Hibernate CFG文件

我是java和hibernate框架的新手,请问我是否必须为我拥有的每个表制作一个Hibernate cfg文件,或者仅此就足够了。现在我有了这个,它可以处理一个人表,现在,如果我还想使用一个新表(以我的情况为例),是否需要编写一个新文件并更改映射?

<?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">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="hibernate.connection.url">jdbc:mysql://localhost:3310/scheduler</property>
        <property name="hibernate.connection.username">root</property>
        <property name="hibernate.connection.password">blanked-out-as-this-is-s3cr3t</property>
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
        <property name="show_sql">true</property>
        <property name="hbm2ddl.auto">update</property>
        <mapping class="com.scheduler.backend.model.Person"></mapping>
    </session-factory>
</hibernate-configuration>

您只需要一个 cfg文件,如果您需要添加新表,只需将其发布为

class Event_Class {
  Flag_Play;
  Flag_Pause;
  Flag_Stop;
  Initialize() {
    this.Flag_Play = false;
    this.Flag_Pause = false;
    this.Flag_Stop = false;
  }
  Play() {
    this.Flag_Play = true;
    this.Flag_Pause = false;
    this.Flag_Stop = false;
  }
  Pause() {
    this.Flag_Play = false;
    this.Flag_Pause = true;
    this.Flag_Stop = false;
  }
  Stop(Simulation, PMSM) {
    this.Flag_Play = false;
    this.Flag_Pause = false;
    this.Flag_Stop = true;
    Simulation.Initialize();
    PMSM.Initialize();
  }
}

因此文件应如下所示:

<mapping class="com.scheduler.backend.model.NEW_MODEL"></mapping>
