Javaでページネーションする方法

public class Page { private long totalCount = 0;// 总记录数 private int pageNumber = 1;// 当前页号，默认显示第一页 private int pageSize = 20; // 每页大小，默认每页20条 private int totalPage = 0;// 总页数，默认为0 private int startRow = 0;// 起始记录行号，默认为从表头开始 /** * 分页计算方法，由setTotalCount调用 */ public void pagination() { // 计算总页数 if (this.totalCount % pageSize == 0) this.totalPage = new Long(this.totalCount / pageSize).intValue(); else this.totalPage = new Long(this.totalCount / pageSize).intValue() + 1; // 排除错误页号 if (this.pageNumber < 1) this.pageNumber = 1; if (this.pageNumber > this.totalPage) this.pageNumber = this.totalPage; // 计算起始行号 this.startRow = (this.pageNumber - 1) * this.pageSize; } public long getTotalCount() { return totalCount; } public void setTotalCount(long totalCount) { this.totalCount = totalCount; this.pagination(); } public int getPageNumber() { return pageNumber; } public void setPageNumber(int pageNumber) { this.pageNumber = pageNumber; } public int getPageSize() { return pageSize; } public void setPageSize(int pageSize) { this.pageSize = pageSize; } public int getTotalPage() { return totalPage; } public void setTotalPage(int totalPage) { this.totalPage = totalPage; } public int getStartRow() { return startRow; } public void setStartRow(int startRow) { this.startRow = startRow; } }
