我使用
Spring-Liquibase来执行登台数据库所需的任何迁移.
applicationContext.xml看起来像
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.yahoo.comma"/>
<bean id="liquibase" class="liquibase.integration.spring.SpringLiquibase">
<property name="dataSource" ref="dataSource"/>
<property name="changeLog" value="classpath:liquibase/changelog.xml"/>
<property name="defaultSchema" value="pryme_dev"/>
</bean>
</beans>
当我部署war文件时,我看到日志中的错误为

问题
– 为什么在已填充数据库并且数据库中存在DATABASECHANGELOG文件时应用所有更改集？
– 我该如何解决这个问题？
谢谢
解决方法
问题通常是因为每个changeSet的唯一标识符的一部分是changelog文件的路径.它看起来像目前被视为“liquibase / 2014 / 1-1.xml”.
如果你运行select * from databasechangelog,其中id =’05192014.1525’数据库中已有的路径是什么？
