@Value not working in web controller (but getProperty() does)

[llappall]

Hi,

I need to add a bunch of Properties backed in the DB at start up time.
To test the whole thing works, I started with this (the ds.username property below comes from catalina.properties. It's there just to verify I don't break anything):

public class PropertiesInitializer implements ApplicationContextInitializer<ConfigurableWebAppli cationContext> {
@Override
public void initialize(ConfigurableWebApplicationContext ctx) {
try {
props.put("hello", "goodbye");
MutablePropertySources propertySources = ctx.getEnvironment().getPropertySources();
propertySources.addFirst(new MapPropertySource("dbProps", props));
}
catch(Exception e) {
e.printStackTrace();
}
}


I have a @Controller and I'm doing this:
@Autowired
Environment env;
@Value( "${hello}" )
public String hello;
@Value( "${ds.username}" )
public String un;
...
System.out.println(hello + " " + un + " " + env.getProperty("hello") + " " + env.getProperty("ds.username"));

So, hello and un are "" but the env.getProperties actually return the right values.

Why?

Thanks

Please use [ code][/code ] tags when posting code, that way it remains readable...

Please post your configuration and actual controller code instead of snippets, hard to determine what (and if) there is something wrong.

Thanks for the 'code' tip. Wasn't sure how to do that.

As for the answer: I got a reply in StackOverflow. Someone said I needed to use the PropertySourcePlaceholderConfigurer for @Value to work. I implemented it, and I'm good.

Thanks
