添加配置

配置application.yml

mybatis-plus:
  mapper-locations: classpath*:mapper/**.xml
  #实体扫描，多个package用逗号或者分号分隔
  #  typeAliasesPackage: com.pm.facade.*.entity
  #  typeEnumsPackage: com.baomidou.springboot.db.entity.enums
  global-config:
    db-config:
      #主键类型  0:"数据库ID自增", 1:"用户输入ID",2:"全局唯一ID (数字类型唯一ID)", 3:"全局唯一ID UUID";
      id-type: AUTO
      #字段策略 0:"忽略判断",1:"非 NULL 判断"),2:"非空判断"
      field-strategy: not_empty
      #驼峰下划线转换
      column-underline: true
      #数据库大写下划线转换
      #capital-mode: true
      #逻辑删除配置
      logic-delete-value: Y
      logic-not-delete-value: N
      db-type: mysql
      #刷新mapper 调试神器
    refresh: true
      #自定义填充策略接口实现
      #meta-object-handler: com.baomidou.springboot.xxx
    #自定义SQL注入器
  #sql-injector: com.baomidou.springboot.xxx
  configuration:
    map-underscore-to-camel-case: true
    cache-enabled: false

pagehelper:
  reasonable: true # 禁用合理化时
  support-methods-arguments: true
  params: count=countSql
  row-bounds-with-count: true
  helper-dialect: mysql

启动类上配置

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

//扫包地址
@MapperScan(basePackages = "com.puhua.platform.dao")
@SpringBootApplication
public class PlatformApplication {
    
    

    public static void main(String[] args) {
    
    
        SpringApplication.run(PlatformApplication.class, args);
    }

}

建议

使用mybais-plus建议使用mybatis-plus-generator逆向工程生成对应的mapper和实体类
