Spring @Value is not resolving to value from property file

Question

I\'ve had this working in some other project before, I am just re-doing the same thing but for some reason it\'s not working. The Spring @Value is not reading f

Answer 1

In my case I was missing the curly braces. I had @Value("foo.bar") String value instead of the correct form @Value("${foo.bar}") String value

Answer 2

I also found the reason @value was not working is, @value requires PropertySourcesPlaceholderConfigurer instead of a PropertyPlaceholderConfigurer. i did the same changes and it worked for me, i am using spring 4.0.3 release. I configured this using below code in my configuration file -

@Bean 
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}

Answer 3

Have a read of pedjaradenkovic's comment.

Further to the link he provides, the reason this isn't working is that @Value processing requires a PropertySourcesPlaceholderConfigurer instead of a PropertyPlaceholderConfigurer.

Answer 4

In my case, static fields will not be injected.

Answer 5

Problem is due to problem in my applicationContext.xml vs spring-servlet.xml - it was scoping issue between the beans.

pedjaradenkovic kindly pointed me to an existing resource: Spring @Value annotation in @Controller class not evaluating to value inside properties file and Spring 3.0.5 doesn't evaluate @Value annotation from properties

Answer 6

I was using spring boot, and for me upgrading the version from 1.4.0.RELEASE to 1.5.6.RELEASE solved this issue.
