自定義注釋用法

Question

我想以以下方式定義自定義注釋並將其與Inject注釋一起使用。 如何訪問注入的bean中的注釋值？

注釋定義，

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface CustomAnnotation{
    String name();
}

訪問bean內的注釋屬性，

@Component
public class Processor {
    Would like to know the value "abc" in constructor/post-constructor. How to access name method here ?
}

測試用法（值“ abc”用於加載相應的配置並使Bean正常運行），

@Inject
@CustomAnnotation("abc")
Processor myProcessor;

public void test()
{
    myProcessor.process(); // myProcessor will behave based on value "abc"
}
