org.postgresql.util.PSQLException: FATAL: нет записи pg_hba.conf для хоста

Question

Я пишу веб-приложение, которое использует Hibernate для подключения к Heroku Postresql. Все работает нормально, когда приложение развертывается в Heroku, но я получаю следующее исключение, когда я запускаю приложение локально.

Caused by: org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host "someip", user "somepassword", database "dbname", SSL off 

Я думаю, проблема в том, что мне нужно включить/настроить Hibernate для подключения к базе данных через SSL. Как я могу это сделать, если это проблема.

Answer 1

Это немного FAQ, хотя в основном для Ruby, а не для пользователей Java. Это covered in the basic PgJDBC documentation. Вы настраиваете SSL как свойство соединения JDBC так же, как и все остальное.

Похожие вопросы:

• How do I configure hibernate ORM on heroku?
• Problems connecting Pentaho Kettle/Spoon to Heroku PostgreSQL using SSL

Answer 2

Другой вариант заключается в изменении вашего JDBC URL, добавив параметр SSL, который будет игнорировать сертификат сервера:

jdbc:postgresql://<host>:5432/<db>?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory 

Обратите внимание, что этот вариант не должен использоваться d для производства.

Answer 3

Вы можете разрешить удаленные подключения к PostgreSQL, добавив следующую строку или похожий на ваш C:\Program Files\PostgreSQL\<version>\data\pg_hba.conf:

host all  all  0.0.0.0/0 md5 

Во всяком случае в производственной среде, вы должны быть осторожны.
