Eclipse-plsql连接oracle正常但javajdbc连不上（java.sql.SQLException: ORA-01017: invalid username/password; logon denied）

1、错误现象

java.sql.SQLException: ORA-01017: invalid username/password; logon denied

二、原因

PL/SQL使用的是SERVICE_NAME连接，程序里用了SID连接

三、本次解决方法

两种程序中的连接方法：

SID连接方式：

jdbc:oracle:thin:@<host>:<port>:<SID>

SERVICE_NAME连接方式：

jdbc:oracle:thin:@<host>:<port>/ServiceName
