Activating Spring Profile active JVM arguments in GWT hosted mode
提问by Aravind A
I have a spring profile configuration as shown below
我有一个弹簧配置文件，如下所示
<beans profile="dev">
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${db.driverClassName}" />
<property name="jdbcUrl" value="dfgdfg" />
<property name="user" value="${db.username}" />
<property name="password" value="${db.password}" />
</bean>
</beans>
<beans profile="prod">
<jee:jndi-lookup id="dataSource" jndi-name="jdbc/Test"/>
</beans>
I am trying to make one of this active via the VM argument -Dspring.profiles.active="dev". This works in Tomcat and so does the context-paramroute in Hosted mode via the gwt-maven-plugin but I can't get the VM arguments to work . I tried mvn -Dspring.profiles.active="dev" gwt:runalso tried to pass -Dspring.profiles.active="dev"via the VM arguments under the JRE tab in run configurations along with the goal gwt:run. I also tried the environment tab and even -Dspring.profiles.active=devbut the NoSuchBeanDefinitionExceptiondoesn't budge . Is this because of the limited capability of the embedded server ?
我试图通过 VM 参数激活其中之一-Dspring.profiles.active="dev"。这在 Tomcat 中有效，context-param通过 gwt-maven-plugin 在托管模式下的路由也是如此，但我无法让 VM 参数工作。我mvn -Dspring.profiles.active="dev" gwt:run还尝试-Dspring.profiles.active="dev"通过运行配置中 JRE 选项卡下的 VM 参数以及目标传递gwt:run。我也尝试了环境选项卡，甚至-Dspring.profiles.active=dev但NoSuchBeanDefinitionException没有让步。这是因为嵌入式服务器的能力有限吗？

No, simply gwt:maven plugin is kind of strange and it doesn't pass system properties to the launched JVM instance, and the only way to pass parameters is to put it into <extraJvmArgs>in plugin configuration e.g. in your case you have to add following to the configuration tag of gwt plugin:
不，只是 gwt:maven 插件有点奇怪，它不会将系统属性传递给启动的 JVM 实例，传递参数的唯一方法是将其放入<extraJvmArgs>插件配置中，例如在您的情况下，您必须添加以下内容gwt插件的配置标签：
<extraJvmArgs>-Dspring.profiles.active=dev</extraJvmArgs>
<extraJvmArgs>-Dspring.profiles.active=dev</extraJvmArgs>
God knows why this works only this way, I wish there were some other normal way.
天知道为什么这只能以这种方式工作，我希望有其他一些正常的方式。
