如何正确更改spring配置xml文件从Hibernate 3迁移到Hibernate 4？

分类: 技术问答 • 2022-07-01 13:31:13
问题描述：

我正在阅读“Pro Spring 3”一书，作者使用Hibernate 3作为应用程序。如何正确更改spring配置xml文件从Hibernate 3迁移到Hibernate 4？

本书的春天-config.xml中如下：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.1.xsd 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> 

    <jdbc:embedded-database id="dataSource" type="H2"> 
     <jdbc:script location="classpath:schema.sql"/> 
     <jdbc:script location="classpath:test-data.sql"/> 
    </jdbc:embedded-database> 

    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> 
     <property name="sessionFactory" ref="sessionFactory"/> 
    </bean>  

    <tx:annotation-driven/> 

    <context:component-scan base-package="com.apress.prospring3.ch9" /> 

    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> 
     <property name="dataSource" ref="dataSource"/> 
     <property name="packagesToScan" value="com.apress.prospring3.ch9.domain"/> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop> 
       <prop key="hibernate.max_fetch_depth">3</prop> 
       <prop key="hibernate.jdbc.fetch_size">50</prop> 
       <prop key="hibernate.jdbc.batch_size">10</prop> 
       <prop key="hibernate.show_sql">true</prop> 
      </props> 
     </property>   
    </bean> 

</beans>

我的实验，尝试使用Hibernate 4春天-config.xml中如下：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:context="http://www.springframework.org/schema/context" 
     xmlns:tx="http://www.springframework.org/schema/cache" 
     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd"> 
    <context:annotation-config /> 
    <context:component-scan base-package="foo.bar"/> 

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
     <property name="driverClassName"> 
      <value>${jdbc.driverClassName}</value> 
     </property> 
     <property name="url"> 
      <value>${jdbc.url}</value> 
     </property> 
     <property name="username"> 
      <value>${jdbc.username}</value> 
     </property> 
     <property name="password"> 
      <value>${jdbc.password}</value> 
     </property> 
    </bean> 

    <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
     <property name="sessionFactory" ref="sessionFactory"/> 
    </bean> 

    <tx:annotation-driven/> 

    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> 
     <property name="dataSource" ref="dataSource"/> 
     <property name="packagesToScan" value="foo.bar.domain"/> 
     <property name="hibernateProperties"> 
      <props> 
       <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 
       <prop key="hibernate.max_fetch_depth">3</prop> 
       <prop key="hibernate.jdbc.fetch_size">50</prop> 
       <prop key="hibernate.jdbc.batch_size">10</prop> 
       <prop key="hibernate.show_sql">true</prop> 
      </props> 
     </property> 
    </bean> 


    <context:property-placeholder location="jdbc.properties"/> 
</beans>

当我试图使用我自己的版本的spring-config.xml运行应用程序我得到以下错误：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.interceptor.CacheInterceptor#0': Cannot resolve reference to bean 'cacheManager' while setting bean property 'cacheManager'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'cacheManager' is defined

A我在这里做正确的代码转换？ 谢谢。

更新2：

SpringHibernateSample.java：

import foo.bar.dao.ContactDao; 
import foo.bar.domain.Contact; 
import org.springframework.context.support.GenericXmlApplicationContext; 

import java.util.List; 


public class SpringHibernateSample { 

    public static void main(String[] args) { 
     GenericXmlApplicationContext ctx = new GenericXmlApplicationContext("spring-config.xml"); 

     ContactDao contactDao = ctx.getBean("contactDao", ContactDao.class); 
     List<Contact> contacts = contactDao.findAll(); 
     listContacts(contacts); 
    } 

    private static void listContacts(List<Contact> contacts) 
    { 
     System.out.println(""); 
     System.out.println("Listing contacts without details:"); 

     for (Contact contact: contacts) 
     { 
      System.out.println(contact); 
      System.out.println(); 
     } 
    }

foo.bar包中的类是什么？ –

我有一个数据访问对象的dao软件包和一个普通域对象的域包。 – skiabox

这些bean中的一个是用@Cacheable注解的吗？ –

答

的问题是对xmnls:tx命名空间参考，如果你看看你的春天配置休眠4，你可以看到发送点至认为：http://www.springframework.org/schema/cache代替http://www.springframework.org/schema/tx

这意味着春天正在寻找一个cacheManager而不是transactionManager

将xmlns:tx="http://www.springframework.org/schema/cache"更改为xmlns:tx="http://www.springframework.org/schema/tx"在spring配置文件的beans标记中，它应该工作。

我的错当然是因为IntelliJ Idea提出了我的3个相同的tx：注解驱动的标签！ – skiabox

答

在你的堆栈跟踪您可以看到：

Error creating bean with name 'org.springframework.cache.interceptor.CacheInterceptor#0'

org.springfra mework.cache.interceptor包似乎与AOP相关联。所以这可能与您的标签有关

<tx:annotation-driven/>

尝试将其删除以查看是否仍有错误。

你也可以试试这个：

<tx:annotation-driven transaction-manager="transactionManager" order="1"/>

而在去年，直接从Spring和Hibernate得到librairies，有可能在你的librairies造成问题的一类。

您建议我删除哪个标签？ – skiabox
