ojdbc7-12.1.0.1.jar    
apache-tomcat-8.5.31
jdk-8u172-windows-x64

Spring 配置

<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
     <property name="driverClassName" value="oracle.jdbc.OracleDriver" />
     <property name="url" value="${database.connection.url}" />
     <property name="username" value="${database.user}" />
     <property name="password" value="${database.pwd}" />
     <property name="initialSize" value="${database.pool.initialSize}" />

</bean>

database.connection.url=jdbc:oracle:thin@X.X.X.X:1521:DATABASE

异常:

Caused by: org.hibernate.exception.GenericJDBCException: Unable to acquire JDBC Connection
    at org.hibernate.exception.internal.StandardSQLExceptionConverter.convert(StandardSQLExceptionConverter.java:47)
Caused by: java.sql.SQLException: Cannot create JDBC driver of class 'oracle.jdbc.OracleDriver' for connect URL 'jdbc:oracle:thin@X.X.X.X:1521:DATABASE'

我试图将驱动程序jar 放在tomcat 的lib 文件夹中，但同样的错误

我在 Wildfly 10.1 上也遇到了错误。

Answer 1

我看到您指的是 Oracle 7 jar 中的错误包。使用 OracleDriver 类名如下 oracle.jdbc.driver.OracleDriver

<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />

您始终可以打开 jar 并找到 OracleDriver 的类:
