先看效果图：

1.后端接口

 //    查询所有商品信息
//    @CrossOrigin(origins = "*")@RequestMapping("/list1")@ResponseBodypublic List<Goodsinfo> list1(){List<Goodsinfo> list = goodsService.list();return list;}//    删除
//    @CrossOrigin(origins = "*")@RequestMapping("/del")@ResponseBodypublic String del(int id){try {goodsService.removeById(id);return "删除成功";}catch (Exception e){return "删除失败";}}//    根据条件查询@RequestMapping("/search")@ResponseBodypublic List<Goodsinfo> search(String goodsname,String goodsType){System.out.println(goodsname+","+goodsType);QueryWrapper<Goodsinfo> wrapper = new QueryWrapper<>();wrapper.like(StringUtils.isNotBlank(goodsname),"name",goodsname).like(StringUtils.isNotBlank(goodsType),"goods_type",goodsType);List<Goodsinfo> list = goodsService.list(wrapper);for (Goodsinfo goodsinfo : list) {System.out.println(goodsinfo);}return list;}// 添加数据@RequestMapping("/add")@ResponseBodypublic String add(@RequestBody Goodsinfo goodsinfo){System.out.println(goodsinfo);goodsService.save(goodsinfo);return "添加成功";}

2.前端页面：
