首先是dataobject，项目是用的是SpringMVC
public class MbChannelExtensionDO {
private static final long serialVersionUID = 741231858441822688L;
//========== properties ==========

}

public void setGmtCreate(Date gmtCreate) {

public void setStatus(String status) {

}接着是使用分页的Page类
public class PageDO {
/**
* 总条数
*/
private int totalNumber;
/**
* 当前第几页
*/
private int currentPage;
/**
* 总页数
*/
private int totalPage;
/**
* 每页显示条数
*/
private int pageNumber = 10;
/**
* 依据当前对象中属性值计算并设置相关属性值
*/
public void count() {
// 计算总页数
int totalPageTemp = this.totalNumber / this.pageNumber;
int plus = (this.totalNumber % this.pageNumber) == 0 ? 0 : 1;
totalPageTemp = totalPageTemp + plus;
if(totalPageTemp <= 0) {
totalPageTemp = 1;
}
this.totalPage = totalPageTemp;
// 设置当前页数
// 总页数小于当前页数，应将当前页数设置为总页数
if(this.totalPage < this.currentPage) {
this.currentPage = this.totalPage;
}
// 当前页数小于1设置为1
if(this.currentPage < 1) {
this.currentPage = 1;
}
}
public int getTotalNumber() {
return totalNumber;
}
public void setTotalNumber(int totalNumber) {
this.totalNumber = totalNumber;
this.count();
}
public int getCurrentPage() {
return currentPage;
}
public void setCurrentPage(int currentPage) {
this.currentPage = currentPage;
}
public int getTotalPage() {
return totalPage;
}
public void setTotalPage(int totalPage) {
this.totalPage = totalPage;
}
public int getPageNumber() {
return pageNumber;
}
public void setPageNumber(int pageNumber) {
this.pageNumber = pageNumber;
this.count();
}
}
DAO层实现分页的两个方法
/**
* select <tt>MbChannelExtensionDO</tt> object by page to DB table <tt>MB_CHANNEL_EXTENSION</tt>, return primary key
*
* <p>
* The sql statement for this operation is <br>
* <tt>select * from MB_CHANNEL_EXTENSION where id not in(select id from MB_CHANNEL_EXTENSION
* where rownum<=(PAGESIZE*(CURRENTPAGE-1))) and rownum<=PAGESIZE order by id; </tt>
*
* @param page,mbChannelExtension
* @return List<MbChannelExtensionDO>
* @throws DataAccessException
*/
@Override
public List<MbChannelExtensionDO> getMbChannelExtensionByPage(MbChannelExtensionDO mbChannelExtensionDO,PageDO page) throws DataAccessException {
if (page == null) {
throw new IllegalArgumentException("Can't select by a null page.");
}
Map map=new HashMap();
map.put("page",page);
map.put("mbChannelExtension",mbChannelExtensionDO);
return getSqlMapClientTemplate().queryForList("MS-MB-CHANNEL-EXTENSION-SELECT-BY-PAGE", map);
}
@Override
public int countOfMbChannelExtension(MbChannelExtensionDO mbChannelExtensionDO ) throws DataAccessException {
int count=(Integer)getSqlMapClientTemplate().queryForObject("MS-MB-CHANNEL-EXTENSION-COUNT",mbChannelExtensionDO);
return count;
}

page.count();
