hibernate向mysql插入数据失败！
运行程序的结果是：Exception in thread "main" org.hibernate.exception.SQLGrammarException: could not insert: [lee.News]；
Caused by: java.sql.SQLException: Table 'hibernates.news_table' doesn't exist
奇怪的是数据没有插入成功，反而自动把表给删除了。。。。
纠结了好长时间，请懂的朋友支援，谢谢！！

mysql:
create table news_table (
news_id int primary key auto_increment,
news_title varchar(20) not null,
content varchar(50) not null );

News.java :
package lee;
public class News {
private Integer id;
private String title;
private String content;

public News() {}
public News(Integer id, String title, String content) {
this.setId(id);
this.setTitle(title);
this.setContent(content);
}

public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}

Test.java :
package lee;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

public class Test {
public static void main(String[] args) throws Exception
{
//实例化Configuration
Configuration conf = new Configuration().configure();
//实例化SessionFactory
SessionFactory sf = conf.buildSessionFactory();
//实例化Session
Session sess = sf.openSession();
//开始事务
Transaction tx = sess.beginTransaction();
//创建消息实例
News n = new News();
//设置消息标题和消息内容
n.setTitle("疯狂Java联盟成立了");
n.setContent("疯狂Java联盟成立了，网址是www.crazyit.org");
//保存消息
sess.save(n);
//提交事务
tx.commit();
//关闭Session
sess.close();
}
}

[解决办法]
create应该是先删除再创建的，没看出什么问题
[解决办法]
不需要你写mysql语句，它会自动创建表，
建议使用
<property name="hbm2ddl.auto">update</property>
