[SOLVED] Spring 3.0.5 doesn't evaluate @Value annotation from properties

Spring 3.0.5 doesn't evaluate @Value annotation from properties

Trying to auto-wire properties to a bean in Spring 3.0.5.RELEASE, I'm using:

config.properties:
```
username=myusername
```

main-components.xml:

<context:property-placeholder location="classpath:config.properties" />

MyClass:

@Service
public class MyClass {

    @Value("${username}")
    private String username;
    ...
}

As a result, username gets set to literally "${username}", so the expression doesn't get parsed. My other auto-wired dependencies on this class get set, and Spring doesn't throw any exception. I also tried to add @Autowired but it didn't help.

If I parse properties to a separate bean and then use @Autowired + @Qualifier, it works:

<bean id="username" class="java.lang.String">
    <constructor-arg value="${username}"/>
</bean>

Any ideas how to use just @Value? Maybe I need to include some Spring dependency that I haven't? Thank you

Found what the issue was. Copy/paste from comments:

Are you sure you have <context:property-placeholder> in the same application context as your MyClass bean (not in the parent context)? – axtavt

You're right. I moved <context:property-placeholder> from the context defined by the ContextLoaderListener to the servlet context. Now my values get parsed. Thanks a lot! - alex
