奇怪的hibernate.hbm2ddl.auto行爲

我部署了一個應用程序hibernate.hbm2ddl.auto =創建，發現我的很多表被丟棄！我曾經做過同樣的事情，但是使用EclipseLink而不是Hibernate，數據庫返回表已經存在，這意味着它只啓動create table。我懷疑有hibernate.hbm2ddl.auto設置爲「創建」，如果刪除，然後創建表。奇怪的hibernate.hbm2ddl.auto行爲

任何人都可以證實我的疑惑？感謝您的幫助。

這是我的hibernate配置文件，它的工作原理。

<!DOCTYPE hibernate-configuration PUBLIC 
    "-//Hibernate/Hibernate Configuration DTD//EN" 
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> 
<hibernate-configuration> 
    <session-factory> 

     <!-- Database connection settings --> 
     <property name="connection.driver_class">org.h2.Driver</property> 
     <property name="connection.url">jdbc:h2:tcp://localhost/mem:test:MVCC=true;INIT=create schema IF NOT EXISTS OVT;DB_CLOSE_DELAY=10</property> 
     <property name="connection.username">sa</property> 
     <property name="connection.password"></property> 

     <!-- JDBC connection pool (use the built-in) --> 
     <property name="connection.pool_size">100</property> 

     <!-- SQL dialect --> 
     <property name="dialect">org.hibernate.dialect.H2Dialect</property> 

     <!-- Disable the second-level cache --> 
     <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property> 

     <!-- Echo all executed SQL to stdout --> 
     <property name="show_sql">true</property> 

     <!-- Drop and re-create the database schema on startup --> 
     <property name="hbm2ddl.auto">create</property> 

     <mapping class="model.concretes.varlik.Tasit" /> 
     <mapping class="model.concretes.varlik.Kisi" /> 
     <mapping class="model._framework.concretes.varlik.Log" /> 
     <mapping class="model._framework.concretes.varlik.Yetki" /> 
    </session-factory> 
</hibernate-configuration>
