Question

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。这很奇怪

file_get_contents('php://input');

.properties文件

对此的任何帮助都非常感谢，因为这个奇怪的错误，我无法进步。

如果您还没有尝试过，请查看您的pg_hba.conf文件。它将被命名为

/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值更改为信任以进行本地测试（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清理干净并读取新的参数：

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。

引起：org.postgresql.util.PSQLException：致命：用户密码验证失败＆＃34; admin＆＃34;
