Spring - 编译时的动态属性

时间:2015-06-22 09:26:04

标签: java spring maven compilation

我在几乎纯粹的基于XML的Spring中开发,我想切换到基于注释。但是我对动态属性有问题。

在基于XML的过程中,我定义了这样的属性:

<context:property-placeholder location="classpath:server-${coffee_feedback_env}.properties"/>

当我想编译它时,我可以这样做:mvn clean package -Dcoffee_feedback_env=dev

在这种情况下,选择了名为server-dev.properties的文件。

然而,基于注释的相同方法不起作用。当我像这样定义属性文件时:@PropertySource(value = { "classpath:server-${coffee_feedback_env}.properties" }),它确实以错误

结束

是否有类似的方法为不同的发行版定义不同的属性文件?

如何指出,eviroment变量应该传递给Tomcat,我将这行<Environment name="coffee_feedback_env" value="dev" type="java.lang.String" override="false"/>添加到tomcat/conf/context.xml并且它按预期工作。
