我在Spring中创建简单的上下文以使其处理hibernate的东西。您可以找到我的项目here。

我在这里创建上下文：
package com.pizzaa.application;
import com.pizzaa.application.interfaces.AdminService;
import com.pizzaa.domain.admin.Admin;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
/**
* Created by jjpikoov on 5/14/16.
*/
public class App {
public static void main(String [] args) {
// AbstractApplicationContext context = new AnnotationConfigApplicationContext(Config.class);
AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();
context.register(Config.class);
context.refresh();
AdminService adminService = (AdminService) context.getBean("adminService");
Admin a1 = new Admin();
a1.setLogin("jjpikoov");
a1.setPassword("jjpassw");
a1.setEmail("emailjj");
adminService.addAdmin(a1);
context.close();
}
}

我几乎尝试了一切。你知道我做错了什么吗？提前谢谢。
答案 0 :(得分：0)
是版本问题。
从bean类中删除@Configuration。希望它能解决你的问题。
