Introduction to ssm paging method (code example)

This article brings you an introduction to the ssm paging method (code example). It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The page is implemented with bootstrapTable (just configure the query parameters). The prerequisite is to introduce the css of bootstrapTable and js

function load() {
    var typeid = $("#typeid").val();
    $('#exampleTable').bootstrapTable({
                        method : 'get', // 服务器数据的请求方式 get or post
                        url : "xxx/base/supSupt/list", // 服务器数据的加载地址
                        iconSize : 'outline',
                        toolbar : '#exampleToolbar',
                        striped : true, // 设置为true会有隔行变色效果
                        dataType : "json", // 服务器返回的数据类型
                        pagination : true, // 设置为true会在底部显示分页条
                        singleSelect : false, // 设置为true将禁止多选
                        pageSize : 10, // 如果设置了分页，每页数据条数
                        pageNumber : 1, // 如果设置了分布，首页页码
                        search : true, // 是否显示搜索框，给参数就可以搜索了
                        showColumns : false, // 是否显示内容下拉框（选择显示的列）
                        clickToSelect:true,
                        sortOrder: "desc",
                        sidePagination : "server", // 设置在哪里进行分页，可选值为"client" 或者
                        queryParams : function(params) {//后台有个Query类，只要添加了键值对而且是表中有的他会自动弄进去

                            return {
                                // 说明：传入后台的参数包括offset开始索引，limit步长，sort排序列，order：desc或者,以及所有列的键值对
                                limit : params.limit,
                                offset : params.offset,
sort:"createdat",根据创建时间（对应映射文件的条件）
                                                    order:"desc",排序
                                type:typeid
                            };
                        },
                        columns : [
                                {
                                    checkbox : true
                                },
                                {
                                    field : 'code',
                                    title : '编码'
                                                    },
                                {
                                    field : 'comp',
                                    title : '公司名'
                                },
                                {
                                    field : 'busilicence',
                                    title : '信用代码'
                                },
                                {
                                    field : 'law',
                                    title : '法定代表人'
                                },
                                {
                                    field : 'tel',
                                    title : '联系电话'
                                }]
    })
}

2. Controller

@ResponseBody
    @GetMapping("/list")
    @RequiresPermissions("base:supSupt:add")
    public PageUtils list(@RequestParam Map<String, Object> params){
        //查询列表数据
        Query query = new Query(params);
        List<SupSuptSupVO> supSuptList = supSuptService.getSupListExcludeSuptpyeId(query);
        int total = supSuptService.getSupListCountExcludeSuptpyeId(query);
        PageUtils pageUtils = new PageUtils(supSuptList, total);
        return pageUtils;
    }

1. Tool class
   Tool class for paging
2. mybatis mapping file

<select id="getSupListExcludeSuptpyeId" resultType="com.xxx.bid.base.vo.SupSuptVO">
        select * from bid_sup where id not in (
            select ss.supid from bid_sup_supt as ss inner join bid_sup as s on ss.supid = s.id
            <where>
                <if test="typeid != null and typeid != &#39;&#39;"> and ss.typeid = #{typeid} </if>
            </where>
        ) 
            <choose>
            <when test="sort != null and sort.trim() != &#39;&#39;">
                order by ${sort} ${order}
            </when>
            <otherwise>
                order by ls desc
            </otherwise>
        </choose>
        <if test="offset != null and limit != null">
            limit #{offset}, #{limit}
        </if>
    </select>
    <select id="getSupListCountExcludeSuptpyeId" resultType="int">
        select count(*) from bid_sup where id not in (
            select ss.supid from bid_sup_supt as ss inner join bid_sup as s on ss.supid = s.id
            <where>
                <if test="typeid != null and typeid != &#39;&#39;"> and ss.typeid = #{typeid} </if>
            </where>
        )
    </select>
