java - JDBC Oracle 属性文件

Question

我正在尝试通过下面的一些示例来学习 Spring MVC:

http://krams915.blogspot.com/2012/01/spring-mvc-31-jqgrid-and-spring-data_1887.html

我的项目在 MySQL 中运行良好且令人满意，但我需要尝试让它在 Oracle 中运行。我毫不费力地移植了数据库。 oracle xe 服务器是 11g 第 2 版。服务器在同一台机器 (localhost) 上运行，我可以使用以下信息使用 SQL 开发人员连接到它。

我的属性文件中有以下内容:

#oracle
app.jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
app.jdbc.url=jdbc\:oracle\:thin\:@localhost\:1521\:DATABASENAME
app.jdbc.username=DATABASENAME
app.jdbc.password=PASSWORD

#mysql
#app.jdbc.driverClassName=com.mysql.jdbc.Driver
#app.jdbc.url=jdbc\:mysql\://localhost/DATABASENAME
#app.jdbc.username=USERNAME
#app.jdbc.password=PASSWORD

就像我说的，取消对 MySQL 的注释它工作正常，不确定 Oracle 设置哪里出了问题。

我得到的错误

Answer 1

如果您使用的是 Oracle XE，数据库名称应始终为 XE。您要使用的用户名似乎不太可能也是 XE - 您是否真的创建了一个名为 XE 的用户？假设您创建的拥有所有数据库对象的用户不是 XE，配置应该类似于

app.jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
app.jdbc.url=jdbc:oracle:thin:@localhost:1521:XE
app.jdbc.username=USERNAME
app.jdbc.password=PASSWORD
