求指教：hibernate类初始化时报错org.hibernate.HibernateException，研究半天了，没发现哪有问题
这是第一次做个例子---在初始化这块报错 --------还请不吝指教！谢过Exception in thread "main" org.hibernate.HibernateException: could not instantiate RegionFactory [org.hibernate.cache.internal.NoCachingRegionFactory]

下面是我的类初始化数据
package com.excercise.hibernate;
import java.util.Date;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class Client {
public static void main(String[] arg){
//读取配置文件
Configuration cfg=new Configuration().configure();
//一个数据库对应一个SessionFactory--创建
SessionFactory factory=cfg.buildSessionFactory();
//
Session session=null;
try{
session=factory.openSession();
session.beginTransaction();
User user = new User();
user.setName("陈晨");
user.setPassword("samma0921");
user.setCreateTime(new Date());
user.setExpireTime(new Date());
session.save(user);
session.getTransaction().commit();
}catch(Exception e){
e.printStackTrace();
session.getTransaction().rollback();
}finally{
if(session!=null){
if(session.isOpen()){
session.close();
}
}
}
}
}

这是我的hibernate.cfg.xml配置
<!DOCTYPE hibernate-configuration PUBLIC

下面是我的user映射文件----user.hbm.xml配置
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC

----------------------------------------------------------------
这是是我的pojo对象----user.java
package com.excercise.hibernate;
import java.util.Date;
public class User {
private String id;
private String name;
private String password;
private Date createTime;
private Date expireTime;
public String getId() {
return id;

public void setId(String id) {
this.id = id;
}
public String getName() {
return name;

public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Date getCreateTime() {
return createTime;
}
public void setCreateTime(Date createTime) {
this.createTime = createTime;
}
public Date getExpireTime() {
return expireTime;
}
public void setExpireTime(Date expireTime) {
this.expireTime = expireTime;
}
}
------------------------------------------------------------------
这是我的表生成工具----ExportDB.java
package com.excercise.hibernate;
import org.hibernate.cfg.Configuration;
import org.hibernate.tool.hbm2ddl.SchemaExport;
public class ExportDB {
public static void main(String[] args){
//读取hibernate.cfg.xml文件
Configuration cfg=new Configuration().configure();
SchemaExport export=new SchemaExport(cfg);
export.create(true, true);
}
} Hibernate --------------------编程问答-------------------- 没有路过的么，自己顶起来！ --------------------编程问答-------------------- 类型转换错误，应该是包的问题 --------------------编程问答-------------------- 是不是缺少了 oscache.jar这个jar包？ --------------------编程问答-------------------- 谢谢，好像不是这个问题，不过自己弄好了，弄好之后又将这个jar包删了，还是好用的！自己都有点糊涂到底是怎么回事，不过还是多谢！
