实例：SSH结合KindEditor实现新闻的添加、修改和显示功能
最近在学习KindEditor插件，一款蛮不错的编辑器插件。在此将心得写出来，希望对大家有所帮助。
最终实现的效果如图所示：
（1）在管理员页面manage.jsp点击”添加新闻“按钮。
（2）可以从网络上面复制粘贴一篇文章，也可以自己编写文章。现在测试图片从其他网站复制粘贴的情况。
（3）点击提交，提示提交成功后，进入主页面index.jsp，发现刚才编辑的文章已经显示出来。
（4）这时候点击标题，可以正常显示文章来。
（5）除此外还可以实习本地图片的上传，文档的上传下载等功能。还有对上传的文章进行修改等功能。
实现步骤：
1、在Eclipse或者Myeclipse中搭建KindEditor环境，可以查照我先前的博客的做法：
http://blog.csdn.net/lhq13400526230/article/details/9256301
2、在Oracle中设计一张表名为news的数据库表。之所以有主键和业务主键，是为了让业务和主键无关系
3、创建工程，工作的目录如图所示：包括控制层（Action）、模型层（model）、接口（Service）、接口的实现类（ServiceImpl）、Spring配置（applicationContext.xml）、Spring的数据库配置（applicationContext_db.xml）、Spring的依赖注入(applicationContext_bean.xml)、存放上传图片、文件的目录的文件夹attached、存放KindEditor插件的文件夹KindEditor-4.1.7、存放JSP页面的文件夹JSP、存放新闻主页的JSP--index.jsp、存放管理员首页的JSP---manage.jsp等等。
4、web.xml配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- Sttuts2过滤器 --> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>*.action</url-pattern> </filter-mapping> <!-- 监听器Spring --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 定位applicationContext.xml的物理位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> </web-app>
5、applicationContext.xml配置
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<import resource="applicationContext_bean.xml"/>
<import resource="applicationContext_db.xml"/>
</beans>
6、在news.model下编写News.java类
package news.model;
import java.sql.Blob;
import java.util.Date;
public class News {
private String id;//主键
private String newsid;//新闻主键
private String title;//新闻标题
private byte[] content;//新闻内容
private Date times;//新闻发布时间
private String types;//新闻类型
private String author;//新闻作者
private String department;//新闻发布部门
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public byte[] getContent() {
return content;
}
public void setContent(byte[] content) {
this.content = content;
}
public String getNewsid() {
return newsid;
}
public void setNewsid(String newsid) {
this.newsid = newsid;
}
public Date getTimes() {
return times;
}
public void setTimes(Date times) {
this.times = times;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getTypes() {
return types;
}
public void setTypes(String types) {
this.types = types;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
}
7、生成对应的映射文件，其中的大部分是使用String类型的，”内容“字段”content“在数据库中是以BLOB存放，非常的与此不同要注意。
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- Generated 2013-7-5 15:57:38 by Hibernate Tools 3.4.0.CR1 -->
<hibernate-mapping>
<class name="news.model.News" table="NEWS">

</property>
<property name="department" type="java.lang.String">
<column name="DEPARTMENT" />
</property>
</class>
</hibernate-mapping>
8、在news.service下编辑接口NewsService.java
package news.service;
import java.util.List;
import news.model.News;
public interface NewsService {
public String saveNews(News news,String content) throws Exception;//保存编译的新闻
public List findNews(String newsid) throws Exception;//显示新闻内容
public List listNews(String type) throws Exception;//显示新闻列表
public void updateShowNews(News n) throws Exception;//更新新闻
}
9、编写对应的接口实现类
package news.serviceImpl;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import java.util.UUID;
import news.action.NewsAction;
import news.model.News;
import news.service.NewsService;
import org.apache.log4j.Logger;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
public class NewsServiceImpl implements NewsService{
static Logger log = Logger.getLogger(NewsServiceImpl.class);
private SessionFactory sessionFactory;
//保存数据
public String saveNews(News news,String htmlData) throws Exception {
String uuid=UUID.randomUUID().toString();//UUID产生主键
byte content[]=htmlData.getBytes("utf-8");//String类型转化为Byte类型
log.info("信息："+htmlData);
Date date=new Date();//产生时间
DateFormat datefor = new SimpleDateFormat("yyyy-MM-dd-HHmmssFFFF");//时间格式化
String neswid = datefor.format(date);
news.setId(uuid);//设置主键
news.setNewsid(neswid);//设置新闻主键
news.setTimes(date);//设置时间
news.setContent(content);//设置内容
this.sessionFactory.getCurrentSession().save(news);
return neswid;
}
//修改新闻
public void updateShowNews(News n) throws Exception {
this.sessionFactory.getCurrentSession().update(n);
}
//显示新闻的标题栏
public List listNews(String type) throws Exception {
String sql = " from News t where t.types=:types ";
Query query=this.sessionFactory.getCurrentSession().createQuery(sql);
query.setParameter("types", type);//新闻编号
return query.list();
}
//根据新闻业务主键newsid查询新闻
public List findNews(String newsid) throws Exception {
String sql = " from News t where t.newsid=:newsid ";
Query query=this.sessionFactory.getCurrentSession().createQuery(sql);
query.setParameter("newsid", newsid);//新闻编号
return query.list();
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
}
10、编写Spring与数据库的连接配置applicationContext_db.xml
<?xml version="1.0" encoding="UTF-8"?>

</beans>
11、编写Spring的依赖注入配置applicationContext_bean.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

