Tomcat + Spring和环境变量

Question

In a Spring file I have:

   <bean id="propertyConfigurer" class="org.myapp.MyConfigurator">
        <property name="locations">
        <list>
                       <value>classpath:configuration-${env}.properties</value>
        </list>
    </property>
</bean>

the ${env} variable is defined in maven's profile. But when I run from eclipse the application in tomcat 6 (published) it doesn't look in maven. So how can I set the variable for Tomcat?

Thanks

Answer 1

在Eclipse中添加系统变量：转到Run - > Run Configurations - > Tomcat Select Arguments选项卡并添加到VM参数-Denv=blabla

Answer 2

要在tomcat context.xml中定义可在spring中使用的变量，请将此行添加到context.xml的右侧上下文中。

<Parameter name="env" value="ABCDEFG"  override="false"/>

Tarlog solution can be solve your problem but only inside eclipse, if you remove your server definition from eclipse you lost the definition and you need to add it again each time you change your IDE or delete the server definition.

So better way create a shell or bat file(like runServer.sh/.bat) according to your environment and add this parameter to the JAVA_OPTS variable so this variable called when catalina.sh/.bat is running (startup.sh/.bat called catalina script inside it). You can use this approach at your local, test and prod environment.

Windows: runServer.bat

set JAVA_OPTS="-Dvariable=value"
tomcat/bin/startup.bat

Linux: runServer.sh

export JAVA_OPTS="-Dvariable=value"
tomcat/bin/startup.sh
