mybatisplus(service CRUD 接口)

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

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