aspectj 编译时编织 - ajc$perSingletonInstance 为 null

Question

我的目标是在我的代码库中实现编译时编织，并发现了 AspectJ Maven 插件 (https://dev-aspectj.github.io/aspectj-maven-plugin/)。

aspectj.version = 1.9.21
maven-compiler.version = 3.11.0
java.version = 21

我做了以下修改：

在

dependencies

部分添加了以下代码：

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>${aspectj.version}</version>
</dependency>

在

<plugins>

部分包含以下代码：

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler.version}</version>
    <executions>
        <execution>
            <id>default-compile</id>
            <configuration>
                <compilerArguments>
                    <d>${project.build.directory}/unwoven-classes</d>
                </compilerArguments>
            </configuration>
        </execution>
    </executions>
</plugin>
<plugin>
    <groupId>dev.aspectj</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.13.1</version>
    <configuration>
        <complianceLevel>${java.version}</complianceLevel>
        <showWeaveInfo>true</showWeaveInfo>
        <forceAjcCompile>true</forceAjcCompile>
        <sources/>
        <weaveDirectories>
            <weaveDirectory>${project.build.directory}/unwoven-classes</weaveDirectory>
        </weaveDirectories>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>compile</goal>
            </goals>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjtools</artifactId>
            <version>${aspectj.version}</version>
        </dependency>
    </dependencies>
</plugin>

由于Lombok和AspectJ之间的兼容性问题，我最初编译为

unwoven-classes

，然后再继续

target/classes

。运行

mvn clean compile

会导致使用

[INFO] Join point...

成功构建。但是，在应用程序启动过程中，我遇到以下错误：

Caused by: org.aspectj.lang.NoAspectBoundException: Exception while initializing com.xyz.apirest.authorization.EnsureFromMonolith: java.lang.NoSuchMethodError: com.xyz.apirest.authorization.EnsureFromMonolith: method 'void <init>()' not found     at com.xyz.apirest.authorization.EnsureFromMonolith.aspectOf(EnsureFromMonolith.java:1)     at com.xyz.apirest.v1.internal.workflows.InternalDisbursementController.<clinit>(InternalDisbursementController.java:1)     ... 124 common frames omitted Caused by: java.lang.NoSuchMethodError: com.xyz.apirest.authorization.EnsureFromMonolith: method 'void <init>()' not found     at com.xyz.apirest.authorization.EnsureFromMonolith.ajc$postClinit(EnsureFromMonolith.java:1)     at com.xyz.apirest.authorization.EnsureFromMonolith.<clinit>(EnsureFromMonolith.java:1)     ... 125 common frames omitted

相关代码片段如下：

@Aspect
@Component
@RequiredArgsConstructor
public class EnsureFromMonolith {
    private final AuthenticationProfile authenticationProfile;
    private final XYZJwtAuthenticationConfig xyzJwtAuthenticationConfig;
    protected final Logger logger = LoggerFactory.getLogger(EnsureFromMonolith.class);

    @Around(value = "(execution(public * *(..)) && within(@com.xyz.apirest.authorization.RequireFromMonolith *)) || @annotation(com.xyz.apirest.authorization.RequireFromMonolith)")
    public Object ensureFromMonolith(ProceedingJoinPoint joinPoint) throws Throwable {
        if (authenticationProfile.getAid() == null) {
            return ResponseEntity.status(HttpStatus.NOT_FOUND).build();
        } else if (!validateProfile(authenticationProfile, xyzJwtAuthenticationConfig.getMonolithAuthorizedClientId())) {
            return ResponseEntity.status(HttpStatus.NOT_FOUND).build();
        }

        return joinPoint.proceed();
    }

    public static boolean validateProfile(AuthenticationProfile authenticationProfile, String monolithClientId) {
        return authenticationProfile.getAid().equals(monolithClientId);
    }
}

我已经尝试了AspectJ 不适用于编译时编织和如何使用maven构建aspectj项目？中推荐的解决方案，但没有成功。

我的目标是让应用程序成功启动，AspectJ 按预期运行。`

由于使用了 Spring 的基于代理的 AOP，该代码不起作用，该 AOP 在将 @Component 注释与 Spring 的 AOP 设置一起使用时启用。这种类型的 AOP 仅支持 Spring bean 的公共方法。
