最近要做个Springmvc +Spring+JPA+bootstrap的项目，其中分页使用
pagination.tag来做，但是不知道怎么做，还有对JPA开发也不了解。
<%@tag pageEncoding="UTF-8"%>
<%@ attribute name="page" type="org.springframework.data.domain.Page" required="true"%>
<%@ attribute name="paginationSize" type="java.lang.Integer" required="true"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%
int current = page.getNumber() + 1;
int begin = Math.max(1, current - paginationSize/2);
int end = Math.min(begin + (paginationSize - 1), page.getTotalPages());
request.setAttribute("current", current);
request.setAttribute("begin", begin);
request.setAttribute("end", end);
%>
