Hibernate 无法执行JDBC批处理更新如何解决此问题

我在Hibernate中执行一个基本操作。我有一个带有注释的实体类，还有一个运行应用程序的主类。但是它的显示无法执行JDBC批处理更新。这是我的密码

实体类

import javax.persistence.Entity;
import javax.persistence.Id;




@Entity

public class UserDetails {
@Id
private int userId;
private String userName;

public int getUserId() {
    return userId;
}
public void setUserId(int userId) {
    this.userId = userId;
}
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
}
}

这是hibernate.cfg

<?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>

<!-- Database Connection setting -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property    name="hibernate.connection.url">jdbc:mysql://localhost:3306/hibernate</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.connection.pool_size">2</property>
<property name="hibernate.current_session_context_class">thread</property>
<property  name="hibernate.cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<property name="show_sql">true</property>

<property name="hbm2ddl">Create</property>
<mapping class="org.jeet.dto.UserDetails"/>
</session-factory>


</hibernate-configuration>

你能发布错误消息吗。代码正在运行。。只编辑了一部分

  <property name="hibernate.hbm2ddl.auto">update</property>

更新

而不是

  <property name="hbm2ddl">Create</property>

创建

在hibernate.cfg.xml中。发布错误消息（如果有）

  <property name="hbm2ddl">Create</property>
