Spring Boot 如何避免在Sping Boot 应用程序中出现“类路径资源[...]不存在而无法打开”的情况？

我有一个小的spring Boot 应用程序，它application.properties在src/main/resources中提供了一个www.example.com-它工作起来很有魅力。用户现在应该能够配置更多的东西（2个凭据），所以我希望在classpath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。该应用程序与gradle spring boot任务bootDistZip一起分发。

@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，有一个“bin”和一个“lib”文件夹。我希望当我将配置放入这个目录并使用./bin/matrixregistration启动应用程序时，类路径应该包含“.”并找到配置。但它没有。配置文件在那里。
例外情况：

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

有人能告诉我如何配置该任务或我应该如何做才能让它工作？谢谢！
edit：with @PropertySource（“file：./matrixregistration.properties“）它可以工作。用户可以配置应用程序，在“.”中查找matrixregistration.properties

spring-boot

我也遇到了同样的问题，并通过“清洁构建”解决了它。

我也遇到过类似的问题，我认为你必须把绝对路径放在@PropertySource（“classpath：matrixregistration.config”）中。
例如：
@PropertySource（“classpath：path/from/src/matrixregistration.config”）
我希望它能帮助你。

当我的文件名为_时，我也遇到了同样的错误。删除文件名中的下划线为我修复。
我的文件名是my_file_name.csv，将其更改为my-file-name.csv可以工作。
