tomcat restart =>找不到SessionFactory [uuid = ...，name = null] [英] tomcat restart => Could not find a SessionFactory [uuid=...,name=null]

问题描述

继续解决这种情况，我已更新 hibernate ond sqljdbc4 jars 现在异常已被修改（请看一看

使用

• Hibernate v4.1.4 FINAL


• JSF 2.1（mojarra）
  
• 所有我的 @ManagedBeans 执行可串行化

它与 @ViewScoped ，因为 @SessionScoped bean都可以使用

我尝试过：

• 启用< Manager pathname =/>在context.xml 中，是的，异常消失了，但我真的失去了永久会话，所以我必须在tomcat服务器重新启动后重新登录。




• 在hiberanate.cfg.xml文件中进行更改（例如将 name =java：hibernate / SessionFactory添加到< session-




• 使用 SESSIONS.ser 文件，它是在 STOP tomcat服务器之后创建的。

  
  
  
  
  
  • 当我打开 ser文件时，我可以找到如下所示的内容：.... <$ c $如果我再次START tomcat服务器，则可以使用
    
  • 
    
  它报告找不到SessionFactory [uuid = 8906373-f31b-4990-833c-c7680b2a77ce，name = null] - WHY ??? session似乎存在于 SESSION.ser 文件中......
  

我的会话管理器：

  @SessionScoped 
 @ManagedBean（name =userManager）
 public class UserManager实现Serializable {
 private static final long serialVersionUID = 1L; 
私有瞬态HttpSession会话; 
私人字符串用户名; 
私人字符串密码; 
私人用户用户; 
 $ b $ public String login（）{
 //这里是为数据库中的用户进行分页（基于用户名和密码）
 
 if（user！= null）{ 
 FacesContext context = FacesContext.getCurrentInstance（）; 
 session =（HttpSession）context.getExternalContext（）。getSession（true）; 
 session.setAttribute（id，user.getId（））; 
 session.setAttribute（username，user.getName（））; 
 ... 
返回成功; 
 
 
 
 public String logout（）{
 user = null; 
 FacesContext context = FacesContext.getCurrentInstance（）; 
 session =（HttpSession）context.getExternalContext（）。getSession（true）; 
 ... 
 session.invalidate（）; 
返回成功; 
} 
 // getters and setters ------------------------------------ ---------------- 
} 
  

我的 hibernate.cfg.xml ：

 <？xml version = 1.0encoding =UTF-8？> 
<！DOCTYPE hibernate-configuration PUBLIC 
 -  // Hibernate / Hibernate配置DTD 3.0 // EN
http://www.hibernate.org/dtd/hibernate-configuration -3.0.dtd>

和我的会话工厂：

  public final class DaoSF implements Serializable {
 private static final long serialVersionUID = 1L; 
 
 private static SessionFactory sessionFactory; 
 private static ServiceRegistry serviceRegistry; 
 
 public static SessionFactory getSessionFactory（）{
 try {
 Configuration configuration = new Configuration（）; 
 configuration.configure（hibernate.cfg.xml）; 
 serviceRegistry = new ServiceRegistryBuilder（）。applySettings（configuration.getProperties（））。buildServiceRegistry（）; 
 sessionFactory = configuration.buildSessionFactory（serviceRegistry）; 
 return sessionFactory; 
 
 catch（HibernateException he）{
 ... 
} 
} 
} 
  

异常：

我尝试用这种方式编辑我的 hibernate.cfg.xml 文件：

 < session-factory name =java：hibernate / SessionFactory> 
  

错误报告已更改为：

您是否遇到过这个错误报告？

解决方案

您不希望 Session ， SessionFactor y 或 DaoSF 进行序列化。它们是暂时的，不能从文件中恢复。你最好弄清楚它们在哪里以及为什么序列化到文件中。这就是您需要修复的地方。

Continue solving this situation, I've updated hibernate ond sqljdbc4 jars and the exception is changed now (please take a look bellow).

