Java+Jsp+Struts.tag完整分页（实战样例）

实体类（feeds）：主要字段

private int pageIndex;
	private int maxIndex;

后台分页代码：

List list = new ArrayList();
// 设置分页默认页码(控制上一页不越值)
		if (feeds.getPageIndex() <= 1) {
			feeds.setPageIndex(1);
		}

		// 组合查询语句（必须有一个查询条件，分页条件为页码）
		String querySql = "select username,snp(content,\""
				+ feeds.getContent()
				+ "\",\"span style='color:red'\"),`datetime`,website,is_original,reposts_num,"
				+ "comments_num,score " + "from feeds where content=\""
				+ feeds.getContent() + "\" " + condition + " limit "
				+ ((feeds.getPageIndex() - 1) * 10 + 1) + ","
				+ (feeds.getPageIndex() * 10) + ";";
		// eql执行步骤并获取数据
		Eql eql = new Eql();
		eql.connect();
		eql.select_db();
		list = eql.query(querySql);
		if (list.size() > 0) {
			int total = Integer
					.parseInt(((List) list.get(0)).get(0).toString());
			feeds.setMaxIndex(total % 10 == 0 ? total / 10 : total / 10 + 1);
		}

		return list;

private INewsService newsService;
	private List list;
	private WeiboFeeds feeds = new WeiboFeeds();

public String execute() {
		list = newsService.retrieve(feeds);
		return SUCCESS;
