Is it possible to combine spring boot @Value with javax.validation.constraints?

I would like to validate values in application.properties. I use @Value to inject and @NotBlank to validate the method parameter in a class annotated with @Configuration.

createSslContext(
            @Value("#{systemProperties['javax.net.ssl.trustStore']}") 
            @NotBlank(message = "Truststore is needed") 
            String path)

I have included the hibernate-validator and the hibernate-validator-annotation-processor properties. Using Spring 2.2.0.RELEASE.

It doesn't work. The value is injected, but not validated. What am I missing?

Add @Validated to your configuration class.

@Configuration
@Validated
public class MyConfig {

    @Bean
    MyClass createSslContext(
        @Value("#{systemProperties['javax.net.ssl.trustStore']}")
        @NotBlank(message = "Truststore is needed") final
        String path) {

        ...
    }

}
