先看效果图：
1.后端接口
// 查询所有商品信息
// @CrossOrigin(origins = "*")
@RequestMapping("/list1")
@ResponseBody
public List<Goodsinfo> list1(){
List<Goodsinfo> list = goodsService.list();
return list;
}
// 删除
// @CrossOrigin(origins = "*")
@RequestMapping("/del")
@ResponseBody
public 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")
@ResponseBody
public 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")
@ResponseBody
public String add(@RequestBody Goodsinfo goodsinfo){
System.out.println(goodsinfo);
goodsService.save(goodsinfo);
return "添加成功";
