一、存储新闻dao方法
在NewsDao.java中新增存储新闻的saveOrupdate方法
public void saveOrupdate(News news){
getSession().saveOrUpdate(news);
}二、存储新闻service方法
在NewsService.java中新增存储新闻的saveOrupdate方法
public void saveOrupdate(News news){
newsDao.saveOrupdate(news);
}三、存储新闻action
让NewsAction实现ModelDriven和Preparable接口，并实现其抽象方法。
package cn.ac.ucas.action;
import java.util.Map;
import org.apache.struts2.interceptor.RequestAware;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.opensymphony.xwork2.Preparable;
import cn.ac.ucas.form.News;
import cn.ac.ucas.service.NewsService;
public class NewsAction extends ActionSupport implements RequestAware, ModelDriven<News>, Preparable {
private static final long serialVersionUID = 1L;
private Map<String, Object> request;
private NewsService newsService;
private News model;
@Override
public void setRequest(Map<String, Object> arg0) {
// TODO Auto-generated method stub
this.request = arg0;
}
public void setNewsService(NewsService newsService) {
this.newsService = newsService;
}
public String list() { // 新闻列表，获取全部新闻
request.put("newslist", newsService.getAllNews());
return "list";
}
public String save() { // 存储新闻
// System.out.println(model);
newsService.saveOrupdate(model);
return "save";
}
public String post() { // 跳转到发布新闻页面
return "post";
}
@Override
public News getModel() {
// TODO Auto-generated method stub
return model;
}
@Override
public void prepare() throws Exception {
// TODO Auto-generated method stub
}
public void prepareSave() {
model = new News();
}
}四、配置struts
修改struts.xml,使用新的拦截器栈
<package name="default" namespace="/" extends="struts-default">
<!-- 定义新的拦截器,配置prepare拦截器栈的alwaysInvokePrepare参数值为false -->
<interceptors>
<interceptor-stack name="sshStack">
<interceptor-ref name="paramsPrepareParamsStack">
<param name="prepare.alwaysInvokePrepare">false</param>
</interceptor-ref>
</interceptor-stack>
</interceptors>
<!-- 使用新的拦截器栈 -->
<default-interceptor-ref name="sshStack"></default-interceptor-ref>
<action name="news-*" class="newsAction" method="{1}">
<result name="list">/WEB-INF/newslist.jsp</result>
<result name="post">/WEB-INF/newspost.jsp</result>
<result name="save" type="redirect">/news-list</result>
</action>
</package>访问news-post跳到/WEB-INF/newspost.jsp发布新闻，访问news－save存储新闻到数据库并重定向到新闻列表页。
五、编写前端页面
在index.jsp加入一行，点击中后跳转至/WEB-INF/newspost.jsp
<a href="news-post">发布新闻</a>newspost.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<s:form action="news-save" method="post">
<s:textfield name="title" label=" 新闻标题"></s:textfield>
<s:textfield name="author" label="新闻作者"></s:textfield>
<s:textfield name="source" label="新闻来源"></s:textfield>
<s:textfield name="posttime" label="发布时间"></s:textfield>
<s:textfield name="content" label="新闻内容"></s:textfield>
<s:submit value="录入"></s:submit>
</s:form>
</body>
</html>录入界面： 
新闻列表页：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE >
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>新闻列表</title>
<style type="text/css">
body {
margin: 0px;
padding: 0px;
width: 800px;
margin: 30px auto;
}
.newslist h2 {
text-align: center;
}
.newsinfo {
text-align: center;
}
.newscontent {
text-indent: 2em;
}
.newscontent a {
display: block;
float: right;
}
</style>
</head>
<body>
<s:iterator value="#request.newslist">
<div class="newslist">
<h2>${title}</h2>
<p class="newsinfo">${author}${source}${posttime}</p>
<p class="newscontent">${content}</p>
<hr>
</div>
</s:iterator>
</body>
</html>
