Spring Boot 2.1：类路径资源 [keystore.p12] 无法解析为 URL，因为它不存在

Question

我是 Spring Boot 和开发的新手。在 kotlin 和 gradle 中使用 Spring Boot 2。当我尝试附加 ssl 证书时出现类路径错误。Spring Boot 1.4解决方案：类路径资源 [] 无法解析为 URL，因为它不存在不起作用。

同时，我尝试复制解决方案并删除了 starter-data-jpa 的实现并使用了 starter-jdbc。但似乎没有任何效果。另一个解决方案也会引发相同的错误。

Application.property 文件

#spring.data.jpa.repositories.enabled=false



# Tell Spring Security (if used) to require requests over HTTPS
security.require-ssl=true

# The format used for the keystore
server.ssl.key-store-type=PKCS12
# The path to the keystore containing the certificate
server.ssl.key-store=./keystore.p12
# The password used to generate the certificate
server.ssl.key-store-password=
# The alias mapped to the certificate
server.ssl.key-alias=tomcat

我使用了 ./keystore 因为类路径不起作用。使用 ./ 解决它。但是当我更改 jar 位置并停止工作时。我不能将 keystore.p12 放在 build/libs/ 中与 jar 相同的位置。但我会喜欢 Kotlin 中的类路径解决方案。
