Spring Boot无法从datasource确定jdbc url

Question

我正在使用spring boot构建应用程序,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

我已经探讨了关于tns连接的另外两个响应: 通过TNS连接Oracle无法正常工作 以及 如何将JDBC连接到tns oracle

但是我遇到了一个不同的错误:

org.springframework.jdbc.support.MetaDataAccessException:无法获取用于提取元数据的Connection; 嵌套异常是org.springframework.jdbc.CannotGetJdbcConnectionException:无法获取JDBC连接;

如果我切换到调试模式,我会得到更多细节,然后发生异常:

我使用相同的URL,service_name和凭据连接到sqldeveloper中的DB,并且可以确认该部分是正确的.我也尝试过以上链接设置中建议的选项

System.setProperty("oracle.net.tns_admin", "C:/ora12/client_1/network/admin");

并使用相同的结果设置url @service_name

我完全迷失了它可能是什么原因 - 语法错误或其他什么？是否有其他人有任何可能导致它的建议以及可能的解决方案是什么？

感谢任何建议或帮助!

Answer 1

事实证明，该问题是由数据库服务器上的 etc/issue 文件的大小引起的。切换到较旧的 ojdbc6 驱动程序是一种可选的解决方案，或者减少 Linux 机器上的 etc/issue 的大小是另一种解决方案。
