无法在创建SpringLiquibase bean的静态工厂方法中使用占位符

spring

无法在创建SpringLiquibase bean的静态工厂方法中使用占位符,spring,liquibase,applicationcontext,Spring,Liquibase,Applicationcontext,Spring 3.1.0，Liquibase 2.0.5在Glassfish 2.1.1上运行-我从一位早已离开的同事那里继承了这个applicationContext.xml，它以如下方式构造SpringLiquibase bean： <bean id="liquibaseConfiguratore" factory-method="createLiquibaseBean" class="com.whatever.LiquibaseFactory"> <constru

Spring 3.1.0，Liquibase 2.0.5在Glassfish 2.1.1上运行-我从一位早已离开的同事那里继承了这个applicationContext.xml，它以如下方式构造SpringLiquibase bean：

<bean id="liquibaseConfiguratore" factory-method="createLiquibaseBean" class="com.whatever.LiquibaseFactory">
    <constructor-arg name="dataSource" ref="dataSourceConfiguratore"/>
    <constructor-arg name="changeLog" value="classpath:liquibase/configuratore-db-changelog.xml"/>
    <constructor-arg name="propFileName" value="/opt/whatever/ec_properties.properties"/>
</bean>
现在我需要参数化changeLog值，以便我的bean声明变成：

<bean id="liquibaseConfiguratore" factory-method="createLiquibaseBean" class="com.whatever.LiquibaseFactory"> 
    <constructor-arg name="dataSource" ref="dataSourceConfiguratore"/>
    <constructor-arg name="changeLog" value="${tgo.liquibase.changelog.filename}"/>
    <constructor-arg name="propFileName" value="/opt/whatever/ec_properties.properties"/>
</bean>
读了这篇文章后，我将原始字符串放入属性文件中

tgo.liquibase.changelog.filename=classpath:liquibase/configuratore-db-changelog.xml
并将道具声明为：

<context:property-placeholder location="file:///opt/whatever/custom_properties.properties" />
显然，当XML中有一个普通字符串时，就会找到解析器。在我放置占位符的那一刻，解析器就不存在了。但看起来占位符解析正确，至少在屏幕上是这样

我尝试了一些变化：

  • 将文件：/absolute/path/to/configuratore-db-changelog.xml放入属性中
  • 将classpath*：liquibase/configuratore-db-changelog.xml放入属性中
  • 将属性“index=0,1,2”而不是“name”放在tag constructor.arg中
但问题仍然存在

如何使用占位符指定changeLog参数？

以下是完整的堆栈跟踪：
