老师，前台商品列表报20000的错，商品详情postman报404，商品详情日志有记录

其中代码如下

Product (Integer id){
    Product product=.selectByPrimaryKey(id)product}
PageInfo (ProductListReq productListReq){
    ProductListQuery productListQuery=ProductListQuery()(!StringUtils.(productListReq.getKeyword())){
        String keyword=StringBuilder().append().append(productListReq.getKeyword())
                .append().toString()productListQuery.setKeyword(keyword)}
    (productListReq.getCategoryId() !=){
       List<CategoryVo> categoryVoList= .listCategoryForCustomer(productListReq.getCategoryId())ArrayList<Integer> categoryIds=ArrayList<>()categoryIds.add(productListReq.getCategoryId())getCategoryIds(categoryVoListcategoryIds)productListQuery.setCategoryIds(categoryIds)}
    String orderBy = productListReq.getOrderBy()(ProductListOrderBy..contains(orderBy)){
        PageHelper.(productListReq.getPageNum()productListReq.getPageSize()orderBy)}{
        PageHelper.(productListReq.getPageNum()productListReq.getPageSize())}

    List<Product> productList=.selectList(productListQuery)PageInfo pageInfo=PageInfo(productList)pageInfo}
(List<CategoryVo> categoryVOListArrayList<Integer> categoryIds){
    (i=i<categoryVOList.size()i++){
        CategoryVo categoryVO=categoryVOList.get(i)(categoryVO !=){
            categoryIds.add(categoryVO.getId())getCategoryIds(categoryVO.getChildCategory()categoryIds)}
    }
}

ProductController {
    ProductService ()
    ()
    ApiRestResponse (Integer id){
        Product product=.detail(id)ApiRestResponse.(product)}
    ()
    ()
    ApiRestResponse (ProductListReq productListReq){
        PageInfo list=.list(productListReq)ApiRestResponse.(list)}
}
