mybatis-plus 分页

一、简单，原始page方法

//分页查询
    @PostMapping ("/listPage")
    public List<User> listPage(@RequestBody QueryPageParam query){
        System.out.println(query);
        System.out.println("num==="+query.getPageNum());
        System.out.println("size==="+query.getPageSize());

        HashMap param=query.getParam();

        String userName=(String) param.get("userName");

        System.out.println("userName==="+(String) param.get("userName"));
        Page<User> page=new Page();
        page.setCurrent(query.getPageNum());
        page.setSize(query.getPageSize());

        LambdaQueryWrapper<User> lambdaQueryWrapper = new LambdaQueryWrapper();
        lambdaQueryWrapper.like(User::getUsername,userName);

        IPage result= userService.page(page,lambdaQueryWrapper);
        System.out.println("total=="+result.getTotal());


        return result.getRecords();

    }

二、自定义？？page方法

1、xxController文件

 @PostMapping ("/equipListPageC")
    public List<Equipment> equipListPageC(@RequestBody QueryPageParam query){
   
        System.out.println(query);
        System.out.
