3

我正在阅读“Pro Spring 3”一书，作者将 Hibernate 3 用于应用程序。

本书的 spring-config.xml 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"

            </props>
        </property>        
    </bean>

</beans>

我尝试使用 Hibernate 4 的实验性 spring-config.xml 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"

    <context:annotation-config />
    <context:component-scan base-package="foo.bar"/>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

        <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>

当我尝试使用我自己的 spring-config.xml 版本运行应用程序时，出现以下错误：

我在这里做正确的代码转换吗？谢谢你。

问题在于 的命名空间引用xmnls:tx，如果您查看 hibernate 4 的 spring 配置，您可以看到 tx 指向：http://www.springframework.org/schema/cache而不是http://www.springframework.org/schema/tx

这意味着spring正在寻找一个cacheManager而不是一个transactionManager

更改xmlns:tx="http://www.springframework.org/schema/cache"为xmlns:tx="http://www.springframework.org/schema/tx"spring 配置文件的 beans 标记，它应该可以工作。

在您的堆栈跟踪中，您可以看到：

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

org.springframework.cache.interceptor 包似乎与 AOP 相关联。所以它可能与你的标签有关 

<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"/>

最后，直接从 Spring 和 Hibernate 获取库，您的库中可能有一个类会导致问题。
