这也是我的服务班

package com.test.spring.web.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.test.spring.web.dao.User;
import com.test.spring.web.dao.UsersDAO;

@Service("toDoService")
public class ToDoService {

    private UsersDAO usersDao;

    public UsersDAO getUsersDAO() {
        return usersDao;
    }

    @Autowired
    public void setUsersDAO(UsersDAO usersDAO) {
        this.usersDao = usersDAO;
    }

    public void create(User user) {
        usersDao.create(user);

    }

}

请在这方面提供一点帮助。我已经浪费了一整天的时间来寻找解决办法。提前致谢

很抱歉，我无法将其放入评论中，但为什么您会依赖于：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate</artifactId>
    <version>3.5.4-Final</version>
    <type>pom</type>
</dependency>

当你移除它时会发生什么？
