无法使用Spring Boot和Hibernate连接到Oracle

Question

我有一个使用Postgres的Spring Boot应用程序(1.2).今天我正在尝试将其切换到Oracle,但是当我尝试连接时,我得到一个异常,说:

java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection 

在那之下,

Caused by: java.net.ConnectException: Connection refused

当然,这看起来像是糟糕的凭据,但我知道它们很好,而且他们在Oracle SQL Developer中工作得很好.我很困惑.这是我的属性文件条目:

# Properties for Hibernate and Oracle
spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@//earth-db-11:5121/stardev
spring.datasource.username=ops$abcdefg
spring.datasource.password=mypassword
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect

我唯一的想法就是用户名中有一个$,我试图转义并在其周围加上双引号.

有任何想法吗？

谢谢...

更新:

非常感谢BonanzaOne,我的端口号错了.更正会导致新错误:

java.sql.SQLRecoverableException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

当然,我查了一下,但我没有按照它告诉我的说法:

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Cause: The listener received a request to establish a connection to a database
or other service. The connect descriptor received by the listener specified a
service name for a service (usually a database service) that either has not    yet
dynamically registered with the listener or has not been statically configured
for the listener. This may be a temporary condition such as after the listener
has started, but before the database instance has registered with the listener.

不过,SQL Explorer连接正常.

该异常意味着Oracle侦听器未启动,或者您尝试连接到不存在/不可访问的侦听器.

我的猜测是你尝试错误的端口"5121".Oracle默认端口是1521.

你可以尝试一下,看看会发生什么？

从FAQ中,基本上有两种组成JDBC字符串URL的方法:

旧语法

JDBC:预言:瘦:@ [HOST] [:端口]:SID

新语法

JDBC:预言:瘦:@ // [HOST] [:端口]/SERVICE

我的猜测是你使用了错误的语法-SID /服务名称组合,换句话说,你使用的是需要SERVICE名称的新语法,但是你使用SID名称来执行它.

试试这个:jdbc:oracle:thin:@ earth-db-11:1521:stardev

或者找出服务名称并将其应用于您正在使用的新语法,而不是SID名称.
