本文详细介绍了Hibernate框架的基础设置，包括所需Jar包、配置文件编写、POJO类定义及基本的增删改查操作，并针对常见错误提供了相应的解决方案。

1 Hibernate 需要的jar包

asm-3.3.jar

cglib-2.2.2

commons-beanutils

commons-collections-3.1

commons-lang3-3.3.1

commons-logging

dom4j-1.6

hibernate-3.2

mysql-connector-java-5.1.5-bin

odmg-3.0

2Hibernate.cfg.xml文件的配置代码

<?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.url">
jdbc:mysql://localhost:3306/test?
</property>
<property name="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<property name="connection.password">root</property>
<property name="connection.driver_class">
com.mysql.jdbc.Driver
</property>

<property name="show_sql">true</property>
<mapping resource="com/lin/po/Person.hbm.xml" />

</session-factory>

</hibernate-configuration>

3 po 类的代码

package com.lin.po;

public class Person {
public Person() {
super();
// TODO Auto-generated constructor stub
}
private float id;
private String name;
public float getId() {
return id;
}
public void setId(float id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

}

4 测试的代码

package com.lin.test;

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

import com.lin.po.Person;

public class TestHBM {
public static void main(String[] args) {
Person p =new Person();
p.setId(1.0f);
p.setName("linda");
add(p);

}
public static void add(Person p){
Transaction t =null;
try {
Configuration c =new Configuration().configure();
SessionFactory sf =c.buildSessionFactory();
Session s =sf.openSession();
s.beginTransaction();
s.save(p);
s.getTransaction().commit();
s.close();
sf.close();
System.out.println(c);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}

}
