jboss 7 如何动态添加数据源 [英] How to dynamically add datasources to jboss 7

问题描述

我有一个应用程序，它为应用程序的每个实例动态添加数据库，然后在 JBoss 5 上将数据源文件写入部署文件夹，以便应用程序可以使用新数据库(并且是锁定它).

I have an application which dynamically adds databases for each instance of the application, and which then, on JBoss 5 would write a datasource file out into the deploy folder, so that the application could make use of the new database (And be locked down to it).

在 JBoss 7 中，数据源配置在 standalone.xml 中.更重要的是，如果我在这个文件中输入新的数据源，它们似乎不会被读取，也没有可用的数据源.

In JBoss 7 the datasource configuration is inside standalone.xml. And more importantly if I enter new datasources into this file, they don't seem to get read and no datasource is available.

有人知道我们升级到 JBoss 7 后如何重现这种行为吗?

Does anyone have any idea how I can reproduce this behaviour once we upgrade to JBoss 7?

推荐答案

在较新版本的 JBoss AS7 中 -ds.xml 策略将起作用.

In newer version of JBoss AS7 -ds.xml strategy will work.

但是管理 CLI 为您提供了另一种执行方式(因为它们不会有扫描延迟，因此可能是更推荐的方式).

But management CLI offer you another way to perform it (as they will be no scanning delay it is probably a more recommended way).

您可以使用命令文件调用 jboss-cli.sh(有关如何操作的详细信息，请参见此处:http://planet.jboss.org/post/how_to_create_an_manage_datasources_in_as7) 或者你可以直接使用原生 API (https://docs.jboss.org/author/display/AS71/The+native+管理+API).

You can either call jboss-cli.sh with command file (detail on how to do it can be found here: http://planet.jboss.org/post/how_to_create_an_manage_datasources_in_as7) or you can use the directly the native API (https://docs.jboss.org/author/display/AS71/The+native+management+API).

后面的方法除了 add 之外，还可以查询现有的数据源并进行更新.

With the later method in addition to add, you will be able to query the existing data sources and update them.
