Spring application context : access web.xml context-params?
提问by Ashika Umanga Umagiliya
Greetings ,
问候 ，
Is there any way to get values from web.xml context-param into Spring context?
有没有办法将 web.xml 上下文参数中的值获取到 Spring 上下文中？
For example I define the value in web.xml as :
例如，我将 web.xml 中的值定义为：
<context-param>
<param-name>compass-index</param-name>
<param-value>file:///home/compass/index</param-value>
</context-param>
And I want to assign that value to the bean-property as:
我想将该值分配给 bean 属性：
<bean ...>
<props>
<prop key="compass.engine.connection">
${from web.xml context-param?}
</prop>
</props>
</bean>
Thanks in advance?
提前致谢？
