pom.xml

com.baomidou mybatis-plus-boot-starter 2.3 com.baomidou mybatis-plus 2.1.0 ```

MybatisPlusConfig 

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

@EnableTransactionManagement
@Configuration
public class MybatisPlusConfig {

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

yml配置
mybatis-plus:
  mapper-locations: classpath*:mapper/*.xml
  type-aliases-package: com.scrunfast.cqsfbh.entity
  configuration:
    map-underscore-to-camel-case: true
    cache-enabled: false

以上基本就可以实现基本的什么 insertBatch,selectOne…

wrapper操作
查询用户名为张三的
EntityWrapper<User> ew = new EntityWrapper<>();
            ew.eq("name", "张三");
            User user = userService.selectOne(ew);
