第一步：创建实体类News.java

package com.estar.hibernate.entity;

import java.util.Date;

/**

* 实体类

*

* @author Administrator

*

*/

public class News {
private Integer id;
private String author;
private String title;
private Date date;

public Date getDate() {
return date;
}

public void setDate(Date date) {
this.date = date;
}

public Integer getId() {
return id;
}

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

public String getAuthor() {
return author;
}

public void setAuthor(String author) {
this.author = author;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

public News(String author, String title, Date date) {
super();

this.author = author;
this.title = title;
this.date = date;
}

public News() {
super();
}

@Override
public String toString() {
return "News [author=" + author + ", data=" + date + ", id=" + id
+ ", title=" + title + "]";
}

}

第二步：导入Hibernate需要的包

antlr-2.7.7.jar

c3p0-0.9.2.1.jar

dom4j-1.6.1.jar

hibernate-c3p0-4.2.4.Final.jar

hibernate-commons-annotations-4.0.2.Final.jar

hibernate-core-4.2.4.Final.jar

hibernate-jpa-2.0-api-1.0.1.Final.jar

javassist-3.15.0-GA.jar

jboss-logging-3.1.0.GA.jar

jboss-transaction-api_1.1_spec-1.0.1.Final.jar

junit-4.7.jar

mchange-commons-java-0.2.3.4.jar

mysql-connector-java-5.1.7-bin.jar

第三步骤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">

<hibernate-configuration>
<session-factory>


<property name="connection.username">root</property>
<property name="connection.password">123456</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost/test</property>



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


<property name="show_sql">true</property>


<property name="format_sql">true</property>


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


<mapping resource="com/estar/hibernate/entity/News.hbm.xml"/>

</session-factory>

</hibernate-configuration>

第四步：News.hbm.xml映射文件

<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>

<class name="com.estar.hibernate.entity.News" table="NEWS">

<id name="id" type="java.lang.Integer">
<column name="ID" />

<generator class="native" />
</id>

<property name="title" type="java.lang.String" column="TITLE">
</property>

<property name="author" type="java.lang.String">
<column name="AUTHOR" />
</property>

<property name="date" type="java.util.Date">
<column name="DATE" />
</property>

</class>

</hibernate-mapping>
