		org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
  	
  
  
  	struts2
  	/*
  

--dao层，使用接口的编写方式，定义2个接口

package xander.dao;

import java.util.List;

import xander.entity.News;

public interface NewsDAO {
	public List getAllNews();
	public void addNews(News news);
}

package xander.dao;

import xander.entity.Userinfo;

public interface UserDAO {
	public Userinfo getUser(String uname,String upsw);
}

--2接口的实现类DAOImpl

package xander.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;

import xander.dao.NewsDAO;
import xander.entity.News;

@Repository("newsDAO")
public class NewsDAOImpl implements NewsDAO{
	
	@Resource
	private HibernateTemplate hibernateTemplate;
	public void addNews(News news) {
		hibernateTemplate.save(news);
		
	}

	public List getAllNews() {
		List news =hibernateTemplate.find("from News");
		return news;
	}

}

package xander.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;

import xander.dao.UserDAO;
import xander.entity.Userinfo;

@Repository("userDAO")
public class UserDAOImpl implements UserDAO{
	@Resource
	private HibernateTemplate hibernateTemplate;
	
	public Userinfo getUser(String uname, String upsw) {
		String hql = "from Userinfo u where u.uname = ? and u.upsw = ?";
		List userinfos = hibernateTemplate.find(hql, uname,upsw);
		if(userinfos==null || userinfos.size()==0){
			return null;
		}
		return userinfos.get(0);
	}

}

--service层也是使用2个接口

package xander.service;

import java.util.List;

import xander.entity.News;

public interface NewsService {
	public List getAllNews();
	public void addNews(News news);
}

package xander.service;

import xander.entity.Userinfo;

public interface UserService {
	public Userinfo getUser(String uname,String upsw);
}

--service接口的实现类

package xander.service;

import xander.entity.Userinfo;

public interface UserService {
	public Userinfo getUser(String uname,String upsw);
}

package xander.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import xander.dao.UserDAO;
import xander.entity.Userinfo;
import xander.service.UserService;
@Service("userService")
public class UserServiceImpl implements UserService{
	
	@Resource
	private UserDAO userDAO;
	public Userinfo getUser(String uname, String upsw) {
		// TODO Auto-generated method stub
		return userDAO.getUser(uname, upsw);
	}

}

--接下里我们就可以编写action类

一个UserAction处理登录

package xander.action;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;

import javax.annotation.Resource;
import javax.xml.crypto.Data;

import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import xander.entity.News;
import xander.service.NewsService;

import com.opensymphony.xwork2.ActionSupport;

@Controller("newsAction")
@Scope("prototype")
public class NewsAction extends ActionSupport {
	private News snews;
	@Resource
	private NewsService newsService;
	
	private List news;

	public News getSnews() {
		return snews;
	}

	public void setSnews(News snews) {
		this.snews = snews;
	}

	public List getNews() {
		return news;
	}

	public void setNews(List news) {
		this.news = news;
	}

	public String addUI() throws Exception {
		
		return "addUI";
	}
	
	public String add() throws Exception {
		Date date = new Date();
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
		String ntime =sdf.format(date);
		
		snews.setNtime(ntime);
		
		newsService.addNews(snews);
		// 获取新闻列表
		news = newsService.getAllNews();
		return "list";
	}
	
	
}

--NewsAction处理新闻的显示

package xander.action;

import java.util.List;
import java.util.Map;

import javax.annotation.Resource;

import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import xander.entity.News;
import xander.entity.Userinfo;
import xander.service.NewsService;
import xander.service.UserService;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

@Controller("userAction")
@Scope("prototype")
public class UserAction extends ActionSupport{
	@Resource
	private UserService userService;
	@Resource
	private NewsService newsService;
	private List news;
	
	
	public List getNews() {
		return news;
	}

	public void setNews(List news) {
		this.news = news;
	}


	private Userinfo userinfo;

	public Userinfo getUserinfo() {
		return userinfo;
	}

	public void setUserinfo(Userinfo userinfo) {
		this.userinfo = userinfo;
	}
	
	
	//登录
	public String login() throws Exception {
		Userinfo user = userService.getUser(userinfo.getUname(), userinfo.getUpsw());
		if(user !=null){
			Map map = ActionContext.getContext().getSession();
			map.put("user", user);
			news = newsService.getAllNews();
			return "list";
		}else{
			ActionContext.getContext().put("msg", "你输入的用户名或密码有误！");
			return INPUT;
		}
		
	}
}

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;


import javax.annotation.Resource;
import javax.xml.crypto.Data;


import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;


import xander.entity.News;
import xander.service.NewsService;


import com.opensymphony.xwork2.ActionSupport;


@Controller("newsAction")
@Scope("prototype")
public class NewsAction extends ActionSupport {
private News snews;
@Resource
private NewsService newsService;

private List news;

public News getSnews() {
return snews;
}


public void setSnews(News snews) {
this.snews = snews;
}


public List getNews() {
return news;
}


public void setNews(List news) {
this.news = news;
}


public String addUI() throws Exception {

return "addUI";
}

public String add() throws Exception {
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
String ntime =sdf.format(date);

snews.setNtime(ntime);

newsService.addNews(snews);
// 获取新闻列表
news = newsService.getAllNews();
return "list";
}


}

--struts的配置文件如下

	
	
	
		
			/show_news.jsp
			/index.jsp
		
	
	
		
			/news_addUI.jsp
			/show_news.jsp
		
	
    

--applicationContext配置文件：

	
	
		
		
		
		
		
		
	
	
		
	
	
		
			
		
		
			
				
					org.hibernate.dialect.Oracle9Dialect
				
			
		
		
			
				xander/entity/News.hbm.xml
				xander/entity/Userinfo.hbm.xml
		

   

--3个JSP页面如下

1.登录页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>




  
	  
    
    
	
  
  
  
   	

   		

   		 	

			    

			      
新闻发布系统后台管理
			    
  			
   			

   				

   					
帐号：
   					

   				
   				

   					
密码：
   					

   				
   			
   			

   				

   					
 
   				
  				
   			
   			
   		
   	
  

--新闻显示页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>



  

    
    
	  
	
  
  
  
   		
					

   			

   				

   					
编号
   					
标题
   					
发布时间
   					
发布人
   				
	
   			
   			
   			

				

						
 
						

						

						
${sessionScope.user.urealname}
					
				   			
   			
  			
  			

  				

  					
发布新闻 
  				
  			
	
   		
  

--新闻添加页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>



  
   
    
    
    
  
  
  
    
    	
    	
    	
    	
    	
    
  

完成之后的效果：

到这里我们的项目就做完了，一个简易新闻SSH整合就结束了，我们使用了部分注解的方式
