问题描述

我在Heroku上拥有主机spring-boot应用程序，并添加了Heroku-postgres的附件.他们向我提供了托管在AWS-EC2上的数据库凭证.我试图将我的spring boot应用程序与由Heroku提供并托管在AWS-EC2上的数据库连接，但出现错误no pg_hba.conf entry for host "49.34.151.37".

I have host spring-boot application on Heroku and add Add-ons of Heroku-postgres. They provide me database credential which is hosted on AWS-EC2. I am trying to connect my spring boot application with that database which provided by Heroku and hosted on AWS-EC2 but I got an error as no pg_hba.conf entry for host "49.34.151.37".

我的POM.xml如下.

My POM.xml is as below.

现在您可以更新您的jdbc网址.

For now you can update your 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
