Spring @Value is not resolving to value from property file

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();
}

In my case, static fields will not be injected.

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

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

for Sprig-boot User both PropertyPlaceholderConfigurer and the new PropertySourcesPlaceholderConfigurer added in Spring 3.1. so it's straightforward to access properties file. just inject

Note: Make sure your property must not be Static

@Value("${key.value1}")
private String value;
