Question

我正在使用grails独立插件来创建一个独立的grails应用程序，但我得到一个jdbc h2异常。似乎数据库不是在运行时创建的。

我该如何解决这个问题？

这里有例外

org.h2.jdbc.JdbcSQLException: Table "COMPANY" not found; SQL statement:
select this_.id as id15_0_, this_.version as version15_0_, this_.name as name15_0_ from company this_ limit ? [42102-164]

Answer 1

H2将创建数据库，它可能不会创建您期望的架构。您可以在DataSource.groovy中将以下内容添加到您的URL中：

INIT=CREATE SCHEMA IF NOT EXISTS TEST

所以你有类似的东西：

url = jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000;INIT=CREATE SCHEMA IF NOT EXISTS TEST

虽然有些旧，但将来可以帮助其他人，就我而言，只是其中不包含变更日志，因此经过研究

可以帮助我理解类似问题的链接 how to create a standalone grails app with h2 db by using standalone plugin?

说，我创建了一个新迁移，并包含了所生成的迁移，它的工作就像一个魅力……

如何使用独立插件创建一个带有h2 db的独立grails应用程序？
