运行：

或者

然后补齐service层和controller层

package com.demo_mybatis.controller;

import com.demo_mybatis.model.ProductInfo;
import com.demo_mybatis.service.ProductInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class ProductInfoController {
    @Autowired
    private ProductInfoService productInfoService;

    @ResponseBody
    @PostMapping(value = "/addProductInfo")
    public int addProductInfo(ProductInfo productInfo){
        /*ProductInfo productInfo = new ProductInfo();
        productInfo.setProductId("1");
        productInfo.setProductName("张亮麻辣烫20元套餐");
        productInfo.setProductPrice(20.00);
        productInfo.setProductStock(20);
        productInfo.setProductDescription("张亮麻辣烫20元套餐张亮麻辣烫20元套餐张亮麻辣烫20元套餐张亮麻辣烫20元套餐张亮麻辣烫20元套餐张亮麻辣烫20元套餐张亮麻辣烫20元套餐");
        productInfo.setProoductIcon("1111");
        productInfo.setCategoryType(1);*/
        return productInfoService.insert(productInfo);
    }
}

package com.demo_mybatis.service.impl;

import com.demo_mybatis.mapper.ProductInfoMapper;
import com.demo_mybatis.model.ProductInfo;
import com.demo_mybatis.service.ProductInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class ProductInfoServiceImpl implements ProductInfoService {
    @Autowired
    private ProductInfoMapper productInfoMapper;
    @Override
    public int insert(ProductInfo record) {
        return productInfoMapper.insert(record);
    }

    @Override
    public int insertSelective(ProductInfo record) {
        return 0;
    }
}

package com.demo_mybatis.service;

import com.demo_mybatis.model.ProductInfo;

public interface ProductInfoService {
    int insert(ProductInfo record);

    int insertSelective(ProductInfo record);
}

运行：
