我正在使用spring和hibernate与mysql db进行配置。
我的we.xml文件具有以下代码：
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/classes/applicationcontext.xml</param-value> </context-param> <session-config> <session-timeout> 30 </session-timeout> </session-config> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
我的applicationcontext.xml文件具有以下导入：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans default-autowire="autodetect"> <import resource="spring-config/spring-common-applicationContext.xml"/> <import resource="spring-config/spring-db-applicationContext.xml"/> <import resource="spring-config/spring-dao-applicationContext.xml"/> <import resource="spring-config/spring-processor-applicationContext.xml"/> <import resource="spring-config/spring-security-processor-applicationContext.xml"/> <import resource="spring-config/spring-service-applicationContext.xml"/> <import resource="spring-config/spring-security-service-applicationContext.xml"/> </beans>
我的spring-db-applicationContext.xml具有以下代码：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans default-autowire="autodetect"> <!-- Hibernate session factory --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <constructor-arg index="0"> <value>${driverClassName}</value> </constructor-arg> <constructor-arg index="1"> <value>${url}</value> </constructor-arg> <constructor-arg index="2"> <value>${username}</value> </constructor-arg> <constructor-arg index="3"> <value>${password}</value> </constructor-arg> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="dataSource"/> </property> <property name="configLocation"> <value>WEB-INF/classes/hibernate.cfg.xml</value> </property> <property name="configurationClass"> <value>org.hibernate.cfg.AnnotationConfiguration</value> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${dialect}</prop> <prop key="hibernate.show_sql">true</prop> <!--<prop key="hibernate.hbm2ddl.auto">create</prop>--> </props> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory"> <ref bean="sessionFactory"/> </property> </bean> <bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"> <property name="transactionManager" ref="transactionManager"/> <property name="transactionAttributeSource"> <value> com.sufalam.mailserver.business.service.IUserProcessor.*=PROPAGATION_REQUIRED,-java.lang.Exception </value> </property> </bean> </beans>
我已经包括适当的库。现在在运行项目时，出现以下错误：

谁能解决我的sessionFactory bean出错的问题？
提前致谢…
Spring告诉您确切的问题是什么，您只需要阅读日志和嵌套的错误消息：
设置bean属性“ sessionFactory”时无法解析对bean“ sessionFactory”的引用；嵌套的异常是org.springframework.beans.factory.BeanCurrentlyInCreationException： 创建名称为’sessionFactory’的bean时出错：FactoryBean（当前正在创建中）从getObject返回null
Google进行的一些搜索表明，该错误消息通常是循环依赖的结果，并且还导致了建议default- autowire="detect"从您的<beans>元素中删除邮件列表。
default- autowire="detect"
<beans>