<bean id="news_action" class="news.action.NewsAction">
<property name="news_services">
<ref bean="news_service" />
</property>
</bean>
</beans>
12、在news.action下编程NewsAction.java
package news.action;
import java.io.UnsupportedEncodingException;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import java.util.Map;
import java.util.UUID;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import news.model.News;
import news.service.NewsService;
import org.apache.log4j.Logger;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionContext;
public class NewsAction {
static Logger log = Logger.getLogger(NewsAction.class);
private NewsService news_services;
private News news;
//保存编辑的新闻信息
public String saveNews() throws Exception {
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();
String htmlData = request.getParameter("content1");//获取页面的数据
news_services.saveNews(news,htmlData);
return "saveNewsSuccess";
}
//获取要更新新闻的信息
public String updateContent() throws Exception {
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();
String htmlData=request.getParameter("content1");
log.info("新闻的主键============="+news.getId());
log.info("新闻的内容============="+htmlData);
byte content[]=htmlData.getBytes("utf-8");
news.setContent(content);
news_services.updateShowNews(news);
return "updateContentSuccess";
}
//查找新闻的详细信息
public String showNews() throws Exception{
HttpServletResponse response = ServletActionContext.getResponse();
HttpServletRequest request = ServletActionContext.getRequest();
String newsid=news.getNewsid();//从页面获取要查看的新闻ID
List list=news_services.findNews(newsid);
News n=(News) list.get(0);
DateFormat datefor = new SimpleDateFormat("yyyy-MM-dd HH:mm");//时间格式化
String times = datefor.format(n.getTimes());
String CONTENT=new String(n.getContent());//将byte数组转化为String类型
String auhtor=n.getAuthor();
String title=n.getTitle();
String types=n.getTypes();
String department=n.getDepartment();
String id=n.getId();
String no=n.getNewsid();
request.setAttribute("id", id);
request.setAttribute("newsid", no);
request.setAttribute("department", department);
request.setAttribute("title", title);
request.setAttribute("types", types);
request.setAttribute("content", CONTENT);
request.setAttribute("times", times);
request.setAttribute("author", auhtor);
return "showNewsSuccess";
}
//分别罗列出各个新闻的列表
public String NewsList() throws Exception{
Map request = (Map) ActionContext.getContext().get("request");//属于
List list=news_services.listNews("国际新闻");
request.put("list_guoji", list);
List list2=news_services.listNews("国内新闻");
request.put("list_guonei", list2);
List list3=news_services.listNews("体育新闻");
request.put("list_tiyu", list3);
List list4=news_services.listNews("娱乐新闻");
request.put("list_yule", list4);
return "sucess";
}
public NewsService getNews_services() {
return news_services;
}
public void setNews_services(NewsService news_services) {
this.news_services = news_services;
}
public News getNews() {
return news;
}
public void setNews(News news) {
this.news = news;
}
}
13、编程Struts.xml的配置
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.multipart.saveDir" value="/tmp"></constant> <package name="default" extends="struts-default"> <action name="saveNewsAction" class="news_action" method="saveNews"> <result name="saveNewsSuccess">/jsp/success.jsp</result><!--保存编辑信息信息成功跳转页面 --> </action> <action name="showNewsAction" class="news_action" method="showNews"> <result name="showNewsSuccess">/jsp/show_news_content.jsp</result><!--读取新闻信息 --> </action> <action name="showNewsListAction" class="news_action" method="NewsList"> <result name="sucess">/jsp/show_news_list.jsp</result><!--读取新闻列表信息 --> </action> <action name="manageNewsListAction" class="news_action" method="NewsList"> <result name="sucess">/jsp/manage_news_list.jsp</result><!--读取新闻列表信息 --> </action> <action name="updateNewsAction" class="news_action" method="showNews"> <result name="showNewsSuccess">/jsp/manage_news_content.jsp</result><!--读取新闻列表信息 --> </action> <action name="updateContentAction" class="news_action" method="updateContent"> <result name="updateContentSuccess">/jsp/updateSuccess.jsp</result><!--修改新闻列表信息 --> </action> </package> </struts>
14、现在进入前台JSP页面的编写，主要的页面有如下：
15、index.jsp用于新闻网站的首页
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<%
request.setCharacterEncoding("UTF-8");
%>
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<title>新闻主页</title>
</head>
<body >
<div align="center">
<table>
<tr>
<td><h2 align="center">新闻频道</h2></td>
</tr>
<tr>
<td>
<iframe id="mainframe" src="showNewsListAction.action"
name="mainframe" frameborder="0" scrolling="no" width="800px"
height="100%"> </iframe></td>
</tr>
</table>
</div>
</body>
<script type="text/javascript">
function reinitIframe(){
var iframe = document.getElementById("mainframe");
try{
var bHeight = iframe.contentWindow.document.body.scrollHeight;
var dHeight = iframe.contentWindow.document.documentElement.scrollHeight;
var height = Math.max(bHeight, dHeight);
iframe.height = height;
}catch (ex){}
}
window.setInterval("reinitIframe()", 200);
</script>
</html>
16、show_news_list.jsp用于显示查询到已经发表的新闻列表。显示的只是新闻的标题，不是内容。
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<%
request.setCharacterEncoding("UTF-8");
String htmlData = request.getParameter("content1") != null ? request
.getParameter("content1") : "";
%>
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<title>新闻显示列表页面</title>
</head>
<body>

</s:iterator>
</table>
</div>
<div style="float:left;width:350px;height:200px;">
<table>

</tr>
</s:iterator>
</table>
</div>
</body>
</html>
17、show_news_content.jsp显示具体的新闻内容
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
request.setCharacterEncoding("UTF-8");
%>

</tr>
</table>
</div>
<hr>
<div>
<%=request.getAttribute("content")%>
</div>
</div>
</body>
</html>
18、manage.jsp管理员的主页面
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<%
String path = request.getContextPath();
request.setCharacterEncoding("UTF-8");
