弄了一晚上，就是无法自动创建表，单元测试通过了，没报错，就是不能创建表，用的是sqlServer2008，数据库连接是没问题的，在线等大神

code如下：

persistence.xml

<?xml version="1.0"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">
<!-- file:///D:\hibernate\hibernate-entitymanager-3.3.2.CR1\resources\org\hibernate\ejb\persistence_1_0.xsd -->
<persistence-unit name="demo" transaction-type="RESOURCE_LOCAL">

<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
<property name="hibernate.connection.driver_class" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/>
<property name="hibernate.connection.username" value="sa"/>

<property name="hibernate.jdbc.batch_size" value="10"/>
<property name="hibernate.show_sql" value="false"/>
<property name="hibernate.format_sql" value="false"/>
</properties>

java代码

package com.hongle.bean.product;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class ProductType {
private int typeId;

@Id @GeneratedValue(strategy=GenerationType.AUTO)
public int getTypeId() {
return typeId;
}

public void setTypeId(int typeId) {
this.typeId = typeId;
}


}


java代码

package junit.test;

import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

import org.junit.BeforeClass;
import org.junit.Test;

import junit.framework.TestCase;

public class ProductTest{

@BeforeClass
public static void setUpBeforeClass() throws Exception {
}

@Test
public void testRun(){
Persistence.createEntityManagerFactory("demo");

}

}

可恨的是没有报错，改都不知道怎么改
