【中文标题】无法将 AWS-Postgres 服务器与带有 heroku 托管的 Spring Boot 应用程序连接起来【英文标题】：Fail to connect AWS-Postgres server with spring boot application with heroku hosting 【发布时间】：2018-11-19 05:14:19 【问题描述】：我在 Heroku 上托管 spring-boot 应用程序并添加 Heroku-postgres 的附加组件。他们为我提供了托管在 AWS-EC2 上的数据库凭证。我正在尝试将我的 Spring Boot 应用程序与由 Heroku 提供并托管在 AWS-EC2 上的数据库连接，但出现no pg_hba.conf entry for host "49.34.151.37" 错误。
我的 POM.xml 如下。

更新：- 我已经检查了与本地 PostgreSQL 服务器相同的应用程序。它工作正常。
【问题讨论】：
这是别人的数据库吗？ 该数据库由 Heroku 提供...我已点击此链接：-devcenter.heroku.com/articles/… 【参考方案1】：我也有同样的问题。我发现了一些可能与这个问题click here 相关的相关资源。
现在你可以更新你的 jdbc url。
jdbc:postgresql://ec2-54-204-18-53.compute1.amazonaws.com:5432/d695rcqcr9r06e&user=poevxwkkkdcuho&password=[password they provide]&ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory
希望这对你有用。
【讨论】：
【参考方案2】：将您的 JDBC 驱动程序升级到
<dependency>
<groupId>org.postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>42.2.2</version>
</dependency>
9.1-901-1.jdbc4 7 年前发布的版本，不支持sslmode 选项。
【讨论】：
我在 pom.xml 中进行了更改，但不会有任何不同的错误。以上是关于无法将 AWS-Postgres 服务器与带有 heroku 托管的 Spring Boot 应用程序连接起来的主要内容，如果未能解决你的问题，请参考以下文章
