存在问题的代码

 //删除收藏夹
    @DeleteMapping("/{favoritesId}")
    public R<String> delFavorites(@PathVariable Long favoritesId) {
        boolean b = favoritesService.delFavorites(favoritesId);
        if (b) {
            R.success("删除收藏夹成功");
        }
        return R.error("删除收藏夹失败");
    }

@DeleteMapping("/{id}")
    public R<String> delEq(@PathVariable Long id) {
        favoritesService.delEq(id);
        return R.success("取消收藏成功");
    }

解决

该问题是因为Mapping的value值的url值一样造成的(参数名不同不会造成影响，因为返回数据是相同形式)，所以只需要修改Mapping的value值就可以了

 @DeleteMapping("/del/{id}") //eg
