如何拦截Spring托管bean中定义的内部非Spring类的方法执行？
如何拦截Spring托管bean中定义的内部非Spring类的方法执行？
提问于 2017-10-28 20:09:58
我需要实现内部类的拦截器，外部类由Spring托管
@Component
@Scope("prototype")
public class Outer {
protected class Inner {
protected void methodToIntercept() {
}
}
}Outer.Inner.class可能有childs (也可能是匿名的)。重写的methodToIntercept()也应该被截获
文档非常简单：https://docs.spring.io/spring/docs/3.2.0.RELEASE/spring-framework-reference/htmlsingle/#aop-aj-ltw
根据文档，我按照以下方式配置了所有内容：
项目结构
-src
--main
---java
----temp
-----Config.java
-----MyAspect.java
-----Outer.java
-----SpringBean.java
--test
---resources
----META-INF
-----aop.xmlaop.xml
<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">
<aspectj>
<weaver>
<include within="temp.*"/>
</weaver>
<aspects>
<aspect name="temp.MyAspect"/>
</aspects>
</aspectj>Config.java
@Configuration
@EnableLoadTimeWeaving
@ComponentScan("temp")
@Lazy
public class Config {
}Outer.java
@Component
@Scope("prototype")
public class Outer {
@Component
public static class Inner {
public void methodToIntercept() {
}
}
}MyAspect.java
@Aspect
@Component
public class MyAspect {
@Autowired
private SpringBean springBean;
@Around("execution(* temp.Outer.Inner.methodToIntercept())")
public Object interceptor(ProceedingJoinPoint joinPoint) throws Throwable {
System.out.println("success");
return joinPoint.proceed();
}
}依赖关系

</dependencies>不幸的是，它并没有像我预期的那样工作
它应该与这样的配置一起工作吗？我错过了什么？
谢谢

尝试创建自定义注释并对方法进行注释。
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface ServiceLoggable {
}您的周围的@将如下所示
@Around("execution(* *(..)) && @annotation(com.company.core.log.ServiceLoggable)")
public Object logServiceMethods(ProceedingJoinPoint jp) throws Throwable {
