一、
Driver class 'oracle.jdbc.driver.OracleDriver' could not be found, make sure the 'Oracle' driver (jar file) is installed.
oracle.jdbc.driver.OracleDriver

缺少Oracle JDBC jar包,将ojdbc-x.jar 放在lib目录下

二、
Error connecting to database: (using class oracle.jdbc.driver.OracleDriver)
Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

jdbc连接数据库的时候,需要使用数据库的sid_name,而不是数据库的services_name
