context.xml配置了数据源。。。正常。
服务器重启一次，数据源消失了。
肯定就报错了。。
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/configs/beans-jpa.xml]: Cannot resolve reference to bean 'adDataSource' while setting bean property 'dataSource';
忘了是改哪个了。。。
------解决方案--------------------
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
你的数据库配置里，driver class没配
------解决方案--------------------
是这个没有了？
- Java code
<Resource auth = "Container" name = "jdbc/adbDataSource" type = "javax.sql.DataSource" driverClassName = "oracle.jdbc.driver.OracleDriver" url = "jdbc:oracle:thin:@10.xx.xx.xx:1521:xxx" username = "ad" password = "adxxx" maxIdle = "5" maxWait = "5000" maxActive = "10"/>
