java - 切换到 JPMS（Java 平台模块系统）时出现 Spring NoSuchBeanDefinitionException

Question

我正在尝试将一个大型项目迁移到 JPMS（Java 平台模块系统）。

它包含一些给我带来麻烦的 Spring 组件。我创建了一个测试仓库来演示这个问题。当我删除 module-info.java 文件时，它工作得很好，如TestControllerTest.java中的测试所示。但是，如果我添加 module-info.java 那么它会停止工作并出现以下异常：

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'RESTConfiguration': Unsatisfied dependency expressed through field 'fooAuthenticationProvider'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.spacemetric.spring.jpmstest.auth.FooAuthenticationProvider' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
at [e-mail]/org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:643)
at [e-mail]/org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:130)
at … 

堆栈跟踪似乎表明ApplicationContext无法找到@Autowired实现。我已经打开了整个模块进行深度反思。我高度未受教育的猜测是，这可能与类路径与模块路径有关，但我不知道该怎么做。

module-info.java 文件如下：

open module com.spacemetric.spring.jpmstest {       
    requires spring.core;
    requires spring.context;
    requires spring.beans;
    requires spring.security.config;
    requires spring.security.web;
    requires spring.webmvc;
    requires spring.security.core;
    requires javax.servlet.api;
    requires spring.web;
}

以下是 Eclipse 用来运行测试的命令行（根据要求）：

Answer 1

首先放入module-info.javain src/main/java，而不是 in src/test/java。我也将其稍微更改为：

module spring.jpms.test {
   requires spring.core;
   requires spring.context;
   requires spring.beans;
   requires spring.security.config;
   requires spring.security.web;
   requires spring.webmvc;
   requires spring.security.core;
   requires javax.servlet.api;
   requires spring.web;

   opens com.spacemetric.spring.jpmstest;

}

但无论如何，这只能“部分”解决，因为：

modules欢迎来到和spring（或一般的工具）的一个相当粗糙的现实。看看这里，人们有同样的问题。我发现的唯一可行的解​​决方案是：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>3.0.0-M5</version>
    <configuration>
        <useModulePath>false</useModulePath>
    </configuration>
</plugin>

这适用于mvn clean install（和junit5），我还没有尝试或玩过足够的intellij东西来使它工作。
