First: I'm using Spring 3.0
I have a problem when configuring my controller class. The controller uses a web service which I want to define the endpoint address using a .properties file.
@Controller
public class SupportController {
@Value("#{url.webservice}")
private String wsEndpoint;
...
In my application context xml-file, I've defined this:
<context:property-placeholder location="/WEB-INF/*.properties" />
I've been reading the documentation, trying different approaches (like adding prefix systemProperties. ),but I keep getting an error message telling me that it doesn't exist.
Field or property 'url' cannot be found on object of type 'org.springframework.beans.factory.config.BeanExpressionContext'
Ok. I've figured it out.
Now, in the controller:
@Value("#{settings['url.webservice']")
Then in the context configuration I have this "helper bean":
<util:properties id="settings"
location="/WEB-INF/supportweb.properties"></util:properties>
This should work, too:
@Value("${url.webservice}")
private String wsEndpoint;
I have this configuration and it works fine:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:application.properties</value>
</list>
</property>
</bean>
and I iniejct the property in this way
@Value("${root.log.level}")
private String prop;
the field is correctly initialized to "DEBUG" value.
you should check that the
<context:property-placeholder location="/WEB-INF/*.properties" />
is defined in webmvc-config.xml where you create instances of the @Controllers
