我有一个带有Spring MVC的简单Java应用程序（下面的代码）。在那里，我想做小商店，并获得产品frob数据库。当我尝试从IDEA运行Tomcat时，我得到下一个错误：

这是我的应用：

MainController：

package com.shop.cond;

import com.shop.cond.model.Product;
import com.shop.cond.service.ProductServiceImpl;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class MainController {

    private ProductServiceImpl trackService;

    @Autowired(required = true)
    @Qualifier("productService")
    public void setTrackService(ProductServiceImpl ts) {
        this.trackService = ts;
    }

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String listTracks(Model model) {
        model.addAttribute("product", new Product());
        model.addAttribute("listProducts", this.trackService.listProducts());
        return "homePage";
    }
}
