2, the configuration file application.yml

Note  pagehelper is a root and spring at the same level

      suffix: .jsp
  datasource:
    url: jdbc:mysql://localhost:3306/myrec?characterEncoding=utf8&useSSL=true
    username: root
    password: m123456
    driver-class-name: com.mysql.jdbc.Driver
       
#配置分页插件pagehelper
pagehelper:
    helperDialect: mysql
    reasonable: true
    supportMethodsArguments: true
    params: count=countSql

     * 按分页查询
     */
    @Override
    public PageResult findPage(int pageNum, int pageSize) {
        PageHelper.startPage(pageNum, pageSize);
        Page<Loginuser> page=   (Page<Loginuser>) loginuserMapper.selectByExample(null);
        return new PageResult(page.getTotal(), page.getResult());
    }
