How do I configure a controller bean?

how to configure properties for mvc spring bean controller?

• Is there a special way for doing this? What i got is: config.properties with param.key=value web.xml with ContextLoaderListener that reads the configuration pages-servlet.xml that defines servlet beans. What I want is to configure one of the beans in pages-servlet.xml with param.key. I'm using <property name="myField" value="${param.key}"/> in the xml but I see that the field is configured with ${param.key} instead of 'value'. What is the right way to configure the bean? Ok, I solved it by importing application context file that defines configuration bean into pages-servlet.xml. It works, but seems very wrong.

• Answer:

  Property placeholder is what you want. <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <context:property-placeholder location="classpath:/config.properties" /> <bean id="mybean" class="..."> <property name="xxx" value="${prop.value}" /> </bean> </beans>
