1，利用配置檔案類生成表

1）先建一個類，get和set方法

@Data
public class Salary {
    private Integer workcode;
    private String uname;
    private String dept;
    private BigInteger baseSalary;
    private Long extract;
    private Long leav;
    private Long sick;
    private Long pk;


    @Override
public String toString() {
        return 
 
"Salary{" +
                "workcode='" + workcode + '\'' +
                ", uname='" + uname + '\'' +
                ", dept='" + dept + '\'' +
                ", baseSalary=" + baseSalary +
                ", extract=" + extract +
                ", leav=" + leav +
                ", sick=" + sick 
 
+
                ", pk=" + pk +
                '}';
    }

3）配置檔案

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPEhibernate-configurationPUBLIC"-//Hibernate/Hibernate Configuration DTD//EN""http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
  <session-factory
 
>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
    <property name="connection.url">jdbc:mysql://localhost:3306/salary</property>

    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="connection.username">root</property>
    <property name="connection.password">12345678</property>

    <property name="hbm2ddl.auto">update</property>

    <mapping resource="com/oracle/bean/Salary.hbm.xml"/>
    <!-- DB schema will be updated if needed -->




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

<property name="hbm2ddl.auto">update</property>沒有表就建立表，沒有欄位就建立欄位，只能新增不能修改和刪除

create是建立一個表，

validate只能校驗

2）配置Salary.hbm.xml

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPEhibernate-mappingPUBLIC"-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>

    <class name="com.oracle.bean.Salary" table="salary" schema="salary">
        <id name="workcode" column="workcode">
         <generator class="uuid"></generator>主鍵生成策略如uuid是String型別

        </id>
        <property name="uname" column="uname"></property>
        <property name="dept" column="dept"></property>
        <property name="baseSalary" column="base_salary"></property>
        <property name="extract" column="extract"></property>
        <property name="leav" column="leav"></property>
        <property name="sick" column="sick"></property>
        <property name="pk" column="pk"></property>
    </class>
</hibernate-mapping>

二，用程式碼生成表

 public static void main(String[] args) {
      createby3610();
    }

//5.1.0版本
public void  createby510()
    {
        Configuration config = new Configuration().configure();
        StandardServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
                .configure().build();
        Metadata metadata = new MetadataSources(serviceRegistry)
                .buildMetadata();
        SchemaExport schemaExport = new SchemaExport();
        schemaExport.create(EnumSet.of(TargetType.DATABASE), metadata);
    }

    //3.6.0版本
public static void createby3610()
    {
//        Configuration cfg=new Configuration();
//        cfg.configure();
//        SchemaExport export=new SchemaExport(cfg);
//        //script 表示是否打印出指令碼
//        //export 表是否執行生成資料表
//        export.create(true,true);
}

}

三，集合對映

一個人有多個別名

@Data
public class User {
    private  String usid;
    private String usname;
     private List<String> otherNames;



}

User.hbm.xml把檔案對映到Hibernate.cfg.xml中

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPEhibernate-mappingPUBLIC"-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.oracle.bean">

    <class name="User" table="user" >
        <id name="usid" >
            <generator class="uuid"></generator>

        </id>
        <property name="usname" ></property>
        <list name="otherNames" table="othername" >
            <key column="nameid"></key><!--主表和子表之間關聯的欄位-->
<list-index column="nameindex"></list-index><!--排序的欄位-->
<element column="othername" type="java.lang.String"></element><!--真正存放資料的欄位-->
</list>
    </class>
</hibernate-mapping>

package com.oracle.core;

import com.oracle.bean.User;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import java.util.ArrayList;
import java.util.List;

public class CreateListData {
    private Session session;
    private SessionFactory sessionFactory;

@Before
public void begin(){
    Configuration cfg=new Configuration();
    cfg.configure();
    SessionFactory sessionFactory = cfg.buildSessionFactory();
    session=  sessionFactory.openSession();
    session.beginTransaction();

}

@Test
public void main() {
    //新增別名
List<String> namesList=new ArrayList<String>();
        namesList.add("333");
        namesList.add("444");
        namesList.add("555");
        User user=new User();
        user.setOtherNames(namesList);
        user.setUsname("aaa");
       session.save(user);
    }


    @Test
public void edit(){
    //在原有的基礎上再新增幾個別名用update，先查詢再新增
User user=session.get(User.class,"8a8aac94635ea6c801635ea6d3160000");
   List<String> nameList=new ArrayList<>();
   nameList.add("123");
        nameList.add("12345");
        nameList.add("123456");
        user.setOtherNames(nameList);
        session.update(user);

    }

    @After
public void end(){
    session.getTransaction().commit();
    session.close();
    sessionFactory.close();


    }


}
