对应的courseController代码

@RequestMapping("SelectKecheng")
    public String SelectKecheng(Model model,Course course, Integer pageNum, Integer pageSize) {
        if (pageNum==null || pageNum==0) {
            //当前页
            pageNum=1;
        }
        if (pageSize==null) {
            //每页的数量
            pageSize=4;
        }
        PageInfo page= courseService.queryByPage(course, pageNum, pageSize);
        model.addAttribute("page",page);
        
        return "admin-rule";    
    }

对应的courseServiceImpl.java代码

@Override
    public PageInfo queryByPage(Course course, Integer pageNum, Integer pageSize) {
        //获取当前页pageNum，pageSize条内容，开始分页
        // 第一行是设置页数和每页显示几条，插件会自动对接下来的sql语句加上分页方式。
        Page page=PageHelper.startPage(pageNum, pageSize,true);
        System.out.println("course.getName"+course.getName());
        //查询所有数据
        courseMapper.SelectKecheng(course.getName());
        //PageInfo中是分页的一些信息，包括总页数，当前页，总数据等。
        return page.toPageInfo();
    }

对应的courseMapper.java代码

List SelectKecheng(@Param("name") String name);

对应的courseMapper.xml代码

        SELECT c.*,u.id AS uid,u.name AS uname,u.classes AS uclasses,u.sorce AS usorce,u.lsorce AS ulsorce FROM `course` AS c
        JOIN `courseanduser` AS cu
        ON c.id=cu.cid
        JOIN `user` AS u
        ON cu.uid=u.id
        
            
                c.name like concat ('%',#{name},'%')
            
            and u.state=2
            ORDER BY u.sorce DESC
