Using Weblogic Data source in Spring Boot

Question

I use data source from Weblogic in Spring Boot project. In application.properties, I added data source jndi name spring.datasource.jndi-name=jdbc/student. But I got NoInitialContextException.

When I tried at the following, it works.

spring.datasource.url=jdbc:mysql://localhost/testdb
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

I would like to know how to override the default InitialContext information. I want to update weblogic server information such as t3://127.0.0.1:7001, username and password.
