当我尝试使用我的凭据(pgadmin iii – postgres sqltool)连接到我的Postgresql服务器时,它工作正常.当我尝试从我的Java应用程序连接时,我得到以下日志.有点奇怪

对此有任何帮助非常感谢,因为这个奇怪的错误我无法进步.
最佳答案
如果您还没有尝试过,请查看您的pg_hba.conf文件.它会被命名为
/etc/postgresql/9.6/main/pg_hba.conf (Ubuntu 16.04)
/var/lib/pgsql/9.3/data/pg_hba.conf (Fedora 20);
您可能必须使用find / -name pg_hba.conf来定位它.
在文件的底部,将METHOD值更改为trust以进行本地测试(有关完整信息,请参阅postgres文档).重新启动postgres以确保所有内容都已开始清理并读取新的参数：
sudo systemctl restart postgresql # ubuntu
希望这能够治愈你的困境.它解决了我在Ubuntu / Fedora上的问题.
