在Tomcat中没有用Spring配置AspectJ LTW [英] AspectJ LTW not getting configured with Spring in Tomcat

问题描述

我遵循了以下春季文档中给出的步骤: https://docs.spring.io/spring/docs/4.3.14.RELEASE/spring-framework-reference/html/aop.html#aop-aj-ltw

I have followed the steps given in the following spring docs: https://docs.spring.io/spring/docs/4.3.14.RELEASE/spring-framework-reference/html/aop.html#aop-aj-ltw

我的项目是一个带有诸如此类模块的整体:

My project is a monolith with modules as such :

ApplicationService. 子模块m2和父级m1.(m1对m2有依赖性)

ApplicationService in module m1. Child module m2 with parent m1.(m1 has a dependency on m2)

aop.xml文件如下:

aop.xml file in m1/WebContent/META-INF/aop.xml as follows :

<!DOCTYPE aspectj PUBLIC "-//AspectJ//DTD//EN" "http://www.eclipse.org/aspectj/dtd/aspectj.dtd">

<aspectj>    
    <weaver>
        <!-- only weave classes in our application-specific packages -->
        <include within="m2.*"/>
    </weaver>

<aspects>
    <!-- weave in just this aspect -->
    <aspect name="m2.security.FieldPermissionAspect"/>
</aspects>

m1/src/main/webapp/WEB-INF中的Application-context.xml文件如下:

Application-context.xml file in m1/src/main/webapp/WEB-INF as follows :

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

...

<mvc:annotation-driven />
<aop:aspectj-autoproxy />
<task:annotation-driven />
<!-- this switches on the load-time weaving -->
<context:load-time-weaver weaver-class="org.springframework.instrument.classloading.tomcat.TomcatLoadTimeWeaver"/>

我在m2.security中的方面如下:

My aspect in m2.security is as follows:

package m2.security;


import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;


@Aspect
@Component
public class FieldPermissionAspect {


    @Pointcut("execution(public * *(..))")
    public void combinedPointcut() {}

    @Around("combinedPointcut()")
    public void aroundMapper(ProceedingJoinPoint joinPoint) {
        ...
    }

    @Around("cflow(combinedPointcut())")
    public void aroundSetter(ProceedingJoinPoint joinPoint) {
        ...
    }
}

m2中pom.xml中的AspectJ依赖项:

AspectJ dependencies in pom.xml in m2:

<dependencies>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>1.8.7</version>
        <scope>runtime</scope>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.aspectj/aspectjrt -->
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>1.8.7</version>
    </dependency>

</dependencies>

在tomcat环境中运行它时，出现以下错误:

When I run it in tomcat environment, I get the following error :

Caused by: org.aspectj.weaver.tools.UnsupportedPointcutPrimitiveException: Pointcut expression 'cflow(combinedPointcut())' contains unsupported pointcut primitive 'cflow'

我认为这是因为spring在我的方面仍在使用Spring AOP而不是AspectJ.我在这里想念什么?

I think it's because spring is still using Spring AOP instead of AspectJ in my aspect. What am I missing here?

推荐答案

如果要使用AspectJ LTW而不是Spring AOP，则不应使用Spring AOP配置.所以请摆脱<aop:aspectj-autoproxy />.尽管名称是关于Spring AOP，而不是AspectJ. AspectJ不使用任何代理.

If you want to use AspectJ LTW instead of Spring AOP, you should not use Spring AOP configuration. so please get rid of <aop:aspectj-autoproxy />. Despite the name it is about Spring AOP, not AspectJ. AspectJ does not use any proxies.

关于您的错误消息，...

As for your error message, ...

Caused by: org.aspectj.weaver.tools.UnsupportedPointcutPrimitiveException:
  Pointcut expression 'cflow(combinedPointcut())'
  contains unsupported pointcut primitive 'cflow'

...因为您仍在使用Spring AOP而发生，所以没有使用AspectJ LTW.因此，您遇到了配置问题.如果您使用以下容器启动容器，它会起作用吗?

... it occurs because you are still using Spring AOP, AspectJ LTW is not used. So you are having a configuration issue. Does it work if you start your container with

-javaagent:/path/to/aspectjweaver.jar

在Java命令行上?

最后但并非最不重要的一点，就像我在您的上一个问题中已经说过3倍一样，请提供一个MCVE ，那么我可以分析您的问题.除了推测您在此处提供的信息外，我真的无能为力.因此，请按照我的要求做，并帮助我为您提供帮助.谢谢.

Last, but not least, like I said 3x already in your previous question, please provide an MCVE on GitHub, then I can analyse your problem. I really cannot do more than speculate with the bits of information provided by you here. So please do what I asked you to and help me to help you. Thanks.
