Spring項目我如何訪問JBoss JNDI數據源

Question

以下是我的Spring Project當前的database.xml文件。 有人可以告訴我什么需要更改，以便可以在其中使用JBoss JNDI數據源。我想這樣做，因此不需要包含數據庫用戶，密碼和URL的配置文件。

Answer 1

我假設您可以在JBoss中配置DataSource 。 注意，您必須在應用程序服務器配置中定義其JNDI名稱。 一旦有了名稱，只需將dataSource bean替換為：

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="jdbc/some-name"/>
</bean>

或捷徑：

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/some-name" expected-type="javax.sql.DataSource" />
