I am trying to learn Spring MVC by following through some of the examples at:

I have the project running fine and happy in MySQL, but I need to try and get this running in Oracle. I have ported the database no sweat. The oracle xe server is 11g release 2. The server is running on the same machine (localhost) and I am able to connect to it using SQL developer using the information below.

我的项目在 MySQL 中运行良好且愉快，但我需要尝试在 Oracle 中运行它。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（本地主机）上运行，我可以使用 SQL 开发人员使用以下信息连接到它。

I have the following in my properties file:

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

Like I said, uncommenting the MySQL it works fine, not sure where I am going wrong with the Oracle settings.

就像我说的，取消对 MySQL 的注释它可以正常工作，但不确定 Oracle 设置哪里出了问题。

The error I'm getting

我得到的错误

If you are using Oracle XE, the database name should always be XE. It seems unlikely that the username that you want to use is XEas well-- did you really create a user named XE? Assuming that the user that you created to own all the database objects is not XE, the configuration should be something like

如果您使用的是 Oracle XE，则数据库名称应始终为XE. 您想要使用的用户名似乎不太可能XE- 您真的创建了一个名为 的用户XE吗？假设您创建的拥有所有数据库对象的用户不是XE，那么配置应该类似于

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

I don't believe you should have those Windows slashes in the connection URL. (I don't believe it's correct for MySQL, even if it "works".) It ought to look like this:

我不相信你应该在连接 URL 中有那些 Windows 斜杠。（我不相信它对 MySQL 是正确的，即使它“有效”。）它应该是这样的：

app.jdbc.url=jdbc:oracle:thin:@localhost:1521:DATABASENAME

You'd get more help here if you could post the complete stack trace of the exception you're getting or log messages from Spring.

如果您可以发布您收到的异常的完整堆栈跟踪或记录来自 Spring 的消息，您将在此处获得更多帮助。
