  • jdbc连接oracle时报错 Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableC

    错误:

     Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure

    Last packet sent to the server was 0 ms ago.)

    解决方法:1、注意驱动包是否正确 驱动类的名字:oracle.jdbc.driver.OracleDriver

                       2、JDBC URL:jdbc:oracle:thin:@dbip:port:databasename

                                 dbip –为数据库服务器的IP地址,如果是本地可写:localhost或127.0.0.1

                                 port –为数据库的监听端口,需要看安装时的配置,缺省为1521。

                               databasename –为数据库的SID,通常为全局数据库的名字。

                            举例如果要访问本地的数据库aaaa,端口1521,那么URL写法如下:
                                  jdbc:oracle:thin:@localhost:1521:aaaa

                       3、username和password 在properties文件中和xml文件中一定要对应上
