Question

Grails 3（3.0.9）应用程序无法在TC服务器上启动，其中使用其每个JNDI数据源的另外2个Grails 2应用程序正常运行。

似乎在Grails 3中复制我的Grails 2 JNDI设置不起作用（我将其他所有内容保留为默认值，并为我的prod数据源设置指定了driverClassName，dbCreate和jndiName）。

应用程序直接通过JDBC连接到MySQL数据库没有问题。只有JNDI使其崩溃，并出现以下异常（片段）......

Answer 1

你正确的上面没有工作。我按照以下步骤操作，现在正在为我工作。

tomcat context.xml文件定义如下：
```
Resource name="grailsDB"
```

application.yml添加了这个生产数据源。

production:
    dataSource:
        dbCreate: update
        jndiName: java:comp/env/grailsDB

根据https://grails.github.io/grails-doc/3.0.x/ref/Plug-ins/dataSource.html文档创建了grails-app / conf / DataSource.groovy文件。
```
dataSource {
    jndiName = "java:comp/env/grailsDB"
}
```
使用grails war命令创建war文件。
在tomcat中部署并通过添加删除样本数据对其进行测试。

以下是我测试过的软件版本。

APPLICATION STATUS
    Environment: production
    App profile: web
    App version: 0.1
    Grails version: 3.0.3
    Groovy version: 2.4.3
    JVM version: 1.8.0_65

希望这有帮助。

感谢 -SR

Answer 2

在 application.yml 中，我用此值替换了 url ，它对我有用。你可以尝试一样。

QueueProcessor

如何在Grails 3.x中配置JNDI数据源？
