Hibernate(一)建立一个简单的Hibernate工程

Hibernate初步.

一.创建一个Maven工程

　　引入依赖

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.0.7.Final</version>
</dependency>


<dependency>
    <groupId>javax.transaction</groupId>
    <artifactId>jta</artifactId>
    <version>1.1</version>
</dependency>

　　编辑配置文件

<?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>
        <!--连接属性-->
        <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
        <property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property>
        <property name="connection.username">wy</property>
        <property name="connection.password">root</property>


        <!-- 数据库方言 -->
        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
        <!-- 连接池数量 -->
        <property name="connection.pool_size">10</property>
        <!-- 开启session与线程绑定 -->
        <property name="current_session_context_class">thread</property>

        <!-- 是否在控制台打印sql -->
        <property name="show_sql">true</property>
        <!-- 创建数据库的方式 -->
        <property name="hbm2ddl.auto">update</property>
        <property name="javax.persistence.validation.mode">none</property>
        <!--关联的映射文件-->
        <mapping resource="cn/hibernate/entity/Student.hbm.xml" />
       
    </session-factory>
</hibernate-configuration>

　　编辑实体类

package cn.hibernate.entity;

public class Student {
    private Integer id;
    private String name;


    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

　　编辑映射文件

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.hibernate.entity">

    <class name="Student" table="student" >

        <id name="id" column="id">
            <generator class="native"/>
        </id>
        <property name="name" column="name"></property>

    </class>
</hibernate-mapping>
