引入依赖：

  　　
   com.baomidou
   mybatis-plus-boot-starter

   mysql
   mysql-connector-java

在application.yml配置

spring:

 url: jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=UTF-8

新建一个配置类

@Configuration
public class MybatisPlusConfig {
    @Bean//加入Spring容器中
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor mybatisPlusInterceptor = new MybatisPlusInterceptor();
        mybatisPlusInterceptor.addInnerInterceptor(new PaginationInnerInterceptor());
        return mybatisPlusInterceptor;
    }
}

 public Rpage(int page,int pageSize){
        Page page1=new Page(page,pageSize);
        LambdaQueryWrapper queryWrapper=new LambdaQueryWrapper<>();
        queryWrapper.orderByAsc(Category::getCreateTime);
        categoryService.page(page1,queryWrapper);
        return R.success(page1);
