实际上,我在两个 tomcat 实例上部署了 grails 应用程序。现在我遇到了一个问题。我的 Quartz 作业需要集群。
我阅读了插件文档,发现可以将 Quartz 作业与数据库结合起来进行集群。
因此,我必须在我的 grails 应用程序中创建一个 hibernate 映射('grails-app/conf/hibernate/hibernate.cfg.xml')。
<?xml version='1.0' encoding='UTF-8'?>
<session-factory>
<mapping resource='Quartz.hbm.xml'/>
</session-factory>
然后我还创建了一个Quartz.hbm.xml。这将为 Quartz 插件创建表。
当我启动我的应用程序时,grails 似乎没有使用 hibernate.cfg.xml 并且没有创建表。
我的想法是问题出在我下面的 Spring Datasource 定义上。
import org.apache.commons.dbcp.BasicDataSource
import org.codehaus.groovy.grails.commons.ConfigurationHolder as CH
// Place your Spring DSL code here
beans = {
dataSource(BasicDataSource) { bean ->
bean.destroyMethod = 'close'
def ds = CH.config.dataSource
// required attributes
if(ds.driverClassName == "com.mysql.jdbc.Driver") {
url = ds.url
username = ds.username
password = ds.password
driverClassName = ds.driverClassName
// optional attributes
minEvictableIdleTimeMillis = 1000 * 60 * 30
timeBetweenEvictionRunsMillis = 1000 * 60 * 30
numTestsPerEvictionRun = 3
testOnBorrow = true
testWhileIdle = false
testOnReturn = false
initialSize = 2
minIdle = 1
maxIdle = 4
validationQuery = "SELECT NOW()"
} else {
url = ds.url
username = ds.username
password = ds.password
driverClassName = ds.driverClassName
}
}
}
现在我有了 hibernate 日志的输出。看起来该文件将被解释。但是解析之后发生了什么?日志中没有任何异常。

有什么想法吗?
最佳答案
这句话让我感到困惑
Then I also created a Quartz.hbm.xml. This one creates the tables for the Quartz Plugin.
我相信您应该使用特定于您的数据库的 src/templates/sql
目录中提供的映射文件。
