Annotation Type StepScope

@Scope(value="step",
       proxyMode=TARGET_CLASS)
@Retention(value=RUNTIME)
@Documented
public @interface StepScope

Convenient annotation for step scoped beans that defaults the proxy mode, so that it doesn't have to be specified explicitly on every bean definition. Use this on any @Bean that needs to inject @Values from the step context, and any bean that needs to share a lifecycle with a step execution (e.g. an ItemStream). E.g.

 @Bean
 @StepScope
 protected Callable<String> value(@Value("#{stepExecution.stepName}")
 final String value) {
        return new SimpleCallable(value);
 }
 

Marking a @Bean as @StepScope is equivalent to marking it as @Scope(value="step", proxyMode=TARGET_CLASS)
