引入相关依赖

<!-- 提示：
     1. common-mybatis-plus:2100.8.8 中只有4个类文件，是对硬删除、硬查询的扩展支持，如果你不想引入依赖的话，你可以把这四个文件复制到自己的项目中即可
     2. common-mybatis-plus:2100.8.8 对应mybatis-plus版本3.5.4.1，扩展功能有：硬删除、硬查询
     3. common-mybatis-plus:2100.8.7 对应mybatis-plus版本3.5.2，扩展功能有：硬删除

启用增强功能

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Import;

/**
 * 导出sql注入器
 */
// 或：@ComponentScan(basePackages = "com.ideaaedi.commonmp.injector")
@Import(com.ideaaedi.commonmp.injector.MybatisPlusSqlInjector.class)
@SpringBootApplication
public class StartUp {
    public static void main(String[] args) {
        SpringApplication.run(StartUp.class, args);
    }
}

使用示例

编写mapper

import com.ideaaedi.commonmp.mapper.BaseMapperExt;
import com.ideaaedi.demo.entity.UserPO;
import org.apache.ibatis.annotations.Mapper;

@Mapper
public interface UserMapper extends BaseMapperExt<UserPO> {
}

编写service

import com.ideaaedi.commonmp.service.IServiceExt;
import com.ideaaedi.demo.entity.UserPO;

public interface UserService extends IServiceExt<UserPO> {
}

编写service-impl

import com.ideaaedi.commonmp.service.ServiceImplExt;
import com.ideaaedi.demo.entity.UserPO;
import com.ideaaedi.demo.mapper.UserMapper;
import com.ideaaedi.demo.service.UserService;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl extends ServiceImplExt<UserMapper, UserPO> implements UserService {
}
