控制器

package com.creativecapsule.Controller;

import com.creativecapsule.Entity.Employee;
import com.creativecapsule.Service.EmployeeService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.Collection;

/**
 * Created by sandip on 02/22/2017.
 */
@RestController
@RequestMapping("/employees")
public class EmployeeController {
    @Autowired
    private EmployeeService employeeService;
    @RequestMapping(method = RequestMethod.GET)
    public String saveEmployee(){
        Employee emp = new Employee();
        emp.setId(1);
        emp.setName("Ram");
        System.out.println("Check value in controller-------->" + emp.getName());
        return employeeService.saveEmployee(emp);

    }
}

道

package com.creativecapsule.Dao;

import com.creativecapsule.Entity.Employee;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import java.util.Collection;
import java.util.Hashtable;
import java.util.Map;

/**
 * Created by sandip on 02/22/2017.
 */
@Repository
@Transactional
public class EmployeeDao {

@Autowired
private SessionFactory session;


    public Collection<Employee> getAllEmployees()
    {
        return this.employees.values();
    }

    @Transactional
    public String saveEmployee(Employee emp){
        try {
            System.out.println("Check value in Dao-------->" + emp.getName());
            session.getCurrentSession().save(emp);
        } catch(Exception ex){
            ex.printStackTrace();
            return "error";
        }
        return  "success";
    }

我尝试了@Transactional和其他解决方案，但它仍然抛出此错误。

现在我用session.openSession（）尝试了它.save（emp）;它抛出errororg.hibernate.MappingException：未知实体：com.creativecapsule.Entity.Employee
