我在应用程序上下文中使用Liquibase版本3.3.2。
<bean id="liquibase" class="liquibase.integration.spring.SpringLiquibase">
<property name="dataSource" ref="writeDataSource" />
<property name="changeLog" value="classpath:sql/liquibase.xml" />
<property name="contexts" value="default" />
</bean>
<bean id="writeDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="url" value="jdbc:google:mysql://url" />
<property name="driverClassName" value="com.mysql.jdbc.GoogleDriver" />
<property name="username" value="****" />
<property name="password" value="****" />
</bean>
在Google App Engine上运行它会引发以下错误。似乎Liquibase无法在Google应用引擎上获取数据库锁定。这是GAE或我的代码端的问题。请帮忙。
