注解

如何创建注解

• 添加元注解
  • @Target:注解添加的位置
  • @Retention：注解运行的时间
  • @Documented：是否记录为javadoc
  • @Inherited：子类是否可以继承父类的注解

@Target({ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Component
public @interface Controller {

	/**
	 * The value may indicate a suggestion for a logical component name,
	 * to be turned into a Spring bean in case of an autodetected component.
	 * @return the suggested component name, if any (or empty String otherwise)
	 */
	String value() default "";

}
