## 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)`
