使用Hibernate向MySQL插入數據時出錯Error

HI我正在使用Hibernate在eclipse中開發項目。我發現這個錯誤在我的hibernate.cfg.xml文件中使用Hibernate向MySQL插入數據時出錯Error

請幫助解決這個問題。

我已經包含了所有必需的庫。

的hibernate.cfg.xml

<hibernate-configuration> 
    <session-factory> 



     <!-- Related to the connection START --> 
     <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 
     <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property> 
     <property name="connection.user">root</property> 
     <property name="connection.password">93Pb3gaNv0</property> 
     <!-- Related to the connection END --> 

     <!-- Related to hibernate properties START --> 
     <property name="show_sql">true</property> 
     <property name="dailet">org.hibernate.dialect.MySQLDialect</property> 
     <property name="hbm2ddl.auto">update </property> 
     <!-- Related to hibernate properties END --> 

     <!-- Related to mapping START --> 
     <mapping resource="user.hbm.xml"/> 
     <!-- Related to mapping END --> 




    </session-factory> 
</hibernate-configuration>

user.hbm.xml

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

 <hibernate-mapping> 
     <class name="mypack.DataProvider" table="user_info"> 
     <id name="user_id" column="id"> 
     <generator class="assinged"></generator> 
     </id> 
     <property name="user_name" column="name"></property> 
     <property name="user_address" column="address"></property> 
     </class> 
     </hibernate-mapping>

DataProvider.java

package mypack; 

public class DataProvider { 

private int user_id; 
public int getUser_id() { 
    return user_id; 
} 
public void setUser_id(int user_id) { 
    this.user_id = user_id; 
} 
public String getUser_name() { 
    return user_name; 
} 
public void setUser_name(String user_name) { 
    this.user_name = user_name; 
} 
public String getUser_address() { 
    return user_address; 
} 
public void setUser_address(String user_address) { 
    this.user_address = user_address; 
} 
private String user_name; 
private String user_address; 
}

DataInsertion.java

package mypack; 

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

public class DataInsertion { 

public static void main(String[] args) { 
    new DataInsertion().insertInfo(); 

} 

public void insertInfo() 
{ 
Configuration con = new Configuration(); 
con.configure("hibernate.cfg.xml"); 
SessionFactory SF = con.buildSessionFactory(); 
Session session = SF.openSession(); 
DataProvider provider = new DataProvider(); 
provider.setUser_id(121); 
provider.setUser_name("Mehandi Hassan"); 
provider.setUser_address("Delhi"); 
Transaction TR = session.beginTransaction(); 
session.save(provider); 
System.out.println("Object save successfully"); 
TR.commit(); 
session.close(); 
SF.close(); 
} 
}

你有沒有結束標記'相同的DTD <冬眠配置>'？ – skozlov

是否有一個原因，你使用XML配置，而不是註釋？ – 2015-05-29 12:46:17

是兄弟我已關閉hibernate-configration文件 –

你需要註釋的DataProvider爲@Entity和@Id與

@Entity 公共類的DataProvider { @Id 的ID private int user_id; @Column private String user_name; @Column private String user_address;

...制定者干將 }

使用Hibernate 4.x的，你應該使用你需要在配置文件hibernate.cfg.xml中添加

<?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> 

     <property name="connection.driver_class">com.mysql.jdbc.Driver</property> 
     <property name="connection.url">jdbc:mysql://localhost:3306/hibernate</property> 
     <property name="connection.user">root</property> 
     <property name="connection.password">93Pb3gaNv0</property> 

     .... 
     .... 

    </session-factory> 
</hibernate-configuration>
