How to fix "Driver does not support get/set network timeout for connections" while connecting to oracle database from spring boot app?

Question

I was trying to connect to my table and insert some data.We are using oracle database. In the code I have used oracle thin driver ojdbc14.I am getting

2018-12-27 11:08:58.810  INFO 16548 --- [           main] com.zaxxer.hikari.pool.PoolBase          : HikariPool-1 - Driver does not support get/set network timeout for connections. (oracle.jdbc.driver.T4CConnection.getNetworkTimeout()I)
2018-12-27 11:08:58.810 ERROR 16548 --- [           main] com.zaxxer.hikari.pool.PoolBase          : HikariPool-1 - Failed to execute isValid() for connection, configure connection test query (oracle.jdbc.driver.T4CConnection.isValid(I)Z).

I am fairly new to spring boot and was actually trying to

do this demo - https://www.devglan.com/spring-jdbc/working-with-springboot-jdbctemplate

only changes I have done is in my pom.xml and application.properties.

Is there any thing else needed for oracle? How i should solve this?All the example I see for oracle in net is with hibernate.Is is necessary to include hibernate approach? Thank you in advance.

Answer 1

That is because you are using a very old version of ojdbc. You should be using the latest versions of the Oracle JDBC driver to connect to your Oracle database.

From a quick test here:

• the warning is still present with version 11.2.0.1
• there is no warning with version 12.1.0.2
• oracle.jdbc.driver.T4CConnection.getNetworkTimeout API is in Oracle JDBC 12.1.0.2(https://docs.oracle.com/database/121/JAJDB/toc.htm).
• but oracle.jdbc.driver.T4CConnection.getNetworkTimeout API is not in Oracle JDBC 11.2.0.1(https://download.oracle.com/otn_hosted_doc/jdeveloper/905/jdbc-javadoc/oracle/jdbc/OracleConnectionWrapper.html)
