更改hibernate.cfg.xml运行时 - 第二部分

时间:2014-11-18 16:00:25

标签: java spring hibernate.cfg.xml

我试图使用混合形式来定义SessionFactory,因为我想允许用户使用我的webapp(SpringMVC + hibernate),第一次交互,定义访问数据库的凭据。 / p>

我定义了以下文件:

的hibernate.cfg.xml

<hibernate-configuration>
   <session-factory>
    <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
    <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>        

     <mapping resource="com/appDial/hibernateGenerate/Eventlog.hbm.xml" />
    ....
   </session-factory>
</hibernate-configuration>

HibernateSessionFactory.java

public class HibernateSessionFactory {

private static final ThreadLocal<Session> threadLocal = new ThreadLocal<Session>();
private static org.hibernate.SessionFactory sessionFactory;

private static Configuration configuration = new Configuration();
private static String CONFIG_FILE_LOCATION = "/hibernate.cfg.xml";
private static String configFile = CONFIG_FILE_LOCATION;

static {
    try {
        configuration.configure(configFile);
        sessionFactory = configuration.buildSessionFactory();
    } catch (Exception e) {
        System.err.println("%%%% Error Creating SessionFactory %%%%");
        e.printStackTrace();
    }
}

private HibernateSessionFactory() {
}

/**
 * Returns the ThreadLocal Session instance.  Lazy initialize
 * the <code>SessionFactory</code> if needed.
 *
 *  @return Session
 *  @throws HibernateException
 */
public static Session getSession() throws HibernateException {
    Session session = (Session) threadLocal.get();

    if (session == null || !session.isOpen()) {
        if (sessionFactory == null) {
            rebuildSessionFactory();
        }
        session = (sessionFactory != null) ? sessionFactory.openSession()
                : null;
        threadLocal.set(session);
    }

    return session;
}

/**
 *  Rebuild hibernate session factory
 *
 */
public static void rebuildSessionFactory() {
    try {
        configuration.configure(configFile);
        sessionFactory = configuration.buildSessionFactory();
    } catch (Exception e) {
        System.err.println("%%%% Error Creating SessionFactory %%%%");
        e.printStackTrace();
    }
}

/**
 *  Close the single hibernate session instance.
 *
 *  @throws HibernateException
 */
public static void closeSession() throws HibernateException {
    Session session = (Session) threadLocal.get();
    threadLocal.set(null);

    if (session != null) {
        session.close();
    }
}

/**
 *  return session factory
 *
 */
public static org.hibernate.SessionFactory getSessionFactory() {
    return sessionFactory;
}

/**
 *  return session factory
 *
 *  session factory will be rebuilded in the next call
 */
public static void setConfigFile(String configFile) {
    HibernateSessionFactory.configFile = configFile;
    sessionFactory = null;
}
/**
 *  return hibernate configuration
 *
 */
public static Configuration getConfiguration() {
    return configuration;
}

public static void setProperties(String urlDB, String username,
        String password) {


    try{
        HibernateSessionFactory.configuration=new AnnotationConfiguration();

        HibernateSessionFactory.configuration.setProperty("hibernate.connection.url", urlDB);
        HibernateSessionFactory.configuration.setProperty("hibernate.connection.username", username);
        HibernateSessionFactory.configuration.setProperty("hibernate.connection.password", password );  

        HibernateSessionFactory.configuration.configure();

        HibernateSessionFactory.sessionFactory=HibernateSessionFactory.configuration.buildSessionFactory();
    }catch(Exception e){
        System.out.println(e.getMessage());
    }

}

}

调度-servlet.xml中

.....
 <tx:annotation-driven/>

 <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" >
    <property name="sessionFactory" ref="sessionFactory" /> 
</bean>
......

输入数据库后,凭证似乎是SessionFactory的初始化成功,但只是尝试与DAO对象进行交互我得到了这个错误:

我怀疑是由于在部署期间初始化的TransactionManager,但是没有凭据的SessionFactory。
