组合注解的意思就是一个注解中包含多个注解。在springmvc 的@RestController中，你就可发现.
@Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) @Documented @Controller @ResponseBody public @interface RestController { /** * 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 * @since 4.0.1 */ String value() default ""; }
