java - 如何将带有自定义 .properties 文件的 Spring Boot 应用程序部署到 AWS ElasticBeanstalk？

Question

我有一个使用不同环境属性的 Spring Boot 应用程序。根据选定的环境，它从位于 ./resources 的 application-{dev/stag/prod}.properties 文件中获取所需的数据。当通过 InteliJ 在本地运行以及运行创建的 .jar 文件(使用带有 bootJar 的 Gradle 创建)时，一切正常。

我已经创建了一个 AWS ElasticBeanstalk 应用程序。在该应用程序中，我创建了一个 Java 环境并在那里部署了 .jar 文件。部署时，我在日志中看到以下错误:

似乎 AWS ElasticBeanstalk 无法读取 application-dev.properties 文件中的值。

这是我的 application-dev.properties 文件的样子:

spring.datasource.hikari.connectionTimeout=20000
spring.datasource.hikari.maximumPoolSize=5
spring.datasource.url=jdbc:postgresql://{REDACTED}
spring.datasource.username={REDACTED}
spring.datasource.password={REDACTED}
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults=false
app.message=Hello from dev properties

我已经尝试将环境特定属性移动到主 application.properties 文件并创建一个 .jar。但这也不起作用。

接下来我可以尝试什么？

您的 Spring Boot 应用程序似乎无法连接到 PostgreSQL 数据库。我建议你 dubbel 检查用户名和密码。如果您启用了防火墙，请检查必须连接到数据库的服务器是否在白名单中。
