This article will introduce to you two ways to implement bootstrap table paging. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

A brief discussion on two ways to implement bootstrap table paging

Two ways of bootstrap table paging:

Front-end paging: Query all data from the database at one time and perform it on the front-end Paging (front-end paging can be used when the amount of data is small or the logic processing is not complex)

Server paging: only query the pieces of data required for loading the current page each time

bootstrap download address ：http://www.bootcss.com/

bootstrap-table Download address: http://bootstrap-table.wenzhixin.net.cn/

jquery Download address: http:/ /www.jq22.com/jquery-info122

Paging effect (please ignore the style)

1: Prepare js, css and other files

Put the downloaded document directly into the webapp directory

Introduce the required js and css into the page

<!-- 引入的css文件  -->
<link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" />
<link href="bootstrap-table/dist/bootstrap-table.min.css"
	rel="stylesheet">
<!-- 引入的js文件 -->
<script src="jquery/jquery.min.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>
<script src="bootstrap-table/dist/bootstrap-table.min.js"></script>
<script src="bootstrap-table/dist/locale/bootstrap-table-zh-CN.min.js"></script>

2: HTML page tag content

<div class="panel panel-default">
    <div class="panel-heading">
        查询条件
    </div>
    <div class="panel-body form-group" style="margin-bottom:0px;">
        <label class="col-sm-1 control-label" style="text-align: right; margin-top:5px">姓名：</label>
        <div class="col-sm-2">
            <input type="text" class="form-control" name="Name" id="search_name"/>
        </div>
        <label class="col-sm-1 control-label" style="text-align: right; margin-top:5px">手机号：</label>
        <div class="col-sm-2">
            <input type="text" class="form-control" name="Name" id="search_tel"/>
        </div>
        <div class="col-sm-1 col-sm-offset-4">
            <button class="btn btn-primary" id="search_btn">查询</button>
        </div>
     </div>
</div>
<table id="mytab" class="table table-hover"></table>

3: JS paging code

$(&#39;#mytab&#39;).bootstrapTable({
	method : &#39;get&#39;,
	url : "user/getUserListPage",//请求路径
	striped : true, //是否显示行间隔色
	pageNumber : 1, //初始化加载第一页
	pagination : true,//是否分页
	sidePagination : &#39;client&#39;,//server:服务器端分页|client：前端分页
	pageSize : 4,//单页记录数
	pageList : [ 5, 10, 20, 30 ],//可选择单页记录数
	showRefresh : true,//刷新按钮
	queryParams : function(params) {//上传服务器的参数
		var temp = {//如果是在服务器端实现分页，limit、offset这两个参数是必须的
			limit : params.limit, // 每页显示数量
			offset : params.offset, // SQL语句起始索引
			//page : (params.offset / params.limit) + 1, //当前页码 
 
			Name : $(&#39;#search_name&#39;).val(),
			Tel : $(&#39;#search_tel&#39;).val()
		};
		return temp;
	},
	columns : [ {
		title : &#39;登录名&#39;,
		field : &#39;loginName&#39;,
		sortable : true
	}, {
		title : &#39;姓名&#39;,
		field : &#39;name&#39;,
		sortable : true
	}, {
		title : &#39;手机号&#39;,
		field : &#39;tel&#39;,
	}, {
		title : &#39;性别&#39;,
		field : &#39;sex&#39;,
		formatter : formatSex,//对返回的数据进行处理再显示
	}, {
		title : &#39;操作&#39;,
		field : &#39;id&#39;,
		formatter : operation,//对资源进行操作
	} ]
})
 
//value代表该列的值，row代表当前对象
function formatSex(value, row, index) {
	return value == 1 ? "男" : "女";
	//或者 return row.sex == 1 ? "男" : "女";
}
 
//删除、编辑操作
function operation(value, row, index) {
	var htm = "<button>删除</button><button>修改</button>"
	return htm;
}
 
//查询按钮事件
$(&#39;#search_btn&#39;).click(function() {
	$(&#39;#mytab&#39;).bootstrapTable(&#39;refresh&#39;, {
		url : &#39;user/getUserListPage&#39;
	});
})

Four: bootstrap-table implements front-end paging

Modify some attributes in the JS paging code

sidePagination:&#39;client&#39;,
queryParams : function (params) {
        var temp = {
            name:$(&#39;#search_name&#39;).val(),
            tel:$(&#39;#search_tel&#39;).val()
        };
        return temp;
    },

