easyuidatagrid分页

1.定义分页基类PaginatedHelper，绑定和读取分页信息

packagemons.web.util;

importjava.io.Serializable;

publicclassPaginatedHelperimplementsSerializable{

//每页记录条数

/**

*

*/

privatestaticfinallongserialVersionUID=1L;

privateintpage=1;

privateintrows;

//开始位置

privateintstartIndex;

publicstaticfinalintPAGE_SIZE=15;

/**

*获取当前页

*@return

*/

publicintgetCurrentPage（）{

returnpage;

}

publicvoidsetPage（intpage）{

this.page=page;

}

publicvoidsetRows（introws）{

if（rows>0）{

this.rows=rows;

}else{

this.rows=PAGE_SIZE;

}

}

//计算查询开始位置

privatevoidcalculatestartIndex（）{

if（this.page>0）{

}else{

page=1;

}

this.startIndex=（this.page-1）*this.rows;

}

/**

*取得开始位置

*@return

*/

publicintgetStartIndex（）{

calculatestartIndex（）;

returnstartIndex;

}

publicintgetPageSize（）{

returnthis.rows;

}

publicintgetRows（）{

returnrows;

}

}

2.定义查询信息类，继承基类

上图中的红圈信息为查询信息，及一些业务逻辑信息都包含进去。

packagemon.dto;

importjava.util.List;

importmon.util.PaginatedHelper;

publicclassPaginateextendsPaginatedHelper{

privatestaticfinallongserialVersionUID=1L;

privateStringapplyDateStart;

privateStringapplyDateEnd;

privateDepartmentInfodepartmentCode;

privateBranchInfobranchCode;

privateStringbusinessSeries;

publicStringgetApplyDateStart（）{

returnapplyDateStart;

}

publicvoidsetApplyDateStart（StringapplyDateStart）{

this.applyDateStart=applyDateStart;

}

publicStringgetApplyDateEnd（）{

returnapplyDateEnd;

}

publicvoidsetApplyDateEnd（StringapplyDateEnd）{

this.applyDateEnd=applyDateEnd;

}

publicDepartmentInfogetDepartmentCode（）{

returndepartmentCode;

}

publicvoidsetDepartmentCode（DepartmentInfodepartmentCode）{

this.departmentCode=departmentCode;

}

publicBranchInfogetBranchCode（）{

returnbranchCode;

}

publicvoidsetBranchCode（BranchInfobranchCode）{

this.branchCode=branchCode;

}

publicStringgetBusinessSeries（）{

returnbusinessSeries;

}

publicvoidsetBusinessSeries（StringbusinessSeries）{

this.businessSeries=businessSeries;

}

Listlist;

publicListgetList（）{

returnlist;

}

publicvoidsetList（Listlist）{

this.list=list;

}

}

3.前台页面:

<%@pagelanguage="java"contentType="text/html;charset=utf-8"

pageEncoding="utf-8"%>

<%@includefile="/WEB-INF/views/commons/head.jsp"%>

formmodelAttribute="voucherFitting"method="post"name="form1"id="form1">
