Grails 抛出错误 hbm2ddl.SchemaExport - HHH000389：不成功

Question

出现此错误前的最后一件事 "I remember" 是更新到 openjdk8

Error 2015-01-12 14:19:44,751 [localhost-startStop-1] ERROR hbm2ddl.SchemaExport  - HHH000389: Unsuccessful: create table post (id bigint generated by default as identity, version bigint not null, content varchar(255) not null, limit integer not null, posted_date timestamp not null, poster varchar(255) not null, title varchar(255) not null, primary key (id))

环境

Ubuntu 14.04
Grails 2.4.4
javac 1.8.0_25

数据源

dataSource {
    pooled = true
    jmxExport = true
    driverClassName = "org.h2.Driver"
    username = "sa"
    password = ""
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
//    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
    cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
    singleSession = true // configure OSIV singleSession mode
    flush.mode = 'manual' // OSIV session flush mode outside of transactional context
}

development {
        dataSource {
            dbCreate = "create-drop" // one of 'create', 'create-drop', 'update', 'validate', ''
            url = "jdbc:h2:mem:devDb;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE"
        }
    }

我是 Grails 的新手。认为我已经做了关闭这个内存数据库的事情是正确的吗？我该如何解决这个问题？

Answer 1

输入H2方言

dialect = "org.hibernate.dialect.H2Dialect"

在 DataSource.groovy file.It 的数据源块中应该可以解决您的问题。

确保您没有遇到 This 问题。
