我使用 WebSphere 8.5.5 Liberty 配置文件来部署一个应用程序,该应用程序使用通过 jndi 定义和公开的数据源。但我无法使用我的应用程序中的数据源。我的 server.xml 看起来像这样:
<server description="new server">
<!-- Enable features -->
<featureManager>
<feature>jsp-2.2</feature>
<feature>jndi-1.0</feature>
<feature>ejbLite-3.1</feature>
<feature>jdbc-4.0</feature>
</featureManager>
<dataSource id="mssqlserver" jndiName="jdbc/sqlserver_prod" type="javax.sql.DataSource">
<jdbcDriver libraryRef="MSJDBCLib"/>
<connectionManager numConnectionsPerThreadLocal="10" id="ConnectionManager" minPoolSize="1"/>
<properties.microsoft.sqlserver username="sa" password="" databaseName="PROD"
serverName="10.211.55.4" portNumber="1433"/>
</dataSource>
<library id="MSJDBCLib">
<fileset dir="/Users/alter/Devel/sqlserver" includes="sqljdbc4.jar"/>
</library>
<httpEndpoint id="defaultHttpEndpoint"
host="0.0.0.0"
httpPort="9080"
httpsPort="9443" />
<application id="ee1" location="/Users/alter/Devel/xxxx/src/ear/target/ee1-ear.ear" name="ear_ear_exploded" type="ear" >
<classloader delegation="parentLast" commonLibraryRef="MSJDBCLib" />
</application>
<application id="ee1-web" location="/Users/alter/Devel/xxxx/src/web/target/ee1-web" name="web_exploded" type="war" />
</server>
我使用这个spring配置文件来注入数据源:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<!-- START CONFIG DS -->
<bean id="dataSourcePROD" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="jdbc/sqlserver_prod"/>
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSourcePROD"/>
<property name="mapperLocations" value="classpath*:mappers/**/*.xml"/>
</bean>
<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory"/>
</bean>
<bean id="genericMapper" class="org.mybatis.spring.mapper.MapperFactoryBean" abstract="true">
<property name="sqlSessionTemplate" ref="sqlSessionTemplate"/>
<property name="addToConfig" value="true"/>
</bean>
</beans>
Spring 能够从 JNDI 中找到我的“数据源”对象,但它不能将传递的对象转换为 javax.sql.Datasource。实际的例外是:
org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'com.ibm.ws.jdbc.DataSourceService' to required type 'javax.sql.DataSource' for property 'dataSource';
注意 1:我没有提到可部署工件(ear、wars 等)中的 jdbc 驱动程序
我在 server.xml 中缺少一些用于数据源定义的配置参数???。
