我处于这种情况,已经超过两天,但无法使用JNDI获得数据库连接。
我收到以下错误
org.apache.tomcat.dbcp.dbcp2.BasicDataSourceFactory.getObjectInstance Name = myDatabase忽略未知属性:“描述”属性的“我的数据源新”值
我正在使用Tomcat-8
Java-1.8
,Spring-3
和Maven 3.2.5
。
我正在尝试在Tomcat中部署我的Web应用程序。我创建了war并放在TOMCAT / webapp目录中。
数据库的Tomcat / conf / server.xml文件配置
server.xml
<GlobalNamingResources>
<Resource name="jdbc/myDatabase"

Spring Application上下文内容
<jee:jndi-lookup id="monitoringDataSource" jndi-name="jdbc/myDatabase" expected-type="javax.sql.DataSource"/>
web.xml 内容
<resource-ref>

我错过了什么?
我已尝试过所有可能的配置,但没有任何效果。

更新1:
我已从web.xml
删除了描述标记,但我仍然遇到同样的错误。我刚检查了服务器日志,实际错误如下。
我该如何解决这个错误。
java.sql.SQLException:无法创建类''的JDBC驱动程序 连接网址'null'