Define user object

package com.debo.common;
 
public class User {
	
	private Integer id;
	private String loginName;
	private String name;
	private String tel;
	private Integer sex;
	
        //省略Get/Set函数
}

Server Controller layer code

/**
*直接一次性查出所有的数据,返回给前端，bootstrap-table自行分页
*/
@RequestMapping("/getUserListPage")
@ResponseBody
public List<User> getUserListPage(User user,HttpServletRequest request){
	List<User> list = userService.getUserListPage(user);
	return list;
}

mabatis statement

<select id="getUserListPage" resultType="com.debo.common.User">
	SELECT * FROM user WHERE 1 = 1
	<if test="name!=null and name !=&#39;&#39;">
		AND name LIKE CONCAT(&#39;%&#39;,#{name},&#39;%&#39;)
	</if>
	<if test="tel!=null and tel !=&#39;&#39;">
		AND tel = #{tel}
	</if>
</select>

5: bootstrap-table implements server-side paging

Set certain attributes in the JS paging code 

sidePagination:&#39;server&#39;,
queryParams : function (params) {
    var temp = {
        limit : params.limit, // 每页显示数量
        offset : params.offset, // SQL语句起始索引
        page: (params.offset / params.limit) + 1,   //当前页码
            
        Name:$(&#39;#search_name&#39;).val(),
        Tel:$(&#39;#search_tel&#39;).val()
    };
    return temp;
},

Encapsulate the public page object and let the user object inherit the page object

package com.debo.common;
 
public class Page {
	//每页显示数量
	private int limit;
	//页码
	private int page;
	//sql语句起始索引
	private int offset;
	public int getLimit() {
		return limit;
	}
	public void setLimit(int limit) {
		this.limit = limit;
	}
	public int getPage() {
		return page;
	}
	public void setPage(int page) {
		this.page = page;
	}
	public int getOffset() {
		return offset;
	}
	public void setOffset(int offset) {
		this.offset = offset;
	}
 
}
package com.debo.common;
 
public class User extends Page{
	
	private Integer id;
	private String loginName;
	private String name;
	private String tel;
	private Integer sex;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getLoginName() {
		return loginName;
	}
	public void setLoginName(String loginName) {
		this.loginName = loginName;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getTel() {
		return tel;
	}
	public void setTel(String tel) {
		this.tel = tel;
	}
	public Integer getSex() {
		return sex;
	}
	public void setSex(Integer sex) {
		this.sex = sex;
	}
}

Encapsulate the returned data entity class

package com.debo.common;
 
import java.util.ArrayList;
import java.util.List;
 
public class PageHelper<T> {
    //实体类集合
    private List<T> rows = new ArrayList<T>();
    //数据总条数
    private int total;
 
    public PageHelper() {
        super();
    }
 
    public List<T> getRows() {
        return rows;
    }
 
    public void setRows(List<T> rows) {
        this.rows = rows;
    }
 
    public int getTotal() {
        return total;
    }
 
    public void setTotal(int total) {
        this.total = total;
    }
 
}

Server Controller layer code

@RequestMapping("/getUserListPage")
@ResponseBody
public PageHelper<User> getUserListPage(User user,HttpServletRequest request) {
		
        PageHelper<User> pageHelper = new PageHelper<User>();
	// 统计总记录数
	Integer total = userService.getTotal(user);
	pageHelper.setTotal(total);
 
	// 查询当前页实体对象
	List<User> list = userService.getUserListPage(user);
	pageHelper.setRows(list);
 
	return pageHelper;
}

mybatis statement

<select id="getTotal" resultType="int">
	SELECT count(1) FROM user WHERE 1 = 1
	<if test="name!=null and name !=&#39;&#39;">
		AND name LIKE CONCAT(&#39;%&#39;,#{name},&#39;%&#39;)
	</if>
	<if test="tel!=null and tel !=&#39;&#39;">
		AND tel = #{tel}
	</if>
</select>
 
<select id="getUserListPage" resultType="com.debo.common.User">
	SELECT * FROM user WHERE 1 = 1
	<if test="name!=null and name !=&#39;&#39;">
		AND name LIKE CONCAT(&#39;%&#39;,#{name},&#39;%&#39;)
	</if>
	<if test="tel!=null and tel !=&#39;&#39;">
		AND tel = #{tel}
	</if>
	LIMIT #{offset},#{limit}
</select>

tip: Reload the table after adding, deleting, or modifying operations

$("#mytab").bootstrapTable(&#39;refresh&#39;, {url : url});
