使用Hibernate配置Spring。創建名稱為'usersDao'的bean時出錯：通過字段'sessionFactory'表示的不滿意依賴性

Question

我正在嘗試使用Hibernate 5配置Spring4。做了一個谷歌研究，但沒有幫助。 我正在使用JUnit測試啟動我的應用程序，只是為了查看Hibernate是否可以正常工作。

Error creating bean with name 'usersDao': Unsatisfied dependency expressed through field 'sessionFactory': Error creating bean with name 'sessionFactory' defined in class path resource [ConfigTest/datasource.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/boot/MetadataSources;)V; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [ConfigTest/datasource.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.hibernate.cfg.Configuration.<init>(Lorg/hibernate/boot/MetadataSources;)V

這是我的datasource.xml

<?xml version="1.0" encoding="UTF-8"?>

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

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

            <property name="driverClassName" value="${jdbc.driver}"></property>
            <property name="url" value="${jdbc.url}"></property>
            <property name="password" value="${jdbc.password}"></property>
            <property name="username" value="${jdbc.username}"></property>
        </bean>

        <bean id="sessionFactory"
            class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
            <property name="dataSource" ref="dataSource"></property>
            <property name="hibernateProperties">
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>

                </props>
            </property>
            <property name="packagesToScan">
                <list>
                    <value>DAO</value>
                </list>
            </property>
        </bean>

    </beans>

</beans>

另外，當我使用Hibernate 4時，我也會遇到錯誤：

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'offersDao': Injection of autowired dependencies failed; nested exception is java.lang.NoClassDefFoundError: org/hibernate/cache/spi/RegionFactory

但我確實在該地址設置了RegionFactory： 在此處輸入圖片描述

提前致謝！

Answer 1

看來packagesToScan屬性需要一個數組 。

就您而言，我想它看起來像這樣...

<property name="packagesToScan">
    <array>
        <value>DAO</value>
    </array>
</property>

也許只是...

<property name="packagesToScan" value="DAO" />

Answer 2

問題在於版本的兼容性。 所以我使用了Spring 4.0.3.RELEASE和Hibernate 4.3.5.Final，錯誤消失了。

我也有一個錯誤：找不到當前會話。 因此，我對事務bean進行了修改：

<bean id="transactionManager"
            class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"></property>
        </bean>
        <tx:annotation-driven />
