訪問MySQL的數據源豆春季

Question

我想從我的Spring項目（在springtoolsuite）內創建MySQL數據源豆，我想 訪問MySQL JNDI（由JBoss application server運行）。

我的bean聲明

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean" scope="singleton" > 
<property name="jndiName" value="java:/MySqlDS" /> 
<property name="resourceRef" value="true" /> 

而且從JBoss的控制檯：

java: Namespace 
+- MySqlDS (class: org.jboss.resource.adapter.jdbc.WrapperDataSource) 

然而，當我跑我的測試應用程序，我得到了下面。我做錯了什麼？

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in file [/workspace-sts/test1/cspringbean.xml]: Invocation of init method failed; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial

Answer 1

javax.naming.NoInitialContextException： 需要 環境或系統屬性指定的類名，或 一個applet參數，或在 應用程序資源文件： java.naming.factory。初始

此消息的堆棧跟蹤使我相信，要麼你沒有設立一個JNDI數據源池在JBoss中或您的JNDI名稱不正確。同時檢查。

更新：您的應用程序如何使用JBOSS進行JNDI查找？如果您沒有部署在應用服務器中，那麼您應該使用DriverManagerDataSource，而不是JNDI數據源。

Answer 2

我也建議採取看看JEE命名空間，而不是定義工廠bean

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/MyDataSource"/>