I'm using

• Hibernate v4.1.4 FINAL
• JSF 2.1 (mojarra)
• all my @ManagedBeans implements Serializable

It has some relation to @ViewScoped, because @SessionScoped beans are OK

What I've tried:

• enable <Manager pathname=""/> in context.xml, and yes, the exception disappears, but I really lose persistent sessions, so I have to login again after tomcat server restart.

• make changes in hiberanate.cfg.xml file (e.g. add name="java:hibernate/SessionFactory" to <session-factory> tag), but without success

• play with SESSIONS.ser file, which is created after STOP the tomcat server.

  • When I open ser file, I can find there something like: .... uuidq ~ xppt $e8906373-f31b-4990-833c-c7680b2a77ce ...
  • if i START tomcat server again, it reports Could not find a SessionFactory [uuid=8906373-f31b-4990-833c-c7680b2a77ce,name=null] - WHY??? The session seems to be present in SESSION.ser file...

My session manager:

@SessionScoped
@ManagedBean(name="userManager")
public class UserManager implements Serializable {
  private static final long serialVersionUID = 1L;
  private transient HttpSession session;
  private String username;
  private String password;
  private User user;

  public String login() {
    // here is seraching for user in database (based on username and password)

    if (user != null) {
      FacesContext context = FacesContext.getCurrentInstance();
      session = (HttpSession) context.getExternalContext().getSession(true);
      session.setAttribute("id", user.getId());
      session.setAttribute("username", user.getName());
      ...
      return "success";
    } 
  }

  public String logout() {
    user = null;
    FacesContext context = FacesContext.getCurrentInstance();
    session = (HttpSession) context.getExternalContext().getSession(true);
    ...     
    session.invalidate();
    return "success";
  }
  // getters and setters ----------------------------------------------------
}

my hibernate.cfg.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC 
  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
 <session-factory>
  <property name="connection.url">jdbc:sqlserver://localhost;databaseName=RXP</property>
  <property name="connection.username">user</property>
  <property name="connection.password">password</property>
  <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
  <property name="dialect">org.hibernate.dialect.SQLServer2008Dialect</property>
  <property name="current_session_context_class">thread</property>
  <property name="hibernate.show_sql">true</property>
  <property name="hibernate.hbm2ddl.auto">update</property>

  <mapping class="tables.User"/>

 </session-factory>
</hibernate-configuration>

and my session factory:

public final class DaoSF implements Serializable {
  private static final long serialVersionUID = 1L;

  private static SessionFactory sessionFactory;
  private static ServiceRegistry serviceRegistry;

  public static SessionFactory getSessionFactory() {
    try {
      Configuration configuration = new Configuration();
      configuration.configure("hibernate.cfg.xml");
      serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();        
      sessionFactory = configuration.buildSessionFactory(serviceRegistry);
      return sessionFactory;
    }
    catch (HibernateException he) { 
      ...
    }
  }
}

exception:

30.6.2012 13:29:07 org.apache.catalina.session.StandardManager doLoad
SEVERE: IOException while loading persisted sessions: java.io.InvalidObjectException: Could not find a SessionFactory [uuid=f9c33312-cf7f-4f65-ae5f-44261705c18e,name=null]

    at org.hibernate.internal.SessionFactoryImpl.deserialize(SessionFactoryImpl.java:2037)
....

I've tried to edit my hibernate.cfg.xml file this way:

<session-factory name="java:hibernate/SessionFactory">

And the error reportd has been changed to:

30.6.2012 13:38:23 org.apache.catalina.session.StandardManager startInternal
SEVERE: Exception loading sessions from persistent storage

....

Don't you ever met with this error reports?

解决方案

You don't want instances of Session, SessionFactory or DaoSF to be serialized. They are transient and cannot be restored from a file. You better figure out where and why they are serialized to a file in the first place. That's where you need to make a fix.
