spring-boot - 如何在 Spring Boot 应用程序中避免 "class path resource [...] cannot be opened because it does not exist"？

Question

我有一个小的 Spring Boot 应用程序，它在 src/main/resources 中提供了一个 application.properties - 这就像一个魅力。用户现在应该能够配置更多内容(2 个凭据)，因此我期望类路径中有一个名为“matrixregistration.config”的文件。不幸的是，无论在哪里都找不到这个文件。该应用程序通过 gradle spring boot 任务 bootDistZip 进行分发。

@Configuration
@PropertySource("classpath:matrixregistration.config")
@Validated
public class MatrixRegistrationConfiguration {

    private String sharedSecret;
    private String registrationPassword;
...

我的分发包位于服务器上的/home/matrix/matrixregistration-boot 上，有一个“bin”和一个“lib”文件夹。我希望当我将配置放入此目录并使用 ./bin/matrixregistration 启动应用程序时，类路径应包含“.”并找到配置。但事实并非如此。配置文件就在那里。

异常(exception):

matrix@myhost:~/matrixregistration-boot$ ./bin/matrixregistration

有人可以告诉我如何配置该任务或者我应该如何让它工作吗？谢谢!

编辑:与@PropertySource("文件:./matrixregistration.properties")有用。用户可以配置在“.”中查找的应用程序。对于矩阵注册.properties

我遇到了同样的问题，并通过“干净构建”解决了它。
