Spring NoSuchBeanDefinitionException when switching to JPMS (Java Platform Module System)

问题

我正在尝试将一个大型项目迁移到JPMS（Java平台模块系统）。

其中包含一些Spring组件，它们给我带来了一些麻烦。
我创建了一个test repo来演示这个问题。当我删除module-info.java文件时，它可以正常工作，就像TestControllerTest.java中的测试所示。然而，如果我添加module-info.java，那么它就停止工作，并显示以下异常：

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 spring.beans@5.2.6.RELEASE/org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:643)
at spring.beans@5.2.6.RELEASE/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。我已经为深度反射打开了整个模块。我非常不确定，但我猜想这可能与classpath与modulepath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用于运行测试的命令行（如请求所示）：

I am trying to migrate a large project to JPMS (Java Platform Module System).

It contains some Spring components that are giving me some trouble.
I have created a test repo to demonstrate the issue. When I remove the module-info.java file it works just fine as shown by the test in TestControllerTest.java. However, if I add the module-info.java then it stops working with the following exception:

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 spring.beans@5.2.6.RELEASE/org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:643)
at spring.beans@5.2.6.RELEASE/org.springframework.beans.factory.annotation.InjectionMetadata.inject(InjectionMetadata.java:130)
at …

The stack trace seems to indicate that the ApplicationContext is unable to find the @Autowired implementation. I have opened the entire module for deep reflection. My highly uneducated guess is that this might be related to the classpath versus modulepath but I am at a loss for what to do about it.

The module-info.java file is as follows:

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;
}

The following is the command line used by Eclipse to run the test (as requested):

答案1

得分: 1

首先，将 module-info.java 放在 src/main/java 中，而不是 src/test/java 中。此外，我稍微修改了它：

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;
}

但是，无论如何，这只解决了部分问题，因为：

欢迎来到“模块”和“Spring”（或一般工具）的相当原始的现实。在这里可以看到有相同问题的人们。我找到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（以及 junit5），我还没有尝试过或充分使用 intellij 使其工作。

英文:

First of all put the module-info.java in src/main/java, not in src/test/java. Also I have slightly changed it to:

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;

}

But anyway, this solves only "partially" because:

Welcome to a rather crude reality of modules and spring (or tools in general). Have a look here, where people have the same problems. The only viable solution I found is to do :

&lt;plugin&gt;
	&lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
	&lt;artifactId&gt;maven-surefire-plugin&lt;/artifactId&gt;
	&lt;version&gt;3.0.0-M5&lt;/version&gt;
	&lt;configuration&gt;
		&lt;useModulePath&gt;false&lt;/useModulePath&gt;
	&lt;/configuration&gt;
&lt;/plugin&gt;

This works with mvn clean install (and junit5), I haven't tried or played enough with intellij to make it work.
