所以我正在尝试创建一个grails应用程序,该应用程序挂钩到主键列为UUID的现有数据库中:

      Column       |            Type             | Modifiers 
-------------------+-----------------------------+-----------
 uuid              | uuid                        | not null

但是,当我设置我的数据源时:

class DataStore {
UUID     uuid
...
static mapping = {
...
     id generator: 'assigned', name: 'uuid', type: 'pg-uuid'
}

它坚持认为uuid列是varchar(255).我不知道我需要做些什么来让它认识到uuid列是一个uuid列,并且我已经尝试在src/groovy /中放置一个UserType类,但这并没有解决任何问题.

我也试图用inet列做同样的事情,但我在这里一步一步.

这里有什么帮助？我很快就结束了.

编辑:我发现这个grails使用uuid作为id并映射到二进制列,但它只是在我尝试运行它时抛出此错误:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.codehaus.groovy.grails.exceptions.GrailsDomainException: Error …

所以我在我的本地机器上运行STS的Grails应用程序,并且我正在尝试将其部署到CentOS/Tomcat服务器VM.我认为我正确安装了Groovy和Grails,或者至少我现在可以通过将它们添加到/ etc/bashrc中的路径来从控制台运行它们.但是,当我获取我编译的.war文件,并将其放入Tomcat服务器的webapp目录并重新启动服务器时,它会抛出此错误:
