hibernate的demo

最近在學習ssh把一些小demo記錄下來以備日後查看
各位兄弟有什麼好的建議，那就請不要吝嗇，請多多指點。

java 代碼

package com.tyq.pojo;

public class User  implements java.io.Serializable {


    // Fields

     private int id;
     private String name;
     private Password password = null;


    public Password getPassword() {
        return password;
    }

    public void setPassword(Password password) {
        this.password = password;
    }

    /** default constructor */
    public User() {
    }


    // Property accessors

    public int getId() {
        return this.id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return this.name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

java 代碼

package com.tyq.pojo;



public class Password  implements java.io.Serializable {


    // Fields

     private int id;
     private String password;
     private User user = null;

    // Constructors

    /** default constructor */
    public Password() {
    }


    // Property accessors

    public int getId() {
        return this.id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getPassword() {
        return this.password;
    }

    public void setPassword(String password) {
        this.password = password;
    }


    public User getUser() {
        return user;
    }


    public void setUser(User user) {
        this.user = user;
    }
}

以上是兩個pojo類由於是學習用的就弄的簡單些把密碼和用戶名給分開，再次聲明這只是測試用真正的開發中這絕對是一bad smell
下面是對應的配置文件

xml 代碼

<!--User.hbm.xml-->
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
    Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
    <class name="com.tyq.pojo.User" table="user">
        <id name="id" type="java.lang.Integer">
            <column name="id" />
            <generator class="identity" />
        </id>
        <property name="name" type="java.lang.String">
            <column name="name" length="20" unique="true" />
        </property>
        <one-to-one name="password"
        class="com.tyq.pojo.Password"
        cascade="all"/>
    </class>
</hibernate-mapping>

xml 代碼

<1--Password.hbm.xml-->
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
    Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
    <class name="com.tyq.pojo.Password" table="password">
        <id name="id" type="java.lang.Integer">
            <column name="id" />
            <generator class="identity"></generator>
        </id>
        <property name="password" type="java.lang.String">
            <column name="password" length="40" not-null="true" unique="true" />
        </property>
        <one-to-one name="user"
        class="com.tyq.pojo.User"
        constrained="true"/>
    </class>
</hibernate-mapping>

下面就是hibernate 的配置文件拉

xml 代碼

<!--hibernate.cfg.xml-->
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<!-- Generated by MyEclipse Hibernate Tools.                   -->
<hibernate-configuration>

    <session-factory>
        <property name="myeclipse.connection.profile">
            com.jdbc.mysql.Driver
        </property>
        <property name="connection.url">
            jdbc:mysql://localhost:3306/system
        </property>
        <property name="connection.username">yourname</property>
        <property name="connection.password">yourpassword</property>
        <property name="connection.driver_class">
            com.mysql.jdbc.Driver
        </property>
        <property name="dialect">
            org.hibernate.dialect.MySQLDialect
        </property>
        <property name="show_sql">true</property>
        <mapping resource="com/tyq/pojo/User.hbm.xml" />
        <mapping resource="com/tyq/pojo/Password.hbm.xml" />

    </session-factory>

</hibernate-configuration>

下面是測試用類

java 代碼

import junit.framework.TestCase;

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

import com.tyq.pojo.Password;
import com.tyq.pojo.User;


public class TestHibernate extends TestCase {

    Session session = null;
    @Override
    protected void setUp() throws Exception {
        super.setUp();
        Configuration config = new Configuration().configure();
        SessionFactory factory = config.buildSessionFactory();
        session = factory.openSession();
    }

    @Override
    protected void tearDown() throws Exception {
        if(session != null)
        {
            session.close();
        }
        super.tearDown();
    }
    public void testSelect(){
        User user = new User();
        Password password = new Password();
        user.setName("lql");
        password.setPassword("tyq");
        user.setPassword(password);
        password.setUser(user);
        session.save(user);
        session.beginTransaction().commit();
    }


}

OK現在可以去數據庫裏看結果拉
