Java SSM框架实现分页

@Entity
public class Page {
private int totalRecord;// 表示查询后一共得到多少条结果记录
private int pageSize; // 表示页面一次要显示多少条记录
private int totalPage;// 表示将所有的记录进行分页后，一共有多少页
private int startIndex;// 表示从所有的结果记录中的哪一个编号开始分页查询
private int currentPage; // 表示用户想看的页数

@SuppressWarnings("unchecked")
private List list =null;// list集合是用来装载一个页面中的所有记录的

public Page(int pageNum, int totalRecord) {
this.currentPage = pageNum;
this.totalRecord = totalRecord;

this.pageSize = 5;// 设置一页默认显示10条查询记录
this.startIndex = (this.currentPage - 1) * this.pageSize;// 至于为什么this.page要减1，
// 是因为mysql数据库对于分页查询时，得到的所有的查询记录，第一条记录的编号是从0开始。
if (this.totalRecord % this.pageSize == 0) {
this.totalPage = this.totalRecord / this.pageSize;
} else {
this.totalPage = this.totalRecord / this.pageSize + 1;
}

}

//****此处省略了set和get方法****//
}

@Repository
public class PageDaoImpl implements PageDao {

@Autowired
private JdbcTemplate jdbcTemplate;

/*

int totalRecord = jdbcTemplate.queryForInt(sql, arrayParameters);
return totalRecord;
}
