NoSuchMethodException：com.aspectj.in.spring.boot.aop.aspect.auditlog.interceptor.LoggingInterceptorAspect.aspectOf()

Question

我有一个使用 AspectJ 的代码。我使用编译时编织模式。在上下文初始化期间，出现错误。尽管在那之前一切正常。

注解


@Retention(RUNTIME)
@Target(METHOD)
@Documented
public @interface AuditAnnotation {

    public String value() default "";;
}

LoggingInterceptorAspect

@Aspect
public class LoggingInterceptorAspect {


    private LoggingService loggingService;

    @Autowired
    public LoggingInterceptorAspect(LoggingService loggingService) {
        this.loggingService = loggingService;
    }

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

@Pointcut("@annotation(com.aspectj.in.spring.boot.aop.aspect.auditlog.annotation.AuditAnnotation)")
    public void annotatedMethodCustom() {}

    @Before("annotatedMethodCustom() && privateMethod()")
    public void addCommandDetailsToMessage() throws Throwable {

        ZonedDateTime dateTime = ZonedDateTime.now(ZoneOffset.UTC);
        String message = String.format("User controller getUsers method called at %s", dateTime);

        System.out.println("+++++++++++++++++++++++++");
        loggingService.log(message);
    }
}

LoggingInterceptorConfig（这里报错。）

@Configuration
public class LoggingInterceptorConfig {

    @Bean
    public LoggingInterceptorAspect getAutowireCapableLoggingInterceptor() {

        return Aspects.aspectOf(LoggingInterceptorAspect.class);
    }
}

这一行有一个错误：

return Aspects.aspectOf(LoggingInterceptorAspect.class);
异常

在反射的帮助下，在LoggingInterceptorAspect.class中定义了所有public方法。但为什么 null returned?

也许有人知道为什么没有进行初始化LoggingInterceptorAspect.class

Answer 1

@Aspect
@Component
public class LoggingInterceptorAspect {

使用@Component，您在应用程序上下文中注册了一个 LoggingInterceptorAspect 类型的 bean。

    @Bean
    public LoggingInterceptorAspect getAutowireCapableLoggingInterceptor() {

这里 @Bean 您在应用程序上下文中再次注册了另一个类型为 LoggingInterceptorAspect 的 bean

当两个都是单例时，为什么要注册 2 个相同类型的 bean？

Answer 2

感谢 GitHub 上的 MCVE。访问它后，帮助我轻松识别您的问题如下：

您的动态 @annotation() 切入点非常广泛，针对所有包。我建议另外添加 within() 以限制方面范围。
为了将记录器自动注入方面，您希望使用 setter 而不是构造函数，因为 AspectJ 方面应该具有默认构造函数。
切入点表达式 privateMethod() && publicMethod() 永远不会匹配，因为一个方法不能同时是 public 和私有的。您想改用 ||。或者，如果您无论如何都想匹配两个切入点，则可以简单地省略两个切入点。还要小心，因为除了 public 和私有方法之外，还有受保护和包范围的方法，如果你只针对 public 和私有方法，你将被排除在外。

您的外观应该如下所示：

package com.aspectj.in.spring.boot.aop.aspect.auditlog.interceptor;

import com.aspectj.in.spring.boot.service.LoggingService;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.beans.factory.annotation.Autowired;

import java.time.ZoneOffset;
import java.time.ZonedDateTime;

@Aspect
public class LoggingInterceptorAspect {
    private LoggingService loggingService;

    @Autowired
    public void setLoggingService(LoggingService loggingService) {
        this.loggingService = loggingService;
    }

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

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

    @Pointcut("@annotation(com.aspectj.in.spring.boot.aop.aspect.auditlog.annotation.AuditAnnotation)")
    public void annotatedMethodCustom() {}

    @Pointcut("within(com.aspectj.in.spring.boot..*)")
    public void applicationScoped() {}


    @Before("annotatedMethodCustom() && applicationScoped()")
    //@Before("annotatedMethodCustom() && applicationScoped() && (privateMethod() || publicMethod())")
    public void addCommandDetailsToMessage(JoinPoint joinPoint) throws Throwable {
        ZonedDateTime dateTime = ZonedDateTime.now(ZoneOffset.UTC);
        String message = String.format("User controller getUsers method called at %s", dateTime);
        System.out.println("+++ " + joinPoint);
        loggingService.log(message);
    }
}

更新： 我忘了在未明确使用 execution() 的方面提及一个可能的问题，因为它们想匹配所有方法：使用 [=14= 时] 只有，你的目标是 call() 和 execution() 连接点，正如你在编译器日志中看到的那样：

[INFO] Join point 'method-call(java.util.List com.aspectj.in.spring.boot.controller.UserController.getUsersInternal())' in Type 'com.aspectj.in.spring.boot.controller.UserController' (UserController.java:26) advised by before advice from 'com.aspectj.in.spring.boot.aop.aspect.auditlog.interceptor.LoggingInterceptorAspect' (LoggingInterceptorAspect.java:37)
[INFO] Join point 'method-execution(java.util.List com.aspectj.in.spring.boot.controller.UserController.getUsersInternal())' in Type 'com.aspectj.in.spring.boot.controller.UserController' (UserController.java:32) advised by before advice from 'com.aspectj.in.spring.boot.aop.aspect.auditlog.interceptor.LoggingInterceptorAspect' (LoggingInterceptorAspect.java:37)
CLASSPATH component C:\Program Files\JetBrains\IntelliJ IDEA 2018.3\plugins\maven\lib\maven3\boot\plexus-classworlds.license: java.util.zip.ZipException: zip END header not found
[INFO] Join point 'method-execution(java.util.List com.aspectj.in.spring.boot.service.impl.DefaultUserService.getMockUsers())' in Type 'com.aspectj.in.spring.boot.service.impl.DefaultUserService' (DefaultUserService.java:34) advised by around advice from 'org.springframework.cache.aspectj.AnnotationCacheAspect' (spring-aspects-5.3.9.jar!AbstractCacheAspect.class:64(from AbstractCacheAspect.aj))

当省略 && (privateMethod() || publicMethod()) 条件时，这也会导致重复的运行时日志输出：

+++ call(List com.aspectj.in.spring.boot.controller.UserController.getUsersInternal())
2021-09-04 16:11:41.213  INFO 17948 --- [o-auto-1-exec-1] sample-spring-aspectj                    : User controller getUsers method called at 2021-09-04T14:11:41.210203700Z
+++ execution(List com.aspectj.in.spring.boot.controller.UserController.getUsersInternal())

为了避免这种情况，您应该添加一个通用的执行切入点：

@Before("annotatedMethodCustom() && applicationScoped() && execution(* *(..))")

NoSuchMethodException：com.aspectj.in.spring.boot.aop.aspect.auditlog.interceptor.LoggingInterceptorAspect.aspectOf()

NoSuchMethodException: com.aspectj.in.spring.boot.aop.aspect.auditlog.interceptor.LoggingInterceptorAspect.aspectOf()
