一、我们在控制器层都是调用Service层，不会直接调用仓储层。现在我给大家介绍一下怎么快速实现Service 的CRUD

定义接口：IProductService 继承IService<实体>

package com.saas.plusdemo;import com.baomidou.mybatisplus.extension.service.IService;public interface IProductService extends IService<Product> {}

添加实现类：ProductServiceImpl 继承ServiceImpl<Map仓储,实体>

package com.saas.plusdemo;import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.saas.plusdemo.mapper.IProductRepository;
import org.springframework.stereotype.Service;@Service
public class ProductServiceImpl extends ServiceImpl<IProductRepository,Product>  implements IProductService{}

二、添加单元测试

    @Testvoid serviceAdd(@Autowired IProductService productService) {Product product=new Product();product.setId(UUID.randomUUID().toString());product.setName("hi service");productService.save(product);}
