Grails部署问题（WAR和Tomcat）

Question

我正在远程服务器上部署Tomcat 6下的WAR。 现在，如果我在我的本地机器上进行部署，一切正常。 远程部署会触发一组非常不友好的异常。

我正在使用HSQLDB作为数据库。

Tomcat作为服务运行，因此不应存在任何权限问题。 我是否需要更改某些内容的权限（如果是这样，因为我找不到尝试访问权限）？ 我是否可以在Grails中设置配置选项，以便不记录或重定向日志记录？

Answer 1

这不是关于日志记录，而是关于“prodDB.properties”。 你得到一个FileNotFoundException，因为它无法写入（或可能重命名）它。 运行应用程序的用户必须在创建HSQLDB数据库文件的目录中没有写入权限。

默认配置使用相对路径，因此它会在应用程序启动的任何位置写入：

production {
    dataSource {
        dbCreate = "update"
        url = "jdbc:hsqldb:file:prodDb;shutdown=true"
    }
}

一个解决方法是在DataSource.groovy中对路径进行硬编码：

production {
    dataSource {
        dbCreate = "update"
        url = "jdbc:hsqldb:file:/some/writeable/folder/prodDb;shutdown=true"
    }
}

更好的方法是在Config.groovy中启用外部配置文件：

grails.config.locations = ["classpath:${appName}-config.groovy"]

并创建包含foo-config.groovy

dataSource {
    url = "jdbc:hsqldb:file:/some/writeable/folder/prodDb;shutdown=true"
}

并将foo-config.groovy放在Tomcat的类路径中的$ TOMCAT_HOME / lib中（将foo更改为您的应用名称）。 通过这种方式，您可以将战争部署到多个位置，并且只需配置文件覆盖，而不是在Config.groovy中对单个值进行硬编码。

当我升级到Windows 7时，我突然遇到了这个问题。我一直在使用快捷方式启动Tomcat，并将“Start In”目录设置为普通的“C：\\”。 Windows 7不允许非管理员用户写入此目录。 我创建了一个名为“TomcatData”的用户主目录的子目录，并改变了我的快捷方式，从那里启动Tomcat。 现在一切都很好。
