postgres服务器拒绝连接到heroku

[英]postgres server refuses to connect to heroku

我已经为要在Heroku上部署的gradle应用程序设置了一个远程postgresql数据库。 在机器上运行我的应用程序时,它可以正常运行。 但是,我很难连接到在Heroku上设置的数据库,因此我认为我只是尝试连接到远程数据库。 这是显示在我的应用日志中的错误:

我读到我需要更改postgres配置文件中的权限,但我一直遇到相同的错误。 windows计算机上修复此问题的最佳方法是什么?

编辑:

我已经建立了一个heroku postgres数据库,看看是否有帮助。 我不确定它是否仍然存在连接问题以及查找主类的问题。 连接到我的原始数据库仍然值得吗? 这是我现在得到的错误:

这是配置类读取的yaml配置的片段:

server:
  type: simple
  applicationContextPath: /application
  adminContextPath: /admin
  connector:
    type: http
    port: 8080

database:
  # the name of your JDBC driver
  driverClass: org.postgresql.Driver

  # the username
  user: someusername

  # the password
  password: somepassword

  # the JDBC URL
  url: jdbc:postgresql://host:port/dbname?user=username&password=password

这是我的procfile

web: java $JAVA_OPTS -Ddw.server.connector.port=$PORT -Ddw.database.user=$JDBC_DATABASE_USERNAME -Ddw.database.password=$JDBC_DATABASE_PASSWORD -Ddw.database.url=$JDBC_DATABASE_URL  $JAVA_OPTS -jar build/libs/mbta-tweets.jar server config.yaml

这条信息:

Caused by: org.postgresql.util.PSQLException: Connection to localhost:5432 refused

建议您尝试连接到Heroku上localhost上的数据库,这当然是不正确的。 您可以显示如何用Java代码配置数据库连接吗?
