Java hibernate main中的异常

我在尝试运行storedata.java文件时出现上述错误。我刚开始使用hibernate，请帮助我

Employee.java

StoreData.java

package com.javatpoint.mypackage;
public class Employee {
private int id;  
private String firstName,lastName;  
public int getId() {  
return id; 
}
public void setId(int id) {  
this.id = id;  
enter code here
}
public String getFirstName() {  
return firstName; }
public void setFirstName(String firstName) {  
this.firstName = firstName; 
}  
 public String getLastName() {  
return lastName;  
}  
public void setLastName(String lastName) {  
this.lastName = lastName;  
}  
}

employee.hbm.xml

package com.javatpoint.mypackage;



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

   public class StoreData {  
   public static void main(String[] args) {  

   //creating configuration object  
   Configuration cfg=new Configuration();  
   cfg.configure("hibernate.cfg.xml");
   //populates the data of             the         configuration file  

    //creating seession factory object  
    SessionFactory factory=cfg.buildSessionFactory();  

//creating session object  
Session session=factory.openSession();  

//creating transaction object  
Transaction t=session.beginTransaction();  

Employee e1=new Employee();  
e1.setId(115);  
e1.setFirstName("sonoo");  
e1.setLastName("jaiswal");  

session.persist(e1);//persisting the object  

t.commit();//transaction is committed  
session.close();  

System.out.println("successfully saved");  

}  
}

我已经为hibernate插入了所有必要的jar文件，并正确配置了mysql。

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.

log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.

log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x 
-         %m%n**strong text**

朋友们，我的问题解决了，执行得很好。我在“hibernate.cfg.xml”文件中做了一个更改。这里的更改是

          `      

而不是

<?xml version="1.0"?>

鉴于UTF-8已经是默认编码，您的回答毫无意义。如果这确实解决了你的问题，那是因为你不经意间。

          `      

<?xml version="1.0"?> 

<?xml version="1.0" encoding="UTF-8"?>
