我可以使用tns文件从plsql连接到数据库
现在我想使用JDBC从我的Java连接到数据库.
我搜索谷歌,我发现我必须使用此连接字符串:
"jdbc:oracle:thin:@//host:port))/tnsfile)";
我的电脑名是myPC
在tnsfile中写入的端口是5151
所以我尝试了这个连接String
"jdbc:oracle:thin:@//myPC:5151))/tnsfile"
但我得到了这个例外
java.sql.SQLRecoverableException: IO ERROR: SO Exception was generated
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:
