突然之间我使用Spring和Hibernate的webapp已停止连接到Apache Derby数据库。
我想知道是否有人可以提出原因？
我的应用使用Spring 4.0.2和Hibernate 4.3.5。属于该项目的derby.jar和derbyClient.jar版本取自Java JDK 1.8.0，我使用Apache Derby 10.10.1.1。 Apache Tomcat 8.0.3.0是我的服务器。
我的项目dispatcherservlet的Hibernate详细信息如下：
<!-- Hibernate DataSource. -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.apache.derby.jdbc.EmbeddedDriver" />
<property name="url" value="jdbc:derby://localhost:1527/Library" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>
<!-- Hibernate SessionFactory. -->
<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.DerbyTenSixDialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
<!-- What to do with the database schema. -->
<prop key="hbm2ddl.auto">update</prop>
<!-- validate: validate the schema, makes no changes to the database.
update: update the schema.
create: creates the schema, destroying previous data.
create-drop: drop the schema at the end of the session. -->
</props>
</property>
<property name="packagesToScan">
<list>
<value>registration_spring_hibernate.model</value>
</list>
</property>
</bean>
<!-- Hibernate TransactionManagment. -->
<tx:annotation-driven />
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
完整的错误日志如下：

答案 0 :(得分：1)
经过长时间讨论聊天，这里是答案，我刚刚发布了新的xml：
<!-- Hibernate DataSource. -->
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<!-- property name="driverClassName" value="org.apache.derby.jdbc.ClientDriver" /-->
<property name="driverClassName" value="org.apache.derby.jdbc.EmbeddedDriver" />
<property name="url" value="jdbc:derby://localhost:1527/Library" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>
<!-- Hibernate Interceptors. -->
<bean id="serverInterceptor" class="library.interceptor.ServerInterceptor" />
<!-- Hibernate SessionFactory. -->
<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.DerbyDialect</prop-->
<prop key="hibernate.dialect">org.hibernate.dialect.DerbyTenSixDialect</prop>
<prop key="hibernate.show_sql">false</prop>
也不要忘记使用非通用的接口。
