分页套用

先定义一个公共类用来存放4大属性+返回的泛型结果

public class PageSupport<T>{
          //页面大小
        private int pageSize=1;
        //总记录数
        private int totalCount;
        //当前页面
        private int currentPage=1;
        //页面总数
        private int totalPage;
        //查询结果
        private List<T> result;
        
    
        //返回查询结果
        public List<T> getResult() {
            return result;
        }
        
        public void setResult(List<T> result){
            this.result=result;
        }
        
        //返回页面大小
        public int getPageSize() {
            return pageSize;
        }
        //设置页面大小
        public void setPageSize(int pageSize){
              this.pageSize=pageSize;
        }
        //返回总记录数
        public int getTotalCount() {
            return totalCount;
        }
        public void setTotalCount(int totalCount) {
            this.totalCount = totalCount;
        }

        
        //返回当前页
        public int getCurrentPage() {
            return currentPage;
        }
        
        public void setCurrentPage(int currentPage) {
            this.currentPage=currentPage;
        }
        
        //返回总页面数
        public void setTotalPage(int totalPage) {
            this.totalPage=totalPage;
        }
        
        public int getTotalPage(){
            return totalPage;
        }
        
}

然后在页面的最底下插入分页的jsp

   <!-- 分页功能 -->
        <div id="fenye">
             <input type="hidden" id="currentPage" name="currentPage" value="${systemconfigPageSupport.currentPage}"/>
             <input type="hidden" id="totalPage" name="totalPage" value="${systemconfigPageSupport.totalPage}"/>    
                <ul>
             </ul>    
        </div>

下面是分页功能的样式表

/*分页*/
#fenye{
   width: 960px; 
   margin-left:auto;
   margin-right: auto;
}
#fenye ul{
   margin-top:20px;
   line-height: 28px;
   height: 28px;
   text-align: center;
}
 
#fenye ul li:first-child{
   border-top-left-radius:5px;
   border-bottom-left-radius:5px;
}

#fenye ul li:last-child{
   border-top-right-radius:5px;
   border-bottom-right-radius:5px;
   border-right: 1px solid #c4c4c4;;
}
#fenye ul li{
   border-left:1px solid #c4c4c4;
   border-bottom:1px solid #c4c4c4;
   border-top:1px solid #c4c4c4;
   background-color:#ffffff;
   width: 36px;px;
   font-size: 14px;
   list-style-type: none;
   display: inline-block;
   cursor: pointer;
 }

#fenye ul li:nth-child(1),#fenye ul li:nth-child(2),#fenye ul li:nth-last-child(1),#fenye ul li:nth-last-child(2){
    width: 50px;
}

分页的js文件

$(function(){
     var form = $("#form");
     var fenye = $("#fenye");
     //classpath的值
     var classpath = $("#classpath").val();
     //页面当前页面
     var currentPage = $("#currentPage").val();
     //页面总数
     var totalPage = $("#totalPage").val();
     //生成页面
     if(currentPage>5){
         if(parseInt(currentPage)+4>totalPage){
            /* alert("当前页大于5且当前页+4超出总页数");*/
             pageIcon(currentPage-5,totalPage);
         }else{
            /* alert("当前页大于5当前页+4小于总页数");*/
             pageIcon(currentPage-5,parseInt(currentPage)+4);
         }
     }else{  
         if(totalPage<10){
            /* alert("当前页小于5总页数小于10");*/
             
             pageIcon(1,totalPage);
         }else{
            /* alert("当前页小于总页数大于10");*/
             pageIcon(1,10);
         }
     }
     
