getClassLoader().getResourceAsStream(resource) 在 java 11 中返回 null

Question

我正在将 Spring Boot Java 项目从 openshift-jdk-8 迁移到 openshift-jdk-11。在 java-11 中，当项目在 openshift 云环境中部署为 docker 映像时，始终返回 null。在 Windows/本地环境中运行时，相同的代码运行良好。

getClassLoader().getResourceAsStream("mapper/myfile.xml")

从 bean-io 依赖加载文件

implementation("org.beanio:beanio:2.1.0")

我在这个 jar 的下面位置有文件。

BOOT-INF
 --classes
    --mapper/myfile.xml

遇到错误

任何解决此问题的建议

你可以试试 java.nio：

new String(Files.readAllBytes(Paths.get(absoluteFilePath)));
