Question

我正在尝试使用jdbc postgres driver，sql2o和spark-mvc设置一个简单的java todo-list应用程序来访问postgres数据库。

这是我的sql2o命令，用于设置与数据库的连接：

static Sql2o sql2o = new Sql2o("jdbc:postgresql://localhost:5432/todo-development", "jake", "password");

这些是我正在使用的版本：

compile group: 'org.sql2o', name: 'sql2o', version: '1.5.4'

编译组：＆＃39; org.postgresql＆＃39;，名称：＆＃39; postgresql＆＃39;，版本：＆＃34; 9.4-1201-jdbc41＆＃34;

当我运行我的应用程序时，我得到了这个堆栈跟踪：

Exception in thread "main" org.sql2o.Sql2oException: Could not acquire a connection from DataSource - FATAL: invalid value for parameter "TimeZone": "America/Los_Angeles"

有什么可能导致这种情况的想法吗？

Answer 1

通过重新启动计算机解决了这个问题。有时这是简单的事情。

无法使用JDBC驱动程序和sql2o连接到我的Posgres服务器
