spring 配置sessionFactory_org.springframework.orm.hibernate3.annotation.anno-优快云博客

本文详细介绍了Spring框架中SessionFactory的不同配置方法，包括不使用dataSource直接引入hibernate.cfg.xml、使用注解方式以及通过packagesToScan扫描包的方式。每种配置方法都提供了具体的XML配置示例。

spring中sessionFactory的配置：

1.不用dataSource，引入hibernate.cfg.xml

applicationContext.xml代码：（org.springframework.orm.hibernate3.LocalSessionFactoryBean）

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
	<property name="configLocation">
		<value>classpath:hibernate.cfg.xml</value>
	</property>
</bean>

2.不使用hibernate.cfg.xml

*注解方式（ org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean）

<bean id="sessionFactory"
       class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
       <property name="dataSource" ref="dataSource" />
       <property name="annotatedClasses">
	     <list>
		<value>com.gc.model.User</value>
             </list>
       </property>
      <property name="hibernateProperties">
		<props>
			<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
			<prop key="hibernate.show_sql">true</prop>
		</props>
      </property>
</bean>

注解的Java代码：

package com.gc.model;

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

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.xml.bind.annotation.XmlTransient;

@Entity
public class User {

	private int id;
	private String username;
	private String password;
	private int age;
	private List<Product> products=new ArrayList<Product>();
	
	@Id
	@GeneratedValue
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	
	@OneToMany(mappedBy="creator")
	@XmlTransient
	public List<Product> getProducts() {
		return products;
	}
	public void setProducts(List<Product> products) {
		this.products = products;
	}
	
}

不使用注解：（org.springframework.orm.hibernate3.LocalSessionFactoryBean）

<bean id="sessionFactory"
	class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<!-- 依赖注入数据源，注入正是上面定义的dataSource -->
	<property name="dataSource" ref="dataSource" />
	<property name="mappingResources""><!-- mappingResouces属性用来列出全部映射文件 -->
	<list><!-- 以下用来列出Hibernate映射文件 -->
		<value>com/gc/model/User.hbm.xml</value>
	</list>
	</property>
 		<!-- 定义Hibernate的SessionFactory的属性 -->
	<property name="hibernateProperties">
		<props>
			<!-- 指定数据库方言 -->
			<prop key="hibernate.dialect">
				org.hibernate.dialect.MySQLInnoDBDialect</prop>
			<!-- 是否根据需要每次自动创建数据库 -->
			<prop key="hibernate.hbm2ddl.auto">update</prop>
			<!-- 显示Hibernate持久化操作所生成的SQL -->
			<prop key="hibernate.show_sql">true</prop>
			<!-- 将SQL脚本进行格式化后再输出 -->
			<prop key="hibernate.format_sql">true</prop>
		</props>
	</property>
</bean>

3.使用packagesToScan（org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean）

<bean id="sessionFactory"
	class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
	<property name="dataSource" ref="dataSource" />
	 <property name="packagesToScan">
	    <list>
		<value>com.gc.model</value>
	     </list>
	</property>
	<property name="hibernateProperties">
		<props>
			<prop key="hibernate.dialect">
				org.hibernate.dialect.MySQLDialect
			</prop>
			<prop key="hibernate.show_sql">true</prop>
		</props>
	</property>
</bean>
