Question

我正在将一个glassfish项目转换为IBM WAS Liberty，我很难在访问使用jndi（jdbc / dataphile）在Liberty（server.xml）中配置的连接池时遇到问题。

我连续获得缺少类型com.ibm.ws.rsadapter.jdbc.WSJdbcDataSource 错误。

以下是一些更多细节：

<library id="DB2JCC4Lib">
    <fileset dir="C:/MyApps/db2/jdbc" id="db-fileset" includes="db2jcc4-9.5.jar"/>
</library>

<dataSource id="dataSource" jndiName="jdbc/dataphile" type="javax.sql.DataSource">
    <jdbcDriver libraryRef="DB2JCC4Lib"/>
    <connectionManager minPoolSize="2" numConnectionsPerThreadLocal="10"/>
    <properties.db2.jcc databaseName="DUNDEEPD" id="DataphileProperties" password="username" portNumber="30001" serverName="xxx.xx.xxx.xxx" user="username"/>
</dataSource>

我的堆栈跟踪在下面;

Answer 1

我不是这方面的专家，但此处报道了类似的问题：

https://developer.ibm.com/answers/questions/9498/datasource-issue-on-liberty-in-spring-hibernate-application.html

解决方案需要将其添加到数据源：

<property name="resourceRef" value="true" />
<property name="expectedType" value="javax.sql.DataSource"/>

Answer 2

我确实有足够的理论知道为什么，但这就是我从根本上解决问题的方法：

最初，在我的Spring XML架构配置中，我有以下内容：

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

但我必须将其转换为以下内容：

<bean id="dataSource"  class="org.springframework.jndi.JndiObjectFactoryBean">
      <property name="jndiName" value="jdbc/mydatasource" />
      <property name="lookupOnStartup" value="false"/>
      <property name="cache" value="true" />
      <property name="proxyInterface"  value="javax.sql.DataSource" />
</bean>

基本上建议我必须强制执行此配置更改，这会添加以下属性：

<property name="proxyInterface"  value="javax.sql.DataSource"
