}(window.jQuery));

二、前端代码

1、html代码

/* 高亮显示*/
#pageLimit .active a{
    background-color: #42a5f5;
    border-color: #42a5f5;
    color:#fff;
}

<!--右侧是查询出来的文件列表 -->
        <div id="right-div">
            <ul class="law-content-con" id="showList">
            </ul>
            <!--分页组件 -->
            <div align="center">
                <ul id="pageLimit" style="padding:30px 260px;"></ul>
            </div>
        </div>

2、js文件

    init:function() {
        // 总条数
        var total;
        // 每页显示数量
        var pageSize=10;
        // 总页数
        var pages;
        // 显示页数
        var numberOfPages;
        // 关键字
        var keyName=window.localStorage.getItem("keyName");
         $.ajax({
            type: "post",
            cache: false,
            url: backbasePath+'/apia/v1/file/knowledgeList',
            dataType:"json",
            data:{// 当前的页数
                currentPageName:1,
                // 每页显示的条数
                pageSizeName:pageSize,
            },
            async: true,
            success: function(data) {
                if('000000'==data.code){
                    // 获取数据信息
                    var infoJson=data.data;
                    // 获取总共的条数
                    total=data.total;
                    pages=Math.ceil(total/pageSize);
                    if(total > 0 ){
                        if(pages < numberOfPages){
                            numberOfPages=pages;
                        }
                        // 插件的各项设置
                        var options = {

                            alignment:"center",
                            itemTexts: function (type, page, current) {
                                switch (type) {
                                    case "prev":
                                        return "上页";
                                    case "next":
                                        return "下页";
                                    case "page":
                                        return page;
                                }
                            },
                            onPageClicked: function(event, originalEvent, type, page){
                                if(page=="up" || page=="down"){
                                    return;
                                }else{
                                    $.post(backbasePath+'/apia/v1/file/knowledgeList',
                                        {
                                            currentPageName:page,
                                            // 每页显示的条数
                                            pageSizeName:pageSize,
                                        },
                                        function (map) {
                                            var infoJson = map.data;
                                            knowledgeList.show(infoJson);
                                        },
                                        "json"
                                    );
                                }
                            }
                        }
                        $('#pageLimit').bootstrapPaginator(options);
                    }
                    knowledgeList.show(infoJson);
                } else {
                    toastr.error(data.msg);
                }
            },
            error: function () {
                toastr.error('知识库检索失败！！');
            }
      });
    },

三、后端代码

  // 查询当前人所在部门上传的文件
    public String knowledgeList(HttpServletRequest req){
        String result="";
        try {
            // 封装前台参数为map
            Map<String, Object> m = getMaps(req);
            // 当前页
            int currentPage =Integer.parseInt(req.getParameter("currentPageName"));
            // 每页显示数量
            int pageSize =Integer.parseInt(req.getParameter("pageSizeName"));
            log.info("|" + m + "|");// 获取知识表中数据的个数
            int total = knowledgeDao.knowledgeCount(m);
　　　　　　　// 对应的分页方法，当前页数以及每页数量，limit
            PageHelper.startPage(currentPage, pageSize);
            List<Map<String, Object>> dataList = knowledgeDao.knowledgeList(m);
            // 获取的集合列表转换成json格式
            String dataListStr = StringTool.listToJson(dataList);
            StringBuffer sb = new StringBuffer();
            sb.append("{");
            sb.append("" + getKey("code") + ":" +  getKey(RespCode.commonSucc) + ",");
            sb.append("" + getKey("msg") + ":" + getKey(RespMsg.commonSucc) + ",");
            sb.append("" + getKey("total") + ":" + total + ",");
            // 将数据列表放在data参数里面
            sb.append("" + getKey("data") + ":" + dataListStr);
            sb.append("}");
            result = sb.toString();
        } catch (Exception e) {
            rollBack(e, log);
        }
        log.info("|" + result + "|");
        return result;
    }
