Question

我正在尝试在tomcat 7.0.42上部署我的grails（2.2.1）应用程序。所以我按照grails网站上link中给出的步骤进行了操作。但是当我尝试从Tomcat Web应用程序管理器启动应用程序时，我在tomcat控制台上看到以下错误日志：

gistered.

当通过run-app命令（在intellij中）运行时，应用程序运行正常。

另外，如果我们从日志中看到这一行：Cannot create PoolableConnectionFactory (Database may be already in use: "Locked by another process". Possible solutions: close all other connection(s); use the server mode [90020-164])，它表示该数据库正在被其他进程使用。但是，这不可能发生，因为数据库是HSQLDB，它是grails应用程序的内部，并且没有使用其他外部DBMS。

我肯定会赞成（并且如果它是最终的那样接受）解决上述问题的任何解决方案（或至少给出解决方向）。

修改这是我的DataSource.groovy

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

        }
    }
    test {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
        }
    }
    production {
        dataSource {
            dbCreate = "update"
            url = "jdbc:h2:file:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
            pooled = true
            properties {
               maxActive = -1
               minEvictableIdleTimeMillis=1800000
               timeBetweenEvictionRunsMillis=1800000
               numTestsPerEvictionRun=3
               testOnBorrow=true
               testWhileIdle=true
               testOnReturn=true
               validationQuery="SELECT 1"
            }
        }
    }
}

Answer 1

url = "jdbc:h2:file:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000"

指的是H2 file数据库。你是否可以尝试在内存prodDb中使用，如果意图不是要引用文件数据库？

url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000"

Answer 2

因为“grails war”命令生成war文件，默认情况下使用 DataSource.groovy 中定义的生产环境。也许生产数据库还没有工作，所以你可以尝试运行“grails test war”来与你的测试数据库建立战争。

在tomcat上部署grails应用程序时创建名为'transactionManagerPostProcessor'的bean时出错
