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 problem is that Spring Data JDBC does not provide a dialect for Oracle out of the box. See Spring Data JDBC Firebird dialect not recognized for a solution (though you'll need to modify it to work for Oracle).Mark Rotteveel
Hi @MarkRotteveel : thanks very much. I pinged you on that post. How can spring data jdbc 2.0 provide a dialect for mysql but not provide for oracle -- did suddenly spring come to recognize that they don't want to support the very popular oracle out of the box ? OR is that an oversight ?anjanb
I don't know, you should ask the maintainers for Spring Data JDBC that question.Mark Rotteveel
Hi @MarkRotteveel, thank you. I've tweeted them. Hoping to hear from them after the holiday.anjanb

What is happening with the oracle jdbc driver in spring boot 2.3.0.RELEASE ?

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.

The fix:

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:

Some background:

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.

This Dialect resolver fixed my issue with Oracle.

 @Configuration
   public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {
    
        @Override
        public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
            return AnsiDialect.INSTANCE;
        }
    }

Currently spring data jdbc doesn't support oracle dialect You need to define your own dialect resolver Add following class for Oracle Dialect which implements JdbcDialectProvider.

import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.SQLException;
import java.util.Locale;
import java.util.Optional;

import org.springframework.data.jdbc.repository.config.DialectResolver.JdbcDialectProvider;
import org.springframework.data.relational.core.dialect.AnsiDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.ConnectionCallback;
import org.springframework.jdbc.core.JdbcOperations;

public class OracleDialectResolver implements JdbcDialectProvider {

    @Override
    public Optional<Dialect> getDialect(JdbcOperations operations) {
        return Optional.ofNullable(operations.execute((ConnectionCallback<Dialect>) OracleDialectResolver::getDialect));
    }

    private static Dialect getDialect(Connection connection) throws SQLException {
        DatabaseMetaData metaData = connection.getMetaData();
        String name = metaData.getDatabaseProductName().toLowerCase(Locale.ROOT);
        if (name.contains("oracle")) {
            return AnsiDialect.INSTANCE;
        }
        return null;
    }

}

Register your provider by putting a file spring.factories in the META-INF folder of your class path and add the following line.

org.springframework.data.jdbc.repository.config.DialectResolver$JdbcDialectProvider=com.mypackage.jdbctemplate.dialect.OracleDialectResolver //fuly qualified class name of your dialect resolver class

I had exactly the same problem last week.

The change I did in my project was simpler: I just replaced HikariCP dependency with tomcat-jdbc in pom.xml:

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jdbc</artifactId>
    <!-- HikariCP doesn't deals with jdbcDialect properly -->
    <exclusions>
        <exclusion>
            <groupId>com.zaxxer</groupId>
            <artifactId>HikariCP</artifactId>
        </exclusion>
    </exclusions>
    <!-- Dependency removed -->
    </dependency>
    <!-- Dependency to tomcat-jdbc to deal with jdbcDialect -->
    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-jdbc</artifactId>
    </dependency>
    <!--...-->

If I undo this, the exception you posted in title happens again.

Good luck for you.

small update to the already posted answer, for oracle Dialect in Build.gradle

implementation group: 'org.springframework.data', name: 'spring-data-relational', version: '2.1.1'

and then create below class

import org.springframework.context.annotation.Configuration;
import org.springframework.data.jdbc.repository.config.AbstractJdbcConfiguration;
import org.springframework.data.relational.core.dialect.OracleDialect;
import org.springframework.data.relational.core.dialect.Dialect;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcOperations;

@Configuration
public class SpringDataJdbcConfiguration extends AbstractJdbcConfiguration {

  @Override
  public Dialect jdbcDialect(NamedParameterJdbcOperations operations) {
    return OracleDialect.INSTANCE;
  }
}
