java - Flyway添加 `module-info.java`后测试时无法访问资源

标签 java flyway java-10 java-module

升级到 Java 10(从 8)后，我设法让一切正常工作，但是在添加 module-info.java 之后，我遇到的问题之一是 Flyway 不能从命令行运行测试时访问 SQL 文件。

从 IntelliJ 工作启动应用程序或运行测试(但我发现许多与模块相关的问题在 IntelliJ 上运行时不会变得明显)。当使用 mvn spring-boot:run 启动应用程序时它工作正常，但是使用 mvn package 构建应用程序在测试任务中失败并出现此错误:

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
stream for resource: db/migration/V0002__enable_uuid.sql

我猜模块系统阻止了对这些文件的访问，但是因为我无法在从 IntelliJ 运行它时复制它，所以我无法调试它以获取更多详细信息。关于模块系统如何影响资源文件的加载有什么想法吗？

我尝试添加:

opens tech.flexpoint.dashmanserver to spring.core;

到我的模块，以防万一，但没有任何区别。

最佳答案

您打开了 tech.flexpoint.dashmanserver 包，但该包不在 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(如 Flyway)查看其内部工作原理。实际上，所有 .jar 条目都是私有(private)的，除了打开的包中的类和文件。

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

Resources in named modules are subject to the rules for encapsulation specified in the Module getResourceAsStream method and so this method returns null when the resource is a non-".class" resource in a package that is not open to the caller's module.

The documentation for Module.getResourceAsStream解释封装规则:

A resource in a named module may be encapsulated so that it cannot be located by code in other modules. Whether a resource can be located or not is determined as follows:

  • If the resource name ends with ".class" then it is not encapsulated.
  • A package name is derived from the resource name. If the package name is a package in the module then the resource can only be located by the caller of this method when the package is open to at least the caller's module. If the resource is not in a package in the module then the resource is not encapsulated.
