Evaluating spring @value annotation as primitive boolean

Question

I have a spring @configuration annotated class MappingsClientConfig with a boolean field as:

 @Value(\"${mappings.enabled:true}\")
    private boolean mappi         


        

Answer 1

This is how it was solved in our project, as the other answers didn't work for us. We were using spring batch, also.

main job config:

@Configuration
@EnableBatchProcessing
@PropertySource("classpath:application.properties")
public class MainJobConfiguration {
    @Autowired
    PipelineConfig config;

    @Bean
    public PipelineConfig pipelineConfig(){
        return new PipelineConfig();
    }

    // To resolve ${} in @Value
    @Bean
    public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    // job stuff ...
}

properties config loader:

public class PipelineConfig {
    @Value("${option}")
    private boolean option;
}

Note how the @Value is in the PipelineConfig, but the actual properties from which the option is loaded, is specified in the job class.
