Created a fresh boot project with just jdbc and Oracle jdbc as dependencies
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jdbc</artifactId> </dependency> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc8</artifactId> <version>12.2.0.1</version> </dependency>
I configure the datasource in the application.properties file and run this simple application and it bombs with below stacktrace.

If I run the above code using spring boot 2.2.7.RELEASE, it works just fine -- No exceptions!!
After 2 days, I thought of configuring a mysql datasource on localhost. The same program runs just fine (with spring boot 2.3.0.RELEASE) but this time it used the mysql datasource.
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency>
What is happening with the oracle jdbc driver in spring boot 2.3.0.RELEASE ?
What is mysql jdbc driver doing correctly in spring boot 2.3.0.RELEASE ?
Thank you.

The JDBC Driver is doing just fine.
As you already learned in the comments the problem is that
a) Spring Data JDBC now requires a Dialect
for each database
b) Spring Data JDBC does not ship with a Dialect
for Oracle.
As described in Spring Data JDBC Firebird dialect not recognized and in https://spring.io/blog/2020/05/20/migrating-to-spring-data-jdbc-2-0
you need to provide your own Dialect
implementation right now.
Something like this should work:
class MyOracleDialect extends AnsiDialect {
private static final LimitClause LIMIT_CLAUSE = new LimitClause() {
@Override
public String getLimit(long limit) {
return String.format("FETCH NEXT %d ROWS ONLY", limit);
}
@Override
public String getOffset(long offset) {
return String.format("OFFSET %d ROWS", offset);
}
@Override
public String getLimitOffset(long limit, long offset) {
return String.format("OFFSET %d ROWS FETCH NEXT %d ROWS ONLY", offset, limit);
}
@Override
public Position getClausePosition() {
return Position.AFTER_ORDER_BY;
}
};
@Override
public LimitClause limit() {
return LIMIT_CLAUSE;
}
}
You then need to make the Dialect
available via a DialectProvider
as described in the referenced Stackoverflow question:
So far the Spring Data team does not run their integration tests with an Oracle database. This is because for quite some time it was unclear how to do that in a legal way since all the code including the build infrastructure was open source and Oracle required accepting of all kinds of stuff to use a database instance or their driver.
By now Docker images are available for testing and the JDBC driver is available from Maven Central. It is still a little tricky since the current options for docker images that I am aware of let you choose between an image size of many GBs or a start up time of about 15 minutes.
Anyway there is a community member working on the issue: https://jira.spring.io/browse/DATAJDBC-256
I'm therefore confident that we will be able to fully support Oracle in the near future.
