我需要实现内部类的拦截器,外部类由Spring管理
@Component
@Scope("prototype")
public class Outer {
protected class Inner {
protected void methodToIntercept() {
}
}
}
Outer.Inner.class
可能有孩子(也是匿名的)。 Overriden methodToIntercept()
也应该被拦截
文档很简单: 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.xml
aop.xml文件
<!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();
}
}

不幸的是,它无法正常工作
它是否适用于此类配置?我错过了什么?
由于
答案 0 :(得分:0)
尝试创建自定义注释并注释方法。
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface ServiceLoggable {
}
@Around 将如下所示
@Around("execution(* *(..)) && @annotation(com.company.core.log.ServiceLoggable)")
public Object logServiceMethods(ProceedingJoinPoint jp) throws Throwable {
...
}
