实体类定义：

public class News {
	private String title;
	private String pubTime;
	private String category;
	private String newsContent;
	
	
	public String getTitle() {
	return title;
	}
	public void setTitle(String title) {
	this.title = title;
	}
	public String getPubTime() {
	return pubTime;
	}
	public void setPubTime(String pubTime) {
	this.pubTime = pubTime;
	}
	public String getCategory() {
	return category;
	}
	public void setCategory(String category) {
	this.category = category;
	}
	public String getNewsContent() {
	return newsContent;
	}
	public void setNewsContent(String newsContent) {
	this.newsContent = newsContent;
	}
}

自定义流的工具类

	out.println(strRet);
	out.flush();

	 * @return
	 */
	public List<News> getAllNews(){

业务逻辑层

public class NewsBiz {

	 * @return
	 */
	public void createAllNews() throws Exception{	
	NewsDao dao = new NewsDao();

TemplateParam类

public class TemplateParam {
	
	public static final String TITLE = "%{title}%";
	public static final String CATEGORY = "%{category}%";
	public static final String CONTENT = "%{newsContent}%";
	public static final String PUB_TIME = "%{pubTime}%";

}

用户接口层

public class NewsTest {
	
	public static void main(String[] args) {
	NewsBiz biz = new NewsBiz();
	try {
	biz.createAllNews();	
	System.out.println("新闻页面创建完毕！");
	} catch (Exception e) {
	e.printStackTrace();
