1. Maven依赖

     <!-- mybatis-plus -->
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.1.2</version>
        </dependency>

 2. 注解

  A. @MapperScan:指定要扫描的mapper类包的路径,加在启动类上;

3. application.yml配置文件

mybatis-plus:
    global-config:
        db-config:
       # 全局主键类型
            id-type: auto
    configuration:
     # 是否开启下划线转驼峰规则映射
        map-underscore-to-camel-case: true
  # mapper xml配置文件路径
    mapper-locations: classpath*:mapper/*.xml
  # 直接使用类名,而非全限定类名
    type-aliases-package: ${application.base-package}.entity

 4. 插件分页配置类

package com.ruhuanxingyun.fastdfs.config;

import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @description: MybatisPlus 配置类
 * @author: ruphie
 * @date: Create in 2020/12/20 9:48
 * @company: ruhuanxingyun
 */
@Configuration
public class MybatisPlusConfig {

    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }

}
