使用mysql，但不能插入到數據庫

Question

我有一個名爲lablab的表名爲table，所以我的程序是註冊時的註冊，它將保存數據庫中的userName，fullName，birthDay，password和age。我的數據庫有fullName，userName，passWord，birthDay和age的列。我的程序運行但不能插入數據庫。

這裏是我的映射：

<hibernate-mapping> 
<class name="hello.model" table="table" schema="lablab"> 
<id name="id" column="ID" type="int"> 
<generator class="native"/> 
</id> 
<property name="fullName" column="fullName" type="string"/> 
<property name="userName" column="userName" type="string"/> 
<property name="passWord" column="passWord" type="string"/> 
<property name="birthDay" column="birthDay" type="string"/> 
<property name="age" column="age" type="int"/> 
</class> 
</hibernate-mapping> 

這是我cfg.xml中

<hibernate-configuration> 

    <session-factory> 

    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> 

    <property name="hibernate.connection.username">root</property> 

    <property name="hibernate.connection.password">root</property> 

    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> 

    <property 
    name="hibernate.connection.url">jdbc:mysql://localhost:3306/lablab</property> 

    <mapping resource="hibernate.hbm.xml"/> 

    </session-factory> 

    </hibernate-configuration> 

這裏是我的java類

package hello; 

import com.opensymphony.xwork2.ActionSupport; 
import org.hibernate.HibernateException; 
import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import org.hibernate.Transaction; 
    import org.hibernate.boot.registry.StandardServiceRegistryBuilder; 
    import org.hibernate.cfg.Configuration; 

public class model extends ActionSupport{ 
private String fullName, passWord, userName, birthDay, yearX, userLogin, passLogin; 
private int age, year, yearN; 
private static SessionFactory factory; 

public String getFullName() { 
    return fullName; 
} 

public void setFullName(String fullName) { 
    this.fullName = fullName; 
} 

public String getPassWord() { 
    return passWord; 
} 

public void setPassWord(String passWord) { 
    this.passWord = passWord; 
} 

public String getUserName() { 
    return userName; 
} 

public void setUserName(String userName) { 
    this.userName = userName; 
} 

public String getBirthDay() { 
    return birthDay; 
} 

public void setBirthDay(String birthDay) { 
    this.birthDay = birthDay; 
} 
public int getAge() { 
    return age; 
} 

public void setAge(int age) { 
    this.age = age; 
} 

public String getUserLogin() { 
    return userLogin; 
} 

public void setUserLogin(String userLogin) { 
    this.userLogin = userLogin; 
} 

public String getPassLogin() { 
    return passLogin; 
} 

public void setPassLogin(String passLogin) { 
    this.passLogin = passLogin; 
} 

public String register() throws Exception { 
    try 
     { 
     Configuration configuration = new Configuration().configure(); 
     StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder(). 
     applySettings(configuration.getProperties()); 
     factory = configuration.buildSessionFactory(builder.build()); 
     } 
     catch (HibernateException ex) 
     { 
     System.err.println("Failed to create sessionFactory object." + ex); 
     throw new ExceptionInInitializerError(ex); 
     } 
    addUser(fullName, userName, passWord, birthDay, age); 
    String success ="success"; 
    return success; 
} 

private Integer addUser(String fullName, String userName, String passWord, String birthDay, int age) { 
Session session = factory.openSession(); 
    Transaction tx = null; 
    Integer uID = null; 
    try{ 
    tx = session.beginTransaction(); 
    User item = new User(fullName, userName, passWord, birthDay, age) {}; 
    uID = (Integer) session.save(item); 
    tx.commit(); 
    }catch (HibernateException e) { 
    if (tx!=null) tx.rollback(); 
    e.printStackTrace(); 
    }finally { 
    session.close(); 
    } 
    return uID; 
} 

}

這裏是我的用戶類別

class User { 

private String fullName, userName, passWord, birthDay; 
private int age; 
public User(){} 


public User(String fullName, String userName, String passWord, String birthDay, int age){ 
this.fullName = fullName; 
this.userName = userName; 
this.passWord = passWord; 
this.birthDay = birthDay; 
this.age = age; 
} 

public String getFullName() { 
    return fullName; 
} 

public void setFullName(String fullName) { 
    this.fullName = fullName; 
} 

public String getUserName() { 
    return userName; 
} 

public void setUserName(String userName) { 
    this.userName = userName; 
} 

public String getPassWord() { 
    return passWord; 
} 

public void setPassWord(String passWord) { 
    this.passWord = passWord; 
} 

public String getBirthDay() { 
    return birthDay; 
} 

public void setBirthDay(String birthDay) { 
    this.birthDay = birthDay; 
} 

public int getAge() { 
    return age; 
} 

public void setAge(int age) { 
    this.age = age; 
}

如果你正在使用Hibernate的5，你應該通過這種方式創建SessionFactory：

factory = new Configuration().configure().buildSessionFactory(); 

這是一個不正確的方法：

Configuration configuration = new Configuration().configure(); 
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder(). 
applySettings(configuration.getProperties()); 
factory = configuration.buildSessionFactory(builder.build());
