任何人都可以帮助我解决这个问题。 我的配置是使用Maven： - Hibernate 4.3.6 - servlet 3.0.1 - mysql 5.1.12 - Jboss AS 7.1.1

当我尝试运行我的应用程序时，收到此错误消息：

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;

我的代码：

    @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");
    }
 }

这个类测试工作正常但是当我尝试在jsp中显示结果时，我得到了错误 告诉我Session无法初始化

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());

    }
}

答案 0 :(得分：0)

尤里卡！我找到了。我将我的hibernate的版本更改为MAVEN依赖项中的4.3.6.Final。

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

这个版本的hibernate与jpa 2.0兼容（但不与jpa 2.1兼容）。使用jpa 2.0，属性@JoinColumn（＆＃34; foreignKey =＆＃34;）不是必需的。

在我收到此错误之前： javax.persistence.JoinColumn.foreignKey（）Ljavax /持久/ ForeignKey的;
