是否可以编写AOP注释？

Question

所以，我得到2个注释A和B。他们俩都做我班上必要的事情：

public class MyClass{

    @A
    @B(value="key")
    public void method(){

    }
}

是否可以将第三个注释C定义为两者的组合？所以最后我会得到：

public class MyClass{

    @C(value="key")
    public void method(){

    }
}

Answer 1

取决于您使用的库。例如春天做

@Documented
@Inherited
@SpringBootConfiguration
@EnableAutoConfiguration
@ComponentScan(excludeFilters = {
        @Filter(type = FilterType.CUSTOM, classes = TypeExcludeFilter.class),
        @Filter(type = FilterType.CUSTOM, classes = AutoConfigurationExcludeFilter.class) })
public @interface SpringBootApplication {

    /**
     * Exclude specific auto-configuration classes such that they will never be applied.
     * @return the classes to exclude
     */
    @AliasFor(annotation = EnableAutoConfiguration.class)
    Class<?>[] exclude() default {};

使用这种方法，您将拥有：

@ A@B公共@interface C {@AliasFor（注释= B.class）字符串值（）;}

Answer 2

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@A
@B
public @interface C {
    @AliasFor(annotation = B.class, attribute = "value")
    String value() default {};
}

让我知道是否可行。
