基于bootstrap + velocity的分页实现

PageBean.java代码

public class PageBean {
	private int total;
	private int totalPage;
	private int pageNum;
	private int start;
	private int offset = 4;
	private List<Integer> pages = new ArrayList<Integer>();
	
	private int pre;
	private int next;

	public static final int SIZE = 5;
	
	public PageBean(int pageNum,int total) {
		this.pageNum = pageNum;
		this.total = total;
		
		getTotalPage();
		getStart();
		getPages();
		getPre();
		getNext();
	}

	public int getTotal() {
		return total;
	}

	public void setTotal(int total) {
		this.total = total;
	}

	public int getTotalPage() {
		if(total%sIZE==0) {
			totalPage = total/SIZE;
		} else {
			totalPage = total/SIZE + 1;
		}
		return totalPage;
	}

		int totalPage = 0;
		if(total%size==0) {
			totalPage = total/size;
		} else {
			totalPage = total/size + 1;
		}
		return totalPage;
	}

	public int getPageNum() {
		return pageNum;
	}

	public void setPageNum(int pageNum) {
		this.pageNum = pageNum;
	}
	
	public int getStart() {
		start = (pageNum-1) * SIZE;
		return start;
	}

	public int getoffset() {
