productcategorymanagement.css

.row-product-category {
    border: 1px solid #999;
    padding: .5rem;
    border-bottom: none;
}
.row-product-category:last-child {
    border-bottom: 1px solid #999;
}
.category-input {
    border: none;
    background-color: #eee;
}
.product-category-name {
    white-space: nowrap;
    overflow-x: scroll;
}

同时更改路由

1     @RequestMapping(value = "/productcategorymanagement",method=RequestMethod.GET)
2     public String productcategoryList() {
3         return "shop/productcategorymanagement";
4     }
