添加`module-info.java`后，Flyway在测试期间无法访问资源

标签： java flyway java-10 java-module

从Java 8升级到Java 10后，我设法使所有功能正常运行，但是在添加module-info.java之后，我遇到的问题之一是Flyway在运行Windows 10时无法访问SQL文件。从命令行进行测试。

启动应用程序或运行IntelliJ的测试（但我发现在IntelliJ上运行时，与模块相关的许多问题并没有变得显而易见）。使用mvn spring-boot:run启动应用程序可以正常工作，但是使用mvn package构建应用程序在测试任务中失败，出现以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.api.FlywayException: Unable to obtain input

我猜测模块系统阻止了对那些文件的访问，但是由于无法从IntelliJ运行该文件时对其进行复制，因此无法对其进行调试以获取更多详细信息。关于模块系统如何影响资源文件加载的任何想法？

我尝试添加：

opens tech.flexpoint.dashmanserver to spring.core;

可以帮助我的模块，但这没什么作用。

答案 0 :(得分：5)

您打开了tech.flexpoint.dashmanserver程序包，但是该程序包不在db/migration/V0002__enable_uuid.sql所在的位置。打开db.migration包应该可以解决问题。

模块是封装的，这意味着不允许其他代码（例如Flyway）查看其内部工作原理。实际上，所有.jar条目都是私有的，但类和打开包中的文件除外。

Class.getResource和Class.getResourceAsStream状态的文档：

  

命名模块中的资源受模块getResourceAsStream方法中指定的封装规则的约束，因此，当资源为非“ null”资源时，此方法返回.class对调用者的模块不开放的软件包。

The documentation for Module.getResourceAsStream解释了封装规则：

  

可以封装命名模块中的资源，以使其他模块中的代码无法定位该资源。能否确定资源的确定如下：

     
      
  • 如果资源名称以“ .class”结尾，则不会被封装。
    •   
  • 程序包名称是从资源名称派生的。如果程序包名称是模块中的程序包，则仅当程序包至少对调用方的模块打开时，该方法的调用方才能找到资源。如果该资源不在模块的包装中，则该资源不会被封装。
