無法使用Hibernate和Servlet創建SessionFactory

任何人都可以幫我解決這個問題。我的配置是使用Maven： - 休眠4.3.6 - servlet的3.0.1 - MySQL的5.1.12 - 作爲JBoss 7.1.1無法使用Hibernate和Servlet創建SessionFactory

當我嘗試運行我的申請，我得到這個錯誤信息：

11:15:07,298 ERROR [stderr] (http-localhost-127.0.0.1-8080-1) Initial SessionFactory creation failed.java.lang.NoSuchMethodError: javax.persistence.JoinColumn.foreignKey()Ljavax/persistence/ForeignKey;

我的代碼：

@WebServlet("/employee") 
    public class EmployeesServlet extends HttpServlet { 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) 
       throws ServletException, IOException { 
    List<Employees> employees = new ArrayList<Employees>(); 
    IEmployeesBusiness employeesBusiness = new EmployeesBusinessImpl(); 
    Employees employee = employeesBusiness.getEmployee(1056); 
    request.getSession().setAttribute("employee", employee); 
    response.sendRedirect("employees.jsp"); 
    } 
}

employes.jsp

此類測試工作正常，但是當我嘗試在JSP中顯示的結果，我得到的錯誤告訴我，會話不能初始化

public class Test { 

    public static void main(String[] args) { 

     Employees employee = new Employees(); 

     Session session = HibernateUtil.getSessionFactory().openSession(); 
     session.beginTransaction(); 

     List<Employees> employees = new ArrayList<Employees>(); 

     IEmployeesBusiness employeesBusiness = new EmployeesBusinessImpl(); 

     Employees emp = employeesBusiness.getEmployee(1056); 

     session.getTransaction().commit(); 
     session.close(); 

     System.out.println(emp.getFirstName()); 

    } 
}

發佈您的代碼將非常有幫助 – 2014-08-30 09:21:18

@cozia在我的映射中存在一些問題。檢查如何配置實體之間的關聯 – Skizzo 2014-08-30 14:10:14

尤里卡！我找到了它。我將我的hibernate的版本更改爲MAVEN依賴項中的4.3.6.Final。

<dependency> 
    <groupId>org.hibernate</groupId> 
    <artifactId>hibernate-core</artifactId> 
    <version>**4.3.6.Final**</version> 
</dependency>

這個版本的hibernate與jpa 2.0兼容（但不能與jpa 2.1兼容）。在jpa 2.0中，屬性@JoinColumn（「foreignKey =」）不是必需的。

在我得到這個錯誤之前： javax.persistence.JoinColumn.foreignKey（）Ljavax/persistence/ForeignKey;
