java - 无法使用 JDBC 驱动程序和 sql2o 连接到我的 Posgres 服务器

Question

我正在尝试设置一个简单的 java 待办事项列表应用程序以使用 jdbc postgres driver 访问 postgres 数据库, sql2o和 spark-mvc .

这是我用于建立数据库连接的 sql2o 命令:

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

这些是我使用的版本:

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

编译组:'org.postgresql'，名称:'postgresql'，版本:"9.4-1201-jdbc41"

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"
