Mapper：
分页查询意向客户
@Select("SELECT * FROM t_customer WHERE intention = 1 and periods = #{arg0} LIMIT #{arg1},#{arg2}")
publicList getIntentionByPage(String periods,intstart,intsize);
Service：
publicList getIntentionByPage(String periods,intstart,intsize)
{
returncustomerMapper.getIntentionByPage(periods,start,size);
}
Controller：
@RequestMapping("/customerIntentionByPage")
publicList getIntentionByPage(Page page )
{
page.initNum();
returncustomerService.getIntentionByPage(page.getPeriods(),page.getStart(),page.getSize());
}
封装的Page：
public classPage
{
private intsize;
private intpageNum;
privateStringperiods;
private intstart;
private intend;
private intcount;
public intgetCount()
{
returncount;
}
public voidsetCount(intcount)
{
this.count= count;
}
public intgetSize()
{
returnsize;
}
public voidsetSize(intsize)
{
this.size= size;
}
public intgetPageNum()
{
returnpageNum;
}
public voidsetPageNum(intpageNum)
{
this.pageNum= pageNum;
}
publicString getPeriods()
{
returnperiods;
}
public voidsetPeriods(String periods)
{
this.periods= periods;
}
public intgetStart()
{
returnstart;
}
public voidsetStart(intstart)
{
this.start= start;
}
public intgetEnd()
{
returnend;
}
public voidsetEnd(intend)
{
this.end= end;
}
public voidinitNum()
{
if(pageNum>=1&&size>0)
{
//从第几条开始
start= ((pageNum-1) *size) ;
//在第几条结束
end= ((pageNum-1) *size) +size;
}
}
}
在浏览器中输入地址/periods=?&pageNum
=?&size=?
参数意思是：第几期，第几页，每一页显示几条数据
