Question

我是java spring技术的新手。我想从java spring controller中调用modal中的getFunction。

@RequestMapping(value = "/category/pagination-mobile/{categoryId}/{currentCity}", method = RequestMethod.POST)
    @ResponseBody
    public Map<String, String> paginationMobile(ModelMap model, @PathVariable int categoryId, @PathVariable int currentCity, HttpServletRequest request, HttpServletResponse response) {
        Map<String, String> resp = new HashMap<>();
        List<CityProduct> cityProducts = productService.getCityProductsForCategoryForWeb(categoryId, currentCity, 15, false);
        request.setAttribute("products", cityProducts);
        request.setAttribute("categoryId", categoryId);
        System.out.println("-------------->  " + cityProducts.getPrice());
        String paginationFirstPage = getHtmlResponse(request, response, "/WEB-INF/jsp/catalog/_categoryFirst.jsp");
        resp.put("html", paginationFirstPage);
        return resp;
    }

的.java

public class CityProduct implements Serializable {
 public CityProduct(Product p, ProductOfCity pc) {
 this.price = pc.getPrice();

}

 public BigDecimal getPrice() {
        return price;
    }

    public void setPrice(BigDecimal price) {
        this.price = price;
    }

}

我想从模态中获取所有价格。如何获取弹簧控制器的所有价格。

Answer 1

cityProducts是List的对象，您无法在getPrice对象上调用cityProdycts方法。您必须迭代List，如下所示，使用getPrice方法获取每种产品的价格。

for(CityProduct cityProduct : cityProducts){
    System.out.println(cityProduct.getPrice());
}

如果你想要一些逻辑来实现超价，你可以在for循环中实现。

从Spring控制器调用Java Modal函数？
