使用 Java 模块时 Spring `superinterface check failed`（对于 Axon Framework Spring Boot 应用程序）

Question

我目前正在试验 Spring Boot、Axon 框架和 java 模块（使用 JDK 17）。

我创建了一个 repo 来说明这个问题： here

问题是应用程序没有启动，我得到如下异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'accountViewProjection' defined in file [C:\workspace\axon\_issue_replication_repos\axon-module-error\axon-example-app\build\classes\java\main\io\github\vab2048\axon\example_bug\app\query\account\AccountViewProjection.class]: Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Could not generate CGLIB subclass of class io.github.vab2048.axon.example_bug.app.query.account.AccountViewProjection: Common causes of this problem include using a final class or a non-visible class; nested exception is org.springframework.cglib.core.CodeGenerationException: java.lang.IllegalAccessError-->superinterface check failed: class io.github.vab2048.axon.example_bug.app.query.account.AccountViewProjection$$EnhancerBySpringCGLIB$$159eee6a (in module io.github.vab2048.axon.example_bug.app) cannot access class org.springframework.aop.framework.Advised (in unnamed module @0x732d0d24) because module io.github.vab2048.axon.example_bug.app does not read unnamed module @0x732d0d24

有问题的代码似乎在io.github.vab2048.axon.example_bug.app.query.account.AccountViewProjection中：

    @QueryHandler
    public AccountView getAccount(GetAccountView query) {
        log.debug("Handling: {}", query);
        return repository.findById(query.id()).orElseThrow();
    }

它是 Axon 注释@QueryHandler导致它（您可以通过将其注释掉来验证这一点，然后一切正常）。 这很奇怪，因为其他 Axon 注释都不会导致此问题。 包本身在module-info.java文件中导出和打开。

我究竟做错了什么？ 我知道可能会添加命令行参数来解决此问题，但不确定到底要使用什么（理想情况下我根本不必提供任何命令行参数）。

Answer 1

我有点怀疑将其发布为答案，但无论如何我都会这样做。

您是否尝试过从组合中删除 Spring AOP？ 似乎 Spring AOP 正在制作一些导致IllegalAccessError的内部类，而不是 Axon Framework。

如果这解决了这个问题，我敢打赌 Spring AOP 需要做一些事情来完成这项工作。 可悲的是，这不是我的强项，所以我必须调查什么样的设置（如果有的话）会在这个角度有所帮助。
