java.lang.IllegalStateException:尝试对已关闭的EntityManagerFactory执行操作

时间:2012-03-30 16:57:52

标签: mysql jsf jpa amazon-ec2 glassfish

我使用Eclipse Indigo来开发使用Glassfish 3 Open Source的JSF 2项目,这在我的计算机中,然后在我的EC2实例中,在Amazon AWS中,对于Glassfish,我创建了一个JDBC连接池,用于我的JPA实体经理。

本地我的项目工作得很好,但是当我部署项目并尝试执行相同的表单时,它会从运行GlassFIsh的同一实例EC2中运行的数据库获取一些值。

我收到此消息:

enter image description here

serverError:class javax.faces.el.E​​valuationException

我在搜索它,但到目前为止我找不到任何东西。

我有什么配置可以帮助它吗?

编辑2: 这就是我使用EntityManager的方式:

@Stateless(mappedName = "logEAO")
@LocalBean
public class LogEAO {
    @PersistenceContext
    private EntityManager em;

    public LogEAO() {}


    public Log find(int id) {
        return em.find(Log.class, id);
    }
    // .. 

3 个答案:

答案 0 :(得分:18)

如果您正在使用Glassfish服务器,请重新启动服务器为我完成。

答案 1 :(得分:8)

来自你的堆栈跟踪:

  

引起:java.lang.IllegalStateException:试图对已关闭的EntityManagerFactory执行操作。

您的EJB代码看起来很好。这更像是Glassfish错误或配置错误:


这只能意味着您手动管理EntityManagerFactory(和EntityManager)而不是让容器只通过@PersistenceContext来完成工作。

<击>

EntityManagerFactory打算在webapp启动时只创建一次,在整个webapp的生命周期内重用,并在webapp关闭时关闭。它不应该在某个中途关闭,或者被序列化并重新用于下一个重启周期。

由于您显然是针对Glassfish,我强烈建议您不要自行管理,而是让Glassfish完成这项工作。您最终会得到更简单的EJB代码,而无需手动管理事务。

另见:

答案 2 :(得分:3)

我遇到了这个问题并找到了解决方案。

问题是eclipse(使用glassfish插件)只启动/停止域而不是数据库。

步骤:

  1. 从命令行/外部eclipse启动数据库
  2. 在eclipse中启动服务器(域)
  3. 使用@PersistenceContext注入部署应用程序 - &gt;原理
  4. 详细说明:

    我退出了eclipse - 这停止了glassfish服务器。然后关闭机器 - 停止数据库。重新启动时,打开eclipse,启动服务器并尝试部署相同的应用程序。失败,错误:

    Deployment Error for module xxx
    Error occurred during deployment: Exception while preparing the app :
    Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): 
    org.eclipse.persistence.exceptions.DatabaseException
    Internal Exception: java.sql.SQLException: Error in allocating a connection.
    Cause: Connection could not be allocated because: java.net.ConnectException :
    Error connecting to server localhost on port 1527 with message Connection refused
    

    数据库未启动的原因。所以从命令行启动数据库。得到错误

    java.lang.IllegalStateException: Attempting to execute an operation on a closed EntityManagerFactory
    

    然后按照上面的步骤进行操作。


    修改 以上步骤有时会解决问题,但在GF 3.0 / 3.1中它似乎也是一个众所周知的问题:http://java.net/jira/browse/GLASSFISH-17295

    另一种选择是从管理控制台重新部署应用程序,如下所述:http://richardchesterwood.blogspot.in/2011/09/javaee-course-ships-with-copy-of-javaee.html
