以下是首页跳转的struts2的那个Action
package com.news.struts2.action;
import java.util.List;
import org.apache.struts2.ServletActionContext;
import com.news.dao.news.NewsDao;
import com.news.entity.news.Newstb;
import com.news.splitpage.SplitPage;
import com.opensymphony.xwork2.ActionSupport;
public class IndexAction extends ActionSupport {
private NewsDao newsDao;
public void setNewsDao(NewsDao newsDao) {
this.newsDao = newsDao;
}
@Override
public String execute() throws Exception {
SplitPage sp = newsDao.splitpage(0,10);
List<Newstb> lst = (List<Newstb>) sp.getLst();
ServletActionContext.getContext().put("newlist",lst);
return SUCCESS;
}
}

private List<Newstb> news;
public List<Newstb> getNews() {return news;}
public void setNews(List<Newstb> news) {this.news = news;}
public int getId() {return id;}
public void setId(int id) {this.id = id; }
public String getName() { return name;}
public void setName(String name) {this.name = name;}
}
