使用AOP處理註解時出現error Type referred to is not an annotation type:xxx

今天本想通過AOP來處理添加註解的介面,結果丟擲了error Type referred to is not an annotation type:xxx(註解名)的異常,原來需要將註解作為處理方法的一個引數傳遞進來,並且引數名字要和@annotation中的名字一樣,不過我在寫例子的時候沒有寫成引數也成功了,可能是有哪裡還沒弄清楚,不過暫時這個解決方案是可行的。
package com.aurora.annotation; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface MyAnnotation { String name() default ""; }
package com.aurora.annotation; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.springframework.stereotype.Component; @Aspect @Component public class AnnotationUtil { @Around(value = "execution(public * com.aurora..*.*(..)) && @annotation(myAnnotation) ") public Object dealAnnotation(ProceedingJoinPoint joinPoint, MyAnnotation myAnnotation) throws Throwable { System.out.println("aop"); Object response = joinPoint.proceed(); return response; } }
