一、在pom.xml配置依赖

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.1</version>
        </dependency>

二、在application.yml里配置xml 位置

# 配置mapper xml的位置
mybatis:
  mapper-locations: classpath*:mapper/*.xml

三、新建MyBatisPlusPageConfig配置mybatisplus翻页

import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**

@Configuration
@ConditionalOnClass(value = {PaginationInterceptor.class})
public class MyBatisPlusPageConfig {
    @Bean
    public PaginationInterceptor paginationInterceptor() {
        return new PaginationInterceptor();
    }
}
