You can load the properties using java.util.Properties (or commons-configuration) in a ServletContextListener's contextInitialized(..) method.
register the listener with <listener> in web.xml
You then store the Properties into the ServletContext (you can get it from the event) (ctx.setAttribute("properties", properties)
then access the properties using ${applicationScope.properties.propName} (as BalusC noted, applicationScope is optional)
Update:
Initially I thought spring had some ready-to-use facility for that, but it turns out it's not exactly the case. You have two options:
this article explains something similar to my suggestion above, but using spring's PropertyPlaceholderConfigurer
this answer and this answer allow you to expose all your beans, including a PropertyPlaceholderConfigurer to the servlet context.
第二种方案
PropertyPlaceholderConfigurer can only parse placeholders in Spring configuration (XML or annotations). Is very common in Spring applications use a Properties bean. You can access it from your view this way (assuming you are using InternalResourceViewResolver): <bean id="properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean"> <property name="locations"> <list><value>classpath:config.properties</value></list> </property> </bean> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> <property name="exposedContextBeanNames"> <list><value>properties</value></list> </property> </bean> Then, in your JSP, you can use ${properties.myProperty} or ${properties['my.property']}.
