【问题描述】：

在此错误出现之前“我记得”的最后一件事是更新到 openjdk8

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。认为我做了一些关闭这个内存数据库的事情是否正确？我该如何解决这个问题？

【参考方案1】：

放H2方言

dialect = "org.hibernate.dialect.H2Dialect"

在 DataSource.groovy 文件的 dataSource 块中。它应该可以解决您的问题。

确保您没有遇到This 问题。
