| 本案主要功能是完成数据集的分页显示。示例代码如下： 1.PageInfo类：定义分页信息。 /******************program begin**************************/ package test; import java.io.*; public final class PaginationInfo implements Serializable { /**页大小描述每页有多少行*/ private int pageSize = 20; /**是否有上一页*/ private boolean hasPrevious; /**是否有下一页*/ private boolean hasNext; /**总行数 */ private int total; /**总页数 */ private int totalPage; /**当前页码*/ private int currentPageNumber=1; /**跳转动作：1:首页；2：前一页；3：后一页；4：末页*/ private int jumpState; public void setPageSize(int pageSize) { this.pageSize = pageSize; } public int getPageSize() { return pageSize; } public void setHasPrevious(boolean hasPrevious) { this.hasPrevious = hasPrevious; } public boolean getHasPrevious() { return hasPrevious; } public void setPreviousPageNumber(int previousPageNumber) { this.previousPageNumber = previousPageNumber; } public int getPreviousPageNumber() { return previousPageNumber; } public void setHasNext(boolean hasNext) { this.hasNext = hasNext; } public boolean getHasNext() { return hasNext; } public void setNextPageNumber(int nextPageNumber) { this.nextPageNumber = nextPageNumber; } public int getNextPageNumber() { return nextPageNumber; } public void setTotal(int total) { this.total = total; } public int getTotal() { return total; } public void setTotalPage(int totalPage) { this.totalPage=totalPage; } public int getTotalPage() { return totalPage; } public void setCurrentPageNumber(int currentPageNumber) { this.currentPageNumber=currentPageNumber; } public int getCurrentPageNumber() { return currentPageNumber; } public void setJumpState(int jumpState){ this.jumpState=jumpState; } public int getJumpState(){ return jumpState; } } |