     //根据当前选中页生成页面点击按钮
     function pageIcon(startPage,endPage){
        var    ulHtml = "<li>首页</li><li>上一页</li>";
         for(var i=startPage; i<=endPage; i++){
             ulHtml += "<li>"+i+"</li>";
         }
         ulHtml +="<li>下一页</li><li>末页</li>";
         //为当前添加样式
         $("#fenye ul").html(ulHtml);
         onClick();
     }
     //遍历li
     function onClick(){
         $("#fenye ul li").each(function(){
             if($(this).html()=="首页"){
                if(currentPage>1){
                    bindClick($(this),1);
                }else{
                     $(this).css({"color":"#c4c4c4"});
                }
             }
             if($(this).html()=="末页"){
                 if(parseInt(currentPage)<totalPage){
                     bindClick($(this),totalPage);
                 }else{
                     $(this).css({"color":"#c4c4c4"});
                 }
             }
             if($(this).html()=="上一页"){
                 if(currentPage>1){
                     bindClick($(this),parseInt(currentPage)-1);
                 }else{
                     $(this).css({"color":"#c4c4c4"});
                 }
             }
             if($(this).html()=="下一页"){
                 if(parseInt(currentPage)<totalPage){
                     bindClick($(this),parseInt(currentPage)+1);
                 }else{
                     $(this).css({"color":"#c4c4c4"});
                 }
             }
             if($(this).html()!="首页"&$(this).html()!="末页"&
                 $(this).html()!="上一页"&$(this).html()!="下一页"&
                     $(this).html()!=currentPage){
                 bindClick($(this),parseInt($(this).html()));
             }
             if($(this).html()==currentPage){
                 $(this).css({"background-color":"#efefef"});
             }
         });
     } 
     
     function bindClick(obj,value){
         obj.on("click",function(){
             $("#currentPage").val(value);
             form.attr("action",classpath+"/getSystemconfig");
             form.submit();
         });
     }
     
});

dao中添加方法

    public int getSystemconfigCount();
    /*查询全部*/
    public List<Systemconfig> getSystemconfigByAll(Map<String, Object> params);
    

service的方法

/*查询全部*/
    public PageSupport<Systemconfig> getSystemconfigByAll(int pageSize,int currentPage);

service的实现方法

public PageSupport<Systemconfig> getSystemconfigByAll(int pageSize,int currentPage){
        // TODO Auto-generated method stub
        int totalCount=0;
        int pageSize_temp=0;
        int currentPage_temp=0;
        int totalPage=0;
        //创建页面组件
        PageSupport<Systemconfig> adPageSupport=new PageSupport<Systemconfig>();
            //查询总记录
            if((totalCount=systemconfigDao.getSystemconfigCount())>0){
                //页面大小
                if(pageSize<0){
                    pageSize_temp=1;
                }else if(pageSize>10){
                    pageSize_temp=10;
                }else{
                    pageSize_temp=pageSize;
                }
                //总页面
                totalPage=(pageSize_temp+totalCount-1)/pageSize_temp;
                //当前页面
                if(currentPage<0){
                    currentPage_temp=1;
                }else if(currentPage>totalPage){
                    currentPage_temp=totalPage;
                }else{
                    currentPage_temp=currentPage;
                }
                
                //创建查询条件
                Map<String, Object> params = new HashMap<String, Object>();
                params.put("startPage", currentPage_temp==1?0:currentPage_temp*pageSize_temp-1);
                params.put("pageSize", adPageSupport.getPageSize());
                List<Systemconfig> lists=systemconfigDao.getSystemconfigByAll(params);
                
                //参数加入页面主键
                adPageSupport.setCurrentPage(currentPage_temp);
                adPageSupport.setPageSize(pageSize_temp);
                adPageSupport.setTotalCount(totalCount);
                adPageSupport.setTotalPage(totalPage);
                adPageSupport.setResult(lists);
                adPageSupport.setResult(systemconfigDao.getSystemconfigByAll(params));
            }
        return adPageSupport;
    }

action

private PageSupport<Systemconfig> systemconfigPageSupport;
    private int currentPage;
    
    
    public PageSupport<Systemconfig> getSystemconfigPageSupport() {
        return systemconfigPageSupport;
    }
    public void setSystemconfigPageSupport(
            PageSupport<Systemconfig> systemconfigPageSupport) {
        this.systemconfigPageSupport = systemconfigPageSupport;
    }
    public int getCurrentPage() {
        return currentPage;
    }
    public void setCurrentPage(int currentPage) {
        this.currentPage = currentPage;
    }

public String getSystemconfig(){
        
        systemconfigPageSupport = this.systemconfigService.getSystemconfigByAll(10, currentPage);
            ActionContext.getContext().put("systemconfigs", systemconfigPageSupport);
        return "success";
    }

struts文件这里就省略了
