Spring，Hibernate与嵌入式derby-Jetty自动重新部署数据库连接问题

时间：2016-05-10 06:59:51

标签： java hibernate spring-mvc derby embedded-jetty

我正在运行一个带有嵌入式derby Db的spring hibernate应用程序，并使用auto重新部署在jetty上运行它。现在进行自动重新部署时出现数据库连接错误：

addEventListener

现在我的问题是如何在重新部署时关闭连接，以便它可以创建一个新的连接，还是可以使用相同的连接？

答案 0 :(得分：0)

Harinder，

我认为你需要编辑一些代码。

读取错误消息..

  1. 目录D：\ aa \ branches \ dev \ saas \ aaSaas已存在。
  2. 更改架构<prop key="hibernate.default_schema">aaSaas</prop>

    3. derby文件夹中的delate文件夹（aaSaas）

            <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.DerbyDialect</prop> 
            <prop key="hibernate.default_schema">test</prop>
            <prop key="hibernate.connection.pool_size">4</prop>
            <prop key="hibernate.connection.shutdown">true</prop>
            <prop key="hibernate.show_sql">true</prop> 
            <prop key="hibernate.hbm2ddl.auto">create</prop><!--delete all entity after create entity  -->
        </props>

    嗯...

    数据源

     <bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource"> 
    <property name="driverClass" value="org.apache.derby.jdbc.ClientDriver"></property> 
    <property name="username" value="user"></property> <property name="password" 
    value="1234"></property> <property name="url" value="jdbc:derby://localhost:1527/aaSaas;create=true"></property> 
    </bean>

    我使用JPA和Derby .. 在其他情况下。

    嗯...祝你好运
