分页插件使用:

struts.xml的配置

<package name="name" extends="struts-default,json-default">

<action name="limit" class="com.nxdcms.limitpage.LimitAction">

<result name="success" type="json">

<param name="root">result</param>//返回的变量名

</result>

</action>

</package>

jsp中ajax：

$.ajax({

type:"get",//get/post

url:"limit.action",

dataType:"json",

data:{//传到后台的参数

"pageSize":pageSize,

"curPage":curPage,

"grade":grade,

"teacher":teacher,

"time":time},

success:function(data){//得到后台返回后要做的事情

var json = data.list;

$("#mytable .tr").remove();

for (var i=0;i<json.length;i++) {

$("#mytable").append($("<tr class='tr'><td>"+json[i].subcompid+"</td><td>"+json[i].awardGrade+"</td><td>"+json[i].awardName+"</td><td>"+json[i].teacher+"</td><td><a href='content.action?Subcompid="+json[i].subcompid+"'>"+"详情"+"</a></td></tr>"));

}

},

error:function(XMLHttpRequest, textStatus, errorThrown){

alert("error");

}

});

后台：

private String pageSize ;

private String curPage ;

private String grade ;

private String teacher ;

private String time ;

private PageObject result = null;

public String execute() throws Exception {

//调试使用

System.out.println("当前页"+curPage+"每页行数"+pageSize+grade+teacher+time);

//定义查询条件

Criterion criterion0=null,criterion1=null,criterion2=null;

//创建hibernate的session

Session session = HibernateUtils1.getSession();

//定义hibernate所要查询类

Class ObjClass = null;

try {

//实例化要查询的类名

ObjClass = Class.forName("com.nxdcms.entity.Subcompetition");

} catch (ClassNotFoundException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

//过滤查询条件，没有查询条件就将空值传入方法

if(grade!=null&&!"".equals(grade)&&!"null".equals(grade)){

criterion0 = Restrictions.like("awardGrade", grade);

}else{

System.out.println("grade null");

}

if(teacher!=null&&!"".equals(teacher)&&!"null".equals(teacher)){

criterion1 = Restrictions.like("teacher",teacher);

}else{

System.out.println("teacher null");

}

if(time!=null&&!"".equals(time)&&!"null".equals(time)){

criterion2 = Restrictions.like("awarddate", time);

}else{

System.out.println("time null");

}

//定义排序（降序/升序）

Order order = Order.asc("stuId1");

//参数传入工具，返回一个具体的分页类

//注意最后三个查询条件可以不止三个，理论可以传入无限多个查询条件

result = LimitDao.queryByPage(session, Integer.parseInt(pageSize), Integer.parseInt(curPage), ObjClass, order,

criterion0, criterion1, criterion2);

//调试使用

if (result == null) {

System.out.println("po null");

} else {

for (Object o : result.getList()) {

Subcompetition s = (Subcompetition) o;

System.out.println(s.getAwardGrade());

}

}

System.out.println(result);

return "success";

}
