涉及到的内容：
1.bootstrap-table插件；
2.mybatisplus分页查询；
3.spring封装对象匹配bootstrap-table插件格式；
4.sql查询隐藏手机号中间四位。
让我们开始：
1.想要实现bootstrap 表格服务端分页，首先需要使用插件
bootstrap-table.min.css
bootstrap-table.min.js
bootstrap-table-zh-CN.js

if (typeof parms != "undefined") {

2.mybatisplus分页
代码片段：
Page<UserInfo> page = new PageFactory<UserInfo>().defaultPage();
EntityWrapper<UserInfo> entityWrapper = new EntityWrapper<UserInfo>();
entityWrapper.setSqlSelect("user_name","insert(mobile, 4, 4, '****') as mobile","IF(status = 0,'未签到','已签到') as status","last_login_time");
entityWrapper.eq("manager_tel",managerTel);
Page<Map<String, Object>> userPages = userInfoService.selectMapsPage(page,entityWrapper);
return new PageInfoBT<>(userPages);
其中，PageFactory类是用来接收bootstrap-table传递的参数：
public class PageFactory<T> {
public Page<T> defaultPage() {
HttpServletRequest request = HttpContext.getRequest();
int limit = Integer.valueOf(request.getParameter("limit")); //每页多少条数据
int offset = Integer.valueOf(request.getParameter("offset")); //每页的偏移量(本页当前有多少条)
String sort = request.getParameter("sort"); //排序字段名称
String order = request.getParameter("order"); //asc或desc(升序或降序)
if (ToolUtil.isEmpty(sort)) {
Page<T> page = new Page<>((offset / limit + ), limit);
page.setOpenSort(false);
return page;
} else {
Page<T> page = new Page<>((offset / limit + ), limit, sort);
if (Order.ASC.getDes().equals(order)) {
page.setAsc(true);
} else {
page.setAsc(false);
}
return page;
}
}
}使用mybatisplus的好处就是可以不写sql，像这样：
EntityWrapper<UserInfo> entityWrapper = new EntityWrapper<UserInfo>();
entityWrapper.setSqlSelect("user_name","insert(mobile, 4, 4, '****') as mobile","IF(status = 0,'未签到','已签到') as status","last_login_time");
entityWrapper.eq("manager_tel",managerTel);
Page<Map<String, Object>> userPages = userInfoService.selectMapsPage(page,entityWrapper);
3.spring封装对象匹配bootstrap-table格式
PageInfoBT类用来封装对象：
public class PageInfoBT<T> {
// 结果集
private List<T> rows;
// 总数
private long total;
public PageInfoBT(Page<T> page) {
this.rows = page.getRecords();
this.total = page.getTotal();
}
public List<T> getRows() {
return rows;
}
public void setRows(List<T> rows) {
this.rows = rows;
}
public long getTotal() {
return total;
}
public void setTotal(long total) {
this.total = total;
}
}返回的数据格式：
{
"rows":[
{
"last_login_time":"2022-11-10 19:20:10",
"user_name":"王非",
"mobile":"130****2222",
"status":"已签到"
},
{
"last_login_time":"2022-11-10 19:23:44",
"user_name":"王晓晨",
"mobile":"130****3333",
"status":"已签到"
}
],
"total":""
}4.sql查询隐藏手机号中间四位：
SELECT
username,
insert(mobile, , , '****'),
IF(status = ,'未签到','已签到') as status,
time
FROM
user
