在Tomcat中未使用Spring配置AspectJ LTW

我遵循了以下spring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

我的项目是带有以下模块的整体：

模块m1中的ApplicationService。具有父级m1的子级模块m2。（m1与m2有依赖关系）

m1 / WebContent / META-INF / aop.xml中的aop.xml文件如下：

<!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：

<?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"

<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：

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：

<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：

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？

回答：

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。

至于您的错误消息，…

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

…之所以发生，是因为您仍在使用Spring AOP，所以没有使用AspectJ LTW。因此，您遇到配置问题。如果您使用以下命令启动容器，是否可行

-javaagent:/path/to/aspectjweaver.jar

在Java命令行上？

最后但并非最不重要的一点，就像我在上一个问题中已经说过3x一样，请在GitHub上提供一个MCVE，这样我就可以分析您的问题了。除了推测您在此处提供的信息外，我真的不能做其他事情。因此，请按照我的要求做，并帮助我为您提供帮助。谢谢。
