我已配置连接池以获取数据库连接。
配置： Tomcat 8，dbcp 2.X和Jdk 1.8.0_161
资源在context.xml中配置如下：
<Resource
name="jdbc/bankdb"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
maxActive="100"
maxIdle="30"
minIdle="30"
maxWait="90000"
removeAbandoned="true"
removeAbandonedTimeout="60"
username="root"
password=""
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:@servername:port:database"
/>
我在ojdbc6.jar文件夹中添加了tomcat/lib。但仍然得到以下例外。
