使用 Postgresql 将 jHipster 部署到 AWS 时spring.datasource.CONFIGUR

Question

>我已经用Tomcat和Postgresql RDS设置了一个Elastic Beanstalk实例。 如果我在本地构建和部署，一切正常，我没有任何问题。 如果我将其部署到 AWS Elastic Beanstalk 环境，应用程序将无法启动，并且我在 Spring ConfigurationPropertiesBindingPostProcessor.java 文件中收到错误。

我的配置文件：

spring:
    profiles:
        active: prod
    devtools:
        restart:
            enabled: false
        livereload:
            enabled: false
    datasource:
        driver-class-name: org.postgresql.ds.PGSimpleDataSource
        url: jdbc:postgresql://arc.redacted.us-east-1.rds.amazonaws.com:5432/arc
        username: redacted
        password: redacted

以下是日志的相关部分：

和

Caused by: java.lang.IllegalArgumentException: Illegal group reference

同样，如果我部署本地，这工作正常。 我已确保否则可以连接到 RDS 数据库。

还有人遇到过这个吗？

您需要添加数据库的名称：

datasource:
    driver-class-name: org.postgresql.ds.PGSimpleDataSource
    url: jdbc:postgresql://arc.redacted.us-east-1.rds.amazonaws.com:5432/arc
    name: arc
    username: redacted
    password: redacted
