## Annotation Type Lazy

-     @Target(value={TYPE,METHOD,CONSTRUCTOR,PARAMETER,FIELD})
       @Retention(value=RUNTIME)
       @Documented
      public @interface Lazy

  Indicates whether a bean is to be lazily initialized.

  May be used on any class directly or indirectly annotated with `@Component` or on methods annotated with `@Bean`.

  If this annotation is not present on a `@Component` or `@Bean` definition, eager initialization will occur. If present and set to `true`, the `@Bean` or `@Component` will not be initialized until referenced by another bean or explicitly retrieved from the enclosing `BeanFactory`. If present and set to `false`, the bean will be instantiated on startup by bean factories that perform eager initialization of singletons.

  If Lazy is present on a `@Configuration` class, this indicates that all `@Bean` methods within that `@Configuration` should be lazily initialized. If `@Lazy` is present and false on a `@Bean` method within a `@Lazy`-annotated `@Configuration` class, this indicates overriding the 'default lazy' behavior and that the bean should be eagerly initialized.

  In addition to its role for component initialization, this annotation may also be placed on injection points marked with `Autowired` or `Inject`: In that context, it leads to the creation of a lazy-resolution proxy for all affected dependencies, as an alternative to using `ObjectFactory` or `Provider`.
