Java Spring MVC-休眠错误，can'；t运行项目

我和另外17个人在一个github项目（）上。问题是我不能运行这个项目，我不知道错误是什么。我做了很多研究，但找不到该做什么。（我们对hibernate和spring几乎没有经验）。这是一门课程

以下是控制台错误：

请参阅

在
Busqueda2Controller
类中，您有两个具有相同映射的方法：

@RequestMapping(value="",method=RequestMethod.GET)

这当然行不通，因为您实际上是在将两个方法映射到同一个URL

您需要做的是更改每个注释的
值
以指向不同的内容。
在这个公共的org.springframework.web.servlet.ModelAndView web.ecommerce.tpfinal.ecommerce\u web.controller.Busqueda2Controller.busqueda（int，int）映射中，您的控制器（spring mvc）中存在一些模糊映射。
