Spring 引导无法从数据源确定 jdbc url
Spring Boot Unable to determine jdbc url from datasource
我正在构建一个使用 spring 引导的应用程序，需要通过服务而不是 sid 连接到 Oracle DB。
这些是数据源设置：
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@//hostname.companyname.corp:1500/servicename.companyname.com
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.OracleDialect
spring.jpa.properties.hibernate.default_schema=SCHEMA_NAME
我已经探索了关于 tns 连接的另外两个响应：
和
How to connect JDBC to tns oracle
但我遇到了另一个错误：

我正在使用相同的 URL、service_name 和凭据连接到 sqldeveloper 中的数据库，并且可以确认该部分是正确的。我还尝试了以上链接设置中建议的选项
System.setProperty("oracle.net.tns_admin", "C:/ora12/client_1/network/admin");
并设置 url @service_name 具有相同的结果
我完全不知道是什么原因造成的——语法不正确还是其他原因？
有没有其他人有任何建议可能导致它以及可能的解决方案是什么？

将url更改为：
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname.companyname.corp)(PORT=1500))(CONNECT_DATA=(SERVICE_NAME=servicename.companyname.com)))
原来问题是由数据库服务器上 etc/issue 文件的大小引起的。切换到旧的 ojdbc6 驱动程序是一个可选的解决方案，或者减少 linux 框上的 etc/issue 的大小是另一个。
我正在构建一个使用 spring 引导的应用程序，需要通过服务而不是 sid 连接到 Oracle DB。

如果我切换到调试模式，我会得到更多的细节，然后异常发生：
2018-03-01 15:34:21.435 DEBUG 44920 --- [ main] o.s.jdbc.datasource.DataSourceUtils : Fetching JDBC Connection from DataSource 2018-03-01 15:34:21.446 DEBUG 44920 --- [

我正在使用相同的 URL、service_name 和凭据连接到 sqldeveloper 中的数据库，并且可以确认该部分是正确的。我还尝试了以上链接设置中建议的选项
System.setProperty("oracle.net.tns_admin", "C:/ora12/client_1/network/admin");
并设置 url @service_name 具有相同的结果
我完全不知道是什么原因造成的——语法不正确还是其他原因？ 有没有其他人有任何建议可能导致它以及可能的解决方案是什么？

感谢任何建议或帮助！
将url更改为：
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname.companyname.corp)(PORT=1500))(CONNECT_DATA=(SERVICE_NAME=servicename.companyname.com)))
原来问题是由数据库服务器上 etc/issue 文件的大小引起的。切换到旧的 ojdbc6 驱动程序是一个可选的解决方案，或者减少 linux 框上的 etc/issue 的大小是另一个。
