hibernate - Grails 忽略 hibernate.cfg.xml

Question

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？

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。
